How the Formula Works
Simple debt amortization logic behind the estimate.
1) Monthly interest rate = APR / 12. With your inputs, that is approximately 1.833% per month.
2) Each month: new balance = old balance + interest - payment. Interest shrinks as your balance declines.
3) Payoff month is when remaining balance reaches zero. This calculator assumes no new purchases and a constant APR.
Example 1: No Extra Payment
Balance $8,000, APR 22%, payment $250. Payoff takes multiple years and total interest can be substantial.
Example 2: Add $100 Monthly
With the same balance and APR, paying $350 instead of $250 usually shortens payoff time and lowers total interest.
Example 3: Payment Too Low
If monthly payment is below monthly interest, balance barely falls and payoff may not be achievable without increasing payment.
Credit Card Payoff FAQ
Why can credit card payoff take so long?
High APR means more of each payment goes to interest, especially when the balance is large. If payment is low relative to interest, payoff takes much longer.
Does making extra payments really help?
Yes. Extra payments reduce principal faster, which lowers future interest charges and usually shortens your payoff timeline.
What if my payment is below monthly interest?
In that case, balance will not decrease meaningfully and payoff may be impossible without increasing your payment or lowering APR.
Does this include late fees or new purchases?
No. This calculator assumes no new purchases, no missed payments, and a constant APR over time.
Should I use avalanche or snowball?
This tool models a single card. In multi-card plans, avalanche usually minimizes interest while snowball can improve motivation.
