Plain English
Three things to know about price and P/L:
You just travel along the shape. Moving the stock slides you up or down a fixed payoff line.
The floor never moves. However far the stock falls, a long call flattens onto its capped loss, the premium.
Leverage is the slope. Past breakeven the line climbs faster than the stock itself, which is the whole point of a call.
Taxes are not shown here. Options and the underlying stock are taxed differently, and it depends on your holding period and account type. None of this is tax advice.
