Finance Calculators
Free financial calculators covering mortgages, loans, retirement, investments, taxes and everyday money math. Every tool runs instantly in your browser with no sign-up.
Planning a home purchase often starts with a mortgage calculator, but the fuller picture involves affordability, down payment goals, property tax, insurance, and DTI — each of which has a dedicated tool here.
For retirement planning, combine the retirement calculator (deterministic projection), investment calculator (Monte Carlo), and 401(k) calculator (employer match) to stress-test a plan under several return scenarios.
Debt decisions — whether to consolidate, refinance, or pay down cards with avalanche/snowball — are best informed by running multiple scenarios side-by-side in compare mode.
