About Loan Lyze
Financial math should be easier to inspect.
Loan Lyze is an independent calculator library built to help people understand financial tradeoffs before making a decision.
What we publish
The library covers borrowing, mortgages, home equity, debt, student loans, tax, payroll, business, real estate, insurance, retirement, and investing. Each tool pairs interactive math with its calculation method, scope, limitations, source direction, and related research paths.
Our promise
We aim to show the assumptions, explain the calculation in plain language, identify material exclusions, and direct users to authoritative sources. A precise-looking result is not necessarily a certain outcome, so the site distinguishes arithmetic from approval, eligibility, underwriting, tax filing, professional advice, and forecasts.
Editorial independence
Calculator explanations are designed to remain useful without an advertisement, referral, application, or account. The site does not represent a lender, broker, insurer, tax authority, government benefit program, or investment adviser. Named author or reviewer credentials are displayed only when that person has actually participated and approved their attribution.
