What your free week unlocks

OpCalc doesn't lock features away — it strips the advertising out of the tools you already use, so the numbers are the only thing on the screen.

  • Strategy calculators, uninterrupted

    Every calculator — from a long call to an iron condor or a custom 8-leg position — with the payoff table and profit/loss chart clean and full size. Tweak strikes, dates and volatility and compare scenarios back to back without an ad reloading the page underneath you.

  • Option Finder without the clutter

    Screen for the trades that fit your outlook and read the results full width, with more candidates visible at once and nothing competing for attention while you sort and compare what the screener turns up.

  • Detailed option chain analysis

    Work through strikes, expirations, bid/ask and implied volatility in dense tables that stay readable, without an ad slot breaking up the rows or pushing the columns you're scanning below the fold.

  • A completely ad-free experience

    No banners, no sidebar units, no pop-ups and no video that starts playing while you're mid-calculation. Pages load faster, nothing shifts under your cursor as an ad renders, and on a phone or tablet the full width of the screen goes to your strategy instead of to advertising.

Your subscription keeps this site going

We've run Options Profit Calculator since 2008 and the calculators have been free the whole time — no paywall, no locked strategies, no account required to run a payoff diagram. Advertising is what has paid for that.

OpCalc is how traders who'd rather not see ads can support the site directly. It's a small independent team, so every subscription goes straight back into development: faster data, better charts and the new tools option traders keep asking us for. The more support we get, the more we can build.

You're in good company

OpCalc is used every trading day by independent retail traders and by professionals at banks, hedge funds, prop desks and advisory firms who reach for it to sanity-check a structure quickly.

Eighteen years of traders have run their positions through these calculators before putting real money on them.
