Is this scenario basically correct about a stock call option?

A stock is currently trading at $7.28
A call option with $7.50 strike is .75

.75 x 100 = $75 + $14 (approx comm) = $89 cost for the option

In order to break even...
$89 option cost / 100 = .89 + the $7.50 strike = $8.39 (PPS has to hit)

8.39 - 7.28 / 7.28 = 15.3%
So the pps would have to increase 15.3% (within the contract time) just to break even on the $7.50 option that cost $89?
That seems a little steep.
Am I missing something?
