Formula Used
The OneAZ Auto Loan 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 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 an example auto loan:
Example Scenario
Loan Amount: $25,000
Interest Rate: 5.5% APR
Loan Term: 5 years
Using the formula:
- Convert annual rate to monthly: 5.5% ÷ 12 = 0.4583% or 0.004583
- Number of payments: 5 years × 12 = 60 payments
- Plug values into formula: M = 25000 [ 0.004583(1 + 0.004583)^60 ] / [ (1 + 0.004583)^60 - 1 ]
- Calculate: M ≈ $468.24 per month
Total interest paid over 5 years: $2,901.60
Final payoff date: Approximately 5 years from today's date
