Revenue growth can coexist with declining profitability, slower collections and greater borrowing. Financial statement analysis connects those movements by establishing comparable data, selecting meaningful relationships and testing explanations against supporting records.
The analysis begins with its decision: explaining budget performance, evaluating near-term liquidity or assessing long-term solvency. That decision determines the required account detail, reporting periods, entity boundaries and supporting source systems.
Financial statements prepared under U.S. generally accepted accounting principles (GAAP) provide reported amounts, while the notes to the financial statements explain policies and relevant exposures. Reading the statements together distinguishes reported earnings from cash generation. Financial statement guide.
An attribute is a field describing a record, such as account, date, customer or currency. The attribute structures establish each field's meaning, type, permitted values and relationship to other records.
Data dictionary for an analysis extract.
Published reports support external comparisons, while internal ledgers, subledgers and budget files provide transaction detail and management expectations. Supporting notes identify matters such as restrictions, debt maturities, concentrations and accounting policies that a numerical extract alone may omit.
Common mistakes
- Current amount used as base. Dividing Lanton's $200,000 revenue increase by $1,200,000 produces 16.67%; the prior-period growth calculation uses $1,000,000 and produces 20%.
- Ending assets substituted silently. Lanton's $60,000 ÷ $900,000 produces 6.67%, while the stated average-asset ROA is $60,000 ÷ $800,000 = 7.50%.
- Sales used for inventory turnover. Using 1,200 ÷ 180 produces 6.67 times; the cost-based calculation is 780 ÷ 180 = 4.33 times.
Bottom line
- Comparable analysis requires consistent entity boundaries, periods, account mappings, units, currencies, field types and reconciled joins.
- Dollar changes, percentage changes, fixed-base trends and common-size shares answer different questions.
- Ratio interpretation depends on matched numerators, denominators, periods and average-versus-ending balance conventions.
- DuPont analysis separates profitability, asset utilization and leverage while reconciling their combined effect on equity returns.
Exam shortcut
Start with the requested comparison and underline its base: prior actual, budget, revenue, total assets or a contractual denominator. Mark each input as a period flow or a dated balance. Locate opening balances before calculating returns or turnover. When sales rise but earnings fall, bridge revenue, cost of sales, operating expenses, financing and taxes before proposing a cause. For a transaction question, rewrite both ratio components.
