The short answer: roughly 1,592 SAR per subscriber
For a car wash charging 199 SAR a month for an unlimited-wash subscription, with subscribers staying an average of 8 months, lifetime value works out to about 1,592 SAR per subscriber. That number has nothing to do with Waya's own 85 SAR Growth or 149 SAR Premium pricing — it's the wash's own subscription revenue, and it's the backdrop against which loyalty add-ons for subscribers should be judged.
For subscription customers specifically, a stamp card adds nothing — the subscription is already the retention mechanism. Loyalty spend for this segment should go toward add-on rewards like interior detailing on a points card, not toward re-earning something they've already paid for.
The LTV calculation
Two inputs are all this calculation needs, and both are entirely under the wash's own control — the subscription price it sets and how long the average subscriber sticks around before canceling.
| Input | Value |
|---|---|
| Monthly subscription price | 199 SAR |
| Average subscriber tenure | 8 months |
| Lifetime value per subscriber | 1,592 SAR |
| Waya Growth plan cost (unrelated to subscriber pricing) | 85 SAR / month, covers unlimited subscribers |
Working the math
The formula itself is simple multiplication; the harder part is getting a realistic tenure number, which is worth tracking on your own dashboard rather than guessing.
- Set the monthly subscription price
199 SAR, or whatever your own unlimited-wash plan charges.
- Estimate average tenure
8 months is a reasonable planning assumption; track your own churn to refine it.
- Multiply price by tenure
199 SAR x 8 months = 1,592 SAR lifetime value per subscriber.
- Compare against acquisition cost
Any subscriber acquisition spend under 1,592 SAR is profitable over their full tenure.
Why the reward strategy differs for subscribers
A points or add-on reward card for subscribers should reward behavior that isn't already covered by the subscription — detailing, interior cleaning, or seasonal extras — rather than stamping toward another free wash they'd get anyway. Waya's points and balance card types (available on Growth and Premium) suit this well, tracking add-on purchases separately from the unlimited-wash allowance.
The goal for this segment isn't pulling them back — the subscription already does that — it's increasing the average add-on spend per subscriber across their 8-month tenure.
How LTV changes with tenure and price
Small changes in either input move the final number more than they might seem to on first glance, which is worth knowing before assuming a price increase alone will fix a low LTV.
- A 149 SAR subscription at 6 months average tenure: 894 SAR LTV
- A 199 SAR subscription at 8 months average tenure: 1,592 SAR LTV
- A 249 SAR subscription at 10 months average tenure: 2,490 SAR LTV
- Longer average tenure moves LTV faster than a higher monthly price does, in most cases
Where Waya's own plan cost fits into this picture
None of the LTV figures above are affected by whether the wash is on Waya's Growth (85 SAR a month) or Premium (149 SAR a month) plan — those cover tracking unlimited customers, subscribers included, and are unrelated to what subscribers pay the wash. A wash with a few hundred subscribers at 1,592 SAR LTV each is comparing a very different scale of number against an 85 SAR monthly tool cost.

Why increasing add-on spend matters more than chasing tenure
Because a subscriber's base visits are already unlimited, the loyalty lever that actually moves revenue for this segment is add-on spend per visit, not visit frequency — a subscriber who adds a 40 SAR interior detail once a quarter contributes far more than one who simply washes more often at no extra charge. Tracking add-on purchases separately from the base subscription keeps that incremental spend visible on the dashboard rather than blending into overall visit counts.
This is also why a discount card rarely makes sense for subscribers: discounting a service that's already unlimited protects nothing, while a points card rewarding paid add-ons directly targets the spend that's actually incremental.
A limit worth knowing before building a subscriber add-on program
Waya has no POS or till integration, so an add-on purchase like a detailing service still needs a staff member to scan the subscriber's card on an ordinary phone to log points — the subscription billing itself happens outside Waya entirely. There's also no SMS channel; any add-on promotion to subscribers goes out as a wallet lock-screen message, not a text.
Frequently asked questions
How do I calculate lifetime value for a subscription car wash customer?
Multiply the monthly subscription price by the average number of months a subscriber stays. A 199 SAR subscription with 8-month average tenure gives a lifetime value of about 1,592 SAR.
Should a subscription car wash customer get a stamp card?
No. A stamp card rewards repeat visits, but a subscriber's visits are already unlimited and paid for. Use a points or balance card for add-ons like detailing instead.
Does Waya's plan cost affect subscriber lifetime value?
No. Waya's Growth (85 SAR/month) or Premium (149 SAR/month) plan cost covers tracking unlimited customers and is separate from what subscribers pay the car wash for their subscription.
What increases subscriber lifetime value the most?
Longer average tenure moves lifetime value more than a higher monthly price in most cases, since tenure compounds every additional month of revenue rather than a one-time increase.
Can Waya track subscription billing directly?
No. Waya has no POS or till integration and doesn't process subscription payments — it tracks add-on rewards like points for detailing, logged by staff scanning the card on an ordinary phone.
