Formula Explained
The car auto loan payment calculator uses the standard loan payment formula:
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 multiplied by 12)
This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.
Worked Example
Let's calculate a car loan payment with these assumptions:
- Loan amount: $25,000
- Loan term: 5 years
- Annual interest rate: 4.5%
Using the formula:
Calculation Steps
1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
2. Calculate number of payments: 5 years × 12 = 60 payments
3. Plug values into formula: M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 - 1 ]
4. Calculate the result: M ≈ $454.23
Your monthly payment would be approximately $454.23, with a total interest of $3,262.40 over the life of the loan.
