About SimpleCalc
Last updated: July 30, 2026
Clear calculations for real decisions
SimpleCalc provides focused financial, math, conversion, and everyday calculators for a global English-speaking audience. Each tool is designed to make its inputs, results, assumptions, and limitations understandable without requiring an account.
Accuracy before coverage
We only publish calculators when the formula and edge cases can be defined clearly and covered by automated tests. We deliberately defer topics—such as health, tax, and region-specific retirement calculations—when a generic result could be misleading.
How calculations are reviewed
Numerical logic is kept separate from the interface as testable functions. Representative examples, zero-value behavior, invalid inputs, and important boundaries are checked before release. Financial tools state their simplifying assumptions and should be treated as educational estimates, not professional advice. Read the full calculation methodology.
Privacy by architecture
Calculations run locally in the browser. SimpleCalc currently has no account system, application database, analytics script, or advertising tracker, and calculator entries are not sent to a SimpleCalc server.
Corrections
If a formula, explanation, or result appears incorrect, contact [email protected] with the calculator name, inputs used, expected result, and a reliable reference when available.
