Break Even ROAS for Dropshipping Gadgets in Singapore: The Number to Beat

What Break-Even Return Means

Break-even ROAS is the minimum revenue generated for each advertising dollar that covers the costs of the sale without creating a loss. It is not a target profit figure. For illustration only, if a gadget sells for $100 and $60 remains after product and other variable costs, the contribution margin is 40%. The sale contributes $40, so advertising $40 would break even: $100 ÷ $40 = 2.5 ROAS. A $100 ad budget would therefore need $250 in revenue at that margin.

The exact threshold changes when the costs included in contribution change, so use realized economics rather than a platform’s headline revenue. A break-even ROAS calculator can show the relationship between margin and the required ROAS.

Profit ROAS measures profit generated per advertising dollar, so it is useful when deciding whether paid acquisition created profit after advertising. At break-even, profit ROAS is zero; above it, the result is positive. Contribution margin measures the percentage of revenue left after variable costs, making it useful for setting or checking the break-even threshold. CAC measures advertising and acquisition spend per new customer, making it useful for comparing acquisition cost with customer value. CAC is not a substitute for ROAS: it ignores how much revenue each customer produces unless paired with order value and margin.

Build the Calculation From Sale to Contribution

Build the calculation from the amount collected to the contribution left for advertising. Start with realized revenue from a delivered gadget order, then remove refunds and every cost that rises with that order. If your selling price includes GST, separate the tax first: Singapore’s current GST rate is 9%, according to the Inland Revenue Authority of Singapore/basics-of-gst/current-gst-rates). Treat recoverable input GST according to your accounting treatment rather than counting it twice.

The supplied worked example should run through this chain. Contribution before advertising is the amount remaining after these deductions. Break-even ad spend equals that contribution; the corresponding break-even ROAS is realized revenue divided by allowable ad spend. Use the break-even ROAS calculator to check the arithmetic, then replace estimates with delivered-order and refund data.

Singapore Costs Need the Right Inputs

Singapore GST is the first local tax input to verify. The Inland Revenue Authority of Singapore (IRAS) states that the current GST rate is 9%. If your store collects GST, separate it from the amount treated as revenue in the break-even calculation; otherwise, you can overstate the money available to cover product, fulfilment and advertising costs. Use your actual GST treatment and records rather than assuming every order has the same tax status (Source: Inland Revenue Authority of Singapore).

Do not insert a blanket Singapore import-duty percentage for gadgets. Enter the duty actually applicable to each product, based on its classification and import documentation, and confirm the current treatment with Singapore Customs. If no duty is charged, record zero with supporting evidence. Keep import GST, duty, freight, insurance and brokerage as separate inputs where they appear on supplier or carrier documents; combining them hides which products have weak economics.

Compliance can also be product-specific. Record any required permit, inspection, certification, documentation or handling cost only when it applies to the gadget and is supported by the relevant Singapore authority or transaction record. Do not turn an unverified compliance assumption into a store-wide rate. These inputs belong in the product cost model before using the break-even ROAS calculator; Singapore sellers can also use the Singapore market guides for the surrounding local context.

Reading Platform Numbers Carefully

A platform’s reported ROAS answers a narrower question: how much revenue its attribution model assigns to ads. The answer depends on the attribution window, such as clicks or views recorded before a purchase. A seven-day click window can claim an order that would have arrived after an earlier visit, while a one-day window may miss a delayed gadget purchase. Different platforms can also claim the same conversion, so their totals should not be added together.

Store-level break-even ROAS answers a different question: whether the delivered orders and their contribution covered the advertising cost. For illustration only, if Singapore orders produce SGD 600 of contribution before ads and total advertising spend is SGD 500, the blended result is 1.2x, regardless of whether one platform reports 2.0x. Blended spend includes campaigns and channels that platform-level reporting may exclude. Store conversion reporting can also differ because of cancellations, returns, tracking loss, time-zone cut-offs and delayed order updates.

Use attributed ROAS to evaluate campaign delivery within a platform’s stated rules. Use blended store economics to decide whether the advertising programme is sustainable. ORVX tracks MER and attributed ROAS separately, using connected ad spend alongside Shopify revenue, and reports contribution after advertising by product and collection. That lets you compare the platform number with your break-even ROAS calculation instead of treating attribution as final profitability.

New Customers and Repeat Customers

Separate the first order from the customer relationship. First-purchase CAC is advertising spend divided by the number of new customers acquired. If a gadget order produces SGD 30 of contribution before advertising and the campaign pays SGD 25 to acquire that customer, the first order leaves SGD 5. Its first-order break-even ROAS is based on that order’s economics, not on a later purchase that may never happen.

Customer payback asks a different question: how many orders, and how much time, are needed for cumulative contribution to cover CAC? If the same customer generates another SGD 30 of contribution without a second acquisition cost, cumulative contribution becomes SGD 60 and payback is reached. This measure is useful for retention decisions, cash planning and comparing new-customer cohorts, while first-order ROAS is the right control for whether an acquisition campaign funds itself immediately.

Include repeat revenue in an acquisition model only when it is measured from your own cohorts, uses delivered orders and includes product, fulfilment, payment, refund and retention costs. Do not use an assumed lifetime value to call a loss-making campaign break-even. Report the first-order result separately, then show the observed payback period and customer profit. A customer-level view in ORVX can expose repeat behaviour alongside profitability; use the break-even ROAS calculator for the first-order threshold.
