Finance, taught properly.
From first principles to Finite Differences.

A complete curriculum built from two decades of trading-floor practice and university teaching: five levels from the time value of money to multicurve pricing and quantitative miniatures, with rigorous mathematics, interactive dashboards and graded exercises. Your progress is saved in this browser, and with a free account it follows you across devices.

Free while we build

FinAcademy is free during the founding period. Paid tiers will come later, and founding members will keep meaningful benefits. A free account adds synced progress, verifiable certificates for passed module tests, and a fortnightly interactive-problem newsletter.

How it works

Rigorous theory

Every result is stated precisely and typeset in real mathematics, with the market conventions (day counts, compounding bases) that textbooks skip.

Interactive dashboards

Sliders, charts and amortization tables let you develop intuition by moving the inputs yourself instead of staring at static slides.

Graded exercises

Numeric and multiple-choice problems with instant feedback and full worked solutions. Solved exercises and completed lessons are tracked per browser.
