Automation removes the biggest risk in index investing: yourself
Passive investing is simple in theory — buy a low-cost UCITS ETF monthly, hold for decades, don’t panic-sell. In practice, the human element is the largest source of underperformance. Investors skip months during downturns, delay starting because the market “looks expensive,” and make impulsive changes after short-term volatility.
- Consistency — you invest every month regardless of market conditions
- Time in market — capital is deployed promptly, not left in cash
- No willpower required — investing becomes a background process
- Habit formation — treating investment as a fixed expense, not discretionary
Research shows lump-sum investing outperforms DCA in rising markets roughly two-thirds of the time — more capital earns returns for longer. Regular automated investing is not a performance strategy. It is a behavioural one. For most people investing from regular income, the real alternative to monthly automation isn’t a smarter lump sum — it’s procrastination.
Automation features by broker
Four brokers cover the realistic options for European investors. Here’s how they compare on the features that matter for regular automated investing.
| Broker | Feature | Min. | Fractional | Commission |
|---|---|---|---|---|
| Trade Republic | Savings plans (Sparpläne) | €1 | Yes | Free |
| Trading 212 | Pies + AutoInvest | €1 | Yes | Free |
| IBKR | Recurring Investments | ~€1 | Limited | Standard fees |
| DEGIRO | None (manual only) | Full shares | No | Free (core, 1x/mo) |
Trade Republic: the simplest savings plan in Europe
Trade Republic is the most accessible automated ETF investing option for European retail investors — minimum €1, commission-free, fractional shares, clean mobile setup.
- Search for an ETF and select “Create savings plan”
- Choose an amount — minimum €1, no maximum
- Choose a frequency: weekly, biweekly, monthly, or quarterly
- Choose a date — ideally a few days after your salary arrives
- Trade Republic buys the ETF automatically on that date, including fractional shares
- Commission-free on all savings plans
- €1 minimum — works for any budget
- Fractional shares — full amount always deployed
- Wide UCITS ETF catalogue (VWCE, CSPX, IWDA, and more)
- Interest on uninvested cash
- Mobile app only — no desktop platform
- Executes at a single daily price, not live market price
- One savings plan per ETF — multi-asset automation requires multiple plans
- Not ideal for large contributions where execution precision matters
Trading 212 Pies: multi-ETF automation with custom allocations
Pies are the most flexible multi-ETF automation tool available to European retail investors. You define a target allocation across up to 50 instruments, set a recurring deposit, and the broker handles the rest.
You define a Pie: which ETFs to include and a target percentage allocation for each (must sum to 100%). You then set an AutoInvest plan — weekly, biweekly, or monthly — at a fixed deposit amount. When it runs, Trading 212 buys fractional shares of each holding to move actual allocations toward your targets. If one position has drifted above its target, new money goes to underweight positions — automatic drift correction on every contribution.
Example: 80% VWCE + 20% AGGH, €200/month AutoInvest. Each month: €160 toward VWCE, €40 toward AGGH — adjusted for drift. Zero manual orders.
- Multi-ETF Pies with custom target allocations
- Drift correction on every contribution
- Fractional shares — full deployment guaranteed
- Commission-free on ETFs
- Both mobile and desktop access
- Pies can encourage over-complexity — a 2-ETF Pie works as well as a 10-ETF one
- AutoInvest executes at live market prices — slightly less predictable than a fixed plan price
- FX drag applies when buying non-EUR assets repeatedly
- Shorter track record than DEGIRO or IBKR
Interactive Brokers: recurring investments for larger portfolios
IBKR is the preferred broker for larger European portfolios. Its automation features are functional but not its headline strength — the real reasons to use IBKR are cash interest, multi-currency handling, and market breadth.
Via Client Portal → Recurring Investments: select a security, specify a fixed amount or number of shares, choose weekly/biweekly/monthly. IBKR places a market order on your chosen schedule. Standard IBKR commissions apply — as low as €1.25 per trade on European exchanges under the tiered model, which is reasonable for contributions of €500 or more.
Note: fractional shares for EU-listed ETFs are more limited than on Trade Republic or Trading 212. The EU Lite (commission-free) tier is not available to EU-resident investors.
IBKR’s recurring feature is best for investors already using IBKR as their primary broker — for its superior cash interest rates, multi-currency accounts (deposit EUR, convert once, hold USD), or broader market access — who want to add systematic contributions on top of an existing portfolio. If your only goal is simple monthly ETF automation from scratch, Trade Republic or Trading 212 are easier starting points.
DEGIRO: no automation, but a workable manual approach
DEGIRO has no native savings plan. All investing is manual — but with discipline and the core selection programme, it can still be very low cost.
- Set a fixed “invest day” each month — e.g. the 5th
- On that date, log in and place your ETF order
- Use a core selection ETF — one free trade per month per ETF
- Batch contributions — one larger monthly purchase is more efficient than multiple small ones
- You invest €500+/month where the manual routine is straightforward
- You want a well-established Dutch broker with a long track record
- You are already using DEGIRO and want to consolidate
- You prefer to choose your own execution timing
- No fractional shares — small contributions leave idle cash
- No automation — requires willpower and calendar discipline every month
- No interest on uninvested cash
- One free trade limit means a second purchase of the same ETF incurs fees
Which broker fits your situation?
- You want the simplest possible setup — one ETF, one plan, done
- You invest €50–€500/month and want full fractional deployment
- Mobile-first investing suits your workflow
- You want to earn interest on idle cash between contributions
- You want to automate a multi-ETF portfolio with a custom split
- You want automatic drift correction on each contribution
- You like both mobile and desktop access
- You invest €50–€1,000/month with full deployment
- You already use IBKR and want to add systematic contributions
- You invest €1,000+/month where IBKR’s low per-trade cost is competitive
- Multi-currency portfolio management matters
- Best available cash interest rate is a priority
- You already hold your portfolio at DEGIRO and want to consolidate
- Larger monthly amounts where the manual routine is simple
- You prefer to control execution timing yourself
- Your target ETF is on the core selection list
Five steps to a fully automated investment system
Regardless of which broker you choose, the setup logic is the same. Follow these steps once, then leave it alone.
A one- or two-ETF portfolio is easier to automate, cheaper to run, and no less effective than a complex 10-fund allocation. A global equity ETF (VWCE, IWDA + EMIM, or similar) covers most of what you need. Add a bond ETF only if you have a specific reason.
Treat your monthly investment as a fixed expense, not a discretionary saving. Start with whatever you can commit to consistently rather than an aspirational figure you’ll struggle to maintain in a downturn.
On Trade Republic or Trading 212 this takes under five minutes — select the ETF, set the amount and date, confirm. On IBKR, go to Client Portal → Recurring Investments. Set the execution date a few days after your expected salary date to ensure the transfer clears first.
Set up a standing order from your bank account to your brokerage for the day after your salary arrives. Bank transfer on day 1, savings plan executes on day 3 — fully hands-off with no manual action required month to month.
Once your automation runs, resist the urge to adjust it frequently. Review allocation and contribution amount once a year — when income changes, after a major life event, or when deliberately rebalancing. Frequent tinkering is one of the main ways investors undermine systematic strategies.
Open your account and start automating
Choose based on what you need: simplicity (Trade Republic), multi-ETF flexibility (Trading 212), market breadth (IBKR), or lowest cost on larger manual contributions (DEGIRO).

Frequently asked questions
Can you automate ETF investing in Europe?
Yes. Trade Republic offers commission-free savings plans from €1 with fractional shares. Trading 212 Pies automate a multi-ETF portfolio with custom allocations and AutoInvest. Interactive Brokers has a recurring investment feature suited to larger accounts. DEGIRO has no native automation — all investing is manual.
What is a savings plan (Sparplan) for ETFs?
A savings plan automatically invests a fixed euro amount into a chosen ETF on a regular schedule — typically monthly. You set the ETF, amount, and date; the broker handles the purchase including fractional shares where the amount is less than one full share. This implements dollar-cost averaging without requiring any manual action each month.
How do Trading 212 Pies work?
A Pie is a basket of up to 50 ETFs or stocks with defined target percentage allocations. You set an AutoInvest schedule (weekly, biweekly, or monthly) and a fixed deposit amount. When it runs, Trading 212 buys fractional shares of each holding to bring allocations toward your targets — automatically correcting for drift on each contribution. Commission is zero.
Does Trade Republic offer automated ETF investing?
Yes. Trade Republic savings plans invest a fixed amount — from €1 — into a chosen ETF at your chosen frequency: weekly, biweekly, monthly, or quarterly. Plans are commission-free and fully support fractional shares, so the full amount is always deployed. Trade Republic is one of the most popular automated investing platforms in continental Europe.
Can I automate investing with Interactive Brokers?
Yes, via Recurring Investments in Client Portal. You set a security, fixed amount, and frequency; IBKR places the order automatically. However, fractional share support for EU ETFs is more limited than on Trade Republic or Trading 212, and standard IBKR commissions apply. The feature works best for investors already using IBKR for a larger portfolio who want to add systematic contributions on top — for contributions of €500 or more the per-trade cost is proportionally reasonable.
Does DEGIRO offer automated investing or savings plans?
No. DEGIRO has no native savings plan or automation feature. All investing is manual. However, the core selection programme offers one free trade per month per ETF, making a disciplined manual monthly purchase very low cost. Investors using DEGIRO need to impose their own calendar discipline — set a fixed invest day and treat it as a non-negotiable routine.
Is automated ETF investing the same as dollar-cost averaging?
In practice, yes. Regular automated investing deploys a fixed amount at consistent intervals — the definition of DCA. Research shows lump-sum investing outperforms DCA in rising markets most of the time. The real value of automation is behavioural: it prevents market timing, enforces consistency, and turns investing into a background process rather than a decision that can be deferred.
What is the best broker for automated ETF investing in Europe?
For most European investors starting with automated monthly investing, Trade Republic (simplest savings plans, commission-free, fractional shares) or Trading 212 (multi-ETF Pies with drift correction) are the strongest choices. IBKR suits larger portfolios where cash interest and execution quality matter more. DEGIRO works for disciplined manual investors willing to invest manually on a fixed schedule each month.
