Calculate →Markup vs. Profit Margin — The Difference That Costs Businesses Money
These two terms are frequently confused — and that confusion can silently destroy profitability. Here's the core distinction:
Markup: a percentage of cost
Markup % = (Selling Price − Cost) ÷ Cost × 100
A product that costs $50 and sells for $75 has a 50% markup. Markup is always calculated relative to your cost.
Gross Profit Margin: a percentage of revenue
Gross Margin % = (Selling Price − Cost) ÷ Selling Price × 100
That same $50-cost / $75-price product has a 33.3% gross margin — not 50%. If your business targets a 40% margin but you're quoting a 40% markup, you're leaving money on the table. Use the Markup Calculator to convert between the two instantly.
Why Freelancers Underprice Themselves
Most freelancers calculate their rate by dividing desired annual income by 2,080 working hours — and forget to account for self-employment tax (~15.3%), unpaid admin time, holidays, sick days, and business expenses. The result is an hourly rate that looks livable but leaves them below minimum wage after taxes. The Freelance Rate Calculator builds all of these factors in automatically.
Business Pricing Checklist
Before you set a price for any product or service, confirm all five of these:
- Know your true cost. Direct costs (materials, labor) are obvious. But don't forget overhead allocation — rent, software subscriptions, insurance, and your own time. Divide total monthly overhead by units produced and add it to each item's cost.
- Set a target gross margin, not a markup. Gross margin is what your P&L speaks in. If you need a 40% gross margin to cover operating expenses and profit, use the Markup Calculator to translate that into the correct selling price.
- Check competitor pricing. Your math might say $120 but the market expects $89. Price elasticity matters — sometimes a lower margin at higher volume is more profitable than a premium price that stalls sales.
- Account for payment terms and chargebacks. Net-30 clients cost you cash flow. Credit card processing fees (2%–3.5%) erode margin. Factor these into your effective cost before setting the final price.
- Stress-test against your loan obligations. If you're carrying business debt, your gross margin must cover debt service before you pay yourself. Use the SBA Loan Calculator or Business Loan Calculator to find your monthly debt service, then work backwards to the minimum revenue — and margin — you need.
