Many trade businesses work hard, stay busy, and still struggle to generate the profit they expected. One of the biggest reasons is a misunderstanding of the difference between margin and markup.

If you're setting job prices, quoting work, calculating charge-out rates, or planning to get off the tools and grow your business, understanding this difference is critical. Getting it wrong can mean thousands of dollars in lost profit every year.

What Is Markup?

Markup is the percentage added to your cost price to determine your selling price.

Formula:

What Is Margin?

Margin measures profit as a percentage of the selling price.

Formula:

Margin and Markup Are Not the Same Thing

This is where many trades businesses lose money.

Desired Margin	Required Markup
10%	11.1%
20%	25.0%
30%	42.9%
40%	66.7%
50%	100.0%

Many business owners say:

"I make 30% on every job."

When you dig deeper, they're often applying a 30% markup rather than achieving a 30% margin.

The result is significantly less profit than they expected.

Why This Matters When Setting Charge-Out Rates

Your charge-out rate must cover much more than wages.

A charge-out rate needs to recover:

Employee wages
Superannuation
Payroll tax (where applicable)
Workers compensation
Leave entitlements
Vehicle costs
Fuel
Tools and equipment
Insurances
Office and administration expenses
Marketing
Software subscriptions
Owner wages
Business profit

Many trade businesses calculate their hourly rate based on wages and then add a markup.

Unfortunately, if the target margin hasn't been considered correctly, the business may be working hard without generating enough profit to grow.

Want to Get Off the Tools?

This is where margins become even more important.

Many tradespeople dream of stepping back from the tools and focusing on:

Managing staff
Winning work
Growing the business
Spending more time with family

However, this only becomes possible when the business generates sufficient gross profit and net profit.

The business must earn enough to cover:

Business overheads.
Team wages.
The owner's replacement on the tools.
The owner's management wage.
A genuine business profit.

Without adequate margins, the owner simply creates another job for themselves rather than building a profitable business.

Key Takeaway

Many Australian trade businesses focus on markup when they should be focusing on margin.

Markup is what you add to costs.

Margin is what remains as profit.

Understanding the difference can significantly improve the profitability of your business and help you establish charge-out rates that support sustainable growth.

Before setting your next pricing structure or hourly rate, calculate the margin your business truly needs. The difference between markup and margin may be the difference between staying busy and building a profitable, scalable trade business.
