Cheapest FX Broker in Europe (2026):
EUR → USD Conversion Costs Ranked
Updated August 2026 · Six brokers ranked · Every figure traced to a primary fee schedule
There is no single cheapest FX broker in Europe. There is a break-even. Percentage fees win on small conversions; a flat minimum wins on large ones, and the crossover sits at roughly USD 1,300 per conversion. This page ranks six brokers on what they actually charge, shows where the crossover falls for each one, and names the platforms that dodge the question rather than pricing it well.

TL;DR
- Converting a few hundred at a time: Trading 212 at 0.15% with no minimum is the cheapest per conversion in this roster.
- Converting four figures or more: Interactive Brokers, where a spot FX order costs a flat USD 2.00 minimum that keeps shrinking as a share of the amount.
- Not converting at all: buy EUR-denominated UCITS ETFs and the broker-level FX question disappears.
- Fewer, larger conversions beat monthly micro-conversions on every broker in the table.
- Reading a headline percentage without checking whether a per-order minimum applies underneath it.
- Converting on every deposit instead of in planned batches.
- Two-leg conversions, where the markup is charged twice because no direct rate is quoted.
- Assuming “no FX fee” means no conversion charge exists. On at least one platform in this comparison, a markup exists in the contract and its size is not published anywhere.
What “cheapest FX” actually means — and how we judged it
FX efficiency is not the headline markup percentage. It is the markup, plus any per-order floor, plus how many times the workflow forces you to pay it. The criteria below are what determine how much of your capital reaches the market.
- What is the stated markup, and is it a rate or a floor?
- Is there a minimum charge per conversion?
- Is the same rate charged in both directions?
- Does a conversion without a direct quoted pair cost the markup twice?
- Does the fee apply to dividends and corporate action proceeds?
- Can you hold EUR and USD in separate balances?
- Is conversion explicit, or automatic on execution?
- Can you choose the instrument’s trading currency per order?
- Does recurring investing or rebalancing force a conversion?
Percentage or flat fee: where the crossover sits
Almost every comparison of European FX costs ranks brokers by percentage and stops there. That produces the wrong answer at retail sizes, because the cheapest published percentage in Europe sits underneath a flat minimum.
Interactive Brokers prices currency conversion two different ways, and they are not interchangeable. Automatic conversion costs 3 basis points (0.03%) of trade value, applied when you trade an instrument in a foreign currency without converting first. A manual spot FX order costs from 0.20 basis points, with a minimum of USD 2.00 or equivalent per order.
That 0.20 basis point rate is the number quoted in most comparisons, and it is real — but at retail size it never applies. A conversion has to reach roughly USD 100,000 in a single order before 0.20 basis points exceeds USD 2.00. Below that, the floor is the price. The practical IBKR FX cost for almost every European retail investor is therefore USD 2.00 per conversion, flat.
| Conversion size | 0.15% (Trading 212) | Flat USD 2.00 (IBKR spot FX) | Cheaper |
|---|---|---|---|
| 500 | 0.75 | 2.00 — an effective 0.40% | Trading 212 |
| 1,000 | 1.50 | 2.00 — an effective 0.20% | Trading 212 |
| 1,333 | 2.00 | 2.00 — an effective 0.15% | Break-even |
| 5,000 | 7.50 | 2.00 — an effective 0.04% | IBKR |
| 25,000 | 37.50 | 2.00 — an effective 0.008% | IBKR |
Divide USD 2.00 by each broker’s markup and you get the conversion size above which IBKR’s flat minimum becomes the cheaper option:
- vs Trading 212 at 0.15% — about 1,300 per conversion
- vs Saxo and DEGIRO at 0.25% — about 800
- vs Lightyear at 0.35% — about 570
- vs XTB at 0.5% — about 400, and about 200 where the conversion runs through two legs
Our arithmetic on published figures, shown for comparison and not quoted as any broker’s fee. IBKR’s minimum is stated as USD 2.00 or equivalent, so treat the sizes above as approximate rather than exact euro thresholds.
What FX drag actually is — and why it compounds
Most investors focus on commissions. For a European investing regularly into USD assets, conversion is the dominant cost. It rarely appears as a line item on a statement, because on several platforms it is embedded in the price you receive.
- The markup — the rate you receive is worse than the reference rate the broker applied it to.
- Per-order minimums — a floor turns a cheap percentage into an expensive one on small amounts.
- Conversion frequency — twelve conversions a year against three is a large long-term difference on any pricing model.
- Embedded conversion — where the charge is included in the transaction price rather than billed separately, you never see it.
- Two-leg routing — where no direct pair is quoted, the markup can apply at each step.
- Every deposit converted at a markup is that much less capital going to work.
- The shortfall never catches up — it starts compounding from a smaller base immediately.
- Over 20 years or more, a small repeated markup behaves like an additional annual fund cost.
- The behavioural cost is the largest one: if funding feels expensive, consistency collapses.
Hidden FX events: it’s not just when you buy
Most guides frame FX as a deposit-and-buy problem. That is incomplete. A broker can look cheap on your first purchase and still apply conversion charges across the whole life of the position — and the treatment differs sharply between platforms.
- Buying a foreign-currency asset — conversion is triggered if you hold only a EUR balance and did not convert first.
- Recurring orders — where a plan runs against a base-currency balance, each scheduled execution can carry its own conversion.
- Portfolio tools — Trading 212 holds Pie cash in the account’s primary currency, and conversions into and out of a Pie are charged at 0.15%, including dividend reinvestments inside one.
- Selling back to EUR — without multi-currency balances, proceeds convert immediately at the broker’s rate.
- Income conversion — dividends and coupons arriving in a foreign currency are converted on single-currency accounts. This is where platforms diverge most: Trading 212 states that dividend distributions are exempt from its currency exchange cost, while Trade Republic publishes a margin specifically for converting foreign-currency income.
- Rebalancing — trading across currency lines converts on both legs unless you can hold both currencies.
EUR ETF does not mean “no USD exposure”
Three currency concepts are often confused. They are independent of each other, and mixing them up leads to either overpaying on FX or misunderstanding your portfolio’s actual risk.
| Concept | What it means | Why it matters |
|---|---|---|
| Broker FX fee | The markup your broker charges to convert EUR into USD, or the reverse | Avoidable — choose a multi-currency broker, batch your conversions, or buy EUR-denominated instruments |
| Trading / listing currency | The currency used to buy or sell the ETF on a stock exchange | Determines whether your broker needs to convert your cash before placing the order |
| Underlying currency exposure | The currencies of the actual assets held inside the ETF | Not removed by the trading currency. A EUR-listed UCITS MSCI World ETF still holds USD-denominated stocks. Your portfolio is exposed to USD — you are just not paying a spread to acquire that exposure at the broker level. |
Six European brokers, ranked on EUR → USD conversion cost
Ranked on published conversion cost and on how much control you have over when you pay it. Ranking is independent of whether we have a commercial relationship with the broker.
| # | Broker | Published conversion cost | What decides the ranking |
|---|---|---|---|
| 1 | Trading 212 | 0.15%, no minimum | The cheapest rate here with no per-order floor, so it stays cheap on small conversions. Stated as never more than 0.15%, including at weekends. Dividend distributions are exempt from the charge. Selecting the instrument’s currency per order can avoid conversion entirely. The exception is Pie cash: moving money into or out of a Pie is charged at 0.15%, including dividend reinvestments inside one. |
| 2 | Interactive Brokers | Spot FX from 0.20 bps, minimum USD 2.00 per order · auto-convert 3 bps | Unbeatable above the break-even and genuinely multi-currency: convert once, hold USD, buy repeatedly without converting again. Below roughly 1,300 per conversion the USD 2.00 floor makes it more expensive than the percentage brokers. Two separate mechanisms — the flat-minimum spot order and the 0.03% automatic conversion — and it matters which one you use. |
| 3 | Saxo | 0.25% | A clear published rate at the cheaper end. Verified on the Dutch, Belgian and French schedules; we have not read the equivalent line on every other Saxo entity, so treat 0.25% as confirmed for those three markets rather than pan-European. On the Belgian schedule it is applied to the transaction tariff, exchange tax, withholding tax and other costs on non-EUR accounts. |
| 4 | DEGIRO | AutoFX 0.25%, included in the transaction price · Manual FX €10.00 + 0.25% | The same headline rate as Saxo, ranked below it because of how you pay it. AutoFX is the default and is embedded in the buy or sell price rather than billed separately, and it converts on corporate actions and coupon payments too. The Manual FX option lets you hold foreign currency and choose your moment, but the €10.00 charge on top of 0.25% makes it uneconomic at retail conversion sizes. The €10.00 + 0.25% manual line appears on the Dutch, German, French, Irish and Swiss schedules. DEGIRO is the trading name of flatexDEGIRO Bank Dutch Branch, the Dutch branch of flatexDEGIRO Bank SE. |
| 5 | Lightyear | 0.35% on the interbank rate | More expensive per conversion than everything above it, and included because the workflow is right: separate currency balances, explicit conversion, one rate covering both automatic and manual conversion. 0.35% is the rate on the EU entity. Lightyear publishes different rates for its UK entities, so a single “Lightyear FX rate” is wrong for two of the three. Portuguese residents pay a stamp duty of 4% of the conversion fee, which grosses 0.35% up to 0.364% effective. |
| 6 | XTB | 0.5% of the mid rate — and 0.5% twice on a two-leg conversion | The most expensive published rate in this roster, applied at the moment of the trade on real stocks and ETFs. The detail that matters is below: where no direct rate is quoted between your account currency and the instrument currency, the conversion runs through an intermediate currency and the 0.5% is charged at each step. |
The two-leg conversion: when 0.5% is charged twice
This is the cost we see least often covered elsewhere, and it is the reason a headline percentage can understate what you actually pay.
XTB applies a 0.5% markup to the mid rate when converting between your account currency and the currency an instrument is priced in. Where a direct rate between the two is quoted, that is one charge of 0.5%. Where no direct rate is quoted, the conversion is routed through an intermediate currency — and the 0.5% is applied at each step.
A two-leg conversion therefore costs 0.5% twice, not 0.5%. On a round trip in and out of the position, an investor in that situation can pay the markup four times over the life of the trade.
The practical defence is the same one that works everywhere else on this page: hold the account in a currency for which a direct pair to your target instrument exists, and reduce the number of conversions you make.
Brokers that avoid the question rather than pricing it well
Three widely used platforms are deliberately left out of the ranked table. Not because they are bad, but because none of them publishes a figure that can be compared with the six above. Ranking them would mean inventing a number.
Trade Republic does publish its conversion margins — but as absolute amounts in the quoted currency rather than as a rate. The USD margin is 0.0014, GBP 0.0011, CHF 0.0014. Those cannot be lined up against a percentage without knowing the prevailing rate, which is why you will see them misreported as percentages elsewhere.
The stated scope is the conversion of foreign-currency income. Whether a margin applies to purchasing a non-EUR asset is not stated in the schedule we read, so we make no claim either way. The practical position: a EUR-instrument portfolio has little exposure to this, a dividend-paying foreign portfolio does.
Scalable’s binding terms and conditions contain a clause governing the exchange rate applied to foreign-currency transactions. A currency markup therefore exists. Its size is not published on any Scalable page we have read.
Separately, Scalable’s own material describes routing euro-denominated trading to domestic and international venues so that no conversion arises on the trade. That is a claim about venue selection, and a correct one — but it is not the same as a claim that no conversion charge exists. Any turnover arriving in a foreign currency, such as a dividend or a coupon, is converted under that clause. Treat “Scalable has no FX fee” as unverified.
On eToro the question is structural rather than per-trade: the trading account is denominated in USD, so deposits in another currency are converted on the way in. Conversion between a local-currency account and USD is stated at 0.75% for the UK and Europe. That is a different shape of cost from the brokers above and does not belong in the same ranked column. Widely circulated figures of 1.5% for eToro conversion appear in none of eToro’s own documents that we have read.
If your portfolio is built entirely from EUR-denominated UCITS ETFs, none of this applies to you at the broker level. There is no conversion, so there is no markup and no minimum. Cheapest FX is no FX, and for a long-term European index investor that is usually the right answer. Broker selection then turns on execution cost, custody, recurring investing and reporting — see our best broker for UCITS ETFs guide.
USD investing is not one thing: US stocks, US ETFs, and UCITS ETFs
The FX question changes depending on which type of asset you are actually buying. These three categories carry different rules, access restrictions and conversion implications.
US shares are ordinary stocks and do not fall under the same retail distribution restrictions as investment funds. Most European brokers can offer them. Conversion applies on each transaction unless you hold a USD balance or the broker lets you trade in your account currency.
US dividends are subject to withholding tax, commonly reduced for eligible residents by filing a W-8BEN. Confirm your broker holds a current one for you.
Under the PRIIPs regime, products distributed to EU and UK retail investors require a Key Information Document. Most US ETF providers have not produced compliant documentation, so brokers cannot offer these products to retail clients. This is a constraint of the regulatory regime rather than a choice made by any individual broker. Existing holders may be able to keep a position without being able to add to it.
UCITS ETFs listed on European exchanges and priced in EUR track the same underlying indices as their US counterparts. No PRIIPs blocker, and no conversion needed at the broker level. Same market exposure, compliant wrapper, simpler workflow. Full comparison in our UCITS vs US ETFs guide.
Buying US individual stocks, or needing USD for any other reason, is what makes the break-even on this page relevant to you. Building a long-term portfolio exclusively through EUR-denominated UCITS ETFs means the conversion question at the broker level mostly disappears, and broker selection shifts to other criteria entirely.
Choose your path in 4 steps
FX optimisation is a decision, not a research project. Four steps get you to the right setup.
If you are EU retail and buying broad index exposure, EUR-denominated UCITS ETFs cover it and no conversion arises. If you genuinely need foreign-currency assets — US individual stocks, or specific instruments with no EUR line — continue to step 2.
This is the step most guides skip. Under about 1,300 per conversion, a percentage broker with no minimum is cheaper — Trading 212 at 0.15% leads that group. Above it, a flat per-order minimum is cheaper and the gap widens with size — IBKR at USD 2.00 per spot order leads there. If you want separate currency balances without IBKR’s platform depth, Lightyear offers them at 0.35%.
Fewer, larger conversions beat monthly micro-conversions under both pricing models — and they move you up the break-even table towards the flat-fee side. Convert quarterly or semi-annually into a foreign-currency balance and buy from that balance. Let foreign-currency dividends accumulate there rather than converting them back each time.
Consistency beats optimisation here. The gain from a well-timed conversion is trivial next to the cost of sitting in cash waiting for one. Convert on a schedule, not on a feeling.
Who fits which path
| Your situation | Best default | Reason |
|---|---|---|
| Converting a few hundred at a time, monthly | Trading 212 | 0.15% with no per-order minimum, and dividends exempt. A flat-fee broker would charge you an effective 0.4% at this size |
| Converting four figures or more, quarterly | Interactive Brokers | USD 2.00 per spot FX order stops scaling with the amount, and separate currency balances mean you convert once and buy many times |
| Wants multi-currency balances without IBKR’s depth | Lightyear | Separate currency balances and explicit conversion at 0.35% on the EU entity — more per conversion than the two above, simpler to operate |
| Wants a clear published rate and broad market access | Saxo or DEGIRO | Both at 0.25%. Saxo verified on the Dutch, Belgian and French schedules; DEGIRO’s AutoFX is embedded in the trade price rather than billed separately |
| Buying EUR-denominated UCITS ETFs only | No conversion at all | Cheapest FX is no FX. Choose on execution cost, custody, recurring investing and reporting instead — FX efficiency is not your constraint |
| Account currency with no direct pair to your instrument | Check for two-leg routing before you commit | Where no direct rate is quoted, a markup can apply at each leg. This is the single largest avoidable conversion cost on this page |
All six, in the order this page ranks them
No reordering for commercial reasons. Trading 212 is first because it wins below the break-even, IBKR second because it wins above it, and XTB last because 0.5% is the most expensive rate here. Check the current schedule on the broker’s own site before funding — rates move and we do not control them.

Frequently asked questions
Which European broker has the cheapest EUR to USD conversion?
It depends on how much you convert at once, which is why a single answer is misleading. Trading 212 charges 0.15% with no minimum, so it stays cheap on small amounts. Interactive Brokers charges a spot FX order from 0.20 basis points with a minimum of USD 2.00 per order, and at retail sizes that minimum is what you actually pay. Below roughly 1,300 per conversion the percentage is cheaper; above it the flat minimum is, and the advantage grows from there. Saxo and DEGIRO sit at 0.25%, Lightyear at 0.35% on its EU entity, and XTB at 0.5%.
Is IBKR always the cheapest FX option for Europeans?
No, and this is the most common error in FX comparisons. IBKR’s spot FX order carries a minimum of USD 2.00 per order. On a 500 conversion that minimum works out at 0.40% of the amount converted, which is worse than every percentage broker in our table. IBKR’s separate automatic conversion mechanism costs 3 basis points of trade value instead, which is a different price for a different action — the two are frequently merged into one figure, and merging them destroys the point. IBKR becomes the cheapest option once your conversions are large enough for the minimum to shrink as a share of the amount, and from that point on nothing here beats it. Pricing can also vary by entity and country, so verify the schedule for the entity that serves you.
Why does FX matter more than commissions for European investors?
Because conversion recurs. A commission is charged on a trade; a conversion charge is levied every time money crosses currencies, which for a monthly investor into foreign-currency assets means every deposit, and on some platforms every dividend and every rebalance as well. A markup of 0.5% applied repeatedly for decades compounds into a cost no commission saving offsets. Zero-commission brokers often recover their economics through exactly this mechanism, which is why the fee schedule is worth reading past the headline.
If I buy UCITS ETFs in EUR, do I still have an FX problem?
Not from the deposit-and-buy workflow. EUR-denominated UCITS ETFs let you skip conversion at the broker entirely. Currency exposure to USD still exists inside the fund — a MSCI World ETF holds USD-denominated stocks whatever currency its shares trade in — but that is fundamental portfolio exposure, not workflow FX drag. You do not pay a spread on the internal exposure. You only pay a spread when you convert at the broker level.
Should I try to time the best EUR to USD conversion rate?
No. Consistency beats optimisation for long-term investors. The practical win is reducing leakage per conversion and converting less often, not guessing short-term currency moves. Investors who wait for a better rate tend to stay in cash longer than they intended, which is usually a far larger cost than a slightly worse conversion.
Does a EUR-denominated ETF remove my currency risk?
No, and this is one of the most common confusions in European investing. A EUR-listed UCITS ETF removes broker-level conversion cost at the point of purchase. It does not remove the currency exposure of the assets inside the fund. A MSCI World UCITS ETF traded in EUR still holds a large majority of its assets in USD-denominated stocks. If EUR strengthens against USD, your portfolio value in EUR terms falls even with flat markets in USD. That is currency exposure, not a fee. It is not necessarily bad — it is simply a different thing from the broker’s conversion markup, and worth not confusing with it.
Can FX fees apply when I rebalance my portfolio?
On platforms that convert automatically, yes. Sell a foreign-currency position into a EUR-only balance and the proceeds convert at the broker’s rate; buy a foreign-currency asset afterwards and they convert again. Both legs are charged. Where you can hold separate currency balances, you can trade between assets in the same currency without triggering either leg. One specific case worth knowing: Trading 212 holds Pie cash in the account’s primary currency, and conversions into and out of a Pie are charged at 0.15%, including dividend reinvestments inside one — so automated portfolio tools can carry conversion costs that manual trading in the same instruments would not.
Is it safe to use Wise or Revolut to convert EUR to USD before funding my broker?
It can work, under specific conditions. The broker must accept deposits in that currency, support the funding route for your country, require the account to be in your own name, and not charge incoming transfer fees that offset the saving. International transfers can pass through intermediary banks that deduct amounts not disclosed to you in advance, and some brokers reject deposits in an unsupported currency outright. Before attempting this route, read the broker’s own funding documentation. Do not assume it works.
Is the cheapest FX broker always the best broker for me?
Not necessarily. If you invest exclusively in EUR-denominated UCITS ETFs, broker-level FX efficiency may be almost irrelevant to your actual costs. The decision then shifts to ETF catalogue, recurring investing features, tax reporting quality, platform reliability and investor protection. FX efficiency matters most when you genuinely need to buy non-EUR assets repeatedly over time. For a long-term UCITS-in-EUR investor, “cheapest FX broker” may not be the right question at all.
Why can I buy US stocks but not US ETFs as a European investor?
US individual stocks are ordinary shares and are not subject to the same EU retail distribution rules as investment funds. US-domiciled ETFs such as SPY or VTI fall under the PRIIPs regime, which requires a standardised Key Information Document before a product can be distributed to EU or UK retail investors. Most US ETF providers have not produced compliant documentation, so brokers cannot offer them to retail clients in Europe. This is a feature of the regulatory regime rather than a decision by any broker. The practical result is that European retail investors build long-term portfolios with UCITS ETFs instead, tracking the same indices.
