a finance lab · by virtueneuro

The lab shows its work.

Bonds, the time value of money and discounted cash flow — computed, then explained. Every screen prints the formula it evaluated and names the lecture it came from, so you can check it rather than trust it.

Bond Lab showing a clean price of 1,015.74, the pricing formula, and an exhibit plotting price against yield where the straight duration line pulls away from the exact curve.

Bond Lab

Price and yield to maturity, then duration and convexity — and the exhibit that shows you exactly where duration alone stops telling the truth.

MIT FMF 2 · DM 3

The time-value-of-money lab showing a level payment of 1,266.71 and an exhibit where interest and principal cross in month 176 of 360.

Time Value of Money

Annuities, the level payment and the full amortization schedule, with NPV and IRR — including the month your loan finally turns the corner.

MIT FMF 3–4

The DCF engine showing an enterprise value of 1,405 and an exhibit where value against the discount rate steepens towards a vertical asymptote.

DCF Engine

Free cash flow to the firm, WACC, terminal value and the equity bridge — with a sensitivity grid that shows how fragile a single valuation really is.

MIT FMF 17 · Koller 10–15

Built to be checked, not believed

Most calculators hand you a number and stop. hedqe prints the formula it evaluated, cites the lecture it comes from, and draws an exhibit with a caption explaining what the curve actually means — why convexity matters at 200 basis points but not at 25, why a DCF near its terminal-growth asymptote should never be quoted as one number.

The mathematics is bundled with the app rather than fetched, so every lab works with the network off — on the bus, in an exam room, anywhere. Nothing you type is sent anywhere, because there is nowhere for it to go.

It is free, and it stays free. No account, no trial, no upgrade screen.
