Formula Used
The auto payments calculator uses the standard 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 $20,000 loan at 4.5% annual interest over 5 years:
- Principal (P) = $20,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (r) = 0.045 / 12 = 0.00375
- Number of payments (n) = 5 × 12 = 60
Plugging these values into the formula:
Monthly Payment = $20,000 × [0.00375(1 + 0.00375)60] / [(1 + 0.00375)60 - 1]
Monthly Payment ≈ $362.87
So, the estimated monthly payment for this loan would be $362.87.
