Interactive Brokers has a reputation for being the serious investor’s broker: cheap, powerful, and a little intimidating. So it surprises people to learn that it will happily run your monthly ETF buys on autopilot, just like a German neobroker’s savings plan. The feature is called Recurring Investments, and once it is set up you can leave a global portfolio to build itself for years while you barely open the app.
I run part of my own money this way. The honest summary is this: IBKR’s automation is not quite as slick as tapping “create Sparplan” on Trade Republic, and the first setup takes ten minutes of clicking. But it is dirt cheap, it works across currencies and dozens of exchanges, and it supports fractional shares so your full contribution gets invested every month with no cash left stranded. If you already keep your ETFs at IBKR, there is no reason to do this manually.
Below I will walk through setting up recurring investments, how funding cadence and base currency interact, and a rebalancing approach that keeps you out of the taxman’s way. If you are still choosing a broker, my longer case for this one is in why Interactive Brokers stands out for ETF investors in Europe. For more detail, see our guide: Interactive Brokers ISA.
What “automating” actually means on Interactive Brokers
Two separate things get bundled under “automation”, and it helps to keep them apart.

The first is automatic buying: putting fresh money to work on a schedule without you placing each order. This is dollar-cost averaging, and IBKR’s Recurring Investments handles it directly. You pick an ETF, an amount, and a frequency, and the system places the order for you on each date.
The second is rebalancing: nudging your holdings back toward target weights as markets drift. IBKR does not have a true one-click “rebalance my whole portfolio to these percentages and place all the trades” button for a normal cash account in the way a robo-advisor does. What it gives you instead is a Rebalance tool in the portfolio view that shows current versus target allocation and lets you generate the orders, plus the option to simply steer new contributions toward whatever is underweight. For most long-term ETF investors the second method is enough and it is more tax-efficient, which I will come back to.
How recurring investments differ from a neobroker Sparplan
If you have used Trade Republic or Scalable Capital, the mental model is the same, with a few differences worth knowing. A neobroker savings plan is essentially free and set up in three taps, but you are locked to that broker’s exchange, its currency (euro), and its fund menu. IBKR’s version costs a small commission per execution, takes a bit more setup, and asks you to understand order routing. In exchange you get access to virtually every UCITS ETF across European exchanges, multi-currency funding, and pricing that stays low even as your contributions grow. I compare the pure savings-plan brokers head to head in best brokers for ETF savings plans in Europe.
| Feature | IBKR Recurring Investments | Neobroker Sparplan (e.g. Trade Republic) |
|---|---|---|
| Cost per execution | Small commission, often around €1–2 (verify current pricing) | Usually free on savings plans |
| Fractional shares | Yes, on eligible ETFs | Yes |
| Fund universe | Vast: most UCITS ETFs across many EU exchanges | Curated list, still thousands of funds |
| Currency flexibility | Multi-currency; hold and fund in EUR, USD, GBP etc. | Euro only for most euro-zone users |
| Setup effort | Moderate: a few screens the first time | Very low |
| Best for | Larger portfolios, multi-currency, exchange control | Simplicity and zero cost |
Setting up a recurring investment, step by step
The exact wording shifts between the mobile app and the desktop client, and IBKR updates its interface regularly, so treat this as the shape of the process rather than pixel-perfect instructions. Confirm each screen against the current version.
Fee figures in this guide are cross-checked against our EU broker fee dataset, reviewed quarterly.
1. Set your base currency and fund the account. In account settings, choose the currency you think in, usually EUR. Then send money by SEPA transfer from your bank. SEPA is free and typically lands the next business day. Fund a little ahead of your recurring date so the cash is sitting there when the order fires.
2. Find the right ETF line. Search the fund by name or ISIN and pick the listing that trades in your base currency on a European exchange such as Xetra or Euronext. Buying the euro line of a fund avoids an unnecessary currency conversion. If you deliberately want the USD line, IBKR’s conversion cost is tiny, but for a clean euro portfolio the euro listing keeps things simple. My full buying walkthrough for two core funds is in how to buy VWRA and IWDA on IBKR as a European.
3. Open Recurring Investments and create a plan. On the fund’s page, choose the recurring or “invest on a schedule” option. Enter a fixed amount, say €500, and a frequency such as monthly. Because fractional shares are supported on eligible ETFs, the whole amount gets invested rather than leaving change behind.
4. Match the schedule to your funding. Set the recurring date a day or two after your salary or SEPA transfer clears. If the cash is not present, the order can be skipped, so a small buffer avoids missed months.
5. Confirm pricing and review. Use Tiered pricing, which is cheapest for most European ETF trades, and check the commission estimate. Then let it run. You will get confirmations after each execution, and you can pause or edit the plan any time.
A rebalancing approach that avoids unnecessary tax
Rebalancing sounds like it demands selling your winners, and selling can trigger capital-gains tax in many European countries. There is a gentler method that suits an accumulating investor.
Rebalance with new money first. Each month, direct your fresh contribution toward whichever holding has fallen below its target weight. If your equity sleeve has run ahead and your bond sleeve has lagged, buy more of the bond ETF that month. Over a year of contributions this quietly pulls the portfolio back toward target without a single sale, which means no realised gains and no tax event. For a two or three fund portfolio this is usually all you ever need.

Use threshold rebalancing for the rest. Only when an allocation drifts a long way, say more than five percentage points from target and contributions alone cannot fix it, do you actually sell. IBKR’s Rebalance tool lets you enter target percentages and it calculates the trades. Do this sparingly, and check the tax consequences in your country before you sell. If you want to eyeball your weights and overlaps first, our free UCITS ETF comparison tool is a quick way to sanity-check what you actually hold.
Where this leaves your money’s safety
Automating buys does not change how your assets are held. Your ETFs sit in segregated custody and your cash is covered by the applicable investor-compensation rules, which I explain in Interactive Brokers Europe (IBIE) investor protection. Automation is just a scheduler placing orders you would otherwise place by hand. It carries no extra counterparty risk, and you can switch it off at any moment. For more detail, see our guide: Interactive Brokers vs Trading 212 for ETF Investors.
Is automating on Interactive Brokers worth it? My verdict
If you already custody your ETFs at Interactive Brokers, turn on Recurring Investments today. There is no good reason to place the same monthly order manually when the platform will do it for a euro or two and invest fractionally so nothing sits idle. The multi-currency support and enormous fund range make it especially strong for larger or more complex portfolios.
If you are a beginner with a simple one or two fund plan and you value zero fees and three-tap setup above all else, a neobroker savings plan is the softer landing, and that is a perfectly good choice. But for anyone who wants low costs to stay low as the balance grows, or who invests across currencies, IBKR’s automation is the quiet workhorse I keep coming back to. Pair it with contribution-led rebalancing and you have a portfolio that largely runs itself. You can read IBKR’s own description of the feature on the Interactive Brokers Recurring Investments page.
Frequently asked questions
Q: Does Interactive Brokers have automatic ETF investing like a savings plan?
A: Yes. The feature is called Recurring Investments and it lets you buy a chosen ETF for a fixed amount on a set schedule, such as monthly. It supports fractional shares on eligible funds, so your entire contribution is invested each cycle rather than leaving cash behind.
Q: How much does a recurring investment cost on IBKR?
A: You pay IBKR’s normal commission per execution, which for a typical European ETF trade under Tiered pricing is often around one to two euros. That is more than a free neobroker savings plan but still very low, and it stays low as your contributions grow. Always verify the current pricing on IBKR’s own fee schedule before relying on a figure.
Q: Can I automatically rebalance my whole portfolio on Interactive Brokers?
A: Not with a single robo-style button for a standard cash account. IBKR offers a Rebalance tool that shows current versus target weights and generates the trades, but the most tax-friendly approach is to steer each new monthly contribution toward whatever is underweight, so you rarely need to sell.
Q: Does automating my buys reduce the tax I owe?
A: Automation itself is tax-neutral; it just places orders. What can save tax is rebalancing with new money instead of selling, because you avoid realising capital gains. Accumulating ETFs may still face country-specific rules such as Germany’s Vorabpauschale, so check how your residence treats them and consider a local tax adviser.
Q: Which currency should I use for automatic ETF buys on IBKR?
A: For a euro-based investor, fund in euro and choose the euro-denominated listing of your ETF on an exchange like Xetra or Euronext to avoid a currency conversion on every purchase. IBKR’s conversion fee is among the cheapest available if you do need to hold or buy in another currency, but matching your account currency keeps the setup simplest.
Q: What happens if there is not enough cash on my recurring investment date?
A: The scheduled order may be skipped for that cycle rather than going into debt or borrowing on margin unexpectedly. To avoid missed months, set the recurring date a day or two after your SEPA transfer or salary normally arrives, and keep a small cash buffer in the account.
