Revenue growth shows whether a company is selling more; earnings growth shows what is left after costs and other income-statement items. Neither rate is automatically better. Compare them for matching periods, then look at margins, operating cash flow, share count, and how any adjusted earnings figure is calculated. The gap is a prompt to investigate—not a verdict on the company.
What revenue growth and earnings growth measure
Revenue is the top line: sales recognized during a reporting period. It is not necessarily cash collected during that period. Earnings usually means net income or net earnings—the amount remaining after costs and expenses, interest, and taxes are accounted for. The SEC’s beginner’s guide to financial statements explains how an income statement moves from sales through costs and expenses to net earnings.
Use comparable periods and the same accounting basis when calculating growth:
- Revenue growth = (current-period revenue − comparable prior-period revenue) ÷ comparable prior-period revenue.
- Earnings growth = (current-period earnings − comparable prior-period earnings) ÷ comparable prior-period earnings.
For example, compare a quarter with the same quarter a year earlier, or a full year with the prior full year. If prior-period earnings were zero or negative, a percentage-growth calculation may be undefined or misleading. Describe the direction and scale of the change instead of forcing a percentage.

Is earnings growth more important than revenue growth?
Not by itself. Revenue growth can indicate expanding sales, but it does not show whether those sales are profitable. Earnings growth reflects more of the costs and other items below revenue, but it can also be affected by taxes, interest, one-time gains or charges, and share-count changes. A company can grow sales while profit falls, or increase profit faster than sales; either pattern needs context.
There is no universal ideal gap between the two rates. Ratios and margins vary by industry, so compare a company with its own history and with similar businesses rather than applying one target to every company. In remarks dated May 31, 2001, then-SEC Chief Accountant Lynn E. Turner called top-line trends and growth “barometers investors use when assessing the company’s past performance and future prospects.” Turner noted that the views in the speech were his own, not necessarily those of the Commission or his colleagues (SEC speech).

How to diagnose the gap
Start with gross and operating margins
Margins help show whether profitability per sales dollar is changing. Compare gross margin and operating margin over time to locate where pressure or improvement appears. The SEC defines operating margin as income from operations divided by net revenues; it indicates the portion of each sales dollar that is profit at that stage (SEC guide).
- If earnings grow faster than revenue, possible explanations include improved margins, a shift toward higher-margin products or customers, lower costs, or changes in interest or tax expense.
- If revenue grows faster than earnings, possible explanations include margin compression, higher operating costs, spending tied to acquisitions or launches, interest, taxes, or one-off charges.
These are leads to investigate, not conclusions that growth rates establish on their own.
Check operating cash flow alongside net income
The cash flow statement reports cash inflows and outflows. For most companies, it reconciles net income to cash from operating activities by adjusting for noncash items and changes in operating assets and liabilities. Rising earnings with weak or declining operating cash flow merits a closer look at working capital, noncash gains, and collections; it is not automatic proof that earnings are poor quality (SEC guide).
Separate net income growth from EPS growth
Earnings per share (EPS) divides net income by outstanding shares. As a result, EPS growth can differ from net income growth when the share count changes. If you discuss per-share performance, compare diluted EPS and the diluted share count, not just net income.

Keep GAAP, adjusted earnings, and EPS distinct
Begin with reported net income and diluted EPS, clearly identified. If management also reports adjusted earnings or adjusted EPS, read the reconciliation: note which expenses, gains, taxes, and share counts were included or excluded, and why. Adjusted measures are not interchangeable with GAAP figures, and companies may calculate similarly titled measures differently. A recent SEC-filed issuer release warns that specified non-GAAP measures are not substitutes for GAAP measures and may not be comparable with measures carrying similar names at other companies (issuer release).
FactSet Research Systems Inc.’s fiscal 2026 fourth-quarter release illustrates how the measures can tell different stories. For that reported quarter, FactSet reported revenue growth of 6.3% year over year, net income down 21.1%, adjusted net income up 4.1%, diluted EPS down 15.4%, and adjusted diluted EPS up 11.6%. The company attributed the GAAP EPS decline mainly to higher operating expenses, including non-recurring items, and a prior-year divestiture gain; revenue growth and a lower share count partly offset those effects. FactSet cautioned that its non-GAAP information was not a substitute for GAAP financial information (FactSet fiscal 2026 fourth-quarter release). These are company- and quarter-specific figures, not a market benchmark.

A practical comparison checklist
- Match the reporting periods and accounting basis; use continuing operations when available and relevant.
- Compare revenue growth with net income growth, making clear what “earnings” means.
- Review gross and operating margin trends to see where profitability changed.
- Compare operating cash flow with net income for a separate view of cash generation.
- If considering per-share growth, check diluted EPS alongside diluted share count.
- For adjusted measures, inspect the company’s reconciliation and the rationale for each adjustment.
- Use organic, constant-currency, or acquisition-adjusted growth only when the company defines the measure and provides comparable reconciliations; definitions can differ.
