Formula Explained
The auto loan calculator uses the standard amortization formula to calculate your monthly payments:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount ($39,900)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Number of payments (loan term in years × 12)
This formula calculates the fixed monthly payment required to fully amortize the loan over the specified term.
Worked Example
Let's calculate a $39,900 auto loan with a 5.5% annual interest rate over 5 years:
- Principal (P) = $39,900
- Annual interest rate = 5.5%
- Monthly interest rate (r) = 5.5% ÷ 12 ÷ 100 = 0.004583
- Number of payments (n) = 5 years × 12 = 60
Plugging these values into the formula:
Monthly Payment = $39,900 × (0.004583(1 + 0.004583)^60) / ((1 + 0.004583)^60 - 1)
Monthly Payment ≈ $743.25
Total interest paid over 5 years would be approximately $1,905.00, and the total repayment amount would be $41,805.00.
