Frequently asked questions about our financial calculators

Are the financial calculators free to use?

Yes. Every financial calculator on CalcCentral is 100% free, with no signup, no account, and no hidden fees.

How accurate are these financial calculators?

We use industry-standard formulas - amortization, compound interest, IRR, and the 2025 IRS tax brackets - and cross-check results against real loan and tax scenarios. For exact figures (especially tax), always confirm with a CPA.

Do you store my financial data?

No. All calculations run client-side in your browser. We do not see, log, or store salaries, balances, or any values you enter.

What tax year does the income tax calculator use?

Our income tax calculator uses 2025 federal brackets and the most common US state brackets. We update each January for the new filing year.

Can these calculators help me get pre-approved for a mortgage?

They give you a realistic estimate of your monthly payment, DTI ratio, and what you can afford - useful before you talk to a lender. Pre-approval itself requires a hard credit pull by the lender.
