Loan payoff calculator.
Any fixed-rate loan. Enter the balance, rate and payment, add extra payments or a lump sum, and see how early you are done and how much interest you skip.
Paid on top of the regular payment, straight to principal.
Debtless keeps all your debts on one plan and moves your debt-free date as you pay. Free on iPhone.
What to enter.
- [ 01 ]
Balance owed
The current principal from your statement or the lender's app, not the original amount borrowed. - [ 02 ]
Rate and term
The APR, and either the months left or your regular payment. Either one lets the calculator rebuild the schedule. - [ 03 ]
Extra and lump sum
What you can add each month, and any one-off amount you can pay now. - [ 04 ]

New payoff month, months sooner, interest saved, and the chart of both balances over time.
Loans this works for.
Any loan where interest is charged monthly on the remaining balance: car loans, personal loans, student loans with a fixed rate, mortgages, and buy-now-pay-later plans that charge interest. Dedicated pages with matching defaults: car loan, personal loan, mortgage.
Credit cards are different because the minimum payment changes every month. Use the credit card minimum payment calculator for those.
