Profit Margin & Markup — FAQ
25 questions answered about margin, markup, and pricing strategy.
What is profit margin?
Profit margin (gross margin) is the percentage of revenue that exceeds the cost of goods sold. It is calculated as (Revenue − COGS) ÷ Revenue × 100.
What is markup?
Markup is the percentage added to the cost of a product to arrive at its selling price. Formula: (Selling Price − Cost) ÷ Cost × 100.
What is the difference between margin and markup?
Margin is expressed as a percentage of the selling price; markup is a percentage of cost. A 50% markup results in a 33.3% margin. They are not interchangeable.
What is a good profit margin?
It depends on the industry. SaaS targets 60–80%, consulting 50–75%, retail 25–50%, restaurants 3–9%. Compare your margin to your specific industry benchmark.
How do I calculate profit margin from cost and price?
Margin = (Price − Cost) ÷ Price × 100. For example, if cost is $20 and price is $35: ($35 − $20) ÷ $35 × 100 = 42.9% margin.
How do I calculate selling price from target margin?
Price = Cost ÷ (1 − Target Margin%). If cost is $20 and you want a 40% margin: $20 ÷ 0.60 = $33.33.
How do I calculate selling price from markup percentage?
Price = Cost × (1 + Markup%). If cost is $20 and markup is 75%: $20 × 1.75 = $35.
What markup percentage gives me a 50% margin?
To achieve a 50% gross margin, you need a 100% markup. Use the formula: Markup% = Margin% ÷ (1 − Margin%) × 100.
What markup percentage gives me a 40% margin?
A 40% gross margin requires a 66.7% markup. Formula: 0.40 ÷ (1 − 0.40) × 100 = 66.7%.
What markup percentage gives me a 30% margin?
A 30% gross margin requires a 42.9% markup. Formula: 0.30 ÷ (1 − 0.30) × 100 = 42.9%.
Is margin or markup better to use for pricing?
Use margin when setting financial targets (e.g., we need a 40% gross margin). Use markup when buying from suppliers and adding a standard multiplier (e.g., we keystone everything at 2x cost).
What is a keystone markup?
Keystone markup is doubling the cost (100% markup), producing a 50% gross margin. It is a traditional retail pricing rule-of-thumb, especially in apparel.
What is gross profit vs. net profit?
Gross profit = Revenue − COGS. Net profit = Revenue − COGS − all other expenses (rent, wages, taxes). This calculator measures gross margin only.
Do I calculate margin before or after tax?
Gross margin is calculated before income tax. It measures your pricing efficiency, not your tax liability.
How does margin affect my break-even point?
A higher gross margin means you need less revenue to cover fixed costs and break even. Higher margin = faster break-even.
What industries have the highest profit margins?
Software/SaaS (60–80%), consulting (50–75%), pharmaceutical (40–60%), and financial services (30–50%) routinely post the highest gross margins.
What industries have the lowest profit margins?
Grocery retail (1–3%), gas stations (1–2%), restaurants (3–9%), and auto dealerships (2–5%) consistently operate on very thin margins.
How do I improve my profit margin?
Three levers: (1) raise prices, (2) reduce COGS through renegotiation or volume, (3) cut SKUs with below-average margins. Most businesses underutilize the price lever.
Should I use cost-plus or value-based pricing?
Cost-plus (markup from cost) is simple but leaves money on the table. Value-based pricing charges what the customer gains, which usually results in higher margins.
What is contribution margin?
Contribution margin = Revenue − Variable Costs. It measures how much each sale contributes toward covering fixed costs and generating profit.
How does shipping cost affect my margin for e-commerce?
If you offer free shipping, shipping cost is a COGS component. Include it in your unit cost when calculating margin. Free shipping on low-margin items often means losing money per order.
Can this calculator handle service businesses?
Yes. For service businesses, enter your labor + material cost as unit cost and your billing rate as price. This gives your gross margin on billable work.
What if my margin is negative?
A negative margin means you are selling below cost. This is unsustainable. Recalculate your true landed cost (including shipping, labor, overhead allocation) and adjust your price or reduce costs.
Is this calculator accurate?
