Frequently Asked Questions
Are these finance calculators free?▾
Yes. All calculators are free, with no signup, no email required, and no daily limits. Most run 100% in your browser — your numbers never leave your device.
Are the calculators accurate?▾
They use industry-standard formulas (e.g., the standard mortgage amortization equation, 2026 IRS federal brackets, current FICA rates). They're for educational estimates, not professional tax/financial advice — talk to a CPA or financial advisor for binding decisions.
Why are some results different from my bank's calculator?▾
Banks add their own fee schedules, processing costs, and underwriting adjustments. Our calculators show the math directly so you can compare different scenarios apples-to-apples without a sales pitch.
Do these work for non-US users?▾
Many calculators (compound interest, tip, percentage, salary conversion) work anywhere. Tax-related ones (paycheck, crypto tax, mortgage) use US tax rules and US state data — the formulas may not apply abroad.
How often are tax brackets updated?▾
We update federal and state brackets annually after the IRS publishes inflation-adjusted figures (typically in November). The current calculator uses 2026 brackets.
