How this calculator works
Adds the extra payment to the stated monthly payment.
Each month, charges balance × APR / 12 and applies the payment.
Stops when the final payment clears the balance.
Worked example
Worked example: a $1,000 balance at 12.00% APR paid at $100 per month takes 11 months and costs $58.98 in this monthly model.
Common questions
Why can this differ from my statement?
Many issuers use daily balances and may apply different APRs to different balance categories.
What if my payment is below interest?
The tool rejects it because the balance would not amortize under this simplified model.
