What is a credit card overpayment?

A credit card overpayment means paying more than the required minimum. This helps reduce your balance faster and lowers the interest charged.

How does this calculator work?

This tool lets you simulate one-off and regular overpayments to estimate how much interest you'll save and when your debt will be paid off.

What if I pay just the minimum?

Only paying the minimum will stretch your debt over many years and increase interest costs. Use this tool to see how much faster you could repay with overpayments.

Can I add both regular and one-off payments?

Yes. You can model multiple overpayment scenarios together to understand how they combine to reduce your credit card balance more quickly.
