Formula Used
The calculator uses the standard auto loan payment formula:
Auto 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 × 12)
This formula calculates the fixed monthly payment required to pay off the loan over the specified term.
Worked Example
Let's calculate the monthly payment for a $25,000 car loan with a 4.5% annual interest rate over 5 years.
- Principal (P) = $25,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (r) = 0.045 / 12 ≈ 0.00379
- Loan term in months (n) = 5 × 12 = 60
Plugging these values into the formula:
Calculation
Monthly Payment = $25,000 × (0.00379 × (1 + 0.00379)^60) / ((1 + 0.00379)^60 - 1)
Monthly Payment ≈ $25,000 × (0.00379 × 1.2456) / (1.2456 - 1)
Monthly Payment ≈ $25,000 × 0.0479 / 0.2456
Monthly Payment ≈ $25,000 × 0.1949 ≈ $4,872.50
The estimated monthly payment for this loan would be approximately $4,872.50.
