Most loyalty programs reward customers for what they have already done. Better loyalty programs reward customers for what the brand wants them to do next.
That might mean making a second purchase, trying a new category, returning sooner, referring a friend, completing product education or increasing share of wallet.
The difference sounds small.
Commercially, it is enormous.
Because the real question behind loyalty program ROI is not:
“Did this customer buy?”
It is:
“Would this customer have bought anyway?”
The problem with rewarding your best customers
Imagine you run a coffee chain.
One customer visits you five mornings every week.
You introduce a loyalty program and start giving them points for every cup.
At the end of the month, they have earned free coffee.
Your loyalty dashboard looks excellent.
High engagement.
High frequency.
High redemption.
High member spend.
There is just one awkward question.
Did the loyalty program change anything?
If that customer was already going to visit five times a week, you may simply have given away margin on purchases you would have received anyway.
That does not mean loyal customers should not be recognized.
It means recognition and behavioral incentives are two different jobs.
And too many loyalty programs confuse them.
What should a loyalty program actually reward?
A loyalty program should ideally reward incremental behavior, meaning behavior that probably would not have happened without the intervention.
Examples include:
- turning a first-time customer into a second-time buyer
- getting an occasional buyer to purchase more frequently
- encouraging someone to try another product category
- recovering a customer who has stopped buying
- generating a genuine referral
- increasing a retailer’s range or secondary sales
- encouraging product training or participation
- getting customers to provide verified purchase information
- moving purchases toward a strategically important product or channel
The reward is not the objective.
The behavior is the objective.
The reward is one of the tools used to influence it.
That distinction should shape the entire program.
Why traditional loyalty metrics can be misleading
Loyalty teams understandably monitor transactions, points issued, redemptions, active members and member revenue.
Those numbers matter.
But they cannot always tell you whether the program caused the behavior.
BCG made this point particularly clearly in its July 2026 work on incrementality. It found that organizations using rigorous testing frequently discover that 20% to 40% of active marketing programs produce marginal or negative incremental lift, even though customers respond to them.

In other words, an offer can produce a conversion without actually causing the conversion.
Suppose you send a ₹500 reward to 10,000 customers who are statistically your most likely buyers.
A large percentage subsequently purchases.
The campaign looks successful.
But you selected people who were already highly likely to purchase.
How much of that revenue did the reward actually create?
Without a control group or another credible method of measuring incrementality, you may not know.
Loyalty ROI should start with one question
Before designing a reward, ask:
What behavior are we trying to change?
Not:
“What reward should we give?”
Not:
“How many points should customers earn?”
Not:
“Should we give vouchers or cashback?”
Those questions come later.
Start here:
What would we like this customer to do that they are unlikely to do without some intervention?
Once that behavior is clear, the incentive becomes much easier to design.
McKinsey has previously found that top-performing loyalty programs can increase revenue from customers who redeem points by 15% to 25% annually through increased purchase frequency, basket size, or both.
But the same research also warned that many established loyalty programs fail to create value.
The opportunity is therefore not to abandon loyalty.
It is to make loyalty more precise.
The RewardPort Incremental Behavior Model
A useful way to design a program is to move through five questions.
1. Baseline: What is the customer already doing?
Start by understanding normal behavior.
If a customer already purchases every week, simply rewarding the weekly transaction may add very little.
If another customer purchases once every three months, getting that person to return in six weeks represents a potentially meaningful behavioral change.
Without a baseline, almost every subsequent loyalty metric becomes harder to interpret.
2. Behavior: What do we want them to do next?
Define one specific action.
For example:
Consumer
First purchase → second purchase
Retailer
Stocks three SKUs → stocks five SKUs
Dealer
Registers → completes product training
Customer
Buys product A → tries product B
Dormant member
No purchase for 90 days → returns
Advocate
Happy customer → verified referral
Each creates a clearer reason for rewarding someone.
3. Friction: Why aren’t they doing it already?
Customers do not always need more money.
They may need:
- a reminder
- greater convenience
- recognition
- information
- reassurance
- progress toward something
- excitement
- access
- status
- a relevant experience
BCG’s loyalty research has similarly found that customers value more than monetary rewards alone and that relevance and experience influence program satisfaction.

This is why automatically increasing cashback is not always the answer.
4. Incentive: What is the smallest meaningful intervention?
Only now should you choose the reward.
Different behaviors may call for very different incentives.
A ₹20 instant reward might be enough to encourage a small verified action.
A high-value experience might be better for a meaningful milestone.
Recognition may work better than cash for another audience.
A retailer challenge could combine progress, competition and a payout.
The objective is not to give the biggest reward.
It is to create enough perceived value to change behavior while maintaining attractive program economics.
5. Incrementality: Did behavior actually change?
Finally, measure the difference between:
What happened
and
What would probably have happened anyway.
This can be evaluated using holdout groups, controlled tests, matched audiences, historical baselines or more sophisticated modelling depending on the scale and sophistication of the program.
That is a better definition of loyalty ROI.
Recognition and incentives should not be confused
There is an important qualification to the headline of this article.
Your best customers absolutely deserve recognition.
They may deserve better service, priority access, exclusive experiences, status or surprise benefits.
That reinforces the relationship.
But constantly discounting every transaction of your most loyal customer is something else entirely.
Think of it this way:
| Customer situation | Traditional approach | Behavior-led approach |
|---|---|---|
| Already buys weekly | Give points every week | Recognize loyalty, then incentivize a new behavior |
| Buys one category | Reward same purchase | Reward trial of an adjacent category |
| High-spending dealer | Increase payout | Incentivize range, training or secondary sales |
| Dormant customer | Generic points | Give a targeted return mission |
| New customer | Reward first purchase heavily | Put stronger incentive behind the second purchase |
| Advocate | Give another purchase discount | Reward a verified referral |
The best programs can do both.
Recognize existing loyalty. Create incentives for incremental behavior.
Stop treating every customer action as equally valuable
Consider two customers.
Customer A spends ₹50,000 every year and would probably continue doing so without your loyalty program.
Customer B spends ₹10,000 but could realistically spend ₹20,000 if the brand could win a greater share of their purchases.
Which one deserves more incentive investment?
The obvious answer is not necessarily Customer A.
A smarter loyalty strategy looks at incremental opportunity, not simply historical spend.
That might mean allocating greater incentive budgets toward:
- customers close to making a second purchase
- customers whose frequency can realistically increase
- cross-category opportunities
- dormant but recoverable customers
- high-potential channel partners
- referrals with a high probability of converting
Loyal customers remain valuable.
But loyalty investment should follow opportunity, not habit.
Cashback is not the problem
Cashback is often criticized as being transactional.
That criticism misses the point.
Cashback can be extremely effective when attached to the right behavior.
So can points.
So can merchandise.
So can vouchers, movies, experiences, travel benefits, status or recognition.
The real question is:
What behavior is this reward buying?
₹100 cashback for a purchase someone was already going to make is very different from ₹100 cashback that causes a customer to try a new SKU, return sooner or complete a verified action.
The reward instrument may be identical.
The economics are completely different.
A simple loyalty ROI formula
At a basic level, brands should think about:
Incremental Value Created
minus
Reward Cost + Program Cost
= Incremental Program Contribution
The difficult part is not calculating the cost.
The difficult part is identifying the incremental value.
BCG has long argued that loyalty economics ultimately depend on whether the incremental margin generated by a program exceeds the cost of providing the benefits.
This is why redemption rates alone cannot tell you whether a loyalty program is working.
Neither can enrolments.
Neither can member revenue.
They describe activity.
Not necessarily causality.
What should loyalty teams measure instead?
The precise metrics depend on the objective, but useful measures can include:
Behavior metrics
- Purchase frequency
- Time to second purchase
- Category penetration
- Dormant customer reactivation
- Referral conversion
- Retailer range expansion
- Training completion
- Target achievement
Commercial metrics
- Incremental revenue
- Incremental gross margin
- Cost per incremental action
- Reward cost
- Customer lifetime value change
- Incremental share of wallet
Engagement metrics
- Participation
- Redemption
- Challenge completion
- Repeat engagement
- Reward preference
Control metrics
- Fraud rates
- Duplicate claims
- Invalid invoices
- Suspicious redemption behavior
- Cost leakage
The question behind every dashboard should remain the same:
What changed because the program existed?
What does this mean for consumer promotions?
Exactly the same principle applies.
A consumer promotion should not merely generate claims.
It should have a defined behavioral job.
For one brand, that might be trial.
For another, repeat purchase.
For another, collecting first-party consumer data.
For another, increasing basket size.
For another, driving referrals.
For another, moving customers toward a premium product.
QR codes, OTP validation, invoice parsing, cashback, gamification and rewards are the execution tools.
They should not become the strategy itself.
Where RewardPort fits
RewardPort’s approach to consumer promotions, loyalty and channel engagement begins with the behavior a brand wants to influence, then connects verification, engagement and an appropriate reward mechanism around it.
Depending on the program, qualifying actions can be validated through mechanisms such as QR, OTP, invoices, OCR or other approved transaction data.
Rewards can then range from cashback and vouchers to merchandise, cinema, travel and experiences.
The objective is not simply to issue rewards.
It is to build a measurable loop:
Define behavior → verify action → reward intelligently → measure response → improve the next intervention.
That is where loyalty begins to become growth infrastructure rather than an expense line.
The final question
Before approving your next loyalty campaign, remove the points, vouchers, cashback and rewards from the presentation.
Then look at what remains.
Can you clearly complete this sentence?
“We are investing in this program because we want this customer to ______.”
If the answer is not immediately obvious, the program probably needs more work.
Because the future of loyalty is not about rewarding more behavior.
It is about knowing which behavior is actually worth rewarding.
Frequently Asked Questions
Should brands stop rewarding loyal customers?
No. Loyal customers should be recognized and retained. The argument is against automatically paying customers for behavior they would have demonstrated anyway. Recognition and incremental behavioral incentives should be designed separately.
What is incremental behavior in loyalty?
Incremental behavior is an action that probably would not have happened, or would have happened less frequently, without the loyalty intervention. Examples include an additional purchase, category trial, referral, reactivation or increased frequency.
How do you measure loyalty program ROI?
Measure the incremental commercial value created by the program and compare it with reward, technology, operational and fulfilment costs. Where practical, controlled testing or credible comparison groups should be used to estimate what customers would have done without the program.
Are loyalty points ineffective?
No. Points can work extremely well. Their effectiveness depends on what behavior they encourage, their perceived value, redemption experience and program economics.
Is cashback better than loyalty points?
Neither is universally better. Cashback provides immediate and easily understood value. Points can create progression and longer-term engagement. The right mechanism depends on the audience, behaviour and commercial objective.
What is the biggest mistake brands make with loyalty programs?
Starting with the reward instead of the behavior. A stronger program begins by defining precisely what the business wants the customer or channel partner to do differently.
