Key takeaways
A subscription business marketing budget should be set from what each subscriber earns before they cancel. Multiply monthly gross profit per subscriber by the months you can wait to be repaid, then check churn makes that wait realistic. That gives the most you can pay per subscriber, and the social budget follows.
- Max cost per subscriber = monthly gross profit × payback months.
- £12 monthly profit × 6 months = £72 per subscriber.
- High churn shortens the safe payback period.
- Cancellation must be easy under UK subscription rules.

Find monthly gross profit per subscriber after product, delivery and payment fees. Choose a payback period you can fund, often three to twelve months. Illustrative example: £12 a month of profit and six months' payback means you can pay up to £72 to win a subscriber.
How does churn change the budget?
If many subscribers cancel in the first months, few stay long enough to repay you. Check what share are still subscribed after your payback period. If most leave sooner, shorten the payback period, lower the cost you will pay, or improve retention before spending more.
Send us your churn and monthly profit on WhatsApp and we will discuss your requirements.
Chat on WhatsApp →What should the social budget pay for?
Ads that explain the subscription clearly, including price and how to cancel; content that shows the product in use; and retargeting for people who visited but did not join. Introductory offers can lift sign-ups but often raise churn, so measure retention by offer.
Which rules apply to subscriptions?
Consumer law requires clear information about price and renewal, and the Digital Markets, Competition and Consumers Act 2024 introduces a specific subscription regime, including reminders and easy cancellation, with commencement dates to confirm. Ads must not hide renewal terms. Check current guidance before launching offers.
What does this look like in practice?
A pattern we see: a subscription brand pays for sign-ups with a deep first-month discount, and many cancel after it. Measuring retention by offer usually shows a smaller discount brings fewer but longer-lasting subscribers and a lower true cost per subscriber.
Subscription budget checklist
- Calculate monthly gross profit per subscriber.
- Pick a payback period you can fund.
- Check retention over that period.
- Measure retention by offer.
- Show price, renewal and cancellation clearly.

Frequently asked questions
How much should a subscription business spend to get a customer?
Up to the gross profit a subscriber produces over a payback period you can fund, adjusted for how many cancel before then. For example, £12 a month of profit over six months allows up to £72. Lower it if many subscribers leave early.
What is CAC payback?
CAC payback is how many months it takes for a customer's gross profit to repay what you spent to acquire them. Divide acquisition cost by monthly gross profit per customer. Shorter payback needs less cash to fund growth. Review it each quarter against your enquiries and sales, and adjust in small steps.
Do discounts help subscription growth?
They can lift sign-ups, but deep introductory discounts often attract people who cancel when the price rises. Measure retention by offer, not just sign-ups, and compare the true cost per retained subscriber before choosing which offers to scale. Review it each quarter against your enquiries and sales, and adjust in small steps.
