Formula Used
The calculator uses the standard auto loan payment formula:
Total Interest = (Monthly Payment × Number of Payments) - Principal
Total Amount Paid = Principal + Total Interest
Worked Example
Let's calculate a $25,000 auto loan with a 4.5% APR over 5 years:
- Principal = $25,000
- Monthly rate = 4.5%/12 = 0.00375
- Number of payments = 5 × 12 = 60
- Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $465.23
- Total Interest = ($465.23 × 60) - $25,000 ≈ $1,123.80
- Total Amount Paid = $25,000 + $1,123.80 ≈ $26,123.80
Note: Actual payments may vary slightly due to rounding and lender-specific calculations.
