Estimate the fixed monthly payment needed to amortize a credit-card balance, plus total interest and total repayment cost.
UNDERSTAND A ANSWER
Aika ng calculated el ua ngerang?
The balance is treated as an amortizing loan with a constant monthly APR and no new purchases or fees. At 0% APR, payment equals balance divided by the number of months.
Fixed-payment credit-card payoff formulaPayment = P × r(1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where r = APR ÷ 12
A practical example
For a $6,000 balance at 21% APR paid over 3 years, the estimated payment is about $226 per month and total interest is about $2,138.
