Why Revenue Rank Misleads
Revenue rank answers one narrow question: which product generated the most recorded sales value. It does not show which product leaves the most money after product cost, advertising, returns or other expenses. A helmet may have high sales value but expensive landed costs and frequent refunds. A jacket may sell less often while producing stronger gross profit. Gloves can generate steady order volume but require discounting, and small accessories may have modest sales value yet remain useful for increasing basket value.
The comparison also changes when you separate delivered revenue from cancelled or returned orders. A product’s sales figure can look healthy before refunds are deducted, particularly when sizing or fit drives returns. For a New Zealand store, compare figures in the store’s trading currency and account for GST treatment consistently; GST is charged at 15% in New Zealand (Inland Revenue (Te Tari Taake), GST) (Source: Inland Revenue (Te Tari Taake)).
Use revenue to understand demand and cash-generation scale, not to decide what to promote, retain or discontinue. ORVX shows product- and collection-level profitability alongside revenue, using delivered orders and a product cost model, then reports contribution after advertising. That makes the next comparison about economics rather than sales value alone.
Contribution per Product
Contribution is the money left after product cost and variable selling costs. The calculation is: realised revenue − product cost − variable selling costs = contribution. Variable costs can include payment fees, per-order fulfilment, shipping subsidies, marketplace fees and product-level advertising allocation. Keep every figure on the same GST basis; GST in New Zealand is charged at 15%, according to Inland Revenue (Te Tari Taake). A profit margin calculator can help check the arithmetic (Source: Inland Revenue (Te Tari Taake)).
Use contribution value when deciding which products materially support the store: a lower-margin jacket sold 100 times may produce more total contribution than a high-margin accessory sold 10 times. Use contribution per unit when comparing products, setting a minimum acceptable economics threshold or assessing whether another sale is worthwhile. ORVX reports contribution after advertising by product and collection, so both views can be checked against realised store performance.
| Measure | Calculation | What it tells you |
|---|---|---|
| Per-unit contribution | $180 − $90 − $12 = $78 | Money left from one sale |
| Total contribution | $78 × 40 units = $3,120 | Money left from the product's sales |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a motorcycle gear store selling in New Zealand. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Contribution = units x net price x margin.
| Product | Units | Revenue | Margin | Contribution |
|---|---|---|---|---|
| Product C | 192 | NZ$21756.88 | 34.6% | NZ$7518.87 |
| Product B | 182 | NZ$31487.30 | 21.7% | NZ$6826.98 |
| Product D | 140 | NZ$13100.79 | 28.5% | NZ$3738.51 |
| Product A | 30 | NZ$5165.54 | 15.3% | NZ$789.05 |

How to Read the Worked Example
Begin with units sold, the volume behind every figure. Read revenue as realised revenue for those units, excluding cancelled or returned orders, and check whether GST is inclusive or exclusive. GST in New Zealand is charged at a rate of 15% (Inland Revenue (Te Tari Taake), GST); apply the same treatment to every row (Source: Inland Revenue (Te Tari Taake)).
Check landed cost for each unit arrived ready for sale, multiplied by units sold, and its assumptions: purchase cost, inbound freight, duty and other included costs. Check selling costs, payment fees, marketplace charges, delivery subsidies or advertising, and compare rows only where treatment matches.
Trace revenue less landed and selling costs to contribution. Total contribution is the money left across the product’s units; use it for material store impact and per-unit contribution when comparing different volumes. The profit margin calculator checks inputs, not assumptions.
The Costs That Change the Comparison
The comparison changes when landed and selling costs are included. A $300 jacket with $150 product cost, $18 outbound freight, $9 payment fee and a $30 discount leaves $93 before returns or advertising, not $150. Include import or supplier freight where it belongs in product cost, and keep customer-paid shipping separate from delivery cost. For New Zealand stores, calculate GST consistently; Inland Revenue (Te Tari Taake) states that GST is charged at 15% (Source: Inland Revenue (Te Tari Taake)).
Returns require more than subtracting the refund: allow for return freight, inspection, repacking, damaged packaging and the risk that the item cannot be resold at full price. Warranty handling can include staff time, replacement freight and unrecovered supplier charges. ORVX reports return rate by units and refund value against revenue, while realised revenue excludes returned and cancelled orders. Per-unit storage, markdowns and stock-ageing write-downs can belong in product contribution when measurable. Warehouse rent, general salaries, software and other shared overhead should remain broader business costs unless allocated using a consistent method. Use contribution to compare products; use fully loaded profit to test whether the store’s total structure is sustainable. A profit margin calculator can check the arithmetic.
| Cost | Use in the comparison |
|---|---|
| Freight, payment fees, discounts | Product-level variable costs |
| Returns and warranty handling | Product-level expected cost where measurable |
| Storage and ageing | Product cost when tracked per unit; otherwise disclose separately |
| Rent, salaries, software | Broader overhead, not arbitrary product deductions |
Deciding What to Cut
Do not cut on contribution alone: check range role, repeat buyers and complementary sales. Use customer-level, product and collection profitability together.
- Keep or test: necessary category, repeat purchases or profitable complementary sales.
- Fix economics: avoidable discounts, freight, returns or service costs weaken contribution, but demand or range coverage justifies investigation.
- Reduce or clear: slow movement ties up remaining stock value without meaningful customer or collection benefits.
- Stop:
| Measure | Best used for |
|---|---|
| Contribution | Whether each sale earns enough after variable costs |
| Stock movement and remaining value | Whether inventory should be reduced or cleared |
| Service cost | Whether operational effort is eroding product economics |
| Repeat and complementary sales | Whether a weak direct result supports wider customer value |
A Quarterly Review Routine
At each quarter end, freeze the same date range and definitions: delivered units, realised revenue, product cost, variable selling costs, advertising, refunds, returns and inventory. Review products in the store’s trading currency, then compare with the previous quarter without changing the cost model halfway through. This keeps a motorcycle jacket, helmet or glove from appearing more profitable simply because the measurement changed.
Use two separate views. The contribution view shows whether each item earns money after product, selling and advertising costs; act on it when deciding product economics. The cash view shows refunds, stock value, remaining units and dead stock; act on it when deciding where working capital is tied up. A product can have positive contribution but still deserve attention if cash is sitting in unsold inventory.
Record one action and reason for every item: keep when economics and stock position are sound; test when evidence is limited but the range role is useful; reprice when the current price or discount leaves inadequate contribution; remove when weak economics and inventory drag persist after checking returns, costs and range purpose. Recheck the same decisions next quarter using the same fields.
A useful motorcycle gear profitability review does not produce a permanent product league table. It gives each item a consistent contribution calculation, makes stock and service costs visible, and connects the result to a specific decision. Review the same measures each quarter in NZD, investigate changes in assumptions, and keep products whose commercial role is clear even when their revenue is not the highest.
