Credit Card Payoff Calculator — How Long Until You Are Debt Free?

Find out how long it will take to pay off your credit card and how much interest you will pay. Includes worked examples and strategies to clear debt faster.

If you owe £3,000 on a credit card at 22% APR and pay £100 per month, it will take approximately 3 years and 2 months to pay off the balance and you will pay around £1,150 in interest on top of the original debt. Paying only the minimum (typically 2% of the balance) stretches repayment to over 20 years and costs thousands more.

Worked Example

Credit card details:

  • Balance: £3,000
  • APR: 22%
  • Monthly payment: £100 (fixed)
Fixed £100/monthMinimum payment (2%)
Time to pay off3 years 2 months20+ years
Total interest paid£1,150£4,800+
Total repaid£4,150£7,800+

The difference is stark. Fixing your monthly payment at a set amount rather than paying the minimum is the single most effective way to reduce credit card interest costs.


Why Credit Card Debt Is So Expensive

Credit cards charge compound interest on your outstanding balance, typically at rates between 18% and 30% APR. Unlike a mortgage or personal loan where the rate might be 3–7%, credit card rates are several times higher.

On a £5,000 balance at 25% APR with minimum payments:

  • You would pay the debt off in roughly 35 years
  • Total interest: over £14,000 — nearly three times the original balance

Three Strategies to Pay Off Faster

1. Pay More Than the Minimum

Even an extra £50 per month makes a dramatic difference. On a £3,000 balance at 22%, increasing your payment from the minimum to £150/month cuts your payoff time from 20+ years to just over 2 years.

2. Balance Transfer

A 0% balance transfer card lets you pay down the principal without interest for a promotional period (typically 12–24 months). You will usually pay a transfer fee of 2–3%.

3. Avalanche Method

If you have multiple cards, pay the minimum on all of them and direct any extra money to the card with the highest interest rate first. Once that is cleared, move to the next.


When to Consider a Personal Loan Instead

If your credit card balance is large and the APR is high, a personal loan at a lower rate can reduce your monthly cost and give you a fixed repayment date. Use our Loan Calculator to compare.
