The Options Bench exists to build the options calculators that bigger sites skip — scenario-specific, practitioner-grade tools for the strategies retail traders actually run. Covered calls, cash-secured puts, the wheel, rolling decisions: each gets a calculator that handles the awkward edge cases instead of pretending they do not exist.
Every tool is free, runs entirely in your browser, requires no signup, and shows no paywall. The site is funded by advertising so the calculators can stay open to everyone.
Who builds this
Theo Chen · Founder, The Options Bench
I've traded options as a retail trader out of Asia for over a decade — through a few full market cycles, a handful of painful assignments, and more rolled positions than I'd care to count. My day-to-day is income strategies: covered calls, cash-secured puts, the wheel, and the occasional spread, managed around days-to-expiration and the Greeks rather than gut feel.
The Options Bench started from a simple frustration. Most options calculators are built to rank in search engines, not to answer the question a trader actually has before placing an order. They gloss over the edge cases — in-the-money covered calls, zero-DTE math, what your cost basis really becomes after assignment. So I build the tools I wanted myself: small, fast, free, and correct on the awkward cases.
I'm not a financial advisor, and nothing here is advice. I'm a trader who codes, sharing the same math I use to size up my own positions.

The calculators are educational tools to help you understand the math of a position before you trade it.
