Customer Lifetime Value (CLV)
The total revenue a customer generates over their entire relationship with your business.
What is Customer Lifetime Value (CLV)?
Customer Lifetime Value (CLV or LTV) is the total net profit you expect from a customer over the entire duration of their relationship with your business.
Basic formula: CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan. For example: $200 average sale × 3 purchases/year × 4 years = $2,400 CLV.
CLV is crucial for determining how much you can afford to spend on customer acquisition. If CLV is $1,000, you might afford $300 CPA and remain profitable.
Increasing CLV is often more cost-effective than acquiring new customers. Strategies include: upselling, cross-selling, improving retention, increasing purchase frequency, and enhancing customer experience.
CLV in New Zealand Businesses
NZ service businesses with recurring revenue (subscriptions, retainers, repeat services) have higher CLV than one-time transaction businesses.
Calculate CLV conservatively for NZ market - account for churn, seasonal variations, and economic factors affecting NZ consumers.
Use CLV to justify marketing spend: if customer is worth $5,000 over 3 years, spending $500-800 to acquire them is reasonable.
NZ Business Examples
-
A NZ gym: $60/month membership × 18 months average retention = $1,080 CLV (can afford $250-350 CPA) -
An Auckland accounting firm: $3,000 annual fee × 7 years average client = $21,000 CLV (can afford $2,000-5,000 CPA) -
A subscription box service: $45/month × 11 months average = $495 CLV (should target $100-150 CPA)
Real-World Industry Examples
SaaS
A CRM company charges $149/month with 28-month average customer lifetime
CLV of $4,172 allows aggressive acquisition spending up to $1,200 CPA while maintaining healthy margins
E-commerce
An online pet supply store tracks repeat purchase behavior
First order $75, but 60% reorder 5x/year for 2.5 years = $938 CLV vs $60 initial CPA
Professional Services
A business coach offers 6-month program with 30% renewing for advanced program
Initial $6,000 program + $4,000 renewal (30% take) = $7,200 effective CLV enables $1,500 CPA

Frequently Asked Questions
How do I calculate CLV?
Basic CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan. More advanced: CLV = (Average Order Value × Purchase Frequency × Gross Margin) ÷ Churn Rate. Use historical data where possible.
What's a good CLV to CAC ratio?
Aim for 3:1 or better (CLV is 3x your CAC/CPA). A 3:1 ratio means healthy profitability. Below 3:1 suggests unsustainable acquisition costs. Above 5:1 might mean you're under-investing in growth.
How can I increase CLV?
Improve retention (reduce churn), increase purchase frequency (email marketing, loyalty programs), raise prices, upsell/cross-sell, improve product/service quality, and enhance customer experience. Retention improvements compound over time.
