Start With the Margin You Need to Manage
Start with the margin that matches the decision. Gross margin shows what remains after the product cost: gross profit divided by revenue. It excludes advertising, payment fees, fulfilment, wages, rent and other operating costs. Use it to assess product pricing, supplier costs and the basic economics of each beverage.
Contribution margin goes further by subtracting the variable costs you assign to each order or sale. That may include product cost, payment fees, shipping subsidies and advertising. Because businesses define variable costs differently, document the formula and apply it consistently. Use contribution margin to decide whether a product, campaign or collection is worth selling at its current economics. Net margin subtracts all operating costs, not just costs traceable to a sale. Use it to judge whether the store is profitable overall. A profit margin calculator can help keep the measures separate.
| Measure | Includes | Excludes | Best decision |
|---|---|---|---|
| Gross margin | Revenue minus product cost | Operating and selling costs | Price and product-cost decisions |
| Contribution margin | Revenue minus defined variable costs | Fixed overheads | Product, campaign or collection decisions |
| Net margin | Revenue minus all recorded costs | Nothing material to the profit calculation | Store-level profitability decisions |
Which Costs Belong in a Craft Beverage Margin
A useful craft beverage margin starts with the costs attached to making and delivering each sale. Product cost includes the beverage, ingredients, production, excise where applicable, and the supplier or co-packer charge. Add packaging such as bottles, cans, labels, cartons and inserts. Fulfilment covers pick-and-pack labour, warehouse handling and storage; delivery covers carrier charges, rural surcharges and replacement shipments.
Payment processing and platform costs belong in contribution margin because they occur when an order is sold. Include transaction fees, Shopify or marketplace charges and apps charged per order. Returns require the refund, return freight and unrecoverable packaging or delivery costs. Operating overheads, wages, rent, insurance, accounting, software and utilities, belong in operating or net profit, usually allocated across orders or revenue rather than assigned arbitrarily to one product.
- Use gross margin to judge product and production economics; use contribution margin after fulfilment, delivery, payment and platform costs to decide whether an order, product or campaign is worth scaling; use net margin after overheads to assess the whole store.
| Cost | Examples | Margin use |
|---|---|---|
| Product | Beverage, ingredients, production, excise, co-packer | Gross |
| Packaging | Bottle or can, label, carton, insert | Gross or contribution |
| Fulfilment | Pick-and-pack, handling, storage | Contribution |
| Delivery | Carrier, surcharge, replacement shipment | Contribution |
| Payment and platform | Processing, Shopify, marketplace, order apps | Contribution |
| Returns | Refund, return freight, unrecovered costs | Contribution or realised profit |
| Operating overhead | Wages, rent, insurance, software, accounting | Net profit |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a craft beverages store selling in Australia. 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 | A$89.99 |
| Price without tax | A$81.81 |
| Cost of goods | A$33.48 |
| Delivery and packing | A$11.82 |
| Payment fee | A$3.23 |
| Returns allowance | A$0.75 |
| Left over | A$32.53 |
| Margin on net price | 39.8% |

Read One Order From Checkout to Retained Profit
Read the worked order as a ledger, from left to right. Begin with the customer payment, then separate the amount retained as revenue from any GST treatment shown in the example. Remove refunds or other deductions next; a cancelled or returned order should not be treated as realized revenue. Then follow the order-specific product cost, packaging, payment and fulfilment costs, and any advertising allocation. The final amount is what remains as retained profit for that order, not the cash collected at checkout.
Each checkpoint answers a different question. Gross profit shows what the order retained after product cost, while contribution after advertising shows whether acquiring that order left an economically useful amount. Net profit goes further by including the other costs assigned in the example. Use the measure that matches the decision: product economics, acquisition efficiency, or the full order result. Do not treat this one order as the store’s margin. Returns, repeat purchases, fixed costs, channel mix and order volume can change the store-wide result. ORVX can calculate realized revenue from delivered orders, report return value against revenue, and show profitability by product, collection and customer.
Why Tax Changes the Margin in Australia
GST collected is not revenue. If a customer pays A$110 for a taxable order, the GST portion is A$10, one-eleventh of the sale price, leaving A$100 as revenue before product and operating costs. The Australian Government’s GST guidance says GST is 10% on most goods and services, and registration is required once GST turnover reaches A$75,000 or more. Use GST-exclusive revenue when measuring gross margin and operating margin; use the GST-inclusive cash amount when reconciling checkout receipts and the amount collected for the activity statement (Source: business.gov.au (Australian Government)).
Tax paid from profit is a separate question. Income tax is calculated on taxable business income after allowable deductions and is not the same as GST remitted, so it should not be deducted from revenue as though it were product cost. For a final retained-profit view, model the relevant tax expense separately from operating profit, based on your structure and accountant’s treatment. Verify current rules with the Australian Taxation Office and business.gov.au. If you import low-value physical goods, also check the official international tax guidance: GST can apply to goods valued at A$1,000 or less, based on customs value excluding transport and insurance.
Where Craft Beverage Margins Leak
An A$100 sale with A$35 product cost appears to produce A$65 gross profit, but a A$10 discount, A$8 unrecovered delivery, A$4 breakage and A$12 refund leave A$66 before labour, advertising or overhead; A$10 packing and service labour plus A$3 stock loss leave A$53. Failed payments produce no collected revenue; cancelled or returned orders should be excluded. Read refunds by value and units, high-value damaged cases can distort averages, and include spills, expiry and theft in product economics. Use gross margin for pricing, but retained or contribution profit for acquisition. ORVX calculates delivered-order revenue, applies its product cost model, reports refund value, return rate and profitability by product and collection. Reconcile unallocated labour and stock loss separately; use the profit margin calculator.
What to Check Each Month
Each month, review delivered orders at order level: realised revenue, product cost, packaging, freight, payment fees, discounts, refunds and advertising allocation. Keep GST collected separate from revenue, and confirm taxable treatment for domestic and imported sales with your records or adviser. Compare products, collections, customer types and acquisition channels. Review gross profit, contribution after advertising, MER (total store revenue against total advertising) and attributed ROAS (selected campaign credit), plus returns by units and refund value against revenue. Act on material changes or specific leaks: reduce falling-contribution channel spend, fix weak product pricing or fulfilment economics, investigate unusual refunds, or test a price where justified. ORVX can surface a prioritised action with its reason and confidence; profit margin calculator helps check a scenario.
- Record revenue, GST treatment, costs, returns and advertising inputs consistently for like-for-like comparisons.
- Monitor stable results; investigate changed margin, return rate or contribution.
A useful craft beverage margin is not one headline percentage. It is a consistent view of what each order contributes, what tax and operating costs remove, and which cost movement deserves attention next month.
