How to Add a Profit Margin to Materials Without Losing the Job
Most tradies know they should be marking up materials. But a surprising number either don't do it at all, or do it inconsistently — and quietly lose thousands of dollars in recoverable revenue every year as a result. This guide covers exactly how to mark up materials correctly, what margins are standard across the trades, and how to handle the client who Googles your materials and questions your price.
Why You Should Mark Up Materials
Let's start with the "why" — because some tradies feel uncomfortable charging more than cost for materials, as if it's somehow not legitimate. It absolutely is legitimate. Here's why:
A materials markup isn't padding — it's compensation for real cost and real risk.
What Is a Standard Materials Markup in the Trades?
Markup percentages vary by trade and by the type and cost of materials, but here's a general guide:
| Trade | Typical Materials Markup |
|---|---|
| Electrician | 15–30% |
| Plumber | 15–30% |
| Builder | 15–25% on materials, 10–15% on subcontractors |
| HVAC / Air conditioning | 20–35% |
| Tiler / Flooring | 15–25% |
| Painter | 15–20% |
The range within each trade reflects the variation in job type and material value. For high-cost items like hot water systems, HVAC units, or switchboards, some tradies apply a tiered markup — higher percentage on lower-cost items, lower percentage on high-cost items — to keep the dollar amount reasonable while still protecting their margin.
Markup vs. Margin: Know the Difference
These two terms are often confused — and using them interchangeably will mess up your pricing.
The percentage you add to your cost.
Cost $100 + 20% markup = Sell price $120
The profit as a percentage of the sell price.
$20 ÷ $120 = 16.7% margin
| Desired Margin | Required Markup |
|---|---|
| 10% | 11.1% |
| 15% | 17.6% |
| 20% | 25% |
| 25% | 33.3% |
| 30% | 42.9% |
How to Apply Your Markup in Practice
Always quote from current supplier pricing, not from memory. Prices change — sometimes significantly — and quoting from a job you did six months ago can leave you out of pocket.
Pick a markup percentage for your trade and apply it consistently. Some tradies use tiered rates: under $50 cost → 30–40% markup, $50–$500 cost → 20–30% markup, over $500 cost → 15–20% markup.
You don't need to show your cost price and markup separately on your quote. Present a single line item for materials at the marked-up price. Clients don't see what you pay for labour components either — materials are the same.
Instead of:
Hot water unit: $780 + 20% markup = $936
Just write:
Rheem 250L electric hot water unit, supplied and installed: $936
How to Handle the Client Who Questions Your Materials Price
The internet has made clients more informed — and more likely to Google your materials and notice that the price on your quote is higher than what they'd pay at Bunnings or Reece. Here's how to handle it confidently:
"You're right that the unit itself retails at around $X. My price includes sourcing it through my trade account, delivering it to site, warranty management if anything goes wrong, and the labour to install it correctly. It's a packaged price for the whole service."
"You're welcome to supply your own materials — that's absolutely fine. My labour charge for the installation would then be [higher rate], as I can't guarantee the product or warranty materials I haven't supplied."
Many tradies charge a higher labour rate when clients supply their own materials because they take on more risk and lose their materials margin. It usually makes the client reconsider.
What not to do: don't apologise, don't justify in excessive detail, and don't drop your price unless you genuinely want to. A confident, matter-of-fact explanation works better than defensiveness.
Materials Management: Where Margin Leaks Happen
Even tradies who apply a markup consistently can lose materials margin in other ways. Common leaks:
- ✓Marking up materials is legitimate and necessary — your time, risk, and sourcing costs are real
- ✓Standard markups in Australian trades range from 15–35% depending on trade and material value
- ✓A 20% markup gives you a 16.7% margin — understand the difference
- ✓Present materials as a single line item in quotes, not as cost + markup
- ✓If a client questions your materials price, explain the value calmly and confidently
- ✓Watch for margin leaks: unused materials, missed items, and rush orders
Every dollar of materials margin you recover is profit you've already earned — you just need to make sure you're collecting it.
