How is a credit card minimum payment calculated?

Commonly interest plus 1% of the balance, or a flat 2–3% of the balance, whichever your issuer uses — subject to a floor of around $25–$35. $5,000 at 20% gives $83.33 interest + $50 = $133.33.

What happens if I only pay the minimum?

$5,000 at 20% APR takes around 19 years and costs roughly $7,300 in interest — more than you borrowed. The minimum shrinks as the balance shrinks, which is what stretches it out.

What's the easiest way to pay off a card faster?

Freeze your payment. Keep paying today's minimum amount every month instead of letting it fall with the balance. It costs nothing extra after the first month and cuts years off.

Why is so much of my minimum payment interest?

Because the minimum is designed to be just above the interest charge. On $5,000 at 20%, about 63% of a $133.33 minimum is interest and only $50 reduces the debt.

Minimum Payment Calculator Guide

This shows what your minimum payment is, what it's made of, and what happens if the minimum is all you ever pay.

The Common Rules

Interest + 1% of balance — $5,000 at 20% gives $83.33 interest + $50 = $133.33
Flat percentage — commonly 2–3% of the balance
Both usually sit under a floor of around $25–$35.

Why the Minimum Is Designed That Way

Look at the split. On $5,000 at 20%, a $133.33 minimum sends $83.33 to interest and just $50 to the debt. Roughly 63% of your payment buys nothing.

And because the minimum is a percentage of a shrinking balance, it shrinks too — always keeping you a decade or two from the finish. The minimum is not a payment plan. It's the smallest amount that keeps the account in good standing while the balance earns for the issuer.

The Trap in One Number

$5,000 at 20% APR, paying only the minimum, takes around 19 years and costs roughly $7,300 in interest — more than the original balance.

The same balance at a fixed $200 a month clears in about 32 months for around $1,400. Same debt, same rate. The only difference is refusing to let the payment shrink.

The Single Best Move

Fix your payment. Pick an amount above today's minimum and keep paying exactly that, every month, as the balance falls.

This costs nothing extra beyond the first month, and it's the whole game — because it stops the payment shrinking as the balance shrinks, so every month a larger share hits principal. Most of the horror in minimum-payment maths comes from the declining payment, not from the rate.

Your Statement Already Tells You This

In many countries, card statements are legally required to show how long the balance would take to clear at the minimum, and what a payment that clears it in three years would look like. That box exists because the numbers are so bad that regulators decided people had to see them.

Check Your Own Agreement

Minimum payment formulas vary by issuer and by country, and they change. Some use interest + 1%, some 2–3% flat, some add fees and past-due amounts on top. This calculator uses whichever rule you select — check your cardholder agreement rather than assuming.
