Car Loan Payment Formula Explained
The standard formula used to calculate a fixed monthly payment (M) for a loan, also known as the amortization formula, is:
M = P [ i(1 + i)n ] / [ (1 + i)n – 1 ]
- M = Monthly Payment
- P = Principal Loan Amount (the total amount borrowed)
- i = Monthly Interest Rate (Annual Interest Rate / 12 / 100)
- n = Total Number of Payments (Loan Term in Years × 12)
Example Calculation:
Let's say you borrow $25,000 (P) for a car loan at an annual interest rate of 4.5% over 5 years.
- P = $25,000
- i = 4.5% / 12 / 100 = 0.045 / 12 = 0.00375
- n = 5 years × 12 months/year = 60 payments
Plugging these values into the formula:
M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 – 1 ]
M = 25000 [ 0.00375(1.00375)60 ] / [ (1.00375)60 – 1 ]
M ≈ $466.82
This means your estimated monthly car loan payment would be approximately $466.82.
