Our review process
Before any calculator goes live, our reviewers check: (1) the underlying formula against published research or official data sources, (2) the input ranges and edge cases for accuracy, (3) the output values against manually calculated benchmarks, and (4) the FAQ answers for scientific accuracy. Calculators are re-reviewed whenever source data is updated.
