Risk disclaimer

This calculator provides a gross single-settlement estimate, not investment advice. A covered call still carries downside like holding the asset itself.

What is a covered call?

Hold spot and sell the same amount of calls: below the strike you keep the coin and the premium; above the strike your coin is assigned away and gains cap.

This estimates gross expiry PnL on a single settlement, ignoring fees, taxes and rolling.

How to use

  1. Enter your spot cost basis.
  2. Enter the premium received, strike and expected expiry price.
  3. Click Calculate to see expiry PnL, break-even and worst-case loss.

Formula

  • Expiry ≤ Strike: PnL = (Expiry − Cost) + Premium
  • Expiry > Strike: PnL = (Strike − Cost) + Premium
  • Break-even = Cost − Premium

Example

Cost 100, premium 5, strike 110: expiry 120 → PnL = (110−100)+5 = 15; expiry 90 → −5.

Break-even = 95, so you only lose below 95.

FAQ

What about capped upside?

That is the trade-off of selling the call: you earn premium but give up gains above the strike.

Want to keep upside?

Raise the strike (lower premium) or consider variants; protective puts address downside differently.
