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.
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).
A common starting framework splits monthly take-home pay into needs, wants and saving or debt payoff. Enter your take-home pay, then adjust the three shares if you want. They always add to 100 percent.
A 50 / 30 / 20 split is a general guideline, not a rule. The right mix depends on your cost of living, income stability and goals. Education only, not financial advice.
An emergency fund is money set aside for essential costs if income stops or a large bill lands. Enter your essential monthly spending and how many months you want to cover, then how much you can save each month to see how long the goal takes.
A common general guideline is three to six months of essential expenses, built up gradually. The right size depends on your household. This estimate assumes a steady monthly saving amount and does not include interest earned. Education only, not financial advice.
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.
