As a SaaS founder, you know that customer churn is an inevitable reality. But how much is too much? In this article, we'll dive into the world of SaaS churn rates and explore what the data really says about app user experience.

The Mythical 5% Benchmark

When it comes to SaaS churn rates, there's a common myth that circulates: an acceptable churn rate is around 5-7% annually. But where did this number come from? And is it even realistic for your app?

Let's start by looking at the math involved. If we assume you have 1,000 customers and a 5% annual churn rate, you'd lose 50 customers over the course of a year. Not ideal, but easy to compensate for with new customer acquisition.

However, if we compare that to a 5% monthly churn figure, the same startup would lose 460 customers over the course of a year – making it necessary to replace almost half of their entire customer base each year just to "break even".

Monthly vs Annual Churn

The stark difference between annual and monthly churn stems from the fact that monthly churn compounds over time. While an annual churn rate is measured over the entire year, a 5% monthly churn reduces the customer count by an additional 5% every month.

To put this into perspective, let's use some simple math:

  • January: 1,000 * 0.95 = 950
  • February: 950 * 0.95 = 903
  • March: 903 * 0.95 = 857
  • ...
  • December: 569 * 0.95 = 540

Both annual and monthly churn show the same information (customers lost), but over different time periods.

Theory Meets Practice

To simplify things, we can use the following formulae to convert annual to monthly churn, and vice versa:

Monthly Churn Rate = 1 - (1 - Annual Churn Rate)^(1/12)

Annual Churn Rate = 1 - (1 - Monthly Churn Rate)^12

Using this formula, our "ideal" annual churn rate of 5-7% is equivalent to a monthly churn rate of just 0.4% – a loss of roughly 1 in every 200 customers.

But ask any SaaS founder about their churn rates, and chances are, they'll have a monthly churn rate far higher than 0.4%. So does that mean there's a churn epidemic sweeping through the SaaS world? Or is our "ideal" churn target simply unrealistic?

The Data Revealed

To get an idea of what's really going on in the SaaS world, let's take a look at some real-world data.

Pacific Crest Survey

In 2016, Pacific Crest surveyed 336 SaaS companies and found that:

  • Median yearly revenue was $5 million
  • Median number of full-time employees was 50
  • Median ACV (Average Contract Value) was $25,000

The median annual churn rate across the entire sample was 10%, or 0.87% per month.

Totango Metrics Report

Totango's 2016 survey targeted a broader range of businesses and found that:

  • Churn rates of less than 5% annually are not uncommon, particularly in high-growth SaaS companies
  • The majority of SaaS companies (65%) reported churn rates of 10% or less annually

Blossom Street Ventures

In an analysis of 40 publicly traded SaaS companies, Blossom Street Ventures found that:

  • Only 16 of the chosen companies reported churn figures
  • The majority seemed to report revenue churn, explaining why the median retention value was 105% (only possible as a result of negative revenue churn)

What do these findings tell us? That there's no one-size-fits-all approach to SaaS churn rates. But that doesn't mean we can't learn from the data.

Ultimately, mastering app user experience requires understanding your own churn rates and taking steps to improve them. By doing so, you'll be better equipped to build a loyal customer base and drive growth for your app.
