Percentage added on top of cost price
Markup vs Margin — What's the Difference?
Markup and margin both measure profit, but they use different bases. Markup is based on cost price, while margin is based on selling price. For the same dollar profit, markup is always a larger number.
| Markup | Margin | |
|---|---|---|
| Based on | Cost price | Selling price |
| Formula | (Sell−Cost)÷Cost×100 | (Sell−Cost)÷Sell×100 |
| 50% means | Sell = 1.5× cost | Sell = 2× cost |
| Always | Can exceed 100% | Never exceeds 100% |

Pricing Best Practices
Know the Difference
Margin is always a smaller number than markup for the same dollar profit. Confusing them can mean underpricing by 10-20% or more. A 50% markup is only a 33.3% margin.
Factor in GST
Australian businesses registered for GST must charge 10% on most goods and services. Always quote inc GST to consumers — it is a legal requirement under Australian Consumer Law.
Check Your Industry
Common markups vary widely: trades 30–60%, retail 50–100%, food service 200–300%, professional services 100–200%. Research your industry and factor in all overheads.
Frequently Asked Questions
What is the difference between markup and margin?
Markup is the percentage added on top of your cost price. It is calculated as (Selling Price − Cost) ÷ Cost × 100. Margin is the percentage of your selling price that is profit, calculated as (Selling Price − Cost) ÷ Selling Price × 100. For the same dollar profit, markup is always a larger number than margin. For example, buying at $100 and selling at $150 gives a 50% markup but only a 33.3% margin.
What markup percentage should tradies use?
Markup percentages for tradies typically range from 30% to 60%, depending on the trade and project type. Plumbers and electricians often use 40–60%, builders 20–40% on materials plus separate labour rates, and landscapers 30–50%. Your markup should cover overheads (insurance, vehicle, tools, super, admin time), not just materials. Always calculate your break-even point first, then add your desired profit on top.
Does this calculator include GST?
Yes. The calculator automatically adds 10% GST to the ex-GST selling price and shows the GST amount, the price excluding GST, and the total price including GST. If your business is registered for GST (required once your annual turnover exceeds $75,000), you must charge 10% GST on most goods and services. The markup and margin percentages shown are calculated on the ex-GST price.
How do I calculate margin from selling price?
Use the formula: Margin % = (Selling Price − Cost) ÷ Selling Price × 100. For example, if you sell something for $200 that costs you $120, your margin is ($200 − $120) ÷ $200 × 100 = 40%. You can also use this calculator in "I know my margin %" mode — enter your cost and desired margin percentage, and the calculator will show you the required selling price.
What are common markup percentages by industry?
Markup percentages vary widely by industry. Trades and construction: 30–60%. Retail clothing: 50–100%. Food service and hospitality: 200–300% (e.g. coffee beans to a cup of coffee). Professional services: 100–200%. Wholesale distribution: 10–25%. These are starting guidelines — your actual markup should be based on your specific cost structure, overheads, competition, and desired profit.
