Money market ETF vs term deposit: compare €10,000 after costs
Compare capital protection, access to your money and the net return under different interest-rate paths.
A fixed deposit provides an agreed rate for a term; an overnight ETF offers a changing investment return through a broker. Compare protection, withdrawal timing and the net amount left after tax and all costs.
Compare your returns
Change the starting assumptions to compare what each option would leave you after tax, costs and inflation.
Use an annual equivalent return for each option. Enter ETF returns after ongoing fund charges and put commissions and spreads in total costs. Use the effective tax rate for each option in your tax residence.
Term deposit leaves €28.75 more after tax and costs at these assumptions.
This illustration compounds annual returns and inflation over the selected period. It applies tax to positive gains at the end, before subtracting the total costs entered above.
A cash ETF and a fixed-term deposit solve different problems
A fixed-rate term deposit lets you agree an interest rate for a defined period, subject to the bank’s terms. A euro overnight ETF gives you investment exposure whose return changes with short-term rates, with access through a brokerage account. The choice depends on when you need the money, the protection you require and the amount left after costs and tax.
This guide focuses on euro overnight-rate ETFs such as XEON and CSH2. A short-duration bond ETF is a different exposure and can react differently to market changes. Also check the legal product behind a broker’s “cash” offer: it may be a bank deposit, a fund investment or a combination.
| Question | Euro overnight ETF | Eligible bank term deposit |
|---|---|---|
| What do you hold? | Shares in an investment fund | A deposit claim against a bank |
| Is the future return fixed? | No; it varies with the fund and rate path | The agreed fixed rate applies under the contract |
| Deposit guarantee? | No bank deposit guarantee | EU protection generally up to €100,000 per person, per bank |
| Access | Sell on an exchange; execution and settlement apply | Depends on maturity and early-withdrawal conditions |
| Extra costs | Fund costs, dealing spread and possible broker/custody/FX fees | Check account fees and any early-exit interest penalty |
| If overnight rates fall | Future accrual generally falls | An existing fixed-rate contract retains its agreed rate to maturity |
| If overnight rates rise | Future accrual can rise | The existing fixed contract does not automatically reprice |
Capital protection and access to your money
EU deposit guarantee rules generally protect eligible deposits up to €100,000 per depositor, per bank. Accounts at the same bank are aggregated; separate brand names do not necessarily mean separate banking licences. Your Europe explains the limit and exceptions. Check the institution and the applicable guarantee scheme before depositing.
An ETF is an investment, so that bank-deposit guarantee does not apply to its shares. The XEON and CSH2 KIDs describe market and counterparty risks. Regulated custody and segregation of assets are useful safeguards, but they do not remove investment losses.
Protection and access are separate questions. Some term deposits do not allow early withdrawal; others forfeit interest. An ETF can normally be sold during exchange hours, but price, execution, settlement and the broker’s withdrawal process still apply. Compare the actual date cash would reach your bank account with the date you need it.
What happens when the ECB changes rates?
Overnight funds respond to the path of short-term rates. The ECB’s €STR reference rate describes overnight borrowing costs; today’s observation does not fix the return for the next year. A recent twelve-month ETF return also includes a past rate environment that may not repeat.
A fixed deposit offers contractual certainty for its term, while the return available on renewal can differ. If rates fall, the existing fixed rate may be attractive; if rates rise, locking in can have an opportunity cost. Those trade-offs do not establish a single winner in advance. Compare the ECB rate history with the modelled expectations in ECB Watch, keeping the distinction between past data, expectations and guaranteed contract terms clear.
What could €10,000 earn after costs and tax?
The following one-year illustration uses a hypothetical 2.75% fixed deposit and three possible ETF returns. It assumes a 25% tax on the positive gain, no deposit account fee, and €10 total ETF dealing costs. ETF returns are already after ongoing fund costs; we do not subtract TER again. Both positions are assumed to be closed after a year, with no extra cash flows.
The 25% is an arbitrary example, not an EU average or a tax rate for your country. For this simplified calculation, dealing costs are not deducted when computing tax. Real tax bases, allowances, withholding, fund rules and the timing of taxation can differ. The scenarios are not forecasts, current product quotes or an estimate for a specific ETF.
| Scenario | Gain before investor tax / dealing | Tax | Dealing | Net gain | Final balance |
|---|---|---|---|---|---|
| Fixed deposit: 2.75% | €275.00 | €68.75 | €0.00 | €206.25 | €10,206.25 |
| ETF return: 1.50% | €150.00 | €37.50 | €10.00 | €102.50 | €10,102.50 |
| ETF return: 2.50% | €250.00 | €62.50 | €10.00 | €177.50 | €10,177.50 |
| ETF return: 3.50% | €350.00 | €87.50 | €10.00 | €252.50 | €10,252.50 |
The deposit produces €206.25 after the assumed tax. At a 2.50% realised fund return, the ETF produces €177.50 after tax and trading costs. Under these exact assumptions, the ETF needs approximately 2.88% after fund costs and before investor tax to match the deposit. That break-even changes when fees, taxes or the holding period change.
The arithmetic is: gain = €10,000 × annual return; tax = positive gain × 25%; net gain = gain − tax − dealing costs. The break-even ETF return is 2.75% + €10 ÷ (€10,000 × 75%). This comparison assumes positive returns; real investment losses are possible and national loss-relief rules are not modelled.
A positive net return can still lose purchasing power
At an assumed 2% annual inflation rate, divide the final balance by 1.02 to express it in starting-year euros. The deposit’s €10,206.25 corresponds to a real return of 0.06%. The 2.50% ETF scenario produces a real return of -0.22%. Inflation here is another hypothetical input, not the latest figure for a country.
The general formula is real return = (final balance ÷ initial balance) ÷ (1 + inflation) − 1. Simply subtracting inflation from the net percentage is an approximation. Use the EuroYields real-yield calculator to explore your own assumptions and check its tax settings against your situation.
Which fits your cash needs?
A fixed deposit is worth comparing when you know the spending date, value contractual interest certainty and can accept the withdrawal terms. An overnight ETF is worth examining when you already use a broker, accept the investment structure and changing return, and have checked the total entry and exit costs. Neither description replaces checking the actual product.
For a short holding period or a small balance, trading costs can consume much of an ETF’s accrual. For money needed immediately, focus on withdrawal timing before chasing a few basis points. It can be reasonable to use different products for immediate bills and money reserved for a known future date.

Common questions about cash ETFs and deposits
Does an accumulating ETF avoid tax?
Accumulation describes the treatment of income inside the fund. It does not determine your country’s taxation of that investment. Check local rules for the share class and account you use.
Can a deposit beat an ETF with a higher advertised rate?
Yes. Compare returns over the same period after all applicable charges and tax. A variable annualised rate and a contractual fixed rate are different quantities.
Is a low-risk ETF equivalent to a guaranteed deposit?
No. An investment risk classification does not create deposit insurance or a guaranteed redemption value.
