⚖️ Break-Even Calculator
Total monthly overheads — rent, salaries, software, utilities
Cost of goods + packaging + fulfilment per unit sold
Your price per unit — the higher above your variable cost, the fewer units you need to break even
Break-even units = Fixed Costs ÷ (Price − Variable Cost)
Every unit sold beyond break-even is pure contribution to profit.

About the Profit Margin & Markup Calculator

BizMargin helps retailers, wholesalers, and e-commerce sellers calculate gross margin, markup percentage, and break-even point instantly — no spreadsheet formulas to remember or get wrong.

Margin vs. Markup — Why It Trips People Up

These two numbers use the same inputs (cost and selling price) but divide differently, and mixing them up leads to real pricing errors. A 100% markup is only a 50% margin — the gap between the two widens the higher your percentage runs. This calculator computes both simultaneously so you're never guessing which one you're looking at.

Frequently Asked Questions

What's the difference between margin and markup? Margin is profit as a percentage of selling price; markup is profit as a percentage of cost. Same two numbers, different formula — see the calculator output for both side by side.

Does this work for service businesses, not just products? Yes — the same margin and break-even math applies whether you're pricing a product or a billable service; just use your cost-to-deliver instead of a product cost.

Is there a preset for Amazon FBA sellers? Yes, the FBA preset accounts for typical referral and fulfillment fees so you're calculating true margin, not just product-cost margin.

Do I need an account? No — every calculator on this site is free and requires no sign-up.
