Debt payoff

- Minimum Payment Trap Calculator: what paying only the minimum costs over time, and the zero-cost fix
Interest and ratios
- Credit Card Interest Calculator: what your balance costs per day, month, and year
- Credit Utilization Calculator: per-card and overall ratios, and exactly how much to pay down before your statement closes
A $400 emergency is the test in the Fed’s household survey. In the 2025 public file, 63.1% of adults would have paid it with cash or its equivalent and nothing else, by our count of that file. It is not the Fed’s published headline. If the $400 would go on a card, the payoff and minimum-payment calculators above are the next step.
For context on your own numbers: required debt payments were 11.11% of disposable income nationally in the second quarter of 2026, and 16.5% of adults used buy now, pay later in 2025. Both are averages and say nothing about your budget.
In development: balance transfer savings, loan payments, debt-to-income, and wage garnishment. If a calculator here ever gives you a number that looks wrong, tell us — the math is the product.
