Money toolkit

Three plain-math money calculators

Private and free, everything runs in your browser and nothing you type leaves your device. Plan a debt payoff, split a paycheck, or size an emergency fund, using real arithmetic you can check.

Debt payoff planner

Add each debt with its balance, annual rate (APR) and minimum payment, then a total extra you can put toward debt each month. The planner runs the real month-by-month math and compares two common orders: snowball (smallest balance first) and avalanche (highest rate first).

Enter your debts and press Calculate to compare snowball and avalanche.

These calculators do arithmetic on the numbers you enter. They are educational and are not financial, investment, tax or legal advice, and not a recommendation of any product. Results are estimates that assume rates and payments stay constant, which real life rarely does. Decisions about your own money should reflect your own situation, and where needed, a qualified professional.
