A company records $10 of stock-based compensation. Walk me through the three statements.
SBC is a $10 noncash expense. At 25% tax, net income falls $7.50. Cash flow adds back $10, so cash rises $2.50. On the balance sheet, paid in capital rises $10 and retained earnings fall $7.50. The real cost is dilution.

Example answer
50/100
Stock-based compensation is an operating expense, the same as cash wages. So pre-tax income drops by $10, and net income drops by somewhat less after tax.
On the cash flow statement, I open with the lower net income. The company paid its people in shares, not cash, so the $10 comes back in as a non-cash expense.
On the balance sheet, cash is up slightly. Equity changes too, so the two sides agree.
What holds it back
It knows the expense is non-cash, but there's no tax rate and the equity side is one vague phrase. Which equity accounts move, and by how much?
I'll assume a 25% tax rate and that the expense is deductible. Stock-based compensation is an operating expense, the same as cash wages. So pre-tax income drops by $10, tax drops by $2.50 and net income drops by $7.50. On the cash flow statement, I open with net income down $7.50. The company paid its people in shares, not cash, so the $10 comes back in as a non-cash expense. Cash flow from operations rises by $2.50, and that's the change in cash too. On the balance sheet, cash is up $2.50, so assets are up $2.50. Liabilities are unchanged. Inside equity there are two moves. Additional paid-in capital goes up by $10 for the shares granted, and retained earnings go down by $7.50. That nets to equity up $2.50, so the two sides agree.

Read literally, that says paying staff in stock leaves the company with $2.50 more cash, which is why I wouldn't stop there. The cost is real. It lands on shareholders through dilution, because the share count goes up and each existing share owns a smaller piece of the business. So I'd be careful with any cash flow or EBITDA figure that adds stock-based compensation back as if it were free. Either I treat it as an expense, or I put the new shares in the diluted share count. I shouldn't skip both. There's a caveat on tax. In practice the deduction comes when the award vests or is exercised, not when the expense is booked. Until then the $2.50 would be a deferred tax asset and cash would be flat.
The numbers, step by step
$10 of stock-based compensation at a 25% tax rate, assuming the expense is tax deductible in the period.
- Tax saved$10 × 25%
- $2.50
- Net income−$10 + $2.50
- -$7.50
- Cash flow from operations−$7.50 + $10 add-back
- $2.50
- Equity$10 paid-in capital − $7.50 retained earnings
- $2.50
What the interviewer listens for
- Do you treat it as an expense on the income statement?
- Do you add back the full $10 as non-cash?
- Do you know both equity accounts that move?
- Do you understand why it's still a cost to shareholders?
Common mistakes
- Saying only that equity goes down by $7.50.Additional paid-in capital also rises by $10, so equity is up $2.50 in total.
- Recording a liability for the $10.Stock awards settled in shares are equity, so the credit goes to additional paid-in capital.
- Concluding that stock-based compensation is free because cash goes up.The cost is paid by existing shareholders through dilution.
- Dropping the tax effect after assuming a tax rate, so the walk shows no change in cash when the deductible expense should save $2.50.
