How it is calculated

ROE = net income ÷ shareholders' equity × 100%. It doesn't answer "how much did the business earn" but "how efficiently did it earn on the owners' money specifically" — unlike ROA, it ignores borrowed funds entirely.

It's more accurate to use average equity for the period rather than the ending figure: if equity grew a lot during the year (say, from a capital injection), ROE on the ending figure understates how efficiently the money that was actually in play for most of the period was used.

There's no single "good" ROE — it varies heavily by industry and capital structure. A sensible benchmark is the return the owner could get investing the same money elsewhere (a deposit, another business, the stock market): a business with ROE below that alternative is using capital inefficiently, even if it's technically profitable.
