percent How the math works

We use the standard amortization, compound-interest and present-value formulas published by the Consumer Financial Protection Bureau and the Federal Reserve. The methodology block below shows every variable and rounding step we apply, so the answer is never a black box.

Every calculation happens in your browser with JavaScript — your income, balances, and loan numbers are never sent to our servers, logged, or shared. Close the tab and the inputs vanish. No sign-up, no tracking pixels on the form, no spreadsheet emailed to you later.

lightbulb Pro tip

Save the URL after you calculate — your inputs aren't stored, so write down the headline number plus the breakdown. Then come back and edit one variable at a time (down payment, rate, term) to see exactly which lever moves your monthly figure the most. That's where the real planning happens.

Formula & methodology

Formula: Net pay = gross pay − taxes − deductions

A paycheck estimate starts with gross wages for the pay period, subtracts pre-tax deductions, applies payroll taxes and withholding rules, then subtracts post-tax deductions.
