What is revenue growth (year-over-year)?

Revenue growth is the year-over-year percentage change in a company's total sales — a top-line measure of business expansion, independent of margins, taxes, or share count.

Why top-line growth without margin improvement is a warning sign

Strong revenue growth paired with flat or shrinking profit margins can mean a company is buying growth — discounting prices, spending heavily on customer acquisition, or expanding into lower-margin business lines — rather than growing profitably. The highest-quality growth shows revenue and margins improving together.

Live example: AAPL's latest year-over-year revenue growth is +6.0%, reflecting expanding its top line. See the full AAPL forecast for its Fundamentals card, including EPS growth alongside it.

What counts as strong revenue growth depends on the sector

A mature, capital-intensive business growing revenue in the low single digits can be entirely healthy for its category, while the same growth rate would be a red flag for an early-stage software company. Compare against sector peers and the company's own multi-year trend, not an arbitrary universal benchmark.

Frequently asked questions

Is revenue growth better than EPS growth?

Neither is 'better' on its own — revenue growth shows the business is selling more; EPS growth shows profit-per-share is rising. The healthiest combination is both improving together.

What does it mean if revenue grows but profit margins shrink?

It can mean the company is growing by discounting or spending heavily to acquire customers — worth investigating rather than treating the revenue growth alone as good news.

How much revenue growth is considered strong?

It's sector- and stage-dependent — double-digit growth is expected for an early-stage software company but exceptional for a mature utility.
