Programme Design
Loyalty programme economics
Assess a loyalty programme using additional contribution, reward costs, points commitments and realistic redemption scenarios.
A loyalty programme makes economic sense when the additional contribution it generates covers its rewards and running costs. Start with the behaviour the offer is meant to change, then compare the forecast with what customers might have done without it. Member sales alone do not show programme impact.
Build the business case around contribution
For planning, contribution is sales revenue less costs that change with those sales: product, payment and delivery costs. Treat GST and returns consistently across scenarios. Compare the change in contribution with additional programme costs over the same period. Keep reward costs separate from costs already deducted from sales, to avoid double counting.
Estimated additional contribution − additional reward and programme costs = estimated net programme contribution.
An order from a member is not automatically an additional order. A reward can also reduce contribution from a purchase the customer would have made anyway.
| Question | What to estimate |
|---|---|
| What might change? | Additional purchases, larger baskets or purchases retained that would otherwise be lost. |
| What is given away? | Discounts, products, shipping, partner payments and service benefits members use. |
| What must be run? | Software, staff time, support, communications and added capacity. |
| What remains promised? | Earned points and other benefits still available under the terms. |
Model a case with little or no behavioural change before relying on a more favourable forecast.
Contribution Impact: With vs Without Loyalty Programme
- Contribution from Member Sales (With Programme)
- Estimated additional contribution after rewards and programme costs
- Contribution from Same Sales (Without Programme)
- Base contribution without loyalty incentives
- Net Programme Contribution
- Difference between the two above (should be positive for economic viability)
Estimate reward costs
A reward’s advertised value is not necessarily its cost. A discount reduces receipts on an otherwise identical basket.
A free product uses stock and fulfilment resources and may displace a paid sale. Free delivery can add delivery costs and forgo a charge the customer would otherwise have paid. A partner reward depends on the contract and who handles claims and fulfilment.
Calculate each reward’s cost under the proposed rules. Show any lost contribution from a displaced sale as a separate scenario. Do not add both a product’s full selling price and the lost contribution from that same sale.
A low-cost reward still needs to be attainable and available when members try to use it. A costly reward may be viable if it produces enough additional contribution; that effect needs evidence, not an assumption in the forecast.
Key Loyalty Programme Cost Components
- Discounts Given
- Reduced revenue per transaction; affects GST and margin
- Free Products or Services
- Cost of goods + fulfilment; may displace paid sales
- Delivery Costs (Free Shipping)
- Additional logistics cost; loss of charge otherwise paid
- Partner Reward Fulfilment
- Depends on contract terms; may include admin and claims handling
Forecast earning and redemption separately
Points awarded today may be used later, reversed after a return or remain unused. Forecast points earning, reversals, redemptions and expiry at a high level; for detailed points-ledger modelling, see the supporting article.
Forecast which rewards members might choose as well as how many points they might use. The same points balance can lead to different costs depending on the reward mix. Include a higher-use case; the offer should not depend on members failing to use promised benefits.
Keep this operating forecast separate from financial-statement accounting; refer accounting treatment questions to the finance team.
Steps to Forecast Loyalty Programme Economics
- Forecast Points Earning RateBased on customer behaviour and earn rules
- Estimate Redemption PatternsInclude timing, reward choice, and point expiry
- Model Reward Mix CostDifferent rewards have different cost structures
- Calculate Net ContributionAfter all rewards, costs, and foregone sales
Check the affected orders
Examine both the basket that earns points and the basket that uses them. A low-margin purchase can generate points for a future reward. At redemption, discounted items, another promotion or delivery costs can reduce contribution further.
Compare contribution from an eligible basket before and after the reward, then consider whether the purchase was likely to be additional. If it would have happened anyway, a discount gives away margin.
If it was prompted by the offer, assess its contribution after reward and fulfilment costs. Include returns and partial refunds in both cases.
Set a contribution floor for affected orders, a programme spending limit and a review trigger if use or support costs exceed the forecast. The figures are business decisions, not universal thresholds.
Pros and Cons of High-Value Rewards in Australian Retail
- ProsCan drive significant behavioural change and increase engagement; useful for acquiring high-value customers
- ConsHigh cost risk if not tied to real incremental sales; can erode margins if used on non-additional purchases
Review scenarios and actual results
Vary the assumptions that matter most: behavioural change, earning, redemption, reward choice and fulfilment cost. Record the period and customer group behind each assumption.
After launch, reconcile points and claims with transaction records and compare actual costs with the forecast. Where feasible, use a credible comparison to assess impact: people who join may already buy more often. Without one, describe observed results without calling all member sales incremental.
If the economics fail, review the earn rate, reward, eligibility or fulfilment route while accounting for benefits members have already earned.
Consumer reports can also flag issues for a programme review, but they are not a route to individual complaint resolution.
Pre-Launch Loyalty Programme Economics Review Checklist
- Confirm behavioural change assumptions are realisticNot all member activity is incremental
- Verify redemption forecasts include high-use scenariosAvoid over-reliance on unused points
- Ensure partner reward costs are accurately modelledAccount for claims handling and fulfilment responsibilities
- Set contribution floor and spending limitsProtect against margin erosion
