Markup and margin both describe the relationship between cost and price, but they divide by different numbers — markup divides the profit by cost, margin divides it by price. Because price is always larger than cost (assuming you're profitable), margin is always a smaller percentage than markup on the exact same dollar figures. Mixing the two up is the single most common pricing mistake retailers and freelancers make.
The Formulas
- Markup % = (Price − Cost) ÷ Cost × 100
- Margin % = (Price − Cost) ÷ Price × 100
- Price from target Margin % = Cost ÷ (1 − Margin% ÷ 100)
- Price from target Markup % = Cost × (1 + Markup% ÷ 100)
Worked Example: Same Numbers, Two Different Answers
Suppose a product costs you $50 and you sell it for $80. Your profit is $30 either way, but:
- Markup % = $30 ÷ $50 × 100 = 60%
- Margin % = $30 ÷ $80 × 100 = 37.5%
A 60% markup and a 37.5% margin describe the identical sale. If you tell a supplier "I need a 60% margin" when you actually mean a 60% markup, you'll under-price the item and quietly erode your profit — the gap between the two numbers grows as markup increases.
Why the Target-Margin and Target-Markup Prices Differ
If you want a 30% margin on that same $50 cost, the price is $50 ÷ (1 − 0.30) = $71.43 — not $65, which is what a naive "add 30% to cost" calculation (a 30% markup) would give you ($50 × 1.30 = $65). Solving for a target margin always requires dividing by (1 − margin), not multiplying by (1 + margin); that's the formula this calculator's second and third modes automate so you don't under-price by mistake.
FAQs
Q: Can margin ever equal markup?
A: Only at 0% (when price equals cost, both are 0%). At any positive profit, markup % is always higher than margin % on the same numbers.
Q: Can margin be 100% or more?
A: No — margin approaches but can never reach 100%, since that would require cost to be zero. Markup, by contrast, has no upper limit, which is why entering a target margin of 100% or higher in this calculator returns no result.
Q: I have several products with different costs — which metric should I standardize on?
A: Use margin % when comparing profitability against revenue (most income statements and investor reports are margin-based). Use markup % when setting prices from a known cost, since it's the more natural "add X% on top of cost" mental model for purchasing and retail pricing.
