Margin and markup measure the same profit against a different base. Margin is gross profit divided by the selling price. Markup is gross profit divided by the cost. A bearing that costs $11.60 and sells for $16.90 makes $5.30 of profit: a 31.4% margin and a 45.7% markup. Same sale, two numbers.
The difference matters as soon as one person sets prices in markup and another reads results in margin. A rep told to "hold 40%" who adds 40% to cost sells at a 28.6% margin, and nobody notices until the month closes.
The margin formula
Margin answers the question: of every dollar the customer pays, how much do we keep after the cost of the product?
Margin can never reach 100%, because that would need a cost of zero. This is why margin is the number on the income statement and the number most ERPs use for margin floors and approval rules.
The markup formula
Markup answers a different question: how much do we add on top of what we paid?
Markup has no ceiling. A $2 fitting sold at $8 carries a 300% markup and a 75% margin. Because markup starts from the cost, it is the natural way to build a price: take the landed cost and multiply.
Margin vs markup conversion table
The two numbers are linked, so you can always turn one into the other. These are the pairs that come up most in distribution.
At low percentages the two are close. By 40% the markup is two thirds higher than the margin, which is where most pricing mistakes happen.
How to convert margin to markup
Divide the margin by one minus the margin. Going the other way, divide the markup by one plus the markup.
To set a price straight from a margin target, divide the cost by one minus the margin. A 30% margin on the $11.60 bearing is $11.60 ÷ 0.70 = $16.57. To set it from a markup, multiply the cost by one plus the markup: $11.60 × 1.457 = $16.90.
The mistake that costs distributors money
Here is how the confusion plays out on a real quote. The pricing manager wants a 40% margin on the 6205-2RS bearing. The rep reads "40%" and adds it to the cost.
On a 500 unit order the difference is $1,545, and the quote still looks like it hit target because both people said "40%". Spread that across a few hundred quotes a month and the gap shows up as a margin shortfall finance cannot explain.
Write the word next to the number. "40% margin" and "40% markup" are different prices.
Quick answers with real numbers
These are the conversions that come up on a pricing desk every week.
- An $80 cost with a 25% margin target sells at $80 ÷ 0.75 = $106.67.
- The same $80 cost with a 25% markup sells at $80 × 1.25 = $100.00, a 20% margin.
- $1,000 of sales at a 5% margin is $50 of gross profit.
- A $16.90 price at a 31.4% margin means the item cost $16.90 × 0.686 = $11.59.
- A 35% margin target needs a 53.8% markup on cost.
When a number looks wrong, recompute it in dollars. The dollar profit is the same whichever percentage you use, so it settles any argument about which one somebody meant.
Margin vs markup vs profit
Gross profit is the dollar amount: price minus cost, $5.30 on the bearing. Margin and markup are two ways to express that same $5.30 as a percentage. Net profit is a different number again, what is left after rent, wages and every other overhead, and it only exists for the business as a whole, never for a single line.
When someone says "the profit on this quote", they almost always mean gross profit in dollars. Ask for the dollars when the percentage is unclear.
Which one should a distributor use?
Most distributors end up using both, each for one job.
- Margin to measure
Reports, margin floors, approval rules and rep targets.
- Markup to build
Price lists built from cost, often as a multiplier.
A common setup is to agree the target in margin, then store it in the price list as a multiplier. A 30% margin target becomes "cost × 1.43", a 25% target becomes "cost × 1.33". Reps never have to convert anything, and finance still reads the result in margin.
Discounts are where margin thinking pays off. A 10% discount on the $16.90 bearing brings the price to $15.21. Margin falls from 31.4% to 23.7%, and gross profit falls by almost a third, from $5.30 to $3.61. A rep who thinks of it as "10% off" rarely sees that a third of the profit just went. Set discount limits in margin, and show the profit in dollars next to them.
Where both numbers mislead
Margin and markup are only as honest as the cost behind them. Three things change the real number on a distributor's quote line:
- Supplier price, landed cost and average cost give three different margins on the same sale. Use landed cost, which includes freight and duty.
- A 3% supplier rebate lowers your true cost and a 3% customer rebate lowers your true price. Neither shows on the invoice. See how rebates work.
- Outbound freight, card fees and commission sit below gross margin. Contribution margin catches them.
A quote that shows 31% gross margin can end up at 24% once these land. A pricing engine that works from landed cost and knows the rebates on each line shows the margin you will actually keep before the quote goes out.

Common questions
Yes. Both describe the same price. A part that costs $80 and sells for $100 makes $20 of gross profit. That $20 is 20% of the $100 price, which is the margin, and 25% of the $80 cost, which is the markup.
A 30% markup on a $10 cost gives a $13 price and a 23.1% margin. A 30% margin on the same cost needs a $14.29 price, which is a 42.9% markup. The margin target always needs the higher price, and the gap grows as the percentages rise.
Use margin to measure and report, because finance, your ERP and most margin floors work on the selling price. Use markup to build a price from a cost, because it is a simple multiplier. Agree on one word per job and write the percentage with it, so nobody reads one as the other.
