Free Shopify calculator

How much can you afford to spend acquiring an order?

Revenue and ROAS do not tell you how much money remains after product costs, fulfillment, shipping, fees, discounts, returns, rewards, and advertising.

Enter the economics of one typical order to estimate your break-even acquisition cost and a realistic marketing limit.

Understanding the results

Your affordable acquisition cost depends on volume, fixed costs, and the profit you want to retain

The highlighted result estimates how much you can spend acquiring each order after reserving enough contribution to cover the monthly fixed costs and profit target assigned to those orders.

Once total contribution after marketing covers fixed operating costs, each additional order with positive contribution adds to operating profit—until inventory, staffing, fulfillment capacity, or other costs increase.

Maximum acquisition cost at targetThe most you can spend per acquired order while covering the fixed costs and profit target entered

Absolute break-even acquisition costThe acquisition cost that consumes all contribution before fixed costs and profit

Fixed-cost requirement per orderThe fixed costs assigned to these orders divided by expected monthly order volume

ROAS required at your targetThe revenue return needed to preserve the fixed-cost and profit contribution entered
