Frequently asked questions

How does the calculator work?

It approximates monthly interest as APR divided by 12 and applies your payment until the modeled balance reaches zero.

Why can high-APR debt take so long?

A high APR can consume a large part of each payment as interest, especially when the payment is small.

Does paying extra help?

Generally, paying more reduces the balance faster and can reduce future interest under the model.

Is this exact?

No. Card issuers may calculate interest daily and can apply fees, purchases and statement-cycle rules.
