Maximizing ROI: Understanding Customer Lifetime Value (LTV) in SaaS

Read time: 3 minutes

Happy Monday!

In today’s essay, we will break down LTV in simple terms, covering its definition, the most commonly used formula, its limitations, and how factors like churn and account expansion play a pivotal role.

We'll also delve into a more advanced LTV formula by the distinguished SaaS metrics expert David Skok.

Without further ado, let’s get started.

What is Customer Lifetime Value or LTV?

In the dynamic world of SaaS, you've probably heard the buzzword "Customer Lifetime Value" or LTV thrown around quite a bit. But what exactly is LTV, and why does it hold such significance in the SaaS world?

At its core, Customer Lifetime Value (LTV) is like a crystal ball for businesses.

The magic number predicts the total revenue a company can expect from a customer over their relationship with the product or service.

In other words, LTV answers the fundamental question: "How valuable is a customer to our business in the long run?"

The Most Widely Accepted LTV Formula

Calculating LTV isn't rocket science; it revolves around a pretty straightforward formula:

LTV = ARPU x Gross Margin / Churn Rate​

In this equation:

• ARPU (Average Revenue Per User): It tells us how much money, on average, a customer brings in each month.

• Gross Margin: It indicates the percentage of revenue a company keeps after covering the costs of delivering the product.

• Churn Rate: It measures the percentage of customers who bid farewell to the service during a specific period.

Limitations of the Simple Formula

While the basic LTV formula is handy, it does have its quirks. It assumes that churn rates remain constant, which, in reality, rarely happens.

Additionally, it doesn't account for nuances like account expansion, which can drastically affect a customer's lifetime value.

In the real world, where customer behaviour can be unpredictable, this straightforwardness can lead to LTV predictions that miss the mark.

How Churn Affect LTV?

Churn is like LTV's arch-nemesis - churn is the main enemy that pushes LTV down on its knees.

The higher the churn rate, the lower the LTV. Customers who cancel their subscriptions or stop using the service take potential future revenue with them.

To combat churn, SaaS companies must focus on improving:

• Customer retention strategies.

• Delivering top-notch customer support.

• Consistently offering product and service value.

How Account Expansion Affect LTV?

On the flip side, account expansion is the unsung hero of LTV.

When customers expand their accounts by adding more services or upgrading their subscriptions, their LTV soars.

This reflects their satisfaction with:

• The product.

• Their eagerness to invest more in it.

SaaS businesses should actively encourage account expansion by providing the following:

• Scalable solutions.

• Showcasing the added value of premium features.

An Advanced LTV Formula by David Skok

David Skok, a luminary in the world of SaaS metrics, introduced an advanced LTV formula that takes additional variables into account:

LTV= (ARPU x Gross Margin)​ / (Churn Rate + Upsell Rate − Downsell Rate)

This formula goes beyond the basics by factoring in upsell and downsell rates.

These rates represent the percentages of customers who either upgrade their subscriptions (upsell) or downgrade them (downsell).

Skok's formula offers a more nuanced and realistic perspective on LTV dynamics by including these variables.

Conclusion

In the ever-evolving world of SaaS, grasping the concept of Customer Lifetime Value (LTV) is essential for informed decision-making.

While the traditional LTV formula is a solid starting point, it has quirks.

To harness the full potential of LTV, businesses must consider the ever-changing variables of churn and account expansion.

Moreover, embracing an advanced formula like David Skok's can provide more precise insights, enabling SaaS companies to navigate the intricate seas of customer value.

Ultimately, LTV isn't just a number; it's a guiding star that leads businesses toward sustainable growth and customer-centricity.
