Formula for Car Loan Extra Payments
The standard formula for calculating monthly car loan payments is:
Monthly Payment (M) = [P × r × (1 + r)^n] ÷ [(1 + r)^n – 1]
Where:
- P = Principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in months)
When adding extra payments, the formula is applied iteratively:
- Subtract the extra payment from the principal each month.
- Recalculate interest on the new principal.
- Continue until the principal is paid off.
This reduces both the total interest and the loan duration.
Example Calculation
Suppose you have a $25,000 car loan at 6% annual interest for 5 years (60 months), and you plan to pay an extra $100 per month.
- Monthly interest rate: r = 6 ÷ 12 ÷ 100 = 0.005
- Standard monthly payment:
M = [25,000 × 0.005 × (1 + 0.005)^60] ÷ [(1 + 0.005)^60 – 1]
Step-by-step:
- (1 + 0.005)^60 ≈ 1.34885
- Numerator = 25,000 × 0.005 × 1.34885 ≈ 168.61
- Denominator = 1.34885 – 1 = 0.34885
- M ≈ 168.61 ÷ 0.34885 ≈ $483.78
- Add extra payment: 483.78 + 100 = $583.78/month
By paying $583.78 monthly instead of $483.78, the loan will be paid off faster and total interest will be significantly reduced.
