Frequently Asked Questions
Are these calculators really free?
Yes! 100% free, no sign-up required, no credit card, no hidden fees. We believe financial tools should be accessible to everyone.
Do I need to create an account?
Nope! Just visit any calculator and start using it immediately. No registration, no email required.
How accurate are these calculators?
We use the same standard formulas lenders and financial planners use: loan amortization for mortgages and car loans, compound interest for investments, and current federal tax brackets and FICA rates for paychecks. Results are estimates, because your actual rate, fees, and taxes depend on your lender, state, and personal situation.
Can I use these for actual financial decisions?
Our calculators provide accurate estimates for planning purposes. For major decisions (mortgages, investments), consult with licensed professionals. We're a planning tool, not financial advice.
Do you save my data?
No. Calculations happen in your browser, and we don't store the numbers you enter. Like most websites, we use Google Analytics and Google AdSense cookies. See our Privacy Policy for details.
