Gross profit is turnover or revenue less the costs classified as cost of sales. Gross margin expresses that result as a percentage of revenue. Together they can reveal pricing power, input-cost pressure, product mix and project performance—but only where the filed accounts include a profit and loss account and the figures are genuinely comparable.
Direct answer
Open the company’s latest full financial statements and locate turnover or revenue, cost of sales and gross profit. Calculate gross margin as gross profit divided by revenue, multiplied by 100. Compare at least two periods and read the accounting policies and notes. If abridged or micro accounts omit the profit and loss account, do not estimate gross margin from the balance sheet.
Confirm the legal company and reporting perimeter
A brand may trade through several Irish companies, while consolidated accounts can include subsidiaries that are not party to your contract. Match the CRO number first, then determine whether the figures relate to the individual company or a group. Record the financial year end, period length, approval date and filing date before making any comparison.
Use the filing timeline to find consecutive accounts. If a business was acquired, disposed of or reorganised, the reporting perimeter may have changed. Read how to check turnover, revenue and profit before relying on a margin trend.
Gross profit, operating profit and net profit compared
| Measure | Typical calculation | What it helps test |
|---|---|---|
| Gross profit | Revenue less cost of sales | Direct trading economics before overheads |
| Gross margin | Gross profit divided by revenue | Pricing, product mix and direct-cost control |
| Operating profit | Gross profit less operating expenses, subject to presentation | Performance after overheads and operating items |
| Profit before tax | Operating result adjusted for finance and other relevant items | Result before the tax charge |
| Profit after tax | Profit after the tax charge or credit | Accounting result attributable after tax |
Labels and subtotals vary. Read the actual statement and policies rather than assuming every “operating profit” or “cost of sales” includes identical items.
How to calculate gross margin correctly
If revenue is €5 million and gross profit is €1.25 million, gross margin is 25%. Compare percentages as well as euro amounts. A company can increase gross profit in cash terms while margin falls because revenue grew faster at weaker economics.
- Use revenue and gross profit from the same period and entity.
- Adjust your interpretation for periods longer or shorter than twelve months.
- Check whether discontinued activities or acquisitions affect comparability.
- Do not compare a manufacturer directly with a commission-based agent without understanding revenue presentation.
- Use several years where available; one period can be distorted by timing.
What belongs in cost of sales?
Cost of sales can include purchased goods, raw materials, production labour, subcontractors, freight, manufacturing overhead and inventory movements. A service company may classify direct staff or contractor costs there. Another company might present similar expenditure within administrative expenses. That classification choice changes gross margin without necessarily changing operating profit.
Read the accounting policy, cost notes and business model. A change in allocation between cost of sales and overheads can improve gross margin mechanically, even when total costs are unchanged. Ask for a consistent management bridge where the decision is material.
Reasons gross margin may fall
Margin can decline because supplier prices, wages or freight increased faster than selling prices. Discounting, customer concentration, a lower-margin product mix, project overruns, warranty costs and inventory write-downs can also contribute. New contracts may begin at a lower margin to gain scale, while old favourable contracts expire.
Separate temporary from structural explanations. A one-off stock provision differs from permanent price competition. Compare the result with inventory and stock movements, debtors, customer terms and later trading evidence.
Reasons gross margin may rise
A rising margin can reflect price increases, favourable purchasing, a stronger product mix, improved utilisation or successful delivery. It can also result from releasing an inventory provision, capitalising costs, changing classifications or recognising higher-margin revenue near year end.
Higher margin is more convincing when supported by cash conversion, stable debtor days, repeat customers and consistent policies. Read the cash flow statement to see whether reported performance became cash.
Why the public record may not show gross profit
Many Irish small or micro companies file reduced public financial statements. Their publicly available filing may contain a balance sheet and notes but omit the profit and loss account. That lawful filing choice means revenue, cost of sales and gross profit may not be available publicly.
Do not reverse-engineer gross profit from stock, VAT, debtors, corporation tax or cash. Those figures do not provide a dependable substitute. For significant credit or acquisition exposure, request full statutory accounts or current management accounts and reconcile them to filed balance sheets.
Worked interpretation example
Suppose revenue rises from €8 million to €10 million while gross profit stays at €2 million. Gross margin falls from 25% to 20%. Operating profit falls from €700,000 to €300,000 and debtors rise sharply. Growth is real, but the company is earning less direct profit per euro of sales and collecting more slowly.
Ask whether the change came from product mix, a major low-margin customer, input inflation or disputed work. Review post-year-end collections, supplier terms, current pricing and a margin bridge. The conclusion should not be “revenue grew, therefore risk fell”.
Questions to ask before a decision
- Are revenue and cost classifications consistent between periods?
- What products, services or customers drove the change?
- Were inventory write-downs, rebates or warranty costs included?
- Did acquisitions, disposals or currency movements affect the result?
- How much gross profit converted into operating cash?
- Are current contracts priced to recover new input costs?
- Does management reporting reconcile to the filed accounts?
- What happens to profit and liquidity if margin falls another two points?
