Formula Used
The car auto payment calculator uses the standard loan payment formula:
Loan Payment Formula
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = 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 the monthly payment for a $25,000 car loan with a 5% annual interest rate over 5 years.
| Input | Value |
|---|---|
| Loan Amount | $25,000 |
| Interest Rate | 5% |
| Loan Term | 5 years |
Using the formula:
Calculation Steps
1. Convert annual rate to monthly: 5% ÷ 12 = 0.4167% or 0.004167
2. Calculate number of payments: 5 years × 12 = 60 months
3. Plug values into formula: $25,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
4. Result: $456.24 per month
So, the estimated monthly payment for this loan would be $456.24.
