Real-world use cases
The store scaling ads at a loss
Revenue is climbing but the bank balance is not.
The calculator shows contribution per order barely covers CAC, revealing paid growth is unprofitable at the current price. Result: raise price or cut CAC before scaling.
The tempting sitewide sale
An owner plans a 20% promo.
Modeling the discount shows it wipes out most of the contribution, prompting a smaller, targeted offer instead. Result: sales that still make money.
Why revenue is a vanity number
Every Shopify dashboard leads with revenue, and revenue is the easiest number to grow and the most misleading. A store can double its sales and make less money, because revenue says nothing about what it costs to earn each order. Contribution per order, the amount left after every variable cost, is the number that tells you whether growth is building a business or digging a hole. This calculator strips a single order down to that truth.
The seven things that eat an order
Between the price a customer pays and the money you keep sit seven deductions: the discount that reduced the price, the cost of the goods, the shipping you cover, the payment processor's fee, the cost of acquiring the customer, and a realistic allowance for returns. Each feels small on its own, and together they routinely consume most of the order. Seeing them stacked in one place is often the first time an owner understands where the money actually goes.
The two quiet killers: CAC and discounts
Two of those costs do the most damage because they are the least visible on a per-order basis. Customer acquisition cost, the ad spend divided by orders won, can quietly exceed the entire product margin, which means every new customer is sold at a loss. And discounts come straight off the top line, so a modest-looking percentage off can erase a large share of contribution. The calculator isolates both so you can see their real weight.
From per-order truth to decisions
Once you know your contribution per order, the big decisions get clearer. You can see how many orders it takes to cover fixed costs, whether a promo is affordable, and how much you can actually spend to acquire a customer. Pair this with our Discount Profitability Calculator to test promotions, and with the Revenue Leak Calculator to find where orders are lost before they are ever counted.
Thin margins usually mean a conversion problem, not a pricing problem
When this calculator shows a slim contribution per order, the instinct is to raise prices or cut product cost. But the most common real cause is upstream: too much money spent acquiring each customer because the store converts too few of the visitors it already pays for. If your acquisition cost is eating your margin, the fix is not always a higher price, it is a store that turns more of its existing traffic into orders, which lowers CAC and lifts contribution at the same time.
That is conversion work: faster pages, sharper product pages, a smoother checkout, and better-qualified traffic. Digital Success helps Shopify brands lift conversion and lower acquisition cost so more of every order reaches the bottom line. Let us find the margin hiding in your funnel.
