Debt Calculator Free — No Signup, No App, No Data Collected

Your debt balances are private. You should not have to create an account or hand over personal data to run a calculation. The Debt Payoff Calculator runs entirely in your browser. Nothing is stored.

What You Get

• Add any number of debts with name, balance, APR, and minimum payment
• Compare snowball vs avalanche with one toggle
• Set extra monthly payments and see the impact
• See payoff date, total interest, and how much extra payments save
• Works on phone, tablet, or computer

Why No Account?

Account-based calculators store your financial data on their servers. Your debt balances and interest rates tell companies a lot about your financial situation. A browser-based calculator avoids that. The JavaScript runs on your device. When you close the tab, the data is gone.

Why No App?

A debt calculator does not need access to your phone, push notifications, or location data. A browser tab does the same math without any overhead. Apps take storage, require updates, and can be discontinued.

How to Save Your Results
