About USFinWise
Free, accurate, and private financial calculators built for Americans.
🎯 Our Mission
USFinWise was built with one goal: give every American access to the same high-quality financial tools that used to be reserved for people who could afford a financial advisor. Whether you're a first-time homebuyer trying to understand your mortgage payment, a young professional planning for retirement, or someone trying to get out of credit card debt — we built this for you.
All five calculators on USFinWise are completely free, require no account or sign-up, and process all your data locally in your browser. We never see your numbers. We never store them. Your financial information stays yours.
🧮 What We Offer
Calculate your full monthly PITI payment including principal, interest, property taxes, homeowner's insurance, HOA fees, and PMI. See a complete amortization schedule and understand exactly how much of your payment goes to interest vs. principal each month.
Project your retirement nest egg with employer match, compound growth, and 2026 IRS contribution limits built in. See how inflation affects your purchasing power and estimate your monthly withdrawal using the proven 4% rule.
Find your true monthly car payment including trade-in value, sales tax, and dealer fees — costs that dealers often hide until you're sitting at the finance desk. Know your numbers before you walk in.
See your exact debt-free date and how much interest you save by paying more than the minimum. With average US credit card APRs near 27% in 2026, this calculator could save you thousands of dollars.
Visualize the exponential power of compound interest over time. Support for daily, monthly, quarterly, and annual compounding. Includes the Rule of 72 to instantly calculate how long it takes your money to double.
