What's the difference between single-step and multi-step income statements, and which is better for analysis?

Understanding income statement formats is foundational for CFA Level I analysis. Here's a clear breakdown:

Single-Step Income Statement:

Groups all revenues together and all expenses together, then calculates net income in one step.

Total Revenues              $XXX
- Total Expenses            ($XXX)
= Net Income                 $XXX

Simple but provides minimal insight into the sources of profitability.

Multi-Step Income Statement:

Provides intermediate profit measures at several levels:

Example — Birchwood Consumer Products:

Why multi-step is preferred for analysis:

1. Gross margin reveals pricing power and cost structure
2. Operating margin shows core business performance excluding financing
3. Trend analysis is more meaningful — you can see if margin erosion comes from rising COGS or bloating SG&A
4. Peer comparison requires operating-level metrics to compare across different capital structures

Where non-recurring items appear:

• Discontinued operations: Below net income from continuing operations (both IFRS and GAAP), net of tax
• Unusual/infrequent items: Within operating or other income sections, with disclosure
• OCI items: In comprehensive income, below net income (unrealized gains, foreign currency translation, pension remeasurements)
