30% margin—how much can we discount in the tender?
At EUR 50 price, each 5% discount cuts roughly 1.5 margin points if cost is fixed—model EUR contribution, not gut feel.

Margin: plain-English definition, formula, worked example, how to interpret the result, peer-based benchmark guidance, common mistakes, and management actions in the ZBI Business Control Library.
What is Margin?
Margin percent is profit on the selling price—(price minus cost) divided by price. EUR 50 price and EUR 35 cost is 30% margin; the same numbers are 42.9% markup. Balkan Pack d.o.o. in Karlovac uses margin percent in pricing committees because it shows how much of each euro the customer pays remains after product cost.
Why Margin matters
Quoting 30% margin while landed cost moved to EUR 38 delivers 24% at unchanged price—you ship below the floor you thought you had. List price can hold while resin rises 8% and every deal still discounts from an outdated floor. Expedite and service policies get cut when contribution per unit shrinks—even though customers never saw a price list change. Stale standard cost makes margin percent decorative on the CRM while actual deals leak euros.
Formula and variables
Margin % = (Selling Price − Cost) ÷ Selling Price × 100
Selling price — net unit price before allocated overhead unless policy includes it in cost.
Cost — full product cost per policy (standard or actual).
Excel: =IFERROR((B2-B3)/B2*100,0)
Real business example
Balkan Pack d.o.o. in Karlovac prices a standard corrugated tray: selling price EUR 50; fully loaded product cost EUR 35 (material, labour, variable overhead). Margin % = (EUR 50 − EUR 35) ÷ EUR 50 × 100 = 30%. Procurement alerts that paperboard rose EUR 1.20 per unit effective June—cost becomes EUR 36.20 and margin at unchanged price falls to 27.6%. Sales needs EUR 51.40 to hold 30% margin; the pricing committee approves EUR 51 from July with a letter to top-20 accounts.
How to interpret the result
Margin percent is price-relative profitability—use it for price floors and deal comparison.
- 30% margin at EUR 50 leaves EUR 15 contribution before fixed overhead—not EUR 15 'profit' in the P&L sense.
- Compare margin to markup when sales and finance use different vocabulary—50/35 is 30% margin and 42.9% markup.
- Segment by SKU and channel; blended margin hides loss leaders.
- Update cost input when material or FX moves—stale cost makes margin percent decorative.
Benchmark context
Margin percent targets vary by channel: private-label packaging may run 22–28% at SKU level while spare-parts distribution runs 35–45%. Benchmark against your own price list from last price increase and against contribution hurdle after fixed allocation—not a single '40% or fail' rule. Peer trend: margin down 2 points year-on-year with stable list price almost always means cost or mix, not customer betrayal.
Red flags
- Blended margin down 3 points in one quarter with flat list prices—cost or mix shift eating contribution.
- Sales approving deals at 18% margin when policy floor is 25%—volume today, covenant stress tomorrow.
- Margin percent hero on new SKU using pilot-batch cost—scale cost not in the model yet.
- Export margin strong, domestic below floor—total margin OK until weak channel grows.
- Margin holds but ASP fell— you are discounting from a lower base; euros per unit still dropped.
Common mistakes
- Using purchase price instead of landed cost in the cost input.
- Comparing margin on ex-works price while competitors quote delivered duty-paid.
- Applying group-average margin to approve deals on high-service key accounts.
- Confusing margin with markup in the CRM—42.9% markup is not 'better' than 30% margin on the same SKU.
- Freezing standard cost for twelve months in an inflationary resin market.
What should management do next?
- Maintain SKU margin sheet with last cost update date visible to sales.
- Require finance sign-off on deals below floor margin with annual volume stated.
- Recalculate margin within five business days of any material surcharge from suppliers.
- Train commercial team on margin vs markup with the EUR 50 / EUR 35 worked example.
- Bridge monthly margin change: cost, price, mix, FX—in the pricing committee pack.

EUR 38 ÷ (1 − 0.30) ≈ EUR 54.29—round to commercial price band and check competitor ceiling.
Key account demands match competitor at 22% margin—walk away?
If contribution after service cost is negative, yes or rescope service. If positive but below hurdle, escalate with volume commitment.
Margin looks fine on standard cost but actual margin in P&L is lower—why?
Actual cost exceeded standard, or rebates sit below revenue line—reconcile margin report to P&L monthly.
Summary
Margin percent is (price − cost) ÷ price. Keep cost current, use it for price floors, and translate with markup vocabulary so sales and finance align.
