What this result does not account for
- Results are a model, not a quotation — an institution's own figures govern.
- Every input is an assumption; change one and the answer changes with it.
- Rounding is applied only at the display layer, so totals may differ by a cent from a statement that rounds each line.
In short: A 65% markup on a $42.50 cost gives a $70.13 price and a $27.63 profit — but that is a 39.39% margin, not 65%. Achieving a genuine 65% margin requires a 185.7% markup. Pricing at cost times 1.30 believing it yields a 30% margin delivers 23.08% and forfeits $5,464.29 per thousand units.
Formula
Two names for the same profit measured against two different denominators. Markup divides by cost; margin divides by price. Margin is always the smaller number.
Worked Example
- Apply the markup. $42.50 × 1.65 = $70.13.
- Find the profit. $70.13 − $42.50 = $27.63 per unit.
- Measure it against price. $27.63 ÷ $70.13 = 39.39% margin — not 65%.
- Invert for the target. A 40% margin needs 40 ÷ 60 = 66.67% markup, pricing at $70.83.
- Check the volume effect. The $0.70 gap per unit is $705.36 across a thousand units.
Analyst's note. This is the most consequential arithmetic error in small business, and it is systematically biased in one direction: it always overstates profitability. A retailer applying a 30% markup while believing they earn a 30% margin is actually earning 23.08%, and on a thousand units that is $5,464.29 of profit that was never there. The relationship is fixed — margin equals markup divided by one plus markup — so a 50% margin always requires a 100% markup, and the divergence grows as the numbers rise. Any business quoting percentages internally should state explicitly which of the two it means.

- A model output is not a substitute for a professional review of your position.
Practical Use Cases
Pricing a product to hit a required margin
Work backwards from the margin, never forwards from a markup that sounds right. Enter your target and the engine gives both the markup and the price. Check whether the resulting price survives contact with competitors using the Margin Calculator.
Auditing existing prices
Enter your actual cost and markup to see the margin you are genuinely earning. Businesses that have never done this frequently discover they are several points below where they assumed they were.
Setting a floor before discounting
Know the margin before you agree to a promotion. A 20% discount on a 39.39% margin leaves 24.24%; on a thinner margin it can go negative. Model the discount side with the Discount Calculator.
Methodology & Editorial Standards
Markup is expressed as a percentage of unit cost and margin as a percentage of selling price, which are the standard definitions in retail and wholesale. The engine converts between them using the exact identities rather than approximations. Unit cost should be the fully loaded landed cost — purchase price plus freight, duty and any per-unit handling — since omitting these is the second commonest source of margin error after the markup-margin confusion itself. Break-even divides fixed costs by unit contribution and assumes both cost and price hold constant across the volume, which ignores quantity discounts on inputs and any price elasticity in demand. Payment processing fees, returns and shrinkage are not modelled and all reduce realised margin. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Markup Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is the difference between markup and margin?
Both measure the same profit against different bases. Markup divides profit by cost; margin divides it by price. A 65% markup is a 39.39% margin — margin is always the smaller of the two.
How do I convert markup to margin?
Divide the markup by one plus the markup. A 65% markup gives 0.65 ÷ 1.65 = 39.39%. The reverse is margin divided by one minus margin, so a 40% margin needs a 66.67% markup.
Why does this distinction matter?
Because confusing them always overstates profit. Pricing at cost times 1.30 while believing you earn a 30% margin actually earns 23.08%, and across a thousand units that is $5,464.29 of profit that does not exist.
What markup do I need for a 50% margin?
One hundred per cent — you double the cost. The relationship is not intuitive, which is why so many businesses undershoot. A 60% margin needs 150% markup, and a 65% margin needs 185.7%.
Should I price on markup or margin?
Set targets in margin, because margin is what appears in your accounts and what determines whether fixed costs are covered. Use markup only as the mechanical step for converting cost into price.
What is a typical retail markup?
Keystone pricing — a 100% markup, doubling cost — is traditional in general retail and gives a 50% margin. Grocery runs far thinner, jewellery and fashion considerably higher. Industry norms vary too widely to generalise safely.
What should I include in unit cost?
Everything that scales with the unit: purchase price, freight, duty, packaging and per-unit handling. Omitting landed costs is the second commonest margin error after confusing markup with margin.
How do I calculate break-even?
Divide fixed costs by the contribution per unit. At $27.63 of contribution and $8,500 of fixed costs, you need 308 units before the business makes any profit at all.
What is contribution margin?
Price less variable cost — $27.63 here — the amount each sale contributes toward fixed costs and then profit. It is the single most useful number for deciding whether an additional sale is worth making.
Does a discount destroy my margin?
Disproportionately, yes. A 20% discount on a 39.39% margin cuts it to 24.24%, because the discount comes entirely out of profit while cost stays fixed. Always check the resulting margin before agreeing a promotion.
How do payment fees affect margin?
Card processing of 2-3% comes straight off margin, not off markup. On a 39.39% margin a 2.9% fee removes roughly two points, which matters greatly in low-margin categories.
Should margin be the same across all products?
Rarely. Fast-moving lines can carry lower margins because volume covers fixed costs, while slow-moving or specialised items need more. What matters is the blended margin across the mix.
What is gross margin versus net margin?
Gross margin is price less direct cost, which is what this engine computes. Net margin additionally deducts overheads, marketing and tax, and is invariably much lower — a healthy gross margin can still produce a loss.
How do I raise margin without raising prices?
Reduce landed cost through better sourcing or larger orders, cut shrinkage and returns, or shift the sales mix toward higher-margin lines. Each is usually more achievable than a price rise customers will notice.
Can markup exceed 100%?
Easily, and it must for any margin above 50%. A 185.7% markup is required for a 65% margin. There is no upper limit on markup, whereas margin can never reach 100% unless the product is free.
Is this markup calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
