Gourmet Food Customer Acquisition Cost in Australia: What You Can Afford

What the acquisition cost number is for

Customer acquisition cost (CAC) is the average amount spent to gain one new customer over a defined period: acquisition spend divided by first-time customers acquired. It is an observed efficiency measure, not a price you should automatically accept. Allowable CAC is the maximum you can spend per new customer while still meeting your profit target. Use it to set a bid, budget or campaign stop point; compare actual CAC with allowable CAC rather than with a market benchmark.

Keep the revenue basis consistent. For an Australian GST-registered store, business.gov.au states that GST is 10% and that registered businesses collect the GST portion as one-eleventh of the sale price. ORVX calculates realized revenue from delivered orders only, excluding returned and cancelled orders. Its CAC calculator helps structure the calculation, while MER, attributed ROAS and product or collection contribution answer different questions (Source: business.gov.au (Australian Government)).

• CPA: cost per conversion or order; useful when the conversion is not necessarily a new customer.
• CAC: cost per first-time customer; use it to assess customer acquisition efficiency.
• Allowable CAC: the economic ceiling per new customer; use it to decide whether to scale, reduce or stop spending.
• ROAS: attributed revenue divided by ad spend; use it to assess attributed ad efficiency, not profit.
• MER: total store revenue divided by total ad spend; use it as a broad store-level efficiency view.

What belongs in acquisition cost

Acquisition cost is the spend required to create and convert a first order. Include paid media, creative production, agency or contractor fees, advertising and attribution software, and promotions intended to win the customer, such as a first-order discount. Allocate recurring costs to the same period as the customers acquired. For illustration only, $4,000 in ads, $600 in creative and $400 in software gives $5,000 of acquisition spend before dividing by new customers. Use the CAC calculator to make the boundary explicit.

Keep product and order-delivery costs outside CAC. Cost of goods, packaging, pick-and-pack, shipping and other fulfilment costs belong in gross margin or contribution after acquisition; including them makes CAC look higher and mixes two decisions. Treat GST consistently as well. business.gov.au states that GST is 10% on most Australian goods and services, with the GST portion equal to one-eleventh of the sale price; registered businesses collect it. Compare spend and revenue on the same GST-inclusive or GST-exclusive basis, and label the choice. A promotion's discount belongs in acquisition cost only when it is deliberately used to obtain the first customer; the underlying product still belongs in product cost (Source: business.gov.au (Australian Government)).

First-order margin sets the ceiling

First-order contribution sets the maximum defensible CAC: the amount left from a delivered order after variable costs, before acquisition spend. Start with realised revenue, then subtract product cost, any shipping subsidy, payment fees, discounts and the expected cost of returns or refunds. If CAC exceeds this contribution, the first order loses money before fixed costs, wages and tax.

Use revenue excluding GST when assessing margin. business.gov.au states that GST is 10% on most Australian sales and that the GST portion is one-eleventh of the sale price. For illustration only, an $80 checkout total becomes $72.73 ex-GST. After the costs below, the ceiling is $25.33, not a target. A lower CAC leaves room for overhead and profit. Use the CAC calculator to test the arithmetic (Source: business.gov.au (Australian Government)).

How repeat orders change the limit

First-order CAC is the immediate cash-payback measure: compare acquisition cost with contribution from the first delivered order. A customer-level payback view includes contribution from expected repeat orders, but only when retention assumptions are based on your own cohorts. It is useful for deciding how much patience a profitable repeat-purchase model can justify.

For illustration only, assume A$30 contribution on order one, A$26 on each repeat, a 40% chance of one reorder and a 20% chance of a second. Expected customer contribution is A$30 + (0.40 × A$26) + (0.20 × A$26) = A$45.60. That does not make A$45.60 a safe CAC target: retention may weaken, delivery costs may rise or the customer may never reorder. Apply a deliberate 50% haircut, producing a A$22.80 planning limit. Use first-order CAC when cash payback and downside control matter; use customer-level payback when cohort evidence supports repeat demand. ORVX shows customer-level profitability and repeat behaviour, helping test whether the assumption matches delivered-order results. You can also model the starting guardrail with the CAC calculator.

Track CAC by channel, not only store-wide

Store-wide CAC can conceal uneconomic campaigns. Calculate new-customer CAC for each channel, campaign and first-order cohort using the same rule: allocated acquisition spend divided by first-time customers whose orders were delivered. For illustration only, A$4,800 spent on paid social producing 120 new customers gives A$40 CAC. Allocate shared agency or creative costs consistently, or comparisons will be distorted.

Use channel CAC to decide where the next dollar of budget deserves review; use campaign CAC to reduce, test or stop specific targeting and creative; use cohort payback to judge whether customers acquired in a given month recover CAC through later contribution. Payback should use contribution after variable costs, not revenue. The CAC calculator can check the arithmetic, while customer-level profitability helps validate repeat contribution.

How to read the worked example

Treat the worked example as a decision model, not an Australian benchmark. Read each input first: average first-order revenue, contribution margin, new-customer count, acquisition spend and the period measured. Recalculate it with delivered orders only, then check whether discounts, freight, payment fees, packaging, returns and agency costs were treated consistently. For Australian stores, also confirm whether figures are GST-inclusive. The Australian Government states that GST is 10% on most goods and services and that registered businesses collect the GST portion, one-eleventh of the sale price (Source: business.gov.au (Australian Government)).

Test the result against your own data by comparing the modelled CAC with actual new-customer CAC for the same dates and channels. If actual CAC is higher, identify whether conversion, average order value, margin or spend is different rather than simply raising the target. A CAC calculator is useful for changing one assumption at a time.

Use the output as operating rules: a target CAC is the ceiling for planned acquisition, actual CAC is the measure for reviewing performance, and marginal CAC is the measure for deciding whether to add the next dollar of spend. Set a lower test threshold, a review range and a stop rule; increase budget only when incremental customers remain inside the ceiling after the measurement window.

A sustainable CAC is not a universal industry figure: it is the highest amount your store can recover from the margin and repeat behaviour its own customers produce. Use first-order contribution to protect cash flow, customer-level payback to assess retention, and channel-level results to decide where additional budget is justified.
