Editorial Policy

Last updated: 5th March 2026

CalcTypes is committed to creating calculators that are simple, fast, and as accurate as possible.

How we create and review calculators

We follow a consistent process:

  1. Formula selection: We use standard formulas and widely accepted calculation methods.
  2. Rule/rate verification (when applicable): For calculators that rely on rules or rates (such as taxes), we reference official sources when possible and note the date of verification.
  3. Testing: We test calculators using worked examples and edge‑case inputs (e.g., zero values, minimum tenures, large values).
  4. Transparency: Each calculator includes assumptions and methodology notes where relevant.

Corrections

If you find an issue, contact us with:

  • the calculator name
  • the inputs used
  • the result shown
  • the result you expected (and why)

We review reports and publish corrections when needed.

Independence

Any advertising or affiliate relationships (when enabled) do not affect how we design our calculators.

Updates

We periodically review calculators and update them when we verify changes in rules, rates, or methodology.
