Stock-Based Compensation

How pay in shares is measured and expensed, why it's so often left out of the numbers companies highlight, and how to count what it costs shareholders.

Lesson 6 of 8 · 6 min read · Advanced · Members · Last reviewed October 2026

The short version

When a company pays employees in shares or options, accounting rules treat it as an expense, measured at the award's value on the day it's granted and spread over the years the employee has to stay to earn it. No cash leaves, so the cash flow statement adds it back, and many companies also remove it from the adjusted profit they highlight. The cost doesn't disappear. Existing shareholders pay it through dilution, or the company spends cash on buybacks to cancel the dilution out. To judge it, look at the expense as a share of revenue, the change in the share count over several years, and free cash flow after subtracting it.

By the end of this lesson, you'll be able to

  • Explain how stock-based compensation is measured and when it's expensed
  • Trace where it appears in each financial statement
  • Estimate its cost to shareholders using the share count, buybacks, and free cash flow

Why this matters

Why Earnings and Cash Differ listed pay in shares as one of the reasons profit and cash come apart. At many companies, especially in technology, it's among the largest costs there are. It's also the cost most often removed from the profit figures companies prefer to talk about. An investor has to decide how to treat it, and "ignore it because it isn't cash" is the one answer that's clearly wrong.

How it's measured

usually takes one of two forms:

  • Restricted stock units. A promise of shares that the employee receives after staying for a set time.
  • Stock options. The right to buy shares later at a price fixed today. They pay off only if the share price rises above that price.

Under US rules, the cost of an award is its fair value on the day it's granted, and that cost is recorded as an expense over the period the employee must work to earn it, which is usually the vesting period.1 Two things follow.

First, the expense is set at the grant date. If the share price doubles or halves afterward, the expense for that award doesn't change. Second, the value of a share unit is easy to measure, because it's the share price on the grant date. An option has to be valued with a pricing model, and the model needs assumptions about how much the share price will move and how long employees will hold the option. Those assumptions are disclosed in the notes, and they're estimates.

Worked example: one grant (hypothetical)
STU Corp grants an engineer share unitsAmount
Share units granted3,000
Share price on the grant date$40
Fair value of the grant$120,000
Vesting period4 years
Expense recorded each year$30,000

STU Corp records $30,000 a year for four years as part of its research and development expense, because that's where the engineer works. No cash is paid. As the units vest, 3,000 new shares are issued.

Where it shows up

Stock-based compensation in STU Corp's statements this year
StatementWhat happensSTU Corp
Income statementIncluded in the expense lines where the employees work. It isn't shown as a line of its own.$5 million, inside research and selling costs
Cash flow statementAdded back to net income, because no cash was paid.+$5 million in operating activities
Balance sheetPaid-in capital rises as the awards are earned.Paid-in capital up $5 million, to $60 million
Share countRises as awards vest and options are exercised.Average shares up from 19.6 to 20.0 million

The total for the year is in the cash flow statement and in a note, which also shows how much expense for awards already granted is still to come.1
