How this break-even calculator works

This break-even calculator estimates how many orders you may need to cover your fixed monthly costs and variable selling costs.

Enter your fixed monthly costs, average selling price, product cost, shipping, packaging, marketplace fees, payment fees, ad cost per order and target monthly profit. The calculator then estimates your break-even orders, break-even revenue and orders needed to reach your target profit.

What it calculates

  • Break-even orders
  • Break-even revenue
  • Contribution per order
  • Variable cost per order
  • Profit after planned orders
  • Orders needed for target profit

Costs included

  • Fixed monthly costs
  • Product cost per order
  • Shipping cost per order
  • Packaging cost per order
  • Marketplace percentage fee
  • Fixed payment fee
  • Ad cost per order

Example break-even calculation

Suppose your fixed monthly costs are $300.00 and your average selling price is $35.00. If your variable cost per order is $21.27, your contribution per order is $13.73.

In that example, you would need about 22 orders to cover your fixed monthly costs. After that point, each additional order contributes toward monthly profit.

This can help you decide whether a product has enough margin before increasing ads, buying inventory or committing to a monthly tool or platform cost.

Break-even orders vs target profit orders

Break-even orders

Break-even orders estimate the number of orders needed to cover fixed monthly costs. At this point, estimated profit is close to zero.

Target profit orders

Target profit orders estimate how many orders may be needed to cover fixed costs and also reach your selected monthly profit goal.
