About the Debt Payoff Calculator
What is the Debt Payoff Calculator?
A debt payoff calculator estimates when a loan or card balance will be cleared and how much interest you will pay, with an optional extra payment.
Why use this calculator?
Seeing a concrete debt-free date is one of the strongest motivators for sticking to a payoff plan, and it shows exactly what an extra payment buys you.
How to use it
- Enter the balance, interest rate and monthly payment.
- Add an optional extra payment.
- See the payoff date, total interest and the savings from the extra.
Formula
Loop: interest = balance × rate ÷ 12; principal = payment − interest.
Assumes no new charges and a constant rate.
Frequently Asked Questions
What if my payment does not cover the interest?
The balance grows instead of shrinking. Increase the payment above the monthly interest charge to make any progress.
Does the order of paying debts matter?
Paying the highest-rate debt first minimizes total interest. Paying the smallest first can be more motivating psychologically.
What is a credit utilization ratio?
It is the share of your available credit that you are using. Keep it below 30%, and ideally below 10%, to protect your credit score.
Will paying off a card hurt my score?
No. Paying down balances usually helps your score by lowering utilization. Closing the account, however, can reduce your available credit.
What is the minimum payment trap?
Minimum payments are set low, so most of the payment goes to interest and the balance lingers for years. Paying more than the minimum saves substantial interest.
Should I consolidate my debts?
Consolidation can lower your interest rate and simplify payments, but it only works if you stop adding new debt. Compare the new APR and any fees first.
