# How do I calculate option payoff before its expiration date? [closed]

How do I calculate option payoff before its expiration date? For example, if I long a 6 month call with K = 11100, T = 0.5, p = 150, what would be the payoff of the option if I exercise it in 3 months time and if the spot price is 11300.?

If you exercise the option (assuming that is an american option) you would receive the intrinsic value, which is for a Call option $$\max(S-K, 0)$$, and for a Put option $$\max(K-S, 0)$$. Hence, 11300.00 - 11100.00 = 200.
