Step-by-Step Calculation
- Determine your loan amount. Car price minus down payment.
- Convert your annual rate to a monthly rate. Divide APR by 12.
- Count total payments. Loan term in years × 12.
- Apply the EMI formula (see Formula tab) to get your fixed monthly payment.
Worked Example
You finance $25,000 at 6% APR over 5 years (60 months).
Monthly rate = 0.06/12 = 0.005
EMI = 25000 × [0.005(1.005)^60] / [(1.005)^60 − 1] ≈ $483/month
Over 60 months, you'll pay $28,980 total — meaning $3,980 of that is pure interest. Shortening the term to 48 months raises the EMI to about $587 but cuts total interest to roughly $3,176 — an $800 savings for tolerating a higher monthly payment.
Frequently Asked Questions
Does a larger down payment always help?
Yes — a bigger down payment reduces the financed principal directly, lowering both your EMI and total interest paid, and can also help you qualify for a better interest rate.
Can I pay off a car loan early without penalty?
Most auto loans allow early payoff, but some include prepayment penalties — always check your loan agreement before making extra payments toward the principal.
