Learn what return on average equity measures and why analysts use average equity instead of a single end-of-period balance.
The return on average equity (ROAE) measures profit relative to the average shareholder equity employed during the period. It is a refinement of return-on-equity analysis that reduces distortion from capital changes during the year.
Average equity is often more informative than ending equity when a company issues shares, repurchases stock, or experiences large retained-earnings changes during the reporting period. Banks and financial firms often use ROAE because equity balances can shift materially over time.
A common form is:
ROAE = net income / average shareholder equity
If a bank earns $40 million and its average equity over the year is $400 million, its ROAE is 10%.
A shareholder says, “ROAE and ROE always mean the same thing.”
Answer: Not always. They differ when average equity and ending equity are materially different.
