About PureCalculator

Our Engineering Standard

PureCalculator exists to replace cluttered, ad-heavy utility pages with a fast, verifiable calculation ledger. Whether you are stress-testing a home refinance, planning a retirement drawdown timeline, auditing effective tax brackets, or checking macro targets, our tools pair clean typography with documented mathematical assumptions.

How We Audit Formulas

• Financial Modeling: Loan amortization, APR compounding, IRR, NPV, and tax estimation routines are checked against standard institutional banking conventions.
• Biometric & Clinical Equations: Energy expenditure, body composition, and circadian sleep cycle modules reference established frameworks including Mifflin-St Jeor, Harris-Benedict, Boer, and U.S. Navy anthropometric formulas.
• Applied Math & Everyday Utilities: Symbolic precision, statistical distributions, geometry solvers, and everyday unit conversions undergo automated test-vector checks before release.

Independent & Ad-Light

We do not sell user inputs to lead brokers or mortgage aggregators. Your financial plans and health numbers remain yours.
