Formula Used
The auto loan calculator uses the standard mortgage 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 calculates the fixed monthly payment required to pay off the loan over the specified term.
Worked Example
Let's calculate a monthly payment for a $20,000 loan with a 5% annual interest rate over 4 years:
- Principal (P) = $20,000
- Annual interest rate = 5% or 0.05
- Monthly interest rate (r) = 0.05 / 12 ≈ 0.004167
- Number of payments (n) = 4 × 12 = 48
Monthly Payment = $20,000 × [0.004167(1 + 0.004167)^48] / [(1 + 0.004167)^48 - 1]
Monthly Payment ≈ $452.34
Total interest paid over 4 years would be approximately $1,711.44, and the total amount paid would be $21,711.44.
