Formula Used
The calculator uses the standard auto loan payment formula:
Monthly Payment Formula
M = P [i(1 + i)n] / [(1 + i)n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount (Vehicle Price - Down Payment)
- i = Monthly interest rate (Annual Rate / 12 / 100)
- n = Number of payments (Loan Term in years × 12)
This formula calculates the fixed monthly payment for a loan with a fixed interest rate. The calculator also computes the total interest paid and total loan cost by multiplying the monthly payment by the number of payments and subtracting the principal.
Worked Example
Let's calculate a monthly payment for a $25,000 car loan with a 5% annual interest rate and a 5-year term:
- Principal (P) = $25,000 - $0 (no down payment) = $25,000
- Monthly interest rate (i) = 5% / 12 = 0.4167%
- Number of payments (n) = 5 × 12 = 60
- Monthly payment (M) = $25,000 [0.004167(1 + 0.004167)60] / [(1 + 0.004167)60 - 1] ≈ $461.48
Total interest paid = ($461.48 × 60) - $25,000 = $1,140.80
Total loan cost = $25,000 + $1,140.80 = $26,140.80
Note
Actual payments may vary slightly due to rounding and additional fees that may apply.
