Pricing decisions often look simple until the terms start to blur. A business owner may know the cost of a product or service and have a desired profit in mind, but using markup when they mean margin can produce a selling price that falls short of expectations.

Understanding the difference matters because pricing affects cash flow, competitiveness and the ability to cover wages, rent, software, marketing and other operating costs. For Australian businesses, it also helps create cleaner reporting, more consistent quoting and better conversations with bookkeepers, accountants and staff.

Margin and markup measure different things

Margin and markup both compare profit with cost and selling price. However, they use different starting points, which is why the percentages are not interchangeable.

Markup measures gross profit as a percentage of cost.

Markup = Gross profit ÷ Cost

Margin, usually called gross profit margin in this context, measures gross profit as a percentage of sales revenue.

Margin = Gross profit ÷ Sales revenue

Gross profit is the amount left after subtracting the direct cost of providing a product or service from the sale price. It is not the same as net profit, which also takes account of overheads and other business expenses.

For example, if an item costs a business $80 and sells for $100:

  • Gross profit is $20.

  • The markup is 25 per cent, because $20 is one-quarter of the $80 cost.

  • The margin is 20 per cent, because $20 is one-fifth of the $100 selling price.

The same sale has both a 25 per cent markup and a 20 per cent margin. Neither figure is wrong, but they answer different questions.

A markup answers: “How much have we added to our cost?”

A margin answers: “How much of each sales dollar remains after direct costs?”

Why confusing the two can lead to underpricing

The most common mistake is treating a target margin as though it were a markup.

Suppose a business wants to achieve a 25 per cent gross margin on an item that costs $80. If it adds a 25 per cent markup, the selling price becomes $100. As shown above, that produces a 20 per cent margin, not a 25 per cent margin.

To achieve a 25 per cent margin, the business needs to calculate the selling price differently:

Selling price = Cost ÷ (1 − Target margin)

Using the example:

$80 ÷ 0.75 = $106.67

At a selling price of $106.67:

  • Gross profit is $26.67.

  • Gross margin is 25 per cent.

  • Markup is approximately 33.33 per cent.

This difference becomes more significant where a business has tight margins, changing supplier costs or substantial overheads. A small pricing error repeated across many sales can materially reduce profitability.

The reverse is also true. If a business decides on a markup percentage but later reviews performance using gross margin, the result may look lower than expected. That does not necessarily mean the business has made an error. It may simply be comparing two different measures.

The formulas worth keeping on hand

A few simple formulas can make pricing decisions more consistent.

To calculate gross profit

Gross profit = Selling price − Direct cost

To calculate markup

Markup percentage = Gross profit ÷ Direct cost

To calculate margin

Margin percentage = Gross profit ÷ Selling price

To calculate a selling price from a desired markup

Selling price = Direct cost × (1 + Markup)

To calculate a selling price from a desired margin

Selling price = Direct cost ÷ (1 − Margin)

When using these formulas, convert the percentage to a decimal. For example, a 30 per cent margin is entered as 0.30.

It can also be helpful to convert between the two measures:

Margin = Markup ÷ (1 + Markup)

Markup = Margin ÷ (1 − Margin)

These formulas are particularly useful for businesses using spreadsheets, point-of-sale systems, inventory software or quoting tools. They allow the business to work backwards from the profitability target rather than relying on a rough estimate.

Start with the right cost base

The formulas are only as useful as the cost figure used in them. Before applying a margin or markup, a business needs to decide what “cost” means for that product, service or project.

For a retailer, direct cost may include the purchase price from the supplier, freight, customs charges, packaging and product-specific handling costs. For a trades business, it may include materials, subcontractor charges, equipment hire and direct labour associated with the job.

For a professional service business, the direct cost may be less obvious. It could include the time of employees delivering the work, specialist software used for a client engagement, contractor fees or other costs that arise specifically because the work is performed.

A practical approach is to separate costs into two broad groups:

  • Direct costs, which can be linked to a particular product, service, job or customer.

  • Overheads, which support the business more broadly, such as rent, administration wages, insurance, software subscriptions, marketing and general business costs.

Gross margin usually focuses on direct costs. However, a price that produces a healthy gross margin may still be inadequate if the remaining amount does not contribute enough towards overheads and a reasonable profit.

This is especially important for service businesses. Quoting only for materials and visible labour can overlook travel time, job preparation, client communication, rework, supervision, equipment maintenance, office support and periods when staff are not billable.

A business does not need an overly complicated costing system from the outset. It does need a method that is consistent, understood by the people preparing quotes and reviewed regularly.

Margin is not the same as net profit

A strong gross margin is encouraging, but it is not the final measure of business success.

Gross margin shows what remains after direct costs. Net profit looks further down the profit and loss statement after overheads, finance costs, depreciation, tax and other relevant expenses have been considered.

For example, a café may earn a good margin on individual menu items. Yet the business can still struggle if wages, occupancy costs, wastage, merchant fees and utilities absorb most of that gross profit.

Similarly, a consulting business may charge attractive hourly rates and report a high gross margin. If the business has low utilisation, significant non-billable work or large fixed costs, its net profit may remain modest.

For this reason, margin and markup should sit within a broader pricing and profitability review. Useful questions include:

  • Does the selling price recover the direct cost of the sale?

  • Is there enough gross profit to contribute to overheads?

  • Is the price aligned with the value provided to the customer?

  • Are supplier costs, wage costs or delivery costs changing?

  • Are discounts reducing the effective margin?

  • Does the business have enough cash flow to meet its commitments?

  • Is the product, service or customer segment genuinely profitable?

Reviewing these questions by product category, service line, project type or customer group can reveal where profits are being made and where they are quietly being lost.

A practical example for a small business

Consider a small business that sells a specialised product. The direct cost of obtaining, preparing and packaging the product is $120.

The owner wants to achieve a 40 per cent gross margin. If they mistakenly add a 40 per cent markup, the price becomes $168. The gross profit is $48, which represents a margin of only about 29 per cent.

To achieve a 40 per cent margin, the calculation is:

$120 ÷ 0.60 = $200

At a $200 selling price, the gross profit is $80, which is 40 per cent of the selling price.

That additional amount is not automatically net profit. It still needs to help fund the costs of operating the business. But it gives the business a clearer starting point for assessing whether the product is priced sustainably.

The same principle applies to service quotes. If a job has estimated direct costs, the business can work backwards from its required margin rather than simply adding a familiar percentage to materials or labour.

Pricing decisions need more than a formula

Margin and markup are valuable tools, but a formula alone should not determine the final price. Businesses also need to consider the market, customer expectations and the practical realities of delivering the product or service.

Factors that may affect the final price include:

  • competitor positioning and comparable alternatives;

  • the value and level of service offered;

  • lead times, availability and supply risk;

  • customer demand;

  • minimum order quantities;

  • volume discounts;

  • payment terms and merchant charges;

  • returns, warranties and potential rework;

  • delivery, installation or after-sales support; and

  • whether the work carries unusual complexity or commercial risk.

A lower-margin product may still have a place in a business if it attracts customers who then purchase other profitable products or services. Equally, a product with a high apparent margin may not be worthwhile if it requires disproportionate staff time, creates excessive customer service work or ties up cash in slow-moving stock.

The key is to make those decisions deliberately. A business should know when it is accepting a lower margin and why, rather than discovering the shortfall after the work has been completed.

GST, discounts and price presentation

Australian businesses should also take care to use a consistent basis when calculating margins and presenting prices.

For internal management purposes, businesses often assess sales and direct costs on a GST-exclusive basis where GST is not an income or expense of the business. However, the correct treatment can depend on the nature of the sale, the business’s GST position and whether input tax credits are available.

Discounts also need to be included in margin reporting. A product may have a strong standard margin, but the actual margin can reduce significantly after promotional discounts, loyalty offers, delivery incentives, refunds or negotiated price reductions.

When selling to consumers, price displays need to be clear and accurate. A business should ensure that customers can understand the total amount they will need to pay, including unavoidable charges. This is separate from the internal margin calculation, but both processes should be based on reliable pricing information.

It is also sensible to check that invoices, quotes, website prices, point-of-sale settings and accounting records all reflect the same intended pricing approach. Inconsistencies can create customer confusion and make it harder to analyse performance.

Building margin and markup into regular business reviews

Margin and markup work best when they are reviewed regularly rather than calculated only when prices are first set.

Supplier price rises, freight changes, wage increases, exchange rate movements, stock losses and altered customer behaviour can all affect profitability. A price that was appropriate several months ago may no longer deliver the required return.

A useful review process may include:

  1. Confirm the direct cost of each key product, service or job type.

  2. Identify the desired margin or markup, and be clear about which measure is being used.

  3. Check whether discounts, delivery costs and other charges affect the actual result.

  4. Compare expected gross profit with the overheads the business needs to fund.

  5. Review the results in the accounting records and adjust prices, processes or purchasing decisions where appropriate.

For many small businesses, the greatest value comes from focusing first on the products, services or jobs that generate the most sales or consume the most time. Even a modest improvement in pricing accuracy across these areas can improve decision-making and help protect profitability.

The key takeaway

Markup starts with cost, while margin starts with sales revenue. Because they use different denominators, the percentages are not the same, and using one in place of the other can lead to underpricing.

A sound pricing approach combines accurate direct costs, a clear gross margin target, regular review and an understanding of the overheads the business must recover.
