About MoneyMath

MoneyMath is an independent personal finance calculator suite. No accounts, no email capture, no lead generation, no affiliate recommendations sneaking into the answers.

What we are

We're a small site built by an engineer who got tired of mortgage and loan calculator pages that buried the math under five popups, an email signup, and a “get matched with a lender” button. Every page on MoneyMath shows the formula, a worked example, and a plain disclaimer. That's the whole product.

What we are not

We are not licensed financial advisors. We are not a brokerage, lender, bank, tax preparer, or estate planner. We do not provide personalized recommendations. The calculators on this site produce mathematical estimates based on the inputs you provide. Real-world quotes, tax treatments, fees, and lender margin will produce different numbers.

How we make money

MoneyMath is supported by display advertising (Google AdSense). Ads are labeled and never influence the math or the explanations. We do not accept paid placements, affiliate commissions, or sponsored calculators.

Privacy

We don't ask for your name, email, or any personal information. Inputs you type into a calculator stay in your browser — we don't send them to a server. Standard third-party analytics and ad-serving cookies apply — see our privacy policy for details.
