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
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment for a loan with a fixed interest rate.

Worked Example

Let's calculate a loan for $20,000 at 5% annual interest over 4 years:

Principal (P) = $20,000
Annual interest rate = 5% (0.05)
Monthly interest rate (i) = 0.05/12 ≈ 0.004167
Number of payments (n) = 4 × 12 = 48

Plugging these into the formula:

Calculation Steps

M = 20,000 [ 0.004167(1 + 0.004167)^48 ] / [ (1 + 0.004167)^48 - 1 ]

M ≈ $456.24 per month

Total interest paid would be $3,169.44, and total loan cost would be $23,169.44.
