The calculators behind our apps.
Free, in your browser.

Every one of these runs entirely on your own device. Nothing you type is sent to a server, stored, or logged — there is no account and no upload. They are the same calculations our desktop and mobile apps run, carved out one at a time so you can use them without installing anything.

Why we give these away

ProDesk builds four professional-grade applications: RiskDesk for trade risk management, OptionsDesk for options analysis, HedgeDesk for AI-assisted equity research and hedging, and CashDesk for the tax, budgeting and invoicing problems that come with irregular income.

Each app contains dozens of calculations. A few of them answer a single, self-contained question that does not need an install, a portfolio, or a login — how big should this position be, where does this option break even, how much of my portfolio's market exposure is actually hedged, what do I need to charge an hour. Those are the ones published here. They are complete, not crippled trials: no result is withheld, no field is locked.

What these tools will not do

They do not fetch live prices, so you supply the numbers. They do not remember anything between visits. And they do not tell you what to trade, buy, sell or claim — they do arithmetic on inputs you choose, which means the quality of the output depends entirely on the honesty of the input. None of it is financial, investment, tax or legal advice.
