Accuracy Policy
How CalcVo validates calculator accuracy with unit tests, edge cases, and deterministic client-side math.
Last updated: July 13, 2026
CalcVo is built for trustworthy results. We validate calculator accuracy through automated tests, documented formulas, and transparent methodology.
How we verify accuracy
- Unit tests for every engine module (money, health, GPA, percentage, date)
- Edge case coverage: zero values, leap years, boundary BMI categories
- Cross-checks against published formulas and reference calculators
- End-to-end Playwright tests for critical user flows
Known limitations
- Results are estimates — not tax, legal, or medical advice
- PMI, property tax, and insurance are user-provided or estimated
- Business day counting excludes public holidays in v1
- GPA conversion formulas vary by institution — verify with your school
