How to Use This Calculator

Using this auto loan calculator is simple:

Enter the loan amount you're considering (e.g., $25,000)

Formula Used

The calculator uses the standard auto loan 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 $25,000 loan at 4.5% interest for 5 years (60 months):

Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375
Using the formula:
M = 25000 [ 0.00375(1 + 0.00375)⁶⁰ ] / [ (1 + 0.00375)⁶⁰ - 1 ]
Calculating the components:
- (1 + 0.00375)⁶⁰ ≈ 1.289
- Numerator = 25000 × 0.00375 × 1.289 ≈ 122.34
- Denominator = 1.289 - 1 = 0.289
- M ≈ 122.34 / 0.289 ≈ $423.32

So your estimated monthly payment would be $423.32.
