If you are paying a robo-advisor to run your portfolio and quietly wondering whether you could just do it yourself, you have already spotted the thing that matters: the fee. Most robo-advisors in Europe charge somewhere between 0.25% and 1% a year on top of the funds they hold, and the portfolio underneath is usually a handful of index ETFs you could buy in an afternoon. Replicate it yourself and your all-in cost can drop to roughly 0.2%. Over thirty years, that gap is not small change. It is a meaningful slice of your final pot.
So the honest answer to “should I leave?” is: for most people with a simple, long-horizon portfolio, yes, going DIY saves real money and the mechanics are easier than the marketing suggests. But it is not automatic. A robo earns its fee if it is the only reason you stay invested through a crash, and the exit itself can trigger a tax bill that eats years of savings if you handle it carelessly. This article is about doing the maths properly and then deciding: sell, transfer, or stay.
I have run my own ETF portfolio for over eleven years, so I am biased towards DIY. I will try to be fair to the case for staying, because for some readers it is the right call.

There are two layers of cost, and the marketing tends to show you only one. The headline is the management fee, the “0.25% a year” or “0.75% a year” the robo advertises. Underneath sits the cost of the ETFs the robo puts you in, the ongoing charge (TER) of each fund, which is separate and which you also pay. Add them together and a “cheap” robo at 0.5% management plus 0.2% fund costs is really costing you around 0.7% a year. A managed product at the pricier end can quietly total more than 1%.
Put a number on it. On a €100,000 portfolio, 0.7% is €700 a year against maybe €200 for a self-run version. The €500 difference does not sound dramatic in year one. The problem is compounding: that fee is skimmed every year from a growing balance, and the money it removes never gets to compound for you. Europe’s markets regulator publishes an annual report on the costs and performance of retail investment products, and its consistent finding is that ongoing charges are the single biggest predictable drag on long-run net returns. You can read the summaries on the ESMA website. Fees are the one variable you fully control, which is exactly why they are worth this much attention. I walk through the same maths on a larger scale in my piece on using a wealth manager versus DIY ETFs.
What a robo genuinely does for you
Before you cancel anything, be honest about what you would be giving up, because it is not nothing.
A decent robo automates the whole loop. It picks a risk-appropriate allocation, drips your monthly contribution in without you thinking about it, and rebalances back to target when markets drift. Some run tax-loss harvesting on your behalf, which has real value in taxable accounts. And there is the least glamorous benefit of all: it stops you fiddling. A one-screen app with no “sell” button screaming at you during a 30% drawdown has kept plenty of people invested who would otherwise have panicked out at the bottom. If that describes you, the fee might be the cheapest insurance you ever buy.
The question is whether you need someone else to supply that discipline, or can build it into a far cheaper DIY setup.
What going DIY actually involves
Less than most people fear. The robo’s clever-sounding allocation is usually reproducible with one or two funds. A single global all-world ETF gives you thousands of companies across developed and emerging markets in one line. Add a bond or cash buffer sized to your timeline and you have covered what a mainstream robo is doing. If you are new to the building blocks, my beginner’s guide to ETFs covers the ground, and the UCITS ETF comparison tool lets you line up costs and size side by side.
The automation the robo sold you is available for free at most modern brokers. You set up a savings plan (a Sparplan, an AutoInvest, a recurring order) that buys the same ETF every month on the same day. Rebalancing, for a one or two fund portfolio, mostly takes care of itself: you simply direct new contributions towards whichever holding has fallen behind. You might do a deliberate rebalance once a year in ten minutes. That is the entire job. The hard part was never the mechanics; it was deciding to keep it simple and then leaving it alone.
Robo-advisor versus DIY ETF portfolio
| Feature | Robo-advisor | DIY ETF portfolio |
|---|---|---|
| All-in annual cost | ~0.5%–1%+ (management + fund TER) | ~0.15%–0.25% (fund TER only) |
| Rebalancing | Automatic | Manual, or via new contributions |
| Setup effort | Minimal, one questionnaire | An afternoon to learn, then automated |
| Discipline / hand-holding | Built in, harder to meddle | You supply it |
| Portfolio control | Limited to their models | Full, you choose every fund |
| Ease of leaving | Often sell-only (see below) | Standard ETFs, usually transferable |

The exit problem: can you transfer, or must you sell?
This is the part that catches people out, and it is worth understanding before you press anything. The clean way to move brokers is an in-specie transfer, where the actual fund units move to your new account without being sold, so you never realise a gain and never trigger tax. It works beautifully for plain, widely held ETFs.
The trouble is that many robo-advisors do not put you in plain, widely held ETFs. They put you in their own model portfolio, sometimes built from proprietary or white-labelled funds that no other broker will accept. When that is the case, an in-specie transfer is simply not possible: to leave, you have to sell, withdraw the cash, and rebuy at the new broker. In a taxable account, selling means realising whatever gains have built up, and that can mean a capital-gains tax bill.
If you are sitting on large gains
Do not let the fee saving stampede you into a needless tax event. Run the numbers: the tax you would pay on selling now, against the extra fees you would keep paying by staying. If the gains are big and your horizon is long, it can be worth spreading the exit across two tax years to use two years of allowances, or pairing a winning sale with a loss elsewhere to offset it. Where the holdings can transfer, always prefer the transfer. The general approach mirrors what I set out in the playbook for moving bank funds into ETFs. Tax mechanics differ by country and change, so confirm your own position with the local tax authority or an adviser before you sell anything large.
My verdict: what I would do
If your robo holds ordinary index ETFs and charges a fat management fee, leave. Ask first whether you can transfer the holdings in-specie to a low-cost broker; if yes, that is the cleanest move and there is little reason to hesitate. Pick a home from the European broker hub, set up a savings plan into one all-world ETF, and pocket the fee difference for the rest of your investing life.
If the robo locks you into proprietary funds and you have large unrealised gains, slow down. Calculate the tax cost of exiting versus the fees saved, and if the tax hit is heavy, phase the sale over tax years rather than doing it in one go. Sometimes the maths says wait.
And if the honest truth is that the robo is the only thing keeping you invested when markets fall, and the fee is modest, staying is a perfectly rational choice. A slightly more expensive portfolio you actually hold beats a cheaper one you bail out of. Only you know which of these is really you.
Frequently asked questions
Q: How much does a robo-advisor really cost compared with DIY?
A: A typical robo charges roughly 0.25%–1% a year in management fees, plus the TER of the ETFs it holds, so the all-in figure is often around 0.5%–1%. A self-run one or two fund portfolio usually costs about 0.15%–0.25% all-in. On a large balance over decades, that gap compounds into a substantial sum, because the fee is skimmed from a growing pot every year.
Q: Can I transfer my robo-advisor portfolio to a new broker without selling?
A: Sometimes. If the robo holds standard, widely available ETFs, an in-specie transfer can move the units without a sale or a tax event. Many robos, however, use their own model or proprietary funds that other brokers will not accept, in which case you must sell and rebuy. Ask your provider directly whether an in-specie transfer out is supported before you plan the move.
Q: Will leaving my robo-advisor trigger a tax bill?
A: Only if you have to sell holdings in a taxable account and those holdings are sitting on a gain. An in-specie transfer avoids this because nothing is sold. If you must sell, you realise the gain and may owe capital-gains tax, so it can pay to spread the sale across tax years or offset it against losses. Tax rules vary by country, so verify your position locally.
Q: Is DIY ETF investing hard to manage?
A: For a simple portfolio, no. One global all-world ETF plus an optional bond or cash buffer covers most people’s needs, and a broker savings plan automates the monthly buying for free. Rebalancing a one or two fund portfolio is largely handled by directing new contributions, with maybe a ten-minute check once a year. The discipline to leave it alone matters more than any technical skill.
Q: What does a robo-advisor do that I would have to replace myself?
A: Mainly automatic rebalancing, automated contributions, and, in some cases, tax-loss harvesting, plus the behavioural benefit of a simple app that discourages meddling. Automated contributions and basic rebalancing are available free at most brokers via savings plans. The one thing you must supply yourself is the discipline to stay invested through downturns.
Q: Should I ever stay with my robo-advisor?
A: Yes, in two cases. If exiting would trigger a large tax bill that outweighs years of fee savings, staying or phasing the exit can be the better maths. And if the robo is genuinely the reason you remain invested during market falls and its fee is modest, that discipline can be worth paying for. A portfolio you hold through a crash beats a cheaper one you abandon.
