Start with the order-level profit question
Start with the order-level profit question: after a customer pays for one subscription box, how much of that sale is left after the costs required to deliver it, acquire the order and run the business? The answer depends on which profit measure you use. Revenue is the sales value of delivered orders. It tells you demand and cash collected, but not whether the box is economically viable.
Gross margin subtracts the direct product cost from revenue. For a box priced at $50 with $22 of products, gross profit is $28 and gross margin is 56%. Use it to assess pricing, sourcing and the underlying product economics before marketing and overhead.
Contribution margin goes further by subtracting costs that vary with each order, such as fulfilment, payment fees or advertising, according to your management definition. It is the right measure for deciding whether to scale acquisition or change the offer. Net profit subtracts the remaining business overheads as well. Use it to judge whether the whole store is profitable, not whether one campaign or box is attractive. For a reliable subscription boxes profit margin in Singapore, compare the same definitions across products, collections and periods.
| Measure | Subtracts | Best decision |
|---|---|---|
| Revenue | Nothing | Track sales volume and delivered-order value |
| Gross margin | Direct product cost | Review price, product mix and sourcing |
| Contribution margin | Variable order and acquisition costs | Decide whether to scale, reduce or fix an offer |
| Net profit | All recorded business costs and overhead | Assess the store's overall financial performance |
Build the margin bridge from price to cash left
Build the bridge in the same order the money leaves the sale. Start with the customer’s listed price, subtract discounts and refunds to get realized revenue, then deduct the costs required to make and deliver the box. Payment processing and platform charges belong after delivery costs. Finally, allocate recurring overhead such as software, salaries and storage using a consistent order basis.
The figures below are illustrative, not a Singapore benchmark. Contribution before overhead helps decide whether the box price, contents or delivery model works. Cash left after allocated overhead is the order’s net profit measure. Use the profit margin calculator to test your own values; ORVX calculates realized revenue from delivered orders only and does not count returned or cancelled orders as revenue.
| Bridge step | Calculation | Amount (S$) |
|---|---|---|
| Customer price | Listed selling price | 60.00 |
| Discounts | 60.00 − 5.00 | 55.00 |
| Refunds | 55.00 − 3.00 | 52.00 |
| Cost of goods | Product contents | −20.00 |
| Packaging | Box, inserts and tape | −3.00 |
| Delivery | Courier charge | −6.00 |
| Payment fees | Processing charge | −1.65 |
| Platform charges | Store and transaction charges | −1.00 |
| Returns | Return handling allowance | −2.00 |
| Overhead allocation | Software, labour and storage | −5.00 |
| Cash left | 52.00 − 20.00 − 3.00 − 6.00 − 1.65 − 1.00 − 2.00 − 5.00 | 13.35 |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a subscription boxes store selling in Singapore. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Margin = (net price - cost of goods - delivery - packing - fees - returns allowance) / net price.
| Line | Amount |
|---|---|
| Price the customer pays | S$54.99 |
| Price without tax | S$50.45 |
| Cost of goods | S$18.53 |
| Delivery and packing | S$9.38 |
| Payment fee | S$1.89 |
| Returns allowance | S$0.52 |
| Left over | S$20.12 |
| Margin on net price | 39.9% |

Which costs belong in a subscription box margin
Classify costs by whether they move with a delivered box. Direct per-order costs include the products, inserts, packaging, pick-and-pack labour, shipping, payment processing and any customer service effort tied to that order. A support team’s fixed salaries are recurring operating costs; a per-ticket support fee is direct. Keep the treatment consistent across every month.
Gross profit normally subtracts the cost of products and other costs required to make and deliver the box, such as inserts, packaging and fulfilment labour. Some businesses report shipping and payment fees below gross profit instead. Either convention can work, but label it clearly: gross margin is useful for checking sourcing and fulfilment economics, not for judging the whole acquisition model.
Contribution profit subtracts the remaining variable costs from gross profit, including shipping or transaction fees where they were excluded, order-level support, and advertising when measuring contribution after advertising. Use it to decide whether each subscription or collection adds cash before fixed overhead. Net profit then subtracts recurring costs such as warehouse or office rent, software, salaries, accounting, insurance and fixed customer service overhead. Use net margin to assess whether the business as a whole is profitable.
- Do not spread recurring overhead into each box and call that a direct product cost. Show the allocation separately so a change in order volume does not obscure the underlying unit economics.
- For a worked calculation, use the profit margin calculator and keep gross, contribution and net figures as separate lines.
| Measure | Costs included | Best decision use |
|---|---|---|
| Gross margin | Products, inserts, packaging and fulfilment costs | Check whether the box itself is economical |
| Contribution margin | Gross costs plus variable shipping, fees, support and advertising | Decide whether orders, products or collections add cash |
| Net margin | Contribution costs plus recurring operating costs | Judge the profitability of the complete business |
Why tax changes the margin in Singapore
GST can make the customer’s payment larger without increasing the amount your subscription box business retains. The current GST rate in Singapore is 9%, according to the Inland Revenue Authority of Singapore (IRAS). If a taxable box is advertised at S$100 inclusive of GST, the GST component is S$100 × 9/109 = S$8.26, leaving S$91.74 before fulfilment, product, shipping and other costs. If S$100 is quoted before GST instead, the customer pays S$109 and the S$9 GST is not operating revenue (Source: Inland Revenue Authority of Singapore).
Registration status matters. IRAS states that a Singapore business must register for GST when its taxable turnover for a calendar year exceeds $1 million, or when it expects taxable turnover of more than $1 million in the next 12 months. Do not apply the registered-business calculation without checking whether that rule applies to your business and sale (Source: Inland Revenue Authority of Singapore).
For imported low-value goods, IRAS defines the goods as having a sales value of S$400 or below when imported into Singapore by air or post. IRAS also states that a GST-registered overseas supplier charges GST at the point of purchase. That treatment can change the amount retained from an international subscription order, so record whether GST was collected at checkout or handled on import rather than treating the full customer payment as revenue.
Which costs belong in a subscription boxes margin
Not every cost should be forced into the same margin. Put product, packaging, fulfilment and delivery costs in the product-level calculation when they are required to deliver that box. Keep advertising separate: a box can have a healthy gross margin but lose money after acquisition spend. For illustration only, a S$60 realised sale less S$24 in box and delivery costs gives S$36 gross profit; less S$15 advertising leaves S$21 contribution after advertising.
Include customer support, software, storage, salaries, rent, accounting and other operating overhead when calculating net profit, but do not disguise them as product cost. If S$10,000 of monthly overhead supports 1,000 delivered boxes, an allocated S$10 per box is useful for planning, not for claiming that each shipment consumed S$10 of variable cost. Use gross margin to assess sourcing and box economics, contribution after advertising to assess acquisition, and net margin to decide whether the business is sustainably profitable. The profit margin calculator can model these layers; ORVX reports product, collection and overall profitability from your store’s own data.
