Financial Calculators
Loan Payoff Calculator
Estimate how long it will take to pay off a loan and how extra payments can help.
Estimate your loan payoff timeline before making a payment decision.
Enter your current balance, annual interest rate, regular monthly payment, and any optional extra payment. The calculator estimates payoff time and interest using a monthly payment schedule. It is a private browser estimate, not financial advice; confirm terms, fees, and payment details with your lender.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
How does the loan payoff calculator estimate payoff time?
It applies the monthly interest rate to the remaining balance, subtracts each monthly payment, and repeats until the estimated balance reaches zero. The result assumes the rate and payment stay the same.
How do extra monthly payments affect my loan payoff?
An extra monthly payment reduces the balance faster. The calculator compares the estimated schedule with and without that extra amount to show potential time and interest savings.
Do my loan values leave my browser?
No. The calculation runs locally in your browser. CodeASystem does not upload or store the balance, rate, or payment values you enter.
