TopToolsAiSee how long it will take to pay off a credit card balance at a given interest rate and monthly payment, and how much total interest you'll end up paying. A PKR 100,000 balance at 3% monthly interest, paying only PKR 5,000 a month, takes more than 2 years to clear and racks up over PKR 25,000 in interest alone — a clear illustration of why minimum payments keep a balance alive for so long.

Frequently asked questions
Why does a small payment increase take off so much time?
Because credit card interest compounds monthly — a bigger chunk of each payment goes to principal instead of interest, which snowballs the payoff speed.
What if my payment doesn't cover the interest?
The calculator will warn you if your payment is too low to ever pay down the balance — you would need to increase it.
Why is credit card interest so much higher than a bank loan?
Credit cards are unsecured, revolving debt, so issuers charge higher rates to offset the greater risk compared to a secured loan like a mortgage.
Should I pay off my credit card before saving or investing?
Since credit card rates are usually far higher than typical investment returns, paying it off first is generally the better financial move.
