The calculator uses the standard auto loan payment formula to provide an accurate estimate. You can also view a breakdown of your loan payments over time.
Formula Used
The auto loan calculator uses the following formula to calculate monthly payments:
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 × 12)
This formula accounts for the interest on the loan balance over time, providing an accurate estimate of your monthly payments.
Worked Example
Let's calculate an example auto loan:
- Loan Amount: $25,000
- Annual Interest Rate: 5%
- Loan Term: 5 years
Using the formula:
Monthly interest rate (r) = 5% ÷ 12 = 0.0041667
Number of payments (n) = 5 × 12 = 60
Monthly Payment = $25,000 × (0.0041667(1 + 0.0041667)^60) / ((1 + 0.0041667)^60 - 1)
Monthly Payment ≈ $452.87
Total interest paid over 5 years would be approximately $1,826.20.
