Every calculator, guide, and explanation on mCalculator follows the same process: research the standard formula, verify it against primary sources, document the assumptions, and re-check the page on a fixed schedule.
mCalculator is produced by a small editorial team that builds and maintains consumer-finance calculators. We are not lenders, brokers, financial advisers, or tax preparers, and we do not hold ourselves out as licensed professionals. What we do is narrow and specific: implement the standard math behind everyday money decisions, explain it in plain English, and show our work.
Because we don't claim professional credentials, we compensate with transparency. Every calculator ships with its formula, a worked example, and a written list of the assumptions and limitations behind the result — see our calculation methodology. If a page can't explain how it reached a number, it doesn't ship.
When a page states a rule, limit, or threshold, we prefer primary sources: government agencies and regulators, the loan program's own documentation, and published standard formulas. Where numbers vary by lender, state, or product, we say so instead of presenting one figure as universal.
We do not publish:
mCalculator is free to use and supported by display advertising. Advertisers have no input into which calculators we build, what our guides say, or how a result is presented. Ad slots are labelled and kept visually separate from calculator output, and no calculator result is ever influenced by an advertiser relationship.
If we ever add affiliate or partner links, they will be disclosed clearly on the page where they appear, and they will not change the underlying math or the ordering of editorial recommendations.
Two optional features on the site call an AI model: the natural-language calculator finder on the homepage, and the "Explain this result" button on calculator pages. Both are opt-in actions that you trigger by clicking, and neither one performs the calculation — the numbers always come from our own deterministic formulas.
AI is not used to write published guides or methodology pages unattended. Where AI assists with drafting, a human editor verifies every factual claim and every number before publication, using the same fact-check step described above.
We fix errors quickly and visibly. If a formula, example, or factual claim is wrong, we correct the page and update its "last reviewed" date. Substantive corrections that change a result are noted on the page itself rather than silently edited.

Our tools are educational estimates. They cannot see your credit profile, your lender's pricing, your local taxes and insurance, or your full financial picture, so results will differ from a real quote. Nothing on this site is financial, tax, or legal advice — see our financial disclaimer for the full statement.

This calculator is for educational and estimation purposes only. It does not provide financial, mortgage, tax, investment, or legal advice. Actual rates, payments, taxes, fees, insurance costs, eligibility, and loan terms vary by lender, location, credit profile, and market conditions. Always compare official offers and consult a qualified professional before making financial decisions.
