What is the difference between gross margin and markup?

Gross margin is calculated as a percentage of the selling price (revenue-based): if something costs $10 to make and sells for $15, gross margin = ($15-$10)/$15 = 33%. Markup is calculated as a percentage of the cost: $5 profit on $10 cost = 50% markup. For investor and benchmarking purposes, always use gross margin (revenue-based). The confusion between the two is one of the most common errors in small business financial analysis.

What is a good net profit margin for a small business?

It depends heavily on the industry. In food retail or fuel distribution, 2-5% net margin is typical and viable at volume. In professional services, 20-35% is common. In software, 15-30%+ is standard. The ATO publishes small business benchmark data by industry code (ANZSIC) showing the typical profit margin range for businesses in each sector -- compare your margin to the ATO benchmark for your industry to assess whether you are performing in line with peers.

What does a high gross margin but low net margin mean?

A large gap between gross margin and net margin indicates high overhead costs (operating expenses). For example, gross margin of 50% but net margin of 5% means operating expenses consume 45% of revenue. This typically reflects high salaries, rent, marketing or administrative costs relative to the revenue generated. It often signals an opportunity to improve operating leverage -- growing revenue without proportionally growing overhead costs.

A small business owner is preparing a pitch to investors and needs to show their gross, operating and net margin clearly. They have revenue of $380,000, COGS of $190,000, operating expenses of $95,000 and tax of $22,000.

Gross margin = (Revenue − COGS) ÷ Revenue × 100 Operating margin = Operating income ÷ Revenue × 100 Net margin = Net income ÷ Revenue × 100 Healthy benchmarks: Gross >40% · Operating >15% · Net >10%
These vary significantly by industry — compare against your sector averages.

1 What this calculator does

Calculates gross profit margin, operating profit margin and net profit margin from revenue, cost of goods sold (COGS), operating expenses and tax. Shows absolute dollar profit at each level and the percentage margin for comparison to industry benchmarks.

2 Formula & professional reasoning

Gross profit = Revenue - COGS
Gross margin (%) = Gross profit / Revenue x 100
Operating income = Gross profit - Operating expenses
Operating margin (%) = Operating income / Revenue x 100
Net income = Operating income - Tax
Net margin (%) = Net income / Revenue x 100

The three margin levels tell a layered story. Gross margin shows how efficiently the core product or service is delivered (revenue minus direct production costs). Operating margin shows what is left after overhead and admin. Net margin shows the final bottom line after tax. Comparing all three identifies where profit is being lost -- a high gross margin with a low operating margin points to overhead problems; a high operating margin with a low net margin suggests high tax or interest costs.

3 Worked examples

⚠️ Illustrative example only — not clinical or professional instruction.

Basic

Small business income statement

Given: Revenue: $380,000 | COGS: $190,000 | Operating expenses: $95,000 | Tax: $22,000

Working:

Gross profit: $380K-$190K = $190,000 | Gross margin: $190K/$380K = 50% | Operating income: $190K-$95K = $95,000 | Op margin: $95K/$380K = 25% | Net income: $95K-$22K = $73,000 | Net margin: $73K/$380K = 19.2%

Answer: Gross margin: 50% | Operating margin: 25% | Net margin: 19.2%

💡 50% gross margin is strong for a product business (typical range 40-60% for manufactured goods). 25% operating margin is excellent. 19.2% net margin after tax is a very healthy small business result.

Standard

Tight net margin -- where is profit being lost?

Given: Revenue: $1,200,000 | COGS: $840,000 | Operating expenses: $280,000 | Tax: $18,000

Working: Gross: $360K (30% margin) | Operating: $80K (6.7% margin) | Net: $62K (5.2% margin)

Answer: Gross margin 30% | Operating margin 6.7% | Net margin 5.2%

💡 30% gross margin is typical for food retail. The gap between gross (30%) and operating (6.7%) is large -- $280,000 in operating overhead on $1.2M revenue is 23.3% of revenue. This is where to look for cost reduction.

Advanced

Benchmarking against industry

Given: Tech SaaS company: Revenue $500K | COGS $50K | Opex $300K | Tax $30K

Working: Gross: $450K (90% margin) | Operating: $150K (30% margin) | Net: $120K (24% margin)

Answer: Gross 90% | Operating 30% | Net 24%

💡 SaaS businesses typically have 70-90% gross margins because COGS is almost entirely infrastructure costs. The operating margin of 30% shows significant investment in sales and R&D. A 24% net margin is excellent for a growth-stage SaaS company.

4 Sanity check

Industry gross margin benchmarks

Software/SaaS: 70-90% | Retail: 30-50% | Food/Beverage: 20-40% | Manufacturing: 25-55% | Services: 40-70%

Industry net margin benchmarks

Strong: >20% | Good: 10-20% | Average: 5-10% | Thin: 2-5% | Concerning: <2%

Some high-volume low-margin industries (grocery retail, fuel) operate profitably below 2% net margin.

Gross margin vs operating margin gap

A large gap (>15%) between gross and operating margin suggests high overhead costs

This gap is where operating leverage improvements are found.

Revenue is not profit

A business turning $1M revenue with 2% net margin makes $20,000 profit

Revenue impresses; margin determines wealth.

5 Common errors

Error	Cause	Consequence	Fix
Including capital expenditure in COGS or operating expenses	Treating equipment purchases as a period expense	Profit understated in the purchase year; no recognition of the asset's ongoing value	Capital expenditure on equipment and assets is not expensed immediately -- it is depreciated over the useful life. Use the Depreciation Calculator to determine the annual depreciation expense, which is what belongs in operating expenses.
Confusing gross margin with markup	Using markup percentage (cost-based) when gross margin (revenue-based) is needed	Misunderstanding the actual profitability of the product line	Markup is calculated on cost: a 50% markup on $10 COGS = $15 selling price. Gross margin is calculated on revenue: ($15-$10)/$15 = 33% gross margin. For investor presentations and benchmarking, always use gross margin (revenue-based).
Not separating COGS from operating expenses	Grouping all costs together without the income statement structure	Gross margin cannot be calculated -- misleads on product profitability	COGS includes only the direct costs of producing goods or delivering services (materials, direct labour, delivery). Operating expenses are overhead: rent, admin salaries, marketing, insurance.
Using pre-tax profit as the final metric without calculating net margin	Reporting EBIT (earnings before interest and tax) as the profit figure	True after-tax profitability obscured -- especially for businesses with significant tax or interest obligations	Always calculate net margin on the after-tax profit for the true bottom line. Present all three margin levels (gross, operating, net) to give a complete picture.
