Educational estimates only

PlainCalc provides calculators and explanatory content for general information and education. Nothing on this site is financial, investment, tax, legal, or accounting advice, and nothing here creates a professional-client relationship. We are not a bank, lender, broker, tax preparer, or registered investment adviser.

Results are estimates

Every result depends on the numbers you enter and on simplifying assumptions that are stated on each page (for example: the standard deduction, a representative state tax rate, a fixed interest rate, monthly compounding). Your lender, employer, payroll provider, or tax software may calculate differently. Before making a decision that involves real money, confirm the figures with the institution involved or a licensed professional.

Data sources and currency

Reference data (federal tax brackets, standard deductions, Social Security wage base, retirement contribution limits, state income and sales tax rates, average mortgage rates) is taken from official sources: the IRS, the Social Security Administration, state departments of revenue, the Tax Foundation, and Freddie Mac via FRED. The year the data was verified is shown on the relevant pages. Rates and laws change; we update on a regular schedule but cannot guarantee that every figure is current at the moment you use it.

No guarantees

The site is provided “as is”. We make no warranties about accuracy, completeness, or fitness for a particular purpose, and we are not liable for decisions made or actions taken in reliance on the site. See the Terms of use for the full limitation of liability.

Advertising

The site is supported by advertising served by Google AdSense. Advertisements are clearly distinguishable from content, are never placed inside calculators, and never affect calculation results. We do not accept payment to recommend any financial product, and we do not publish sponsored content presented as editorial.

Questions or corrections

If a figure looks wrong, please tell us. Confirmed errors are corrected promptly and noted on the page.
