About this calculator
How debt payoff works
Each month, interest is charged on the remaining balance. Your payment covers that interest first, then the rest reduces the principal. This is why high-rate debt is so expensive: early payments barely touch the balance.
The power of paying more
Increasing your monthly payment even slightly can save a significant amount. On a €5,000 credit card balance at 18%, paying €200/month instead of €150/month saves around 14 months and several hundred euros in interest.
Debt payoff strategies
- Avalanche: Pay minimum on all debts; throw extra money at the highest-rate debt first. Minimizes total interest paid.
- Snowball: Pay minimum on all debts; throw extra money at the smallest balance first. Builds psychological momentum.
Both outperform paying minimums on everything. Use this calculator on each debt to see the numbers clearly.
What to do after payoff
Once a debt is paid off, redirecting those payments into savings or investments — with the same discipline — is one of the fastest ways to build wealth.

Frequently asked questions
Why is so much of my payment going to interest?
Early in a loan, the interest charge on the remaining balance is high. As the balance falls, more of each payment goes to principal. This is why high-rate debts like credit cards are so expensive — a large portion of each payment just covers interest.
How much do extra payments help?
Extra payments directly reduce the balance, which reduces the interest charged in subsequent months. Try increasing the monthly payment in this calculator — even €20–50 more per month on a credit card balance can save months and hundreds in interest.
What order should I pay off multiple debts?
The avalanche method (highest rate first) minimises total interest. The snowball method (smallest balance first) builds momentum with quick wins. Either beats paying minimums on everything. Use this calculator to compare the total cost of each approach.
