Cash-Secured Put Tool

Price the put before the put prices you.

Use your own numbers to check breakeven, cash required, assignment size, premium return, and the warning signs that can hide behind a rich quote.

Inputs

Use the same numbers you would use before opening risk.

This is a hand-entry calculator. It does not pull live option chains and does not store anything on Miss Lemon servers.

Risk ticket

SPY short put math

The return may be compensation for a real pressure point. Keep the trade small enough to remain optional.

Miss Lemon warning
  • One contract group uses more than half of the cash balance. Assignment could crowd out future choices.

Boundary

This page frames risk. It does not choose a trade.

Miss Lemon can compare cash, assignment size, and premium math. The underlying, timing, liquidity, and final decision still belong to the user.
