What Break-Even Return Actually Means
Break-even ROAS is the revenue required from advertising to cover the ad spend after the sale’s other variable costs are accounted for. For a Canadian drone order, start with realized sales revenue, then subtract product cost, shipping subsidies, fulfilment, payment fees, discounts, expected returns and refunds, warranty exposure, and any other cost that rises with each order. If a $1,000 sale leaves $250 after those costs, only $250 is available for advertising. A $250 ad cost therefore produces break-even ROAS of 4.0x ($1,000 ÷ $250). Use the break-even ROAS calculator to test your own order economics.
Sales tax needs consistent treatment. GST, HST, QST and similar tax collected for a government is generally not revenue available to pay for advertising, so exclude it from the revenue numerator. Non-recoverable taxes, import duties or other transaction costs may belong in variable costs. The Canada Revenue Agency lists GST/HST rates by province, including 5% GST in Alberta, British Columbia, Manitoba, Quebec, Saskatchewan and the territories; 13% HST in Ontario; 14% HST in Nova Scotia from April 1, 2025; and 15% HST in New Brunswick, Newfoundland and Labrador and Prince Edward Island (Source: Canada Revenue Agency).
Income tax should be handled consistently rather than casually added to revenue. The central comparison is contribution left after relevant variable costs versus the advertising spend needed to generate the order. A store can show positive ROAS and still lose money when contribution is thin. Conversely, a high break-even threshold can be appropriate for a high-ticket drone whose accessories, shipping and support leave little contribution.
What break-even return means
Break-even return is a cutoff, not a performance target. It answers: how much revenue must each advertising dollar generate before that order contributes neither profit nor loss? The calculation should use revenue you keep, then subtract product cost, payment fees, shipping subsidies and an allowance for refunds or returns. The remainder is the maximum ad spend the sale can support.
Tax treatment can change the threshold materially. The Canada Revenue Agency lists Ontario at 13% HST, Alberta at 5% GST, and Nova Scotia at 14% HST from April 1, 2025, among other provincial rates. If a drone sells for $1,130 including Ontario HST, the pre-tax revenue is $1,000. Subtract $600 product cost and $100 in other variable costs: $300 remains for advertising. Break-even ROAS is therefore $1,000 ÷ $300 = 3.33. Spending $300 at that return breaks even; spending more loses money before fixed overhead. Use the break-even ROAS calculator to test your own prices, costs and tax treatment (Source: Canada Revenue Agency).
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a drones store selling in Canada. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Break-even ad return = net price / margin before ads.
| Ad return (revenue / spend) | Ad cost per order | Left after ads |
|---|---|---|
| 2.50x | C$84.14 | -C$21.03 |
| 3.33x | C$63.10 | C$0.00 |
| 4.99x | C$42.07 | C$21.03 |
| 6.66x | C$31.55 | C$31.55 |

Reading platform numbers carefully
An ad platform’s ROAS is an attribution measure, not necessarily the return on every dollar your Canadian drone store spent. Check the platform’s attribution window, conversion definition and reporting currency before comparing it with Shopify revenue. A campaign can receive credit for an order that another channel also influenced, while delayed reporting can make recent performance appear incomplete.
Use attributed ROAS to decide whether a specific campaign, ad set or keyword is receiving enough credited revenue to investigate or adjust. Use MER, total store revenue divided by total advertising spend, to assess the blended efficiency of all channels. For illustration only, $12,000 in store revenue and $4,000 in advertising spend produces a 3.0 MER, regardless of which platform claims the orders. ORVX tracks MER and attributed ROAS separately and explains the difference.
Also check whether the revenue figure includes tax, cancelled orders or returns. GST/HST rates vary by province: the Canada Revenue Agency lists 5% GST in Alberta, British Columbia, Manitoba, Quebec, Saskatchewan and the territories; 13% HST in Ontario; 14% HST in Nova Scotia from April 1, 2025; and 15% HST in New Brunswick, Newfoundland and Labrador and Prince Edward Island. ORVX uses delivered orders only and keeps your trading currency consistent. Compare like-for-like figures with the break-even ROAS calculator (Source: Canada Revenue Agency).
New customers and repeat customers
New and repeat customers should not be judged by the same break-even ROAS. A first order often carries the cost of acquiring the customer, while a repeat order may arrive with little or no advertising cost. For illustration only, if a new customer buys a $1,000 drone and leaves $300 after product, fulfilment and other variable costs, $300 of acquisition spend consumes the order’s contribution. A repeat purchase with the same $300 contribution can remain profitable even when attributed ad revenue is zero.
Use first-order profitability to decide whether acquisition is economically viable now. Use customer-level profitability and repeat behaviour to assess whether the initial loss, if any, is being recovered over later orders. Blended MER is useful for the store-wide question, total revenue divided by total advertising spend, while attributed ROAS is useful for comparing campaign reporting. ORVX shows both separately, alongside customer-level profitability, so a drone store can see whether strong repeat economics are masking weak acquisition or whether new-customer spend is building profitable relationships. The right action depends on which group is driving the result: fix acquisition economics for new customers, or investigate retention and product-level contribution for repeat customers.
| Measure | Use it when |
|---|---|
| First-order profitability | Deciding whether acquiring a new customer works on the initial order |
| Customer-level profitability | Checking whether repeat purchases recover acquisition cost |
| MER | Evaluating total store advertising efficiency |
| Attributed ROAS | Comparing reported campaign performance within an attribution system |
Setting a target for drones campaigns
Set a campaign target above break-even when the goal is profitable growth, not merely avoiding a loss. Start with the contribution you want to retain after advertising, then solve for the maximum ad spend. For illustration only, a drone order with $300 in realized revenue and $210 in non-ad variable costs has $90 available before advertising. If you require $30 contribution after ads, allowable ad spend is $60, so the target ROAS is 300 ÷ 60 = 5.00. The break-even cutoff is 300 ÷ 90 = 3.33; performance between 3.33 and 5.00 is technically profitable but below your operating target.
Use the measure that matches the decision. Break-even ROAS tells you when a product or campaign stops covering its costs. Target ROAS tells you whether it is producing the contribution needed to fund overhead, risk and growth. MER is the store-level check on total advertising efficiency, including spend that platform attribution may not capture. Set targets by product or collection when margins differ: a high-margin accessory campaign can carry a lower target than a low-margin drone bundle only if its dollar contribution still meets your requirement. Test the arithmetic with ORVX’s break-even ROAS calculator, using realized revenue rather than unfulfilled sales.
