Minimum payment or fixed instalment: what paying little costs

If you pay a percentage of what you owe, the payment falls along with the debt and the time stretches out a lot. In the example, €2,000 at 18% TIN paid at 3% of the balance, with a €25 minimum, takes 103 months and costs €1,463 in interest; at a fixed €60, 47 months and €793.

What is a revolving card’s minimum payment?

It’s the least the contract lets you pay each month. Each issuer works it out its own way, almost always as a percentage with a minimum in euros.

Some examples, from each issuer’s documents or Asufin’s 2025 survey:

Card Minimum payment
WiZink cards (terms from January 2026) The higher of €40 and 2.5% of the money used plus the month’s interest, fees and insurance
Cetelem credit card 3.70% of the most you’ve ever owed, or €9 if that’s less
Visa & Go, from CaixaBank 1.5% of the debt, per Asufin
Bankintercard Platinum 2.5%, with an €18 minimum, per Asufin

Banco de España warns that with a small payment you may not even cover the month’s interest, and the debt can grow.

What’s the difference between paying a percentage and a fixed instalment?

With a percentage of what you owe, the payment falls as the debt falls, so each month you pay off less. With a fixed instalment you pay the same each month, and a growing share of it goes to the debt.

In the example of €2,000 at 18% TIN, paying 3% of the balance with a €25 minimum:

  • In the first month you pay €60.90.
  • After a year, €51.31.
  • After two years, €42.57.
  • From month 59 you pay the €25 minimum, until you finish in month 103.

With a fixed €60 payment, almost the same in the first month, you finish in month 47.

If your percentage is worked out on your limit or on the most you’ve ever owed, rather than on what you owe today, your payment doesn’t fall as you pay. It behaves more like a fixed instalment. Check your contract or ask your issuer.

How much does each way of paying cost?

In the example of €2,000 at 18% TIN, paying 3% of the balance costs almost twice the interest of a fixed €60 payment, even though you pay almost the same in the first month.

Way of paying First payment Months to zero Interest Total paid
Fixed €40 €40 94 €1,724 €3,724
3% of the balance, €25 minimum €60.90 103 €1,463 €3,463
Fixed €60 €60 47 €793 €2,793
5% of the balance, €25 minimum €101.50 63 €728 €2,728
Fixed €100 €100 24 €396 €2,396
Fixed €60 plus €45 of round-ups €105 23 €373 €2,373

5% of the balance starts at €101.50, more than the fixed €100, and still takes 63 months against 24.

Can the debt grow even if I pay every month?

Yes, if what you pay doesn’t cover the month’s interest. With €2,000 at 18% TIN, the card charges €30 of interest in the first month: with a payment under €30, the debt goes up instead of down.

Our calculator tells you if that’s your case: enter your balance, your TIN and your payment.

What does your issuer have to show you?

At least every quarter: when you’d finish paying if you stop using the card, and how much you’d pay in total, split between what you owe and interest. If a year of your payments repays less than 25% of your limit, also what would happen if you raised your payment by 20%, 50% or 100%, and what payment would clear it all in a year.

Orden EHA/2899/2011 says so, in the articles added by Orden ETD/699/2020. That 25% is what your issuer must aim for when assessing whether you can afford the credit, not a compulsory minimum payment. Banco de España explains that the higher-payment examples apply from 6 October 2022.

Also, if you ask, your issuer has to give you within five working days the payments you’ve made, what you owe and an amortisation table. All of this information is free.

How do I switch to a fixed or higher instalment?

Ask your issuer in its app, on its website or by phone. At WiZink and Cetelem you do it in the app, and Cetelem says the change is free and immediate.

What if I pay the full amount each month?

Then you pay no interest on purchases. WiZink says its full payment mode charges no interest, and Cetelem that its end-of-month mode is collected with no interest.

If you can pay everything you spend each month plus something toward the debt you already have, the debt stops growing with new purchases and falls faster.
