The standard SaaS formula multiplies average revenue per user by gross margin, then divides by churn rate, which is why lowering churn directly raises LTV. ## What does LTV mean? Customer lifetime value, or LTV, is an estimation of the net profit a customer contributes over the entire future relationship with a business. Per [Wall Street Prep](https://www.wallstreetprep.com/knowledge/lifetime-value-ltv/), the standard SaaS formula is average revenue per user multiplied by gross margin, divided by churn rate, which means [churn rate](https://builderscamp.com/guides/glossary/churn-rate-product) has a direct, multiplicative effect on LTV: a lower churn rate produces a longer average customer relationship and therefore a higher lifetime value, without any change to pricing. Other formulas exist for other business models, such as average transaction size multiplied by number of transactions and retention period, but the underlying goal is the same: estimate what one customer is actually worth over time, not just in a single transaction. ## Why LTV matters for product managers Business for Product Managers pairs LTV directly with [CAC](https://builderscamp.com/guides/glossary/customer-acquisition-cost) in its unit economics module, since the two numbers together, not separately, tell a PM whether a business model is sustainable. The bootcamp's certification quiz reinforces this pairing by testing unit economics as a connected system, not a list of isolated formulas. The bootcamp also teaches LTV as a moving target rather than a fixed input. A business case built on last year's LTV, before a pricing change or a churn reduction initiative, can understate or overstate the real return on a proposed investment. ## LTV example Business for Product Managers' practical challenge has a PM recalculate the financial impact of reducing churn at Cascade, a B2B SaaS company with an 18 percent annual churn rate and an average contract value of 14,100 dollars. Even without stating LTV explicitly, the exercise's core mechanic, showing how a churn reduction changes revenue retained and total annual impact, is the same underlying logic as an LTV calculation: less churn means more revenue collected per customer over time. Running the case with a conservative churn reduction of 0.8 percentage points instead of an optimistic 2 points shows how sensitive an LTV-driven business case is to the underlying churn assumption, which is exactly the kind of scrutiny the bootcamp wants a PM to apply before trusting a headline ROI number. ## How Builders Camp teaches LTV Builders Camp teaches customer lifetime value inside the [Business for Product Managers bootcamp](https://builderscamp.com/bootcamps/business-for-product-managers), directed by Andre Albuquerque, as part of its unit economics module covering CAC, LTV, margins, and payback together. Builders Camp runs live and self-paced bootcamps in product management and AI product building.

LTV equals average revenue per user multiplied by gross margin, divided by churn rate. A lower churn rate produces a higher LTV, since the customer relationship lasts longer on average. ### Why does LTV matter alongside CAC? Because the relationship between the two determines whether a business model is sustainable. An LTV to CAC ratio that is too low means the company spends more acquiring customers than it earns from them. ### Can LTV be calculated differently across companies? Yes. Some use average transaction size multiplied by number of transactions and retention period; others use the standard SaaS formula. The right formula depends on the business model's revenue pattern. ### Does LTV account for the cost of serving a customer? A more complete version does, subtracting the total cost to serve from average revenue per customer over the lifespan, rather than treating all revenue as profit. ### How does churn rate reduction affect LTV? Directly and multiplicatively, since churn rate sits in the denominator of the standard formula. A modest reduction in churn can meaningfully increase LTV without any change in pricing. ### Should LTV be treated as a fixed number? No. It should be recalculated regularly as churn, pricing, and margins change, since an LTV figure calculated a year ago on old assumptions can mislead a current business case. ## Sources - [Wall Street Prep: Customer Lifetime Value (CLV), Formula and Calculator](https://www.wallstreetprep.com/knowledge/lifetime-value-ltv/) ## How this guide was made Researched from Builders Camp's bootcamp, track and masterclass material and the sources listed on this page, drafted with AI, and fact-checked against every source cited.
