@vwman111 - I posted this in another thread, but it seems it may be useful for you as well:
Basic call options courses have a 'breakeven' -- the point at which you would breakeven compared to not investing at all. But for our purposes, I'm wondering if it makes more sense to look at a 'call to stock breakeven' instead, which is the point where buying a call becomes equivalent to buying the underlying stock instead. I created a rudimentary calculator for that... it will help you to compare when (and by how much) a call becomes more worth it to purchase when compared to the stock itself. Feel free to make a copy of it and play around with the highlighted cells to get a better understanding of how much you expect a stock to go up by the call expiration date to determine if it's more worth it to buy a call, or just buy the stock:

Here's an example using a TSLA January 2022 $800 call option:

So if you bought the call option, the stock would have to be at $1175.65 or above at expiration for you to make more money by buying the call option when compared to buying an equivalent amount of stock with the $25,818 initially. If the stock price is at $1500 in January 2022, you will have made twice as much money by buying the call instead of the stock ($44,182 vs $22,110.86 profit)
That's a cool calculator!
I personally am able to do it in my head very easily, knowing that an option is always worth between 0 and 100 shares.
At expiration, an option is always worth 100 shares minus the number of shares it costs to exercise:
Stock Price: $1,000
- An option with a $500 strike price will be worth 100 shares minus the $500 * 100 = $50,000 = 50 shares it costs to exercise. Therefore, this option is worth 100 - 50 = 50 shares.
- An option with a $800 strike price will be worth 100 shares minus the $800 * 100 = $80,000 = 80 shares it costs to exercise. Therefore, this option is worth 100 - 80 = 20 shares.
- An option with a $250 strike price will be worth 100 shares minus the $250 * 100 = $25,000 = 25 shares it costs to exercise. Therefore, this option is worth 100 - 25 = 75 shares.
