The payoff result estimates how long it will take to clear the entered card balances and how much interest you may pay. The strategy changes which card receives extra payments first.
Inputs that matter most
- APR: higher rates make balances more expensive to carry.
- Minimum payments: affect how quickly each balance can shrink.
- Extra monthly payment: usually has the biggest impact on payoff time.
- Strategy: avalanche targets interest cost; snowball targets faster early wins.
Common mistakes
- Adding new purchases while relying on the payoff timeline.
- Comparing strategies without entering realistic minimum payments.
- Ignoring balance transfer fees or promotional APR end dates.
- Stopping extra payments after the first card is paid off.
When this estimate can be misleading
This estimate assumes no new purchases, no missed payments, stable APRs, and the entered payment plan each month. Actual card minimum payment rules can vary by issuer.
Scenarios to try
- Compare avalanche and snowball with the same extra payment.
- Increase extra payment by $50 or $100 to see payoff acceleration.
- Test a balance transfer by lowering APR and adding any transfer fee manually.
- Remove one card after payoff to see how the remaining plan changes.

Snowball vs. avalanche payoff methods
Both methods roll freed-up minimum payments into the next card after a balance is paid off.
The debt snowball method focuses extra payments on the smallest balance first. It can create quicker early wins and make the payoff plan easier to stick with.
The debt avalanche method focuses extra payments on the highest APR first. It usually reduces total interest paid when all other assumptions are the same.
People who need motivation or who have several small balances often compare snowball first because closing accounts can feel tangible. People optimizing for interest savings usually compare avalanche first because high APR balances are the most expensive to carry.
Neither method helps if new purchases keep adding to the balance. For a realistic plan, enter payments you can sustain every month and use the charts to see whether the payoff timeline still feels workable.
Credit card payoff assumptions
The calculator simulates balances month by month using the entered APRs, minimum payments, extra payment, and selected payoff strategy.
Monthly interest is estimated from APR divided by 12 and applied to the remaining balance. Payments are applied to interest first, then principal.
The estimate assumes APRs and monthly payments stay the same. It does not include new purchases, late fees, balance transfer fees, promotional rate changes, or lender-specific minimum payment rules.
If the minimum payment is too low to cover monthly interest, the balance may not pay down. In that situation, the calculator helps show that a higher payment, lower APR, or other debt strategy may be needed.
Credit card payoff FAQ
Which payoff method saves more interest?
The avalanche method usually saves more interest because it targets the highest APR first.
Why might someone choose snowball instead?
Snowball can pay off smaller balances sooner, which may make the plan easier to maintain.
Does this include new purchases?
No. The estimate assumes no new purchases, fees, or APR changes after the starting balances are entered.
Should I include cards with promotional APRs?
You can, but enter the APR that will apply during most of the payoff period or rerun the estimate when the promotional rate changes.
