Margin vs Markup — What's the Difference & Which to Use
The most commonly confused numbers in retail pricing — explained clearly for fashion buyers, brand founders, and merchandisers.
Margin vs markup is one of the most commonly confused distinctions in retail pricing — and getting it wrong can cost you thousands in lost profit without ever realising it. Both measure profitability on a product, but they use different bases: margin uses sell price, markup uses cost. The result is two very different numbers describing exactly the same transaction.
This guide explains the margin vs markup difference clearly, with the formulas, worked examples, and a live calculator. It also covers when to use each one — and why mixing them up in a wholesale negotiation is the most expensive pricing mistake in fashion retail.
For the full formula set, see the retail maths formula reference. To run your own numbers, use the gross margin calculator.
01 — Definitions
Margin vs Markup — Definitions
Both measure how much profit you make on a product. The difference is what you divide by — and that single change produces two very different percentages.
Gross Margin
Profit expressed as a % of sell price
Gross margin tells you what proportion of your revenue is profit after paying for the product. It's the standard measure used in retail P&Ls, buying negotiations, and merchandising reports.
Also called: gross profit margin, GM%, retail margin
Markup
Profit expressed as a % of cost
Markup tells you how much you've increased the cost price to arrive at the sell price. It's more common in wholesale, manufacturing, and cost-plus pricing contexts.
Also called: mark-up, cost markup, markup on cost
02 — Formulas
The Margin and Markup Formulas
The only difference between the two formulas is the denominator — sell price for margin, cost for markup.
Gross Margin % formula
GM% = (Retail − Cost) ÷ Retail × 100
Divide gross profit by the sell price. The result tells you how many cents of every dollar of revenue you keep after paying for the product.
$42 profit on $70 retail → $42 ÷ $70 × 100 = 60%
Markup % formula
Markup% = (Retail − Cost) ÷ Cost × 100
Divide gross profit by the cost price. The result tells you how many cents of profit you've added for every dollar of cost.
$42 profit on $28 cost → $42 ÷ $28 × 100 = 150%
Retail price from margin target
Retail = Cost ÷ (1 − GM%)
Work backwards from a gross margin target to find the retail price. The standard method in fashion buying and merchandising.
$28 cost, 60% target → $28 ÷ 0.40 = $70 retail
Retail price from markup target
Retail = Cost × (1 + Markup%)
Multiply cost by one plus the markup decimal. More common in wholesale and manufacturing pricing.
$28 cost, 150% markup → $28 × 2.50 = $70 retail
03 — The Difference
Why Margin and Markup Give Such Different Numbers
Same product, same profit — completely different percentages. Here's why, and what each number actually tells you.
| Cost (landed) | $28.00 |
| Retail price | $70.00 |
| Gross profit | $42.00 |
| Gross margin % ($42 ÷ $70 × 100) | 60.0% |
| Markup % ($42 ÷ $28 × 100) | 150.0% |
The gross profit is the same — $42. But expressed as a margin it's 60%, and as a markup it's 150%. The reason the numbers look so different is the base:
Margin divides by $70 (the larger number) — so the result is smaller.
Markup divides by $28 (the smaller number) — so the result is larger.
| Cost | Retail | Gross profit | Gross margin % | Markup % |
|---|---|---|---|---|
| $10 | $20 | $10 | 50% | 100% |
| $20 | $50 | $30 | 60% | 150% |
| $28 | $70 | $42 | 60% | 150% |
| $35 | $100 | $65 | 65% | 186% |
| $40 | $80 | $40 | 50% | 100% |
| $50 | $150 | $100 | 67% | 200% |

05 — Conversion
How to Convert Between Margin and Markup
You don't always need to go back to the original cost and retail figures — you can convert directly between margin and markup using these formulas.
Convert markup → margin
Margin% = Markup% ÷ (1 + Markup%)
Turn a markup percentage into the equivalent gross margin percentage.
150% markup → 1.50 ÷ 2.50 = 60% margin
Convert margin → markup
Markup% = Margin% ÷ (1 − Margin%)
Turn a gross margin percentage into the equivalent markup percentage.
60% margin → 0.60 ÷ 0.40 = 150% markup
| Gross margin % | Equivalent markup % | Retail multiplier on cost |
|---|---|---|
| 25% | 33% | × 1.33 |
| 33% | 50% | × 1.50 |
| 40% | 67% | × 1.67 |
| 50% | 100% | × 2.00 (keystone) |
| 55% | 122% | × 2.22 |
| 60% | 150% | × 2.50 |
| 65% | 186% | × 2.86 |
| 70% | 233% | × 3.33 |
| 75% | 300% | × 4.00 |
06 — When to Use Each
When to Use Margin and When to Use Markup
The right measure depends on context. Using the wrong one in a negotiation or P&L is where the confusion becomes a real cost.
Use gross margin for
Retail P&Ls, buying negotiations, merchandising KPIs
Gross margin is the standard in retail. Buyers, merchandisers, planners, and finance teams all work in margin — not markup. Use it when building a range plan, setting OTB, reporting to management, or negotiating with wholesale accounts.
Use markup for
Wholesale quoting, cost-plus pricing, manufacturing
Markup is more common when pricing from a cost base — particularly in wholesale, manufacturing, and foodservice. If a supplier quotes "keystone plus 10%", they mean a 110% markup on cost, not a 110% margin.
Always clarify which measure is being used before agreeing a price
07 — Common Mistakes
The Most Costly Margin vs Markup Mistakes
Most margin vs markup errors happen at the point where two parties use the same word to mean different things.
Mistake 01
Quoting markup when a buyer asks for margin
If a buyer asks for a 60% margin and you use the markup formula, you'll price 38% too low. At scale, this wipes out your profitability on the entire wholesale channel.
Mistake 02
Reporting margin % when you calculated markup %
A 150% markup reported as "150% margin" on a P&L is a serious error. Finance teams and investors will question numbers that look implausibly high — and they should.
Mistake 03
Setting retail price from markup instead of margin
Using a 60% markup to set retail price gives a 37.5% gross margin — well below the 55–65% target for fashion. Every downstream metric (GMROI, maintained margin, OTB) will be off as a result.
Mistake 04
Not specifying which measure in a price sheet
Price sheets and product costings should always state whether a percentage is margin or markup. Leaving it ambiguous — especially across borders — causes consistent misalignment in wholesale partnerships.
FAQ
Frequently Asked Questions — Margin vs Markup
What is the difference between margin and markup?
Margin (gross margin %) is profit expressed as a percentage of the sell price. Markup is profit expressed as a percentage of the cost price. They describe the same dollar profit but produce different percentages. For a $28 cost and $70 retail: gross margin = 60%, markup = 150%.
Is margin or markup higher?
Markup is always higher than gross margin for the same product. Because markup divides by the smaller number (cost), it always produces a larger percentage than margin, which divides by the larger number (sell price).
Which should I use — margin or markup?
In retail, always use gross margin. It's the standard used by buyers, merchandisers, planners, and finance teams. Markup is more common in manufacturing and wholesale quoting contexts. When in doubt, use margin — and always specify which measure you're using in any negotiation or price sheet.
What is a good gross margin for fashion retail in Australia?
A gross margin of 55–65% is the typical target for fashion apparel in Australia. Luxury and premium segments can sit higher; value and off-price formats lower. Your initial markup should be set slightly above your target margin to allow for seasonal markdowns.
How do I convert markup to margin?
Use the formula: Margin% = Markup% ÷ (1 + Markup%). For example, a 150% markup → 1.50 ÷ 2.50 = 60% gross margin.
How do I convert margin to markup?
