We teach corporate finance the way we wish it had been taught to us
Corporate Finance Fundamentals started from a familiar frustration: most finance content online is either a two-paragraph definition or a graduate textbook with nothing in between. Real learners need a middle layer — complete lessons in plain English, worked numbers they can trust, and tools that turn abstract formulas into something you can push and pull with your hands.
That middle layer is what we build here. Every topic is written as a full guide, not a summary; every formula is demonstrated on real numbers; every calculator shows its interpretation, not just its output; and every article ends by handing you the tool that lets you re-run the argument yourself.

What you will find here
Five learning tracks — Core Finance, Valuation, Capital Budgeting, Risk & Return, and Capital Structure & Policy — each with a landing page, sequenced guides, and practice links.
Browse the tracks
Nine calculators: time value of money, NPV & IRR, DCF valuation, bond pricing, WACC, ratio analysis, DuPont, cash conversion cycle, and break-even — each with interpretation built in.
Open calculators
Four interactive visual tools: NPV profile with IRR marker, compound growth, capital structure WACC curve, and loan amortization — sliders instead of spreadsheets.
Open visual tools
Long-form, illustrated articles that connect the concepts across tracks and end with the exact calculator to practise on.

How we write
Depth over summaries
Every guide is a complete lesson — definitions, formulas with real markup, worked examples, and the failure modes — not a flashcard. If a topic deserves five minutes, we write the version that earns them.
Practice is non-negotiable
Concepts stick when numbers move. That is why every track is wired to calculators and simulators, and every article points to the exact tool where you can replay its examples.
Honest about limits
We teach simplified, standard textbook models and we say so. Nothing here is investment advice; every page that could be mistaken for one links to the Disclaimer instead of pretending otherwise.
Free, no gates
All guides, calculators, tools, and articles are free and ungated. Learning finance should not begin with a paywall, a signup form, or an email you will regret giving away.
