Find how many units you need to sell to cover fixed costs at a given price and variable cost.
Break-even units = Fixed costs ÷ (Price − Variable cost per unit).
Fixed costs 120,000. Price 2,000. Variable cost 1,100. Contribution = 900. Break-even = 134 units (rounded up).
It tells you the volume where contribution covers fixed costs. Below that volume you are funding the business. Above it, extra units contribute to profit — until you add more fixed cost.
Fixed: software, warehouse rent, salaried staff, photography retainers. Variable: product cost, pick-pack, payment fees, per-order ads if you truly spend per order. If ads are a monthly budget, treat them as fixed for the period you are modelling.
No. The calculation runs in your browser. Nothing is stored or transmitted.
Use any currency as long as every input uses the same one. The math does not depend on a currency code.
Units = Fixed costs ÷ (Price − Variable cost).
Calculate gross profit and profit margin from revenue and cost. Use it before you set a selling price or judge a channel.
Work backwards from cost and a target margin to the selling price you need.
Calculate return on investment from net profit and the amount invested.
Start an online store from offer and unit economics through platform, catalog, payments, shipping and a launch checklist — without treating legal registration as a how-to.
Define the store metrics that matter, run a simple reporting cadence, stay humble about attribution, and connect numbers to decisions — not to dashboards for their own sake.
Gross, contribution and net margin answer different questions. Channel fees, shipping and returns sit between list price and cash. Worked numbers included.
CAC is what you spend to win a customer. Blended and paid CAC answer different questions. This article lists what belongs in that spend—and what does not.
Markup is the add-on over cost. Margin is profit as a share of selling price. Mixing them up is a common pricing error. Formulas and a conversion table.
D2C, marketplaces, wholesale, subscriptions and dropshipping differ in margin, inventory risk and ops load. Compare the economics before you pick a model.
