Harbor Coffee, our fictional coffee business, reports sales of $1,050 million in FY2 and $1,100 million in FY3. Someone credits higher coffee prices. Does the extra $50 million prove it?
Revenue, or sales, is what a business earns from selling goods and services before costs—the top line of the income statement. The sales breakdown tells you which business line grew. Explaining why takes different evidence.
Two quick checks before the story
Year-over-year growth (YoY) compares a period with the same period a year earlier. For Harbor's FY3 growth, divide by FY2 revenue:
- What is Harbor's FY2-to-FY3 revenue growth?
- With FY1 revenue of $1,000 million, how many yearly intervals go into its FY1-to-FY3 CAGR?
The answers are about 4.76%, and two intervals giving about 4.88% a year. Skip the arithmetic box if you got both.
Three annual figures contain two growth intervals. CAGR joins the endpoints; it hides the path between them.
Quarter-over-quarter growth (QoQ) compares a quarter with the immediately preceding quarter. For Q3, the YoY denominator is last year's Q3 revenue; the QoQ denominator is this year's Q2 revenue. The same sales figure can look stronger or weaker depending on which base you choose.
A tiny starting base can turn a few extra dollars into a huge growth rate. With a zero base, you cannot calculate percentage growth.
What counts as earned sales
Revenue recognition means deciding when a sale belongs in the accounts. The main US standard for customer contracts ties revenue to the transfer of control: the customer receives the promised good or service, either at one point or over time.
Say you pay $120 upfront for a standalone annual service delivered evenly over 12 months. The provider earns $120 ÷ 12 = $10 of revenue each month as it provides the service. Getting paid early does not make the work happen early.
Recurring revenue comes from ongoing contracts or repeat purchases; a one-off sale has no expected repeat. An annual subscription has a contract behind it. A weekly coffee habit relies on the customer choosing to return. Neither promises another renewal or visit.
Trace the increase to business lines
A revenue segment is a part of the business disclosed separately. Harbor's teaching accounts give us a business-line breakdown: packaged coffee and shops.
From FY2 to FY3, both revenue stacks get taller without changing their proportions:
Packaged coffee adds $35 million (770 − 735); shops add $15 million (330 − 315). Together they account for the full $50 million increase.
Packaged coffee contributes 35 ÷ 50 = 70% of the gain. Its own growth rate uses a different denominator: 35 ÷ 735 × 100 ≈ 4.76%. Supplying 70% of the gain does not mean growing 70%.
Sales mix is the blend of products or services sold. Packaged coffee remains 70% of total sales and shops 30%. That unchanged split still leaves room for customers to choose different products within each line.
Harbor's FY2-to-FY3 evidence has a clear boundary:
| Claim | Evidence | Limit |
|---|---|---|
| Sales rose | $1,050m → $1,100m | Cause unknown |
| Both lines added sales | Packaged +$35m; shops +$15m | No product detail |
| Prices caused the gain | No prices or units given | Unproved |
The breakdown locates the gain. To test the pricing claim, you need prices and quantities for comparable products, or a disclosed estimate of their effects.
What the revenue note can tell you
Price is what customers pay for comparable goods. Sales volume is the quantity sold. A mix change shifts sales toward different products. Selling more expensive products can lift revenue without raising a single price.
Say a seller offers one product at $10 and sells 100 identical units: $1,000 of revenue. Raise both price and units by 10%, and sales become $11 × 110 = $1,210, up 21%. The effects multiply: 1.10 × 1.10 = 1.21. A mixed business needs more detail than one average price.
Apple's FY2024 annual report offers a real example. Note 2, printed page 35, separates iPhone, Mac, iPad, Wearables/Home/Accessories and Services sales. It also explains timing: most product revenue is recognized at shipment; services revenue is recognized over time as services are delivered.
Those categories and policies do not separate price changes from unit volumes. Management's discussion and analysis, or MD&A, is another place to look for explanations; the filings lesson shows where it sits.
Acquisitions can add another company's sales to the total. Currency translation can change the reported value of overseas sales. Either can move revenue without an equal change in the existing business's activity. Use these explanations only when the company discloses them.
Put the rate in context
High or low needs a comparison: the company's own history and businesses that sell in similar ways. Keep dollar growth beside percentage growth.
Suppose one business doubles its $1 million in sales while another grows its $100 million by 5%. The first adds $1 million; the second adds $5 million. The slower rate produces five times the extra sales.
You can explain Harbor in three sentences:
Harbor's revenue rose $50 million, or about 4.76%, from FY2 to FY3. Packaged coffee added $35 million and shops $15 million. Those totals do not establish how much came from higher prices, more units or a different mix of products.
Next, profit margins show how much of those sales survives each layer of cost. The later growth-quality lesson asks whether the growth can last and pay for itself.
In short
- Match the periods before trusting the growth rate.
- CAGR connects two endpoints; it cannot tell you how smooth the journey was.
- A line can contribute most of the sales increase without having the fastest growth rate.
- Getting paid early does not mean earning revenue early.
- A revenue breakdown shows where sales grew; a pricing story needs separate evidence.
