The LTV Models You'll Actually Use

FAQ

• What is customer lifetime value (LTV) and why does it matter for SaaS businesses?

  Customer lifetime value (LTV) is the total revenue a SaaS business can expect from a single customer before they churn.
  
  CLV measures the total net revenue a business can expect from a single customer relationship, linking retention directly to long-term profitability. For subscription businesses, LTV is a lighthouse metric because it tells you how much you can afford to spend acquiring each new customer. If your LTV is low relative to your customer acquisition cost (CAC), your growth engine is leaking before it even gets started. Tracking LTV by pricing tier or customer segment gives you the sharpest picture of which parts of your business are actually healthy.
• What is the difference between LTV based on revenue churn versus user churn?

  Revenue churn LTV measures how long customer revenue lasts, while user churn LTV measures how long individual customers stay subscribed.
  
  The distinction matters because the two models serve different business models. Revenue churn LTV is better suited to B2B SaaS companies with tiered pricing, upsells, and expansion revenue, where a customer can shrink or grow their spend over time. User churn LTV works better for B2C subscription products or flat-rate pricing, where every active subscriber is worth roughly the same amount. Choosing the wrong model can lead you to misread your unit economics and misallocate marketing or retention budget.
• What is the formula for calculating LTV in a subscription business?

  The core LTV formula for subscription businesses is: LTV equals ARPU (average monthly recurring revenue per user) multiplied by average customer lifetime.
  
  Customer lifetime is itself derived from your churn rate: if your monthly churn rate is 2%, average customer lifetime is 50 months. From there, LTV is simply your ARPU multiplied by that figure. For a more accurate picture, you can layer in gross margin (margin-adjusted LTV) or a discount rate to account for the time value of money (discounted cash flow LTV). Baremetrics calculates these figures automatically from your Stripe data, so you are not doing this arithmetic in a spreadsheet every month.
• What is a discounted cash flow LTV model and when should SaaS companies use it?

  A discounted cash flow (DCF) LTV model adjusts standard lifetime value calculations to reflect the fact that future revenue is worth less than revenue earned today.
  
  Traditional LTV models treat a dollar received in month one the same as a dollar received in month 36, which overstates the real value of long-term customer relationships. The DCF approach applies a discount rate to future cash flows, giving a more realistic view of what each subscriber is actually worth in present-day terms. This model is most useful for late-stage SaaS companies with predictable revenue, and for founders or CFOs preparing unit economics for investor diligence. The LTV to CAC ratio is a favorite compound metric for SaaS investors, and DCF LTV makes that ratio more defensible.
• How do you use LTV by segment to improve your ideal customer profile (ICP)?

  Segmenting LTV by pricing plan, acquisition channel, or customer type reveals which customer groups drive the most long-term revenue and stay the longest.
  
  

  • Break your subscriber base into cohorts by plan tier, billing interval, or company size.
  • Compare average LTV and churn rate across each segment to spot the stickiest groups.
  • Identify what your highest-LTV customers have in common, then use that to sharpen your ICP.
  • Shift acquisition and onboarding focus toward channels and messaging that attract those profiles.

  Lower-priced plans typically carry higher churn and lower LTV, so doubling down on segments that already show strong retention is usually more efficient than trying to fix high-churn cohorts after the fact.
• What is a margin-adjusted LTV model and why do investors prefer it?

  A margin-adjusted LTV model calculates customer lifetime value after accounting for gross margin, showing the true profit contribution of each customer rather than just top-line revenue.
  
  Standard LTV figures can be misleading because they ignore the cost of serving each customer. Factoring in gross margin gives you a number that reflects what actually flows to the bottom line over a customer relationship. The LTV to CAC ratio is best evaluated in the context of company size and ACV, and investors consistently prefer margin-adjusted figures because they reveal whether a business is genuinely profitable at the unit level. For B2B SaaS companies with tiered pricing and upsell motion, this model gives the most honest read on unit economics.
• How do you track LTV month over month without a dedicated analytics tool?

  You can track LTV month over month manually by maintaining a Google Sheet that logs ARPU, churn rate, and customer lifetime for each billing period.
  
  

  • Record monthly ARPU and your churn rate for each pricing tier separately.
  • Calculate customer lifetime by dividing one by your churn rate for each segment.
  • Multiply ARPU by customer lifetime to get LTV, then log it each month to spot trends.
  • Add a gross margin column to shift toward margin-adjusted LTV as your data matures.

  Manual tracking works when you are early-stage and volumes are low, but it gets brittle fast. Baremetrics pulls this data directly from Stripe and surfaces LTV, ARPU, and churn in real time, so you can stop rebuilding the same spreadsheet every month.
