How to Calculate Your Car Payment
Enter the following information:
- Car Price: The total price of the vehicle
- Down Payment: Amount you're paying upfront
- Loan Term: Length of the loan in months
- Interest Rate: Annual percentage rate (APR)
Car Payment Formula
M = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Where:
- M = Monthly payment
- P = Principal (loan amount)
- r = Monthly interest rate (annual rate / 12)
- n = Number of payments
Example Car Payment Calculation
Car Price: $30,000
Down Payment: $6,000
Loan Amount: $24,000
Interest Rate: 7.5% annual (0.625% monthly)
Term: 60 months
Monthly Payment = 24,000 × [0.00625(1.00625)^60] / [(1.00625)^60 - 1]
Monthly Payment = $480.68
