Explanation:
To calculate the monthly payment needed to pay off a credit card balance in a specific time frame, we can use the formula for the monthly payment on an amortizing loan:
Monthly Payment = (P * r * (1 + r)^n) / ((1 + r)^n - 1)
Where:
P = Principal balance (credit card balance)
r = Monthly interest rate (APR divided by 12 and converted to decimal)
n = Total number of monthly payments (number of years multiplied by 12)
Let's calculate the monthly payment for the given credit card balance and APR:
Principal balance (P) = $8500
APR = 17.99%
Monthly interest rate (r) = 17.99% / 12 / 100 = 0.0149958 (approximately)
Number of monthly payments (n) = 3 years * 12 months/year = 36
Substituting these values into the formula:
Monthly Payment = (8500 * 0.0149958 * (1 + 0.0149958)^36) / ((1 + 0.0149958)^36 - 1)
Using a calculator, the monthly payment is approximately $311.68 (rounded to the nearest cent).
Therefore, to pay off the credit card balance of $8500 in 3 years, you would need to make a monthly payment of $311.68.
