Explanation

About Car Loan Balance Calculator

This calculator shows how much you still owe on a fixed-rate car loan after a given number of monthly payments. Enter the original loan amount, the annual interest rate, the full term in months, and how many payments you have already made; it returns the outstanding balance, the fixed monthly payment, and the principal paid down so far.

The remaining balance uses the standard amortization formula B = P(1+r)^k − PMT×((1+r)^k − 1)/r, where r is the monthly rate and k is the number of payments made. A zero interest rate and payment counts beyond the term are handled correctly, with the balance never falling below zero.

Formula & Mathematical Calculation

Monthly Payment = (P × r × (1 + r)^n) ÷ ((1 + r)^n − 1)

Remaining Balance = P × (1 + r)^k − Payment × (((1 + r)^k − 1) ÷ r)

r is the monthly rate, n the full term in months, and k the number of payments already made (capped at n; the balance never falls below zero).

Calculation Example

On a $24,000 loan at 5.5% over 48 months, the fixed monthly payment is $558.16. After 12 payments, about $18,484.48 is still owed and roughly $5,515.52 of principal has been paid down.

Assumptions & Limitations

What the calculation assumes

  • Every value you enter is treated as an exact, known amount.
  • Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
  • Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
  • Inflation, tax changes and market volatility are not modelled unless a field for them is provided.

  • Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
  • Figures are only as accurate as the inputs you supply — check them before acting on the result.
  • For decisions with lasting financial impact, confirm the numbers with a qualified professional.

Frequently Asked Questions

With the amortization balance formula B = P(1+r)^k − PMT×((1+r)^k − 1)/r, where P is the original amount, r the monthly rate, PMT the monthly payment, and k the payments already made.

The loan is treated as fully repaid and the outstanding balance is shown as zero.

Enter the annual interest rate; the calculator divides it by 12 to get the monthly rate.
