Enter Current Balance ($), Annual Interest Rate (%) and Minimum Payment (%) and the remaining scenario settings to review total interest paid with this tool. Each payment first covers modeled interest; only the remainder reduces the balance.
| Month | Payment | Interest | Principal | Balance |

Monthly payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1]
P = principal, r = periodic interest rate, n = number of payments.The calculation links Current Balance ($), Annual Interest Rate (%) and Minimum Payment (%) to total interest paid. Each payment first covers modeled interest; only the remainder reduces the balance. A payment that fails to cover interest cannot produce the intended payoff.

Estimate how long one card balance takes to repay at an entered rate and monthly payment. Check whether the planned payment meaningfully reduces principal.
Each payment first covers modeled interest; only the remainder reduces the balance. A payment that fails to cover interest cannot produce the intended payoff.
Prepare Current Balance ($), Annual Interest Rate (%), Minimum Payment (%) and Monthly Payment Amount ($). Use the statement balance and applicable APR, stop adding hypothetical purchases and compare two sustainable payment amounts.
Each payment first covers modeled interest; only the remainder reduces the balance. A payment that fails to cover interest cannot produce the intended payoff. Real cards may accrue interest daily and apply different rates to purchases, transfers or cash advances. New charges and changing minimums alter the result.
Use the full settings in the worked-example table. They produce Total Interest Paid: $1871.08; Total Paid: $6871.08. Compare the method and units as well as the displayed number.
The displayed relationship is Monthly payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1] P = principal, r = periodic interest rate, n = number of payments. Use the statement balance and applicable APR, stop adding hypothetical purchases and compare two sustainable payment amounts.
Real cards may accrue interest daily and apply different rates to purchases, transfers or cash advances. New charges and changing minimums alter the result. For a transaction or account decision, compare the inputs with the applicable statement, contract or official rules.
Worked credit card calculator example. Set Current Balance ($) = 5000; Annual Interest Rate (%) = 22.99; Minimum Payment (%) = 2; Monthly Payment Amount ($) = 200. The corresponding output is Total Interest Paid: $1871.08; Total Paid: $6871.08. Each payment first covers modeled interest; only the remainder reduces the balance.

| Field | Example value | Entry check |
|---|---|---|
| Current Balance ($) | 5000 | Check whether this amount is one-time, monthly or annual before entering it. |
| Annual Interest Rate (%) | 22.99 | Enter a percentage in the form requested by the field, keeping its stated time basis. |
| Minimum Payment (%) | 2 | Enter a percentage in the form requested by the field, keeping its stated time basis. |
| Monthly Payment Amount ($) | 200 | Use the amount for this scenario in the currency and period shown by the field. |
Relationship used for this example: Monthly payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1] P = principal, r = periodic interest rate, n = number of payments.
Each payment first covers modeled interest; only the remainder reduces the balance. A payment that fails to cover interest cannot produce the intended payoff.
| Output | Displayed result |
|---|---|
| Total Interest Paid | $1871.08 |
| Total Paid | $6871.08 |
With these settings, total interest paid is $1871.08. Use the same units and calculation mode when reproducing this example.
Each payment first covers modeled interest; only the remainder reduces the balance. A payment that fails to cover interest cannot produce the intended payoff. Real cards may accrue interest daily and apply different rates to purchases, transfers or cash advances. New charges and changing minimums alter the result.
Replace the illustrative current balance ($) value (5000) with your own value, then complete the other inputs for the same scenario. Use the statement balance and applicable APR, stop adding hypothetical purchases and compare two sustainable payment amounts.
