Margin vs Markup Calculator
Markup and margin measure the exact same profit dollars, but they're never the same percentage. I built this calculator so you don't have to keep second-guessing whether your selling price actually covers your costs.
How to Use This Calculator
-
1
Pick how you want to calculate
Switch to Markup → Price if you already know what percentage you add on top of wholesale. Use Margin → Price if you've got a strict target margin to protect.
-
2
Your unit cost
Type what you paid to produce, buy, or stock one item before factoring in any markup.
-
3
Plug in your target percentage
Put in the markup or margin percentage you want. If you're using margin mode, keep it under 100% since no physical item can hit pure 100% margin.

The Formula
People trip over this because markup and margin share the exact same numerator — your cash profit. The entire difference comes down to what you divide by. Here's how the math runs in both directions:
Selling Price = Cost × (1 + Markup ÷ 100)
Profit = Selling Price − Cost
Margin = (Profit ÷ Selling Price) × 100
Margin Mode:
Selling Price = Cost ÷ (1 − Margin ÷ 100)
Profit = Selling Price − Cost
Markup = (Profit ÷ Cost) × 100
Here is what each parameter means in practice:
- Cost What you actually spent to buy, build, or land one item on your shelf.
- Selling Price What your customer pays at checkout before local sales tax.
- Profit Clean cash in your pocket after subtracting your unit cost from the retail price.
- Markup Profit divided by your cost. It tells you what percentage you tacked onto your wholesale invoice.
- Margin Profit divided by retail price. It tells you how many cents of every revenue dollar you actually keep.
Why markup is always higher than margin: Both metrics use identical profit in dollars, but markup divides that profit by cost — which is smaller. Margin divides the same profit by retail price, which is larger. When you divide the same dollar bill by a smaller number, you get a bigger percentage every time. That's why a 25% markup only lands you a 20% margin.
Example
Most pricing mistakes happen when someone picks a number by gut instead of running the math. Honestly, I've never priced inventory — the closest I've come is selling an old phone second-hand and choosing a price mostly on feel, which is exactly what this page exists to fix. Say you buy a retail product wholesale for $80.00 and tell yourself you want a 25% profit margin. Here's how the actual numbers shake out:
Walking through the arithmetic step by step:
- Calculate divisor:
1 − (25 ÷ 100) = 0.75 - Calculate retail selling price:
$80.00 ÷ 0.75 = $106.67 - Calculate unit profit:
$106.67 − $80.00 = $26.67 - Calculate equivalent markup:
($26.67 ÷ $80.00) × 100 = 33.33%
Here's the trap that catches people. If you simply slapped a 25% markup onto that $80.00 cost, you'd sell at $80.00 × 1.25 = $100.00. That gives you $20.00 profit, which sounds fine until you realize that's only a 20% margin ($20 ÷ $100). That common slip costs you $6.67 in lost profit on every single unit you ship.
Frequently Asked Questions
What is the difference between margin and markup?
Markup looks backward at what you spent, while margin looks forward at what you collect. If you buy a product for $80 and sell it for $100, that $20 profit is a 25% markup on cost ($20 ÷ $80), but only a 20% margin on the sale price ($20 ÷ $100). Margin, I think. It answers the question I actually care about: how much of the final price is mine? But I get why shopkeepers quote markup — it's easier math off the cost. Mixing the two up is usually how people accidentally price their inventory too low.
Why is markup always higher than margin?
Both ratios put the exact same cash profit on top, but markup divides by cost while margin divides by retail price. Because your retail price is always higher than your cost on any profitable sale, dividing by that smaller cost number gives you a bigger percentage every time.
Can profit margin ever reach or exceed 100%?
No, margin tops out below 100% because you can't keep more than 100 cents of every dollar you bring in. Reaching a 100% margin means your item cost literally zero, and going past 100% is mathematically impossible. Markup, on the other hand, easily blows past 100%, 200%, or 500%.
What happens if I set markup or margin to 0%?
Your selling price equals your unit cost, leaving you with exactly $0.00 in gross profit. You're just swapping dollars with the customer. That might break even on the physical product, but your business takes a loss once rent, transaction fees, and shipping hit.
How do I turn a desired margin into a markup percentage?
Use the conversion formula: Markup = Margin ÷ (1 - Margin). To hit a 25% margin, you run 0.25 ÷ (1 - 0.25) = 0.25 ÷ 0.75 = 33.33% markup. Honestly, trying to divide decimals like 0.25 by 0.75 in your head during a supplier call is annoying, which is why running it through a calculator saves real money.
