Understand the estimate
What your result means
The payoff time and total interest use your base monthly payment plus the additional amount. Interest saved and months saved compare that scenario with the base monthly payment alone. Both scenarios must repay the balance for this comparison to be available. Card issuers may use different daily-balance methods, fees, and minimum-payment rules.
When a payment is only slightly above modeled monthly interest, little goes toward reducing principal, so payoff can take much longer. Increasing the monthly payment can reduce the modeled payoff time and interest.
Before you enter a value
What should I enter?
- Card balance
- Enter the balance you want to pay down; this simplified model does not include future purchases, fees, or issuer-specific billing rules.
- APR
- Enter the annual percentage rate for the balance. The calculator models monthly interest from that rate.
- Monthly payment
- Enter your fixed base monthly amount in Minimum payment and any extra recurring amount in Additional payment. The model holds both amounts constant; it does not recalculate an issuer’s minimum as the balance falls.
Worked example
Example: adding $75 to a $6,500 card payment
Inputs
- Card balance: $6,500
- APR: 22.9%
- Base monthly payment: $175
- Comparison payment: $250 per month
Results
- At $175 per month: about 66 months and $4,922 total interest
- At $250 per month: about 37 months and $2,566 total interest
- In this model, the larger payment shortens payoff by about 29 months and reduces modeled interest by about $2,356
These figures use the current monthly payoff model with no new charges or fees. They are estimates, not a card-issuer payoff statement.
Important considerations
Before you decide
- Focusing only on the payment amount instead of the total interest and payoff time.
- Assuming every card calculates interest or minimum payments the same way.
- Ignoring new purchases, fees, or changes in APR that are not modeled.

Common questions
Before you decide
How long will it take to pay off my credit card?
This calculator estimates a payoff timeline from the balance, APR, and monthly payment you enter.
How does APR affect credit card payoff?
A higher APR increases the monthly interest modeled on the remaining balance, which can lengthen payoff and raise total interest.
What happens if I increase my monthly payment?
Based on fixed inputs, a larger payment can reduce the modeled payoff time and interest. Actual card behavior can differ.
Why is my balance falling slowly?
When much of a payment goes to interest, less is left to reduce principal. Fees, new purchases, and issuer rules can also matter.
