Your Summary
Explanation
About Car Payment Calculator
Knowing the monthly car payment up front makes budgeting easier. Provide the amount financed, the annual interest rate, and the term in months, and this calculator applies the amortization formula to return the payment.
Alongside it you will find the total interest and the total cost of the loan.
Formula & Mathematical Calculation
pmt = r === 0 ? (p ÷ n) : (p × r × pow(1 + r, n)) ÷ (pow(1 + r, n) - 1)
tot = pmt × n
Derived directly from the verified calculation function in the tool engine.
Calculation Example
For a $26,500 car loan at 5.25% annual interest over 60 months:
- Monthly rate r = 5.25 ÷ 100 ÷ 12 = 0.004375, and (1 + r)60 = 1.299432.
- Monthly Payment = 26,500 × 0.004375 × 1.299432 ÷ (1.299432 − 1) = $503.13.
- Total Cost, the payment applied across all 60 months, = $30,187.71.
- Total Interest = 30,187.71 − 26,500.00 = $3,687.71.
Key Benefits
- Returns a fixed monthly car payment for your amount, rate, and term.
