Economics Formula Verification

40 of the 40 published economics calculators have an automated formula test suite. Each row gives one calculator's passing cases and the kinds of check behind them.

Last updated 16 September 2026

This is the economics section of the formula verification report, which explains what each kind of case tests, how the counts are produced and what they do not prove. Rows run from the largest suite to the smallest; each row's address ends in the calculator's slug, so one calculator's evidence can be linked and cited on its own. The test file behind every row, and the per-kind numbers, are in the machine-readable report.

Every economics calculator, with its case mix
