Hvad er Customer Lifetime Value?
Hurtig definition
Lifetime Value (LTV eller CLV) er den samlede omsætning, en virksomhed kan forvente fra én enkelt kundekonto i løbet af hele forretningsforholdet.
Customer Lifetime Value predicts the total net profit from the entire future relationship with a customer. A simple formula is: Average Purchase Value × Purchase Frequency × Customer Lifespan = LTV. A customer who spends $50 per month for an average of 24 months has an LTV of $1,200.
More sophisticated LTV models account for profit margins, customer segments, cohort behavior, discount rates (time value of money), and upsell/cross-sell potential. SaaS companies often use Monthly Recurring Revenue ÷ Monthly Churn Rate as a quick LTV estimate.
LTV varies significantly across customer segments. Enterprise customers might have 10x the LTV of small business customers. Customers acquired through referrals often have higher LTV than those from paid ads. Understanding LTV by segment lets you allocate marketing spend where it produces the most value.
Increasing LTV is usually more profitable than acquiring new customers. Strategies include improving retention (reducing churn), increasing average order value (upsells, cross-sells), increasing purchase frequency (engagement, loyalty programs), and improving customer experience to extend the relationship lifespan.
Hvorfor det er vigtigt
LTV determines how much you can afford to spend on customer acquisition while remaining profitable. If your LTV is $1,200, spending $400 to acquire a customer is a great deal. If your LTV is $100, that same $400 is a path to bankruptcy.
The LTV:CAC ratio is the single most important metric for subscription and e-commerce businesses. It tells you whether your business model fundamentally works.
Eksempler fra den virkelige verden
A SaaS company calculated their LTV was $8,400 (average 28-month retention × $300/month) with a $1,200 CAC — their 7:1 ratio made them extremely attractive to investors
An e-commerce brand discovered their repeat customers had 5x the LTV of one-time buyers — they invested in a loyalty program that increased repeat purchase rates by 30%
A gym calculated average member LTV of $1,400 (14-month average membership × $100/month), justifying their aggressive $250 acquisition spend on signup promotions
A B2B software company segmented LTV by customer size and found enterprise customers had $50K LTV vs $5K for SMB — they restructured their sales team to focus on enterprise acquisition
