Strike price

Also called: exercise price, grant price

In one line

The fixed price you pay per share to exercise an option, set at the share's fair market value on the day the option was granted.

In plain English

It's the 'buy price' baked into your option. Your paper gain is roughly today's share value minus your strike price, times how many shares you hold.

If you were explaining it to a 5-year-old

It's the price written on your toy voucher — the number of coins you must pay to claim the toy, no matter how expensive the toy becomes.

Why it matters when you sell

A low strike versus today's value means a bigger gain when you sell — but also a bigger taxable spread when you exercise. It drives both your upside and your tax bill.
