Unit economics

The revenue and cost of a business measured for one unit, such as one customer, member or point, before fixed overheads.

Unit economics is the revenue and cost of a business measured for a single unit, such as one customer, one order or one product, before fixed overheads. In a loyalty program the unit is usually one member or one point, and fixed overheads are items like the platform license and the core team. It answers whether each additional unit adds value or costs money. If the unit economics are negative, growth makes the result worse, not better.

Understanding the termAll terms

What is the unit economics formula?

Contribution per unit = revenue per unit minus variable cost per unit. Contribution margin is that figure divided by revenue per unit. Fixed costs stay out because they do not rise with each extra unit. Whether a cost is variable matters more than its label: a per-member platform fee belongs in the calculation, while a flat license does not.

How does it relate to LTV and CAC?

Startups and subscription businesses often express unit economics as customer lifetime value compared with the cost of acquiring a customer, plus how long that cost takes to pay back. The logic carries over to loyalty, with one change: compare CLV that is based on margin rather than revenue, and count only the value the program adds. A ratio built on sales the customer would have made anyway looks healthy and says little. No benchmark fits every business, so compare your own cohorts over time.

Which unit should a loyalty program use?

Per member is the most common choice for programs funded from their own sales. It compares the extra margin a member brings with the cost of their rewards, benefits and communications. Per point suits programs that sell points to partners, because it compares the price received for a point with the cost of redeeming it. Many programs track both.

How do you calculate it per member?

Start with the incremental margin a member brings in a year, ideally measured against a control group. Subtract the expected cost of the points they earn, the cost of any benefits they use and the cost of reaching them. In a hypothetical program, an average member brings $60 of extra margin, earns points that will cost $25 and receives $10 of benefits and marketing. The contribution is $25 per member per year.

Why do averages mislead?

Because members differ widely. In the same hypothetical program, the top tier might contribute $80 per member while a large group of occasional members contributes nothing or less. The average can stay positive while a growing segment loses money, which is a cross-subsidy nobody decided on. Breaking unit economics down by tier, cohort and channel shows where value is created and where it leaks.

What changes unit economics without anyone noticing?

  • A higher breakage assumption, which lowers the expected cost per point on paper.
  • A shift in the reward mix toward more expensive rewards.
  • Tier benefits that become more widely used than planned.
  • Growth through promotions that attract members who join for one offer and never return.

Review unit economics at least once a year and before any change to earn rates, tiers or benefits.
