How to calculate CLV
A simple version: CLV = average order value × purchases per year × years as a customer × profit margin. A customer who spends 500 kr four times a year for three years, at a 40% margin, is worth 500 × 4 × 3 × 0.4 = 2,400 kr in profit.
More advanced models use real purchase data per customer, subtract the cost of serving them and discount future income.
Why CLV matters
- Marketing budgets: compare CLV with customer acquisition cost (CAC). A CLV of at least three times the CAC is a common target.
- Bidding: in Google Ads, value-based bidding can focus on customers who are worth more.
- Retention: keeping customers longer is often cheaper than finding new ones.
- Segmentation: spot your most valuable customers and what they have in common.
How to increase CLV
- Improve onboarding and customer service.
- Offer subscriptions, loyalty programs and relevant add-ons.
- Keep in touch with email and personalized offers.
Customer lifetime value is sometimes also called customer lifecycle value.
CLV example
A coffee subscription costs 200 kr a month. Customers stay on average 18 months, and the gross margin is 45%. CLV in profit is 200 × 18 × 0.45 = 1,620 kr. If it costs 500 kr to win a customer, each customer returns more than three times the acquisition cost. If a campaign costs 1,800 kr per customer, it loses money even though the sales look good.
How to raise customer lifetime value
- Improve the first 30 days with clear onboarding and quick support.
- Offer relevant add-ons and upgrades at the right moment.
- Reduce reasons to leave: fix recurring complaints and make billing clear.
- Keep in touch with useful email, not only offers.
- Reward long-term customers with real benefits.
CLV mistakes
- Using revenue when profit is what pays the bills.
- Using an average that hides very different customer groups. Calculate by segment.
- Assuming past retention will continue when the market changes.
- Forgetting the cost to serve customers, such as support and returns.
CLV FAQs
