Formula Used in the Calculation
The monthly payment for a car loan is calculated using the standard loan payment formula:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
This formula accounts for the interest charged on the outstanding loan balance each month, which is then added to the principal amount.
Worked Example
Let's calculate a car loan with the following details:
- Loan amount: $25,000
- Annual interest rate: 5%
- Loan term: 5 years
Using the formula:
Monthly interest rate = 5% ÷ 12 = 0.0041667
Number of payments = 5 × 12 = 60
Monthly payment = $25,000 × (0.0041667(1 + 0.0041667)^60) / ((1 + 0.0041667)^60 - 1)
Monthly payment ≈ $454.23
Total interest paid over 5 years: $2,232.20
Total amount paid: $27,232.20
