How to Measure Loyalty Programme Performance

Key Takeaways

• Sign-ups alone do not prove loyalty programme success.
• Track repeat purchases, purchase frequency and retention.
• Redemption rate shows whether rewards are appealing.
• Compare members with non-members to measure impact.
• Weigh programme costs against added sales and customer value.

A loyalty programme can look successful on the surface. Thousands of customers may have signed up, points may be issued every day and promotional messages may receive plenty of clicks.

But are members actually returning more often?

Are they spending more than non-members? 

Are they redeeming rewards? 

More importantly, is the programme generating enough additional business to justify the discounts, rewards and operating costs involved?

Measuring loyalty programme performance means looking beyond membership numbers and focusing on how customer behaviour changes over time.

 

What Does a Successful Loyalty Programme Actually Look Like?

A café might want customers to return several times each month, while a furniture retailer may only expect repeat purchases a few times a year. A beauty retailer may prioritise purchase frequency, while another business could be more interested in increasing average spending.

Before measuring anything, decide what the programme is supposed to achieve.

Common goals include:

• Increasing Repeat Purchases: Encouraging customers to come back instead of choosing a competitor.
• Increasing Purchase Frequency: Getting existing customers to buy more regularly.
• Increasing Spending: Encouraging customers to spend more per transaction.
• Improving Retention: Keeping customers active for longer.
• Encouraging Engagement: Getting members to redeem rewards, use an app or participate in gamification campaigns or promotions.
• Building Customer Value: Increasing the total amount customers spend with the business over time.

Once the goal is clear, the right measurements become much easier to identify.

1. How Many Members Are Actually Active?

Membership numbers are useful, but they can also be misleading.

Suppose 50,000 people have joined your loyalty programme. That sounds impressive. But if only 6,000 members have made a purchase or redeemed a reward in the past six months, your active member base is considerably smaller.

This is why businesses should distinguish between total members and active members.

An active member could be someone who has made a purchase, earned points, redeemed rewards or interacted with the programme within a defined period.

What counts as "active" depends on the business.

A Malaysian café chain may look at activity within the past 30 or 60 days because customers purchase frequently. A furniture or electronics retailer may need a much longer measurement period.

Tracking active members helps show whether customers are continuing to use the programme rather than simply signing up once and forgetting about it.

 

2. Are Loyalty Members Buying Again?

Repeat purchase rate is one of the clearest ways to measure loyalty because it looks at what customers actually do.

The basic calculation is:

Repeat Purchase Rate = Repeat Customers ÷ Total Customers × 100

If 2,000 customers bought from your business during the year and 700 purchased more than once:

700 ÷ 2,000 × 100 = 35% repeat purchase rate

For a loyalty programme, it is even more useful to compare:

A gap like this suggests members are more likely to return.

Loyalty performance should be viewed across several measurements rather than relying on one figure alone. Repeat purchase rate is widely regarded as an important retention measure because it tracks actual customer behaviour.

 

3. How Often Do Members Buy?

Repeat purchase rate tells you whether customers return. Purchase frequency tells you how often they return.

The basic calculation is:

Purchase Frequency = Total Purchases ÷ Number of Unique Customers

Imagine your loyalty members made 24,000 purchases during the year and you had 8,000 active members.

That gives you:

24,000 ÷ 8,000 = 3 purchases per member

You can then compare this against several criteria.

For example:

• Loyalty members this year: 3.4 purchases per year
• Non-members this year: 2.1 purchases per year
• Loyalty members last year: 2.9 purchases per year

Purchase frequency is particularly useful for Malaysian F&B outlets, supermarkets, pharmacies, retailers and ecommerce businesses where customers have plenty of alternatives and may purchase regularly.

 

4. Are Members Spending More?

Another useful measurement is average order value, often shortened to AOV.

The calculation is straightforward:

Average Order Value(AOV) = Total Sales ÷ Number of Transactions

Suppose loyalty members generate RM500,000 from 10,000 purchases.

Their average order value would be:

RM500,000 ÷ 10,000 = RM50

If non-members spend an average of RM38 per transaction, loyalty members appear to be spending more.

However, businesses should be careful when interpreting this figure.

A higher AOV is positive only if it makes commercial sense. Offering a RM20 voucher to encourage an extra RM10 of spending would obviously not be particularly useful.

Average spending should therefore be considered alongside the cost of rewards and promotions.

 

5. Are Customers Actually Using Their Rewards?

A loyalty programme is not very useful if customers collect points but never do anything with them.

This is where redemption rate becomes important.

A simple version of the calculation is:

Redemption Rate = Rewards Redeemed ÷ Rewards Earned × 100

Redemption rate provides an indication of whether customers find the rewards valuable and achievable.

A very low redemption rate could suggest several problems:

• Rewards take too long to earn.
• Customers do not understand how the programme works.
• Available rewards are not attractive.
• Points expire too quickly.
• Members forget that they have points.
• Redeeming rewards requires too many steps.

It is worth remembering that an extremely high redemption rate is not automatically better either. If rewards are too generous, the programme could become expensive without producing enough additional purchases.

The aim is to create rewards that customers genuinely want while keeping the programme commercially sustainable.

 

6. How Many Customers Are You Retaining?

Customer retention measures how successfully a business keeps its existing customers over time. A basic retention calculation is:

Customer Retention Rate = (Customers at End of Period − New Customers Acquired) ÷ Customers at Start of Period × 100

Suppose you started the year with 5,000 existing customers.

At the end of the year, you had 5,500 customers, of whom 1,500 were new.

Your retained customer base would therefore be 4,000.

4,000 ÷ 5,000 × 100 = 80% retention

Tracking retention among loyalty members can help businesses see whether membership is associated with longer customer relationships.

Retention is commonly measured alongside repeat purchases, purchase frequency and customer lifetime value when assessing customer loyalty.

 

7. How Much Revenue Comes From Loyalty Members?

Businesses should also understand how much of their total sales come from loyalty programme members.

For example, if members generate RM1.2 out of every RM2 in annual sales:

Member Revenue Contribution = 60%

You can then compare this with the percentage of customers who are members.

Suppose only 35% of customers are loyalty members but they contribute 60% of sales. That tells you the member segment is commercially important.

These figures help turn the loyalty programme from a marketing activity into something that can be evaluated in business terms.

 

8. What Does the Loyalty Programme Cost?

A programme can increase sales and still perform poorly if it costs too much to operate.

Businesses should account for more than the face value of rewards.

Costs may include:

• Discounts and vouchers
• Free products
• Cashback
• Loyalty software
• App or system costs
• Marketing campaigns
• Staff or administrative costs

You can then compare the programme's costs against the additional revenue or profit generated by loyalty members.

For smaller businesses, a simple question can be useful:

Are customers spending enough to justify what we spend rewarding them?

If the answer is unclear, the programme may need to be adjusted.

 

Compare Members With Non-Members

One of the most useful loyalty measurement practices is to avoid looking at members in isolation. Instead, compare them against customers who have not joined.

Look at differences in:

Industry guidance commonly recommends comparing loyalty members with non-members when evaluating changes in repeat purchases, spending and customer value.

This comparison can reveal whether your loyalty programme is attracting valuable repeat customers or simply giving discounts to customers who would have purchased anyway.

 

Do Not Measure Everything at Once

Businesses can easily end up with dashboards containing dozens of loyalty figures.

Start with a small set of measurements tied directly to what you want the programme to achieve.

For many retail, ecommerce and F&B businesses, five metrics are enough to begin:

1. Current Active Members
2. Repeat Purchase Rate
3. Average Spend
4. Reward Redemption Rate

You can then add other metrics such as retention, customer lifetime value and programme profitability as your data becomes more reliable.

The objective is not to collect as many numbers as possible. It is to identify numbers that help you decide what to improve.

 

How Often Should Loyalty Programme Performance Be Reviewed?

For most businesses, a monthly overview with a more detailed quarterly review is a reasonable starting point.

A monthly review can identify sudden changes such as falling reward redemptions or declining member activity.

A quarterly review gives you a better view of longer-term behaviour, including repeat purchases and spending.

Avoid judging a programme based on a few weeks of data.

Malaysia also has several major seasonal shopping periods, from Chinese New Year and Hari Raya to Deepavali, Christmas, 11.11 and 12.12 campaigns. Promotions during these periods can temporarily affect spending and redemption patterns.

Comparing a promotional month against a normal month can therefore give the wrong impression.

 

What Are the Warning Signs of an Underperforming Loyalty Programme?

Poor loyalty performance does not always mean the entire programme needs to be replaced.

Sometimes one part simply needs improvement.

Common warning signs include:

• Membership continues growing but active members are falling.
• Customers earn plenty of points but rarely redeem them.
• Most members only purchase when large discounts are offered.
• Members and non-members have almost identical purchase behaviour.
• Rewards cost more each year without improving repeat sales.
• The programme is difficult for customers to understand.

These patterns help show where to investigate.

For example, low redemption could indicate unattractive rewards, while strong redemption but weak repeat purchasing could suggest rewards are being claimed without changing long-term behaviour.

 

Summary

The best loyalty programmes do more than collect member registrations. They encourage valuable customer behaviour.

For most businesses, the clearest indicators are whether members return more often, spend more, stay customers for longer and actively use the rewards available to them.

Rather than relying on one figure, compare several measurements together and track how they change over time.

Most importantly, compare loyalty members with non-members and consider the cost of running the programme. A programme that has thousands of members is not necessarily successful. A smaller programme that consistently brings valuable customers back can be far more useful to the business. Finally, it always helps to have an efficient and seamless customer interaction program in conjunction with any loyalty program.
