The trade
Option type
How will you exit the trade?
Use the premium you can actually sell for, usually the bid. The mid price is not a fill. Call or put does not change this result: early-sale profit is only the change in premium.
At expiration the contract is worth only its intrinsic value. Time value is gone. If it finishes in the money, the broker can auto-exercise it into shares. That share position is outside this calculator.
Result
Approximate only. Set this to the pounds you actually receive for each dollar after conversion. It is not a live rate, and it is stored only on this device.
