Free Tools

Free Tools is the set of options calculators published at optionspro.com/tools. Like the Academy, it sits outside the app: no account, no sign-in, no Pro subscription, and no usage cap.

The tools run entirely in your browser. Nothing you type into one is sent to or stored on our servers, which is also why none of them can see your trades - the in-app versions are where your own positions come in.

Your work isn't lost the moment you blink, though. The profit calculator keeps the position you're building in the browser tab you're using, so a refresh mid-edit picks up where you left off; closing the tab clears it, and another tab or device never sees it. It also opens straight into a position encoded in a shared ?p= link, which is what its Share button copies to your clipboard. The covered call calculator keeps nothing and starts fresh each visit.

What's there

Options Profit Calculator

optionspro.com/tools/profit-calculator

Build a structure leg by leg - up to 8 legs - and see its payoff diagram, max profit, max loss, break-evens, Greeks, and a modeled probability of profit.

Beyond what the in-app calculator does, this version adds:

• Strategy presets - 18 named structures (verticals, iron condor, iron butterfly, calendar, straddle, strangle, covered call, cash-secured put and more) that fill the legs in for you, so you can start from a shape rather than from an empty form.
• A position sizer - how many contracts a given account size and risk tolerance support.
• An IV crush panel - what the position is worth if implied volatility collapses after an event.
• A Greeks profile chart - how each Greek moves across underlying prices, rather than just its value at one price.
• A scenario matrix - P&L across a grid of underlying prices and dates.
• Shareable position links - the whole structure is encoded in the URL, so you can send someone exactly what you're looking at.

Covered Call Calculator

optionspro.com/tools/covered-call-calculator

Built around shares you already hold rather than a structure you assemble. Enter your share price, cost basis, contract count, strike, days to expiry and any dividends due before expiration, and it returns:

• Premium income, and the return if unchanged and if called away, both annualized.
• Your break-even and the downside cushion below it.
• Assignment odds and the chance of touching the strike before expiry.
• Income yield and the net cost basis the premium leaves you with.
• The price above which simply holding the shares would have paid more than writing the call.

It also warns that an in-the-money call on a dividend payer can be exercised early - typically the day before the ex-dividend date.

When to use the in-app versions instead

Once you're signed in, the versions inside OptionsPro are the better tools for anything involving a position you actually hold:

See Profit Calculator for the in-app tool, including the Pro side panel that opens it from any page.

How it fits with the rest of the site

• These docs cover the product. Start at Getting Started.
• OptionsPro Academy teaches options themselves, and its Put into practice buttons send you to these tools to try the math on a lesson's worked example.
• The free tools are the calculators with nothing to sign up for.

None of the three requires a subscription. See Subscription for what Pro adds inside the app.
