The raw gap says $41.30 and the incremental figure says $8.17. Frequent buyers join loyalty schemes; the scheme does not create all of that frequency, and assuming it does justifies discounts that lose money.

How the Loyalty Discount Calculator works

Members buy more often partly because frequent buyers join loyalty schemes. Attributing the whole frequency gap to the discount is the standard error, and it justifies discounts that quietly lose money on the customers you would have kept anyway.

Also known as: member discount calculator · repeat customer discount · loyalty pricing calculator

Discounting the customers who already buy

A loyalty discount is given to customers who were going to buy anyway, which makes it a subsidy rather than an acquisition cost. That is not automatically wrong and it has to be understood.

The justification is retention: the discount increases the probability of the next purchase and the lifetime value of the relationship. Whether it does so by enough to cover the margin given away is an empirical question.

The measurement is repeat purchase rate among members against a comparable non-member group, and the difficulty is that members self-select. People who join loyalty programmes were already more loyal, so the raw comparison overstates the effect substantially.

Points, tiers and cashback

Points programmes accrue value slowly and defer the cost, which is good for cash and creates a liability. Redemption rates vary widely and unredeemed points are a benefit you paid nothing for and promised anyway.

Tiered programmes give escalating benefits at spend levels and work well where there is real variation in customer value. They also create a status effect that a flat discount does not.

Cashback or straight percentage discounts are the simplest and the least differentiated. They are easy to understand and easy to leave, since a competitor's slightly better percentage moves the customer. Programmes built on non-price benefits, early access, free shipping, exclusive products, are considerably stickier per pound spent.

Costing the programme properly

The visible cost is the discount given. The full cost includes the platform, the administration, the liability for unredeemed points, and the margin given up on customers who would have bought regardless.

That last item is usually the largest and it is the one never counted. If 70% of programme members would have made the same purchases without it, then 70% of the discount is pure cost.

The offsetting benefit is the behaviour change in the other 30%, plus the data. A loyalty programme that identifies customers across purchases is worth something for targeting alone, and that value is real even where the discount is not paying for itself.

The liability on the balance sheet

Points issued and not redeemed are an obligation, and under most accounting standards they have to be recognised as deferred revenue rather than ignored.

The estimate requires a breakage assumption: the proportion that will never be redeemed. Historic redemption data supports it and new programmes have to estimate, which means the early years' figures are unreliable.

The practical risk is a change in redemption behaviour. A programme running for years at 40% redemption that suddenly sees 70% because of a change in the offer has a materially larger liability, and the cash to honour it has to come from somewhere. Expiry rules limit this and are regulated in some jurisdictions.

Whether to run one at all

Loyalty programmes suit categories with frequent repeat purchase and low switching costs, where the marginal decision is genuinely between suppliers. Consumables, coffee, cosmetics, pet food.

They suit poorly categories with long replacement cycles, where the customer will not return for years and the points expire before they matter. Furniture, appliances, anything bought once.

The honest test is whether the repeat rate is high enough for a programme to have anything to work with. A business with a 15% repeat purchase rate is discounting the 15% who would have returned anyway, and would usually get more from spending the same money on the product or on acquisition.

Where to go next

The Loyalty Discount question rarely arrives on its own. These are the ones that usually come with it:

Loyalty Program ROI Calculator — Members spend more partly because loyal people join.
Loyalty Tier Threshold Calculator — Benefits go to everyone above the line.
VIP Customer Threshold Calculator — Losing one costs several ordinary customers.
Etsy Fee Calculator — Every Etsy fee on one sale, itemised.

Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price, check the platform's current fee schedule before you price a product against it. This is not tax or business advice.

Frequently asked questions

Is a permanent member discount worth it?

Only if it genuinely increases frequency. A discount to customers who already buy every month is a price cut with a loyalty label on it.

How do I measure the real effect?

Compare cohorts before and after joining, or hold out a group from the offer. The raw member-versus-non-member comparison is dominated by self-selection.

What works better than a discount?

Early access, free shipping, better service, and anything that costs you less than its perceived value. Discounts are the most expensive loyalty currency available.
