Loyalty programmes with status levels produce a distinctive pattern of behaviour. Almost all of the additional spending they generate happens close to a threshold.

The reward arrives in a step

Tier benefits are granted in full once a threshold is crossed rather than accumulating gradually, which makes the value of the final unit of spending enormous.

A member just short of a level faces a small remaining requirement standing between them and a year of benefits, which is a very strong incentive.

A member far from the next level faces the same benefits at a much greater cost, and behaves as though the tier does not exist.

Progress must be visible to work

The mechanism depends entirely on members knowing where they stand, which is why programmes display progress prominently and prompt as periods end.

Without that visibility the threshold cannot influence a decision, since the member has no way to know that a small amount of spending would cross it.

The strength of the effect is therefore partly a function of how well the programme communicates, not only of how generous the tiers are.

Qualifying periods reset the incentive

Most schemes require the threshold to be met again within each period, which restores the incentive rather than allowing status to be earned permanently.

Reset dates create a concentrated burst of activity as members complete their requirement, followed by a quiet interval at the start of the new period.

Some programmes soften this with rollover or extension arrangements, which reduces the spike but also weakens the deadline that produced it.

Status is valued beyond its contents

Tier benefits often have modest direct value, yet members pursue them well past the point where the spending is justified by what is received.

Part of what is being bought is recognition and differentiated treatment, which has value that is not captured by adding up the individual benefits.

This is why programmes emphasise visible markers of status, and why removing such markers tends to produce a stronger reaction than reducing tangible benefits.

Costs concentrate where behaviour did not change

Members who would have reached a tier regardless receive the benefits without changing anything, and that is where most of the programme's cost falls.

The effect the programme is designed to produce occurs only among members near a threshold who would otherwise have fallen short.

Setting thresholds is therefore a balance between placing them where enough members can be moved and avoiding a level that large numbers reach anyway.
