What the cash-secured put calculator shows you
A cash-secured put is a trade where you sell a put option and hold enough cash in your account to buy 100 shares if assigned. The cash-secured put calculator breaks down the whole trade:
- Premium collected — the cash you receive for selling the put.
- Cash collateral required — strike × 100 minus premium. This is what gets tied up until expiration or assignment.
- Break-even price — strike minus premium. The stock can drop to this price before you start losing money.
- Yield on cash — premium ÷ collateral, shown as a percentage.
- Annualized return — the cash-secured put calculator re-bases short-dated premium to a 365-day yield.
- Probability of assignment — derived from the put's delta.

- Pick a target delta. 0.20–0.30 is the sweet spot for most cash-secured put sellers. The cash-secured put calculator highlights those strikes automatically.
- Choose expiration. Weeklies for higher frequency income, 30–45 DTE for balance, LEAPS for set-and-forget.

A DIY cash-secured put calculator in Excel works for one trade at a time, but it breaks the moment you want to (a) compare 20 strikes across 5 tickers, (b) screen the whole market for the best annualized yield at 0.25 delta, or (c) factor in upcoming earnings or ex-dividend dates. Our cash-secured put calculator handles all three automatically, pulls live option chain data, and shows the annualized yield across weekly / monthly / LEAPS in a single table.

Cash-Secured Put Calculator FAQ
What is a cash-secured put calculator?
A cash-secured put calculator shows everything you need to evaluate a cash-secured put trade: premium received, break-even price, cash collateral required, yield on cash, and annualized return. Enter the ticker, strike, and expiration — the cash-secured put calculator does the rest in under a second.
How is the cash-secured put calculator different from a covered call calculator?
A covered call calculator prices a call sold against 100 shares you already own. A cash-secured put calculator prices a put sold against cash collateral — you don't own the stock yet, you're agreeing to buy 100 shares at the strike price if assigned. Both are neutral-to-bullish income strategies, and the wheel strategy alternates between them.
How much cash do I need for a cash-secured put?
Strike × 100 shares minus the premium collected. The cash-secured put calculator shows this automatically. For a $50 strike on any ticker you need $5,000 in cash collateral (minus premium). This is why "cash-secured" puts are considered safer than naked puts — the brokerage reserves the full assignment amount.
What delta should I target in the cash-secured put calculator?
Most cash-secured put sellers target a delta of 0.20–0.30 (roughly 20–30% assignment probability). The cash-secured put calculator surfaces those strikes automatically and shows the trade-off between premium and assignment risk. Aggressive sellers go 0.35–0.45 delta for higher premium; conservative sellers stay below 0.20.
How does the cash-secured put calculator handle weekly options?
It annualizes every trade, so a 7-day weekly cash-secured put and a 45-day monthly cash-secured put show up on the same scale. Weeklies tend to have higher annualized yields but much higher time commitment (roll every week).
Can I use the cash-secured put calculator in an IRA?
Yes — cash-secured puts are one of the few short-premium strategies allowed in most IRAs because they're fully collateralized. The calculator works the same way in an IRA; just confirm your broker's specific permissions (Schwab, Fidelity, and IBKR all permit CSPs in IRAs with Level 2 options approval).
What's the break-even on a cash-secured put?
Strike price minus premium received. If your strike is $50 and you collected $1.50 premium, your break-even is $48.50 — the stock can fall to $48.50 before you start losing money on assignment. The cash-secured put calculator shows this in real-time as you change strikes.
