Calculateur de Auto Loan
Estimate monthly car loan payments from price, down payment, rate, and term.
Formula and method
This calculator computes Monthly payment directly in your browser without sending data to an external server.
Mathematical formula
- Monthly payment:
price<down ? NaN : (rate===0) ? ((price-down) ÷ (years × 12)) : (((price-down) × (rate ÷ 1200)) ÷ (1-1+(rate ÷ 1200)^(-(years × 12))))
Variables and parameters
- Vehicle price (price): default value 30000.
- Down payment (down): default value 3000.
- Annual interest rate (rate): default value 7 %.
- Loan term (years): default value 5 years.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
