Compare loans, split bills, calculate paychecks, and plan savings goals. All finance tools run locally in your browser.
Finance & Money keeps everyday money math honest and private. Split a bill or shared rent fairly, compare loan offers side by side so the real cost is obvious, see what a paycheck nets after deductions, and set a savings goal with a plan that reaches it by the date you choose. Every calculator runs locally in your browser and shows its working, so you can double-check a number in seconds without creating an account or uploading a file.
How is the per-person amount calculated?
The tip is added to the bill, then the total is divided evenly by the number of people.
What is the monthly payment formula?
It uses the standard amortization formula: P = (r * PV) / (1 - (1 + r)^-n), where r is the monthly rate and n the number of payments.
How accurate is this estimate?
It gives a rough estimate using flat percentages for federal, state, and other deductions. Actual withholdings depend on your W-4 and local laws.
How does compound interest work here?
Your balance earns interest monthly on both your current savings and the accumulated interest, and your monthly contributions are added each period.
