economics.horse Makes Money Math Less Opaque

Field notes

The calculator suite is organized into four visible groups: saving and investing, everyday money, business basics, and Economics 101. Its examples expose assumptions rather than presenting unexplained totals: the compound-interest illustration uses a $5,000 starting amount, $200 monthly deposits, 7% nominal annual interest, monthly compounding, and 10-, 20-, and 30-year horizons. The interface also includes search, favorites, and saved scenarios.
