Ecommerce Profit Margins: Singapore vs USA

Every example and amount on this page is illustrative. It shows the method and is not a benchmark, a quote or advice.

What the Singapore–USA Comparison Actually Measures

The Singapore–USA comparison is a comparison of profitability ratios, not market size or sales performance. A margin shows how much of recognised revenue remains after a defined set of costs. Singapore and USA figures are comparable only when they use the same revenue basis, cost definitions, reporting period and treatment of returns, discounts, taxes and currency.

Gross margin measures what remains after the cost of goods sold, so it evaluates product economics and pricing before operating overhead. Operating margin also deducts operating expenses such as marketing, payroll, software and fulfilment overhead, showing whether the trading operation works. Net margin goes further by including items such as interest and tax; it is the closest measure of what the business ultimately keeps. See Gross Margin vs Net Margin in Ecommerce for the distinction.

A cross-market margin can show that one business retains more or less from each dollar of comparable revenue. It cannot, by itself, show which market has higher demand, greater revenue, better cash flow or higher absolute profit, or identify why the gap exists. Those conclusions require the underlying costs and operating context.

• Revenue is the sales amount; margin is the retained share of revenue after specified costs.
• Markup is profit measured against cost, not revenue. A product bought for $40 and sold for $60 has a $20 markup on cost, while its gross margin is measured against the $60 sale.
• Contribution margin subtracts costs that vary with an order or sale, often including fulfilment, payment fees and advertising. It is useful for product, channel and campaign decisions, but it is not the same as operating or net margin. See Ecommerce Contribution Margin.

The Formula, Stated Plainly

Start with realised net revenue, not the gross value shown at checkout. For either Singapore or US sales: net revenue = delivered order value − discounts − refunds and returns. Exclude cancelled orders. Treat GST collected in Singapore and sales tax collected in the USA as amounts held for the tax authority rather than revenue, and apply the same rule to both markets. If shipping is charged to the customer, record it consistently as revenue and record the related shipping cost separately. Keep SGD and USD calculations separate; convert only for a comparison using one stated exchange-rate policy.

Gross margin isolates the economics of the product: [(net revenue − COGS) ÷ net revenue] × 100. COGS should cover the product cost and, under your chosen policy, directly attributable landed costs such as inbound freight and duties. This is the right measure for pricing, sourcing and product mix. Shopify’s published formula uses the same structure: [net sales − COGS] ÷ net sales × 100. See the distinction in gross margin vs net margin.

Contribution margin goes further: [(net revenue − COGS − payment fees − fulfilment and delivery costs − return costs − advertising) ÷ net revenue] × 100. Use it to judge an SKU, collection, channel or campaign after variable selling costs; contribution margin explains why it is useful. Net profit margin is [(net revenue − COGS − all operating expenses) ÷ net revenue] × 100, including overhead, payroll, software, rent, interest and tax according to your reporting policy. Use it to assess the whole business, not a single product.

A Worked Example in Singapore Dollars

Consider one delivered Singapore order with a checkout total of SGD109. Assume the order includes SGD9 of GST, so recognised net revenue is SGD100. The SGD9 is collected for tax rather than treated as sales revenue. Assume the product cost is SGD32, payment processing is SGD3.27 (3% of the SGD109 collected), and delivery costs SGD6. The order produces SGD68 gross profit, or a 68% gross margin. After payment and shipping, contribution before advertising is SGD58.73, or 58.73% of net revenue.

Now apply the same economics to 200 delivered orders in a month. The example assumes the brand is GST-registered and that figures exclude recoverable input GST. Advertising is SGD4,000 and fixed overhead—such as software, salaries and storage allocation—is SGD2,500. The monthly P&L is:

Which Costs Change Between Singapore and the USA

Tax changes the margin denominator before it changes profitability. For a Singapore order, GST collected from the customer is a tax liability, not sales revenue. A Singapore brand selling into the USA instead needs to assess the applicable state and local sales-tax obligations, which depend on the transaction and the seller’s tax position. Record tax separately from realised revenue in both cases; otherwise, a tax-inclusive Singapore order can look larger than a comparable US order.

Marketplace economics are not interchangeable across the two markets. A Singapore marketplace or a US marketplace may deduct referral, payment-processing, fulfilment, storage, advertising, or other seller charges under its own schedule. The relevant comparison is the fee actually incurred per delivered order and the currency in which it is billed—not a generic marketplace percentage. Reconcile marketplace payouts to order-level revenue, refunds, and fees before calculating contribution margin. Contribution margin is the measure to use when deciding whether a channel or product covers variable selling costs.

Fulfilment and shipping can also move in opposite directions. Shipping a US order from Singapore may add international freight, delivery surcharges, customs-related costs, longer return routes, and currency conversion. Holding inventory in the USA can reduce the distance to US customers, but introduces storage, inbound transfer, fulfilment, and returns costs. Neither setup is automatically more profitable: compare the complete delivered-order cost with the same product, destination, and service level.

For a Singapore-based brand, report Singapore and US sales in their trading currencies first, then show any consolidated view using an explicit conversion method. Separate exchange-rate movement and payment-provider conversion charges from product and fulfilment costs. ORVX keeps each merchant’s trading currency separate rather than mixing currencies in one figure, helping prevent a currency movement from being mistaken for a margin improvement.

The Mistakes That Make the Number Wrong

The first error is confusing markup with margin. If a product costs SGD40 and sells for SGD60, the markup is SGD20 ÷ SGD40 = 50%. The gross margin is SGD20 ÷ SGD60 = 33.3%. Markup describes the increase over cost; margin describes the share of recognised revenue retained after that cost. They cannot be compared as if they were the same measure.

The second is mixing levels of profitability. Gross margin subtracts product cost, while net margin also accounts for operating expenses. Advertising creates another important checkpoint: SGD100 of recognised revenue less SGD60 of product cost gives a 40% gross margin; less SGD20 of advertising leaves SGD20 of contribution after advertising, or 20% of revenue. That is not automatically net profit. Use gross margin and net margin for the correct scope, and contribution margin when deciding whether a product or channel is economically worth promoting.

Returns, refunds and cancellations can make the number look stronger if they remain in sales while their costs remain in expenses. GST creates a similar distortion: treating tax collected from customers as revenue inflates both sales and the denominator. Finally, do not compare a Singapore brand selling high-return fashion through paid social with a US brand selling repeat-purchase essentials through email, then attribute the difference to country. Product mix, channel mix, fulfilment, returns and advertising intensity may explain more than geography. Compare like-for-like products or report the mix separately, in each market’s own trading currency and for the same period.

What to Do With the Answer

Act on gross margin when the question is product economics before marketing and overhead. If an item sells for SGD100 and costs SGD40, its gross profit is SGD60 and its gross margin is 60%. Use that result to review supplier costs, bundles, minimum prices and product selection. A high gross margin does not prove the item is worth scaling: fulfilment, payment fees, returns and advertising may consume the remainder. See gross margin vs net margin in ecommerce for the distinction.

Act on contribution margin when deciding whether to advertise, increase spend or keep a product in the range. It should include costs that change with the order, including advertising. For illustration only, SGD60 of gross profit less SGD25 of variable fulfilment and SGD20 of advertising leaves SGD15 contribution, or 15% of SGD100 revenue. Compare this result by product, collection and customer type, not just across the whole store. Contribution margin is the more useful control for campaign and catalogue decisions.

Use operating margin for decisions about the business’s fixed-cost structure: salaries, software, rent and other overheads. Use net margin to judge the final result after financing, tax and other below-operating items, and to decide whether the business is financially sustainable. A Singapore–USA comparison should therefore support different decisions at different levels:

• Pricing: start with gross margin, then check contribution margin so discounts do not create unprofitable orders. ORVX can identify where a price experiment is worth running, but it cannot estimate price elasticity or predict demand response.
• Advertising: use contribution after advertising, alongside MER and attributed ROAS. ORVX reports those measures separately rather than treating attributed revenue as total business performance.
• Product selection: compare product- and collection-level contribution, returns and remaining stock value. A product with strong revenue but weak contribution or heavy dead stock may need an economics fix, test or stop decision.
• Market decisions: compare contribution, operating and net margins for Singapore and USA sales only after applying each market’s actual fulfilment, returns, fees, tax treatment and overhead allocation. Keep each market in its trading currency; do not combine SGD and USD into one margin.

A Practical Reporting Setup for Singapore Brands

Create one reporting schema and apply it to both markets. Every order should carry a market (Singapore or USA), trading currency (SGD or USD), sales channel, acquisition source, product or collection, and order cohort month. Keep SGD and USD figures separate in the operating ledger; if management needs a group view, document the conversion rate and date in a separate summary rather than mixing currencies in one margin figure.

Use delivered-order cohorts for profitability analysis, then reconcile them to the finance ledger by month. Map Shopify refunds, discounts, GST or sales tax, payment fees, fulfilment, landed product cost and advertising spend to consistent categories. Record whether ad spend is channel-reported or attributed, and preserve the same treatment for Singapore and USA orders. This makes a change in margin traceable to mix, returns, freight, pricing or acquisition rather than a reporting change. Shopify’s standard dashboard may not provide every required cut; see Shopify Dashboard Limitations.

• Review each month by market × currency × channel × cohort, then drill into product and collection profitability.
• Reconcile order counts, delivered revenue, refund value, COGS, ad spend and contribution profit to the finance system before comparing margins.
• Use the same cohort window for both countries—for example, delivered orders placed in a given calendar month—and label incomplete cohorts separately.
• ORVX connects to Shopify and advertising accounts, keeps each merchant’s trading currency separate, and reports product, collection and customer profitability for audit-ready review.

A Singapore–USA margin comparison is useful only when both markets use the same definitions, cost categories and time period. Calculate margin at the order and business levels, separate recoverable taxes from true costs, and use the measure that matches the decision you need to make.
