Markup Calculator converts product cost and a desired markup into a selling price. It also models discounts and sales tax, then shows realized markup, gross margin, unit profit, and total batch results—helping retailers, wholesalers, makers, and service businesses price consistently.

Markup and margin formulas
List Price = Cost × (1 + Markup %)
Discounted Price = List Price × (1 − Discount %)
Realized Markup % = (Discounted Price − Cost) ÷ Cost × 100%
Gross Margin % = (Discounted Price − Cost) ÷ Discounted Price × 100%
Tax-inclusive Price = Discounted Price × (1 + Tax Rate)
Symbols and pricing terms
| Symbol | Meaning | Denominator |
|---|---|---|
| C | Cost per unit | — |
| S | Selling price before tax | — |
| P | Gross profit per unit, S − C | — |
| Markup | Profit as a percentage of cost | Cost |
| Margin | Profit as a percentage of selling price | Selling price |
Worked example
An item costs $60 and receives a 50% markup, producing a $90 list price. A 10% discount lowers the selling price to $81. Profit is then $21 per unit, so realized markup is 35% and gross margin is 25.93%. With 8.25% tax, the customer pays $87.68, but the tax portion is not operating revenue. At 100 units, revenue before tax is $8,100 and gross profit is $2,100.
Markup versus margin
Markup and margin describe the same dollar profit from different denominators. Markup divides profit by cost; margin divides profit by selling price. Therefore, a 50% markup does not mean a 50% margin. A 50% markup produces a 33.33% margin before discounts.
| Markup on cost | Equivalent margin | Price on $100 cost |
|---|---|---|
| 25% | 20% | $125 |
| 50% | 33.33% | $150 |
| 100% | 50% | $200 |
| 200% | 66.67% | $300 |
Building a reliable product cost
Pricing quality depends on cost accuracy. Depending on the decision, unit cost may include purchase price, inbound freight, packaging, payment fees, direct labor, marketplace fees, waste, returns, and other costs tied to fulfilling one sale. Fixed overhead and target profit may require a higher markup than product cost alone suggests.
Discount planning
Discounts reduce both markup and margin. If promotions are common, set a list price that preserves acceptable unit economics after the expected discount. Also consider minimum advertised prices, channel commissions, coupon stacking, shipping subsidies, and tax treatment.
Common mistakes
- Confusing markup percentage with gross margin percentage.
- Applying markup only to supplier price while ignoring landed and fulfillment costs.
- Counting sales tax or VAT collected as profit.
- Forgetting that a discount is taken from selling price, not cost.
- Using the same markup for products with different risk, demand, or handling costs.
- Ignoring returns, spoilage, commissions, and payment-processing fees.
Frequently asked questions
How do I convert margin to markup?
Markup = Margin ÷ (1 − Margin), using decimal rates. For example, a 40% margin requires about a 66.67% markup.
How do I convert markup to margin?
Margin = Markup ÷ (1 + Markup). A 50% markup equals a 33.33% margin.
Can realized markup become negative?
Yes. A sufficiently large discount can push the selling price below cost, producing a loss.
Should tax be included in margin?
Normally no. Tax collected for a government is separated from revenue, though local rules and price-display requirements vary.
Is a high markup always better?
No. Higher prices may reduce sales volume or competitiveness. Evaluate contribution, demand, inventory turnover, and customer value together.

Markup Calculator pricing guide
The Markup Calculator converts cost-based markup into list price, discounted price, realized markup, gross margin, and unit profit. Use the Markup Calculator to test promotions before publishing a price, because even a modest discount can reduce realized markup and margin. The Markup Calculator also separates tax collected from operating revenue and profit.
Include landed, packaging, marketplace, payment, and fulfillment costs when they belong in the unit-cost decision. Run several Markup Calculator scenarios for different channels and order sizes, then verify tax treatment with current local rules. The U.S. Small Business Administration finance guide provides additional planning context. Revisit the Markup Calculator whenever cost, discount, or tax assumptions change.
