Free, accurate calculators for property tax, debt payoff, retirement planning, and other personal finance decisions. No sign-up required.
Personal finance decisions compound. A 1% difference in your assumed retirement return swings your FIRE number by tens of thousands of dollars. Choosing avalanche over snowball on your debt payoff can save you hundreds in interest. Knowing your true property tax burden before you buy a home prevents budget surprises that strain household finances for years.
Our finance calculators cut through the marketing noise from banks, brokers, and agents — and give you the same numbers a financial planner would run, instantly and for free.
Our property tax calculator is the most comprehensive on the site, with dedicated pages for every U.S. state and the District of Columbia. Each state page uses 2024 U.S. Census Bureau effective tax rate data, accounts for state-specific exemptions (homestead, senior, disabled veteran), and gives you both annual and monthly estimates.
The FIRE (Financial Independence, Retire Early) movement uses a simple rule: you need 25 times your annual expenses invested to safely retire. Our calculator lets you adjust the safe withdrawal rate, factor in expected inflation, and stress-test your number against different market scenarios.
Two competing strategies dominate debt payoff advice: avalanche (highest interest rate first, mathematically optimal) and snowball (smallest balance first, psychologically rewarding). Our calculator runs both simultaneously and shows you exactly how much extra interest the snowball method costs you — so you can make the trade-off with eyes open.
