Price Calculator

A price calculator derives a selling price from a unit cost using one of three pricing methods, then cross-calculates the other two so all three profit metrics can be compared at once. Markup percentage adds a percentage of cost on top of cost. Profit margin percentage treats the margin as the percentage of the selling price that is profit. Fixed profit amount adds a flat dollar amount to cost.

Unit cost accepts decimals (10.50), fractions (21/2), mixed numbers (10 1/4), and values with currency symbols ($15.00) or commas (1,250). The value entered for the chosen method is the markup percentage (for example, 50 for a 50% markup), the target margin percentage (for example, 33.33 for a one-third margin), or the dollar amount of profit per unit.

A tax rate percentage adds tax to the selling price, and a discount percentage applies before tax. Quantity scales the per-unit result to total revenue and total profit for a batch of units. A step-by-step view displays the mathematical derivation of each result.

Selling Price (markup) = Cost x (1 + Markup% / 100). Selling Price (margin) = Cost / (1 - Margin% / 100). Markup percentage from a known selling price = (Selling Price - Cost) / Cost x 100. Margin percentage = (Selling Price - Cost) / Selling Price x 100. Discounted Price = Selling Price x (1 - Discount% / 100), applied before tax. Final Price = Discounted Price x (1 + Tax% / 100).

A $10 unit cost with a $5 fixed profit gives a $15.00 selling price, a 50% markup, and a 33.33% margin. At a quantity of 100, that is $1,500.00 in total revenue and $500.00 in total profit. Adding an 8% tax rate brings the price a customer pays to 15 x 1.08 = $16.20 per unit.

Pricing decisions affect profitability at every level of a business, from retail shelf tags to wholesale contracts. Cost, markup, and margin interact in the same way across each of the scenarios below.

• Retail Pricing: A store owner who buys inventory at $8.00 per unit and wants a 60% markup finds the $12.80 selling price; the cross-calculated margin of 37.5% is useful for comparing against industry benchmarks.
• Restaurant Menu Pricing: A chef targeting a 70% food cost margin on a dish that costs $4.20 in ingredients enters 30 as the margin percentage to find the $6.00 menu price needed to hit that target.
• Wholesale Negotiation: A distributor quotes $22.50 per case and the retailer needs at least $7.50 profit per case; entering $22.50 as cost and $7.50 as fixed profit confirms the $30.00 minimum selling price and shows the equivalent 33.33% markup and 25% margin.
• E-commerce with Tax: An online seller lists products at $49.99 with an 8.25% sales tax; the tax setting reveals the $54.12 total the customer pays, while the per-unit profit remains visible for margin tracking.
• Seasonal Promotions: A retailer running a 15% off sale on items normally marked up 80% sees the reduced selling price, the new effective margin, and whether the promotion still covers costs.
• Batch Ordering: A purchasing manager evaluating a 500-unit order at $3.40 per unit with a 45% markup sets quantity to 500 to see total revenue of $2,465.00 and total profit of $765.00 for the entire order.
• Freelance Project Quoting: A consultant with $120 in material costs per project and a target 40% margin finds the $200.00 quote price, confirming $80.00 profit per engagement.
• Comparison Shopping: Switching between markup and margin modes on the same cost reveals how the two metrics differ: a 100% markup yields a 50% margin, clarifying pricing conversations with partners who use different terminology.
