About

Calc My Net Worth is a set of free calculators for common US personal finance questions — take-home pay and self-employment tax, rent vs. buy and other home-buying decisions, net worth, retirement income and early withdrawals, and debt payoff. Every calculator runs entirely in your browser: nothing you type into a tool is sent to us or stored anywhere.

Our approach to accuracy

Every figure — federal tax brackets, FICA rates, state tax rates, property tax and insurance defaults, the 4% withdrawal-rate rule, net worth benchmarks — is sourced directly from the primary government or institutional publication (IRS, Social Security Administration, Federal Reserve, Tax Foundation, and similar), not from a secondary blog restating someone else's numbers. Every tool page has a visible “Sources” section linking to exactly where each number came from, so you can verify it yourself rather than take our word for it.

Where a calculator simplifies something for clarity — for example, using a statewide average instead of a metro-specific rate — that simplification is disclosed directly on the tool, not hidden in fine print.

Not financial advice

These tools produce estimates to help you understand a calculation, not personalized financial, tax, or legal advice. For decisions specific to your situation, talk to a qualified professional.

Who's behind this

Calc My Net Worth is built and maintained independently. Spotted an error in a formula? Check the Sources link on the relevant tool for where the figure comes from.

Verification and corrections

The independent operator develops and maintains these tools from published sources. This is not a financial advisory or tax practice, and we do not claim that every page is reviewed by a licensed professional.

Calculation changes are checked with automated tests against official examples, independent arithmetic and boundary cases. Before publication we check the build, internal links, page metadata and visible caveats. Tests check the modeled rules; they cannot make a simplified estimate complete for every household. Rates, data years and exclusions are identified on each tool.

Report suspected errors through Contact, with the page URL, the disputed passage or result, and an official source if available. Use fictional input examples; do not send tax returns, account numbers or identity documents. Verified errors are corrected in the calculation or text and related explanations.
