Spaarrente vergelijken als zzp’er: 5 rustige checks

A good month can give you a misleading sense of peace of mind. The bills are paid, your VAT is set aside, and you finally have some money left over. Then a photographer, designer, or filmmaker draws a comparison with savings accounts. At the top is a single high percentage. Does that automatically make it the best place for your emergency fund?

Probably not.

If you’re a self-employed professional looking to compare savings account interest rates, you’re comparing more than just a number. The best account depends on what you need the money for. Does it need to cover a late payment tomorrow? Can part of it sit there for a year? And do you want to know which bank you’re helping to finance with your savings?

So “best” is relative. Interest rates matter, but access, protection, terms, and values determine whether an account is truly right for you.

How can you compare savings interest rates without just looking at the percentage?

Suppose you’ve set aside €12,000. €4,000 is for taxes, €5,000 is your emergency fund, and €3,000 is money you probably won’t need for a year. On paper, it’s a single balance. In reality, each portion serves a different purpose.

So start by asking yourself five questions:

1. What is the effective interest rate over a full year?

2. Can the bank change the interest rate during the term?

3. When is the interest paid out, and does it then earn interest on its own?

4. Can you withdraw the money without fees or a waiting period?

5. Under which banking license and deposit insurance system is the money covered?

The advertised interest rate is usually a percentage per year. However, your actual return may vary depending on when you make the deposit, the promotional period, a minimum balance requirement, or conditions for new customers. Therefore, be sure to review the disclosure document and calculate based on the amount and term that actually apply to you.

With €5,000 in savings, a difference of 0.25 percentage points amounts to approximately €12.50 in gross interest per year. That amount can be welcome. But if you have to tie up a buffer you’ll need next month, that extra interest won’t buy you much peace of mind.

When is a flexible savings account a better choice than a time deposit?

A flexible savings account is suitable for money that needs to remain accessible. Think of the videographer who needs to rent a new camera after their equipment breaks down, or the illustrator who’s waiting six weeks for a large invoice. The interest rate is usually variable: the bank can raise or lower it. On the other hand, you can generally access your money quickly.

A time deposit has an agreed-upon term, such as six months, one year, or longer. The interest rate is usually fixed for that period. Early withdrawal may not be possible, may only be allowed in special situations, or may incur fees. The exact rules vary by bank.

That’s why you don’t have to choose between keeping everything flexible or locking everything in. You can divide your savings into layers:

• money for taxes is kept separate and immediately accessible;

• your first few months’ emergency fund is freely accessible;

• only the portion you can demonstrably do without may be placed in one or more time deposits;

• a planned amount for a laptop, studio renovation, or a relaxing summer gets its own maturity date.

Don’t have a personal minimum yet? In the Oddny guide on saving and building a buffer for slow months, you can read how to keep your different savings pots separate. That makes comparing interest rates a lot fairer.

What exactly does the European deposit guarantee protect?

A high interest rate says nothing about the bank’s license. Check that separately.

For banks covered by the Dutch deposit guarantee, funds ranging from 1 cent up to a maximum of €100,000 per person per bank are protected if a bank goes bankrupt. If you have a joint account, the protection applies per account holder. As a result, two account holders can have up to €200,000 protected between them.

Pay special attention to the words “per bank.” Two brand names may fall under the same banking license. In that case, your balances are added together up to the €100,000 limit. DNB maintains a registry for the Dutch deposit guarantee scheme where you can check which banks and brand names are covered by the Dutch system.

If you save with a bank in another EU country, the guarantee scheme of the country where that bank is licensed generally applies. The EU directive stipulates coverage of €100,000 per depositor per bank. Once a competent authority or court has determined that deposits are unavailable, the amount to be reimbursed must be made available within seven business days, according to that directive.

This does not automatically make a foreign EU bank risky or safe. It does mean, however, that before opening an account, you need to know three things: the legal entity of the bank, the country where it is licensed, and the deposit insurance scheme that will make the payout. Keep this information in your records. When turmoil strikes, you don’t want to have to figure out where your account is legally based.

Which terms and fees affect the outcome?

Sometimes the difference lies in a single line at the bottom of the product page. An interior designer sees a 3% interest rate but later discovers that the rate applies only for the first three months. Another account requires a minimum deposit that exceeds the amount that can remain accessible. A time deposit may offer interest over the entire term, but early withdrawals are not permitted.

So be sure to check at least these points before making your choice:

• Is the interest rate fixed, variable, or temporary?

• Does the interest rate apply to the entire balance or only up to a certain limit?

• Is there a minimum or maximum deposit?

• Are opening, maintaining, transferring, or early withdrawals free of charge?

• When does interest accrual begin, and when is it paid out?;

• Is a corresponding account required?

• What happens automatically at the end of a deposit term?

• How quickly is the money available in your checking account again after a withdrawal?

Next, compare the rates in euros. A difference of a few tenths of a percent may be less than a withdrawal fee, missed promotional interest, or the inconvenience of funds not being available. The highest advertised interest rate is only relevant if the terms and conditions are a good fit.

Does the bank behind the interest rate also align with your values?

For a self-employed creator, choosing a bank can also be a source of friction: you carefully select which projects to take on, but you have little insight into what the bank is doing behind the scenes with your account.

Ethical preferences aren’t a universal ranking. One designer may want to avoid fossil fuel financing above all else. A documentary filmmaker might focus on human rights or weapons. Someone else might prioritize local businesses or the energy transition.

Therefore, use a sustainability score as an additional lens, not as a substitute for the financial fundamentals. Ask what the assessment is based on, what year the data comes from, and whether the score applies to the entire banking group. A “green” label without a clear methodology tells you very little. And a high score doesn’t compensate for limited access or a lack of deposit protection.

The choice should remain a matter of balance. Perhaps you’ll accept a slightly lower interest rate at a bank that better aligns with your values. Perhaps you’ll keep your emergency fund in the most accessible account and apply stricter criteria only to your long-term savings. The key is to be aware of the trade-offs you’re making.

How do you make a choice that still works during a quiet month?

Take a quiet half-hour and compare up to three options side by side. For each account, write down the effective interest rate, accessibility, term, banking license, deposit insurance, fees, and ethical assessment. Then, don’t test the best month—test the toughest month.

A freelance art director receives two postponed projects in August. Can that person access the buffer within one business day? A photographer sets aside €4,000 for a lens that will be needed in nine months. Will the deposit mature on time? A creator has savings exceeding €100,000 across two bank brands. Are those savings actually covered by two separate banking licenses?

These questions make the comparison personal. They bring the calculation back to why you’re saving: to buy time, keep your options open, and avoid having to rush to fill every quiet moment.

If you want to explore current options, you can use Oddny Savings to browse savings accounts and time deposits through Raisin. For each option, check the current interest rate, terms and conditions, banking license, and deposit insurance yourself. You don’t have to decide until everything fits.

Comparing savings interest rates isn’t really a race to find the highest number. It’s a way to determine where your money can do its job best. First, decide what you want to protect. The interest rate comes second.
