The Essential SaaS Metrics

Disclaimer: Opinions are my own. Not investment advice. Do your own research.

1. How SaaS companies are different

Instead of one-time purchases SaaS customers pay every month (or year) to access software or services via the Internet. Ideally, this business model generates a steady and growing stream of revenue, but it can also present challenges that can threaten the survival of a SaaS company.

2. Using metrics to optimize your SaaS business

It’s critical for SaaS companies to closely track key metrics as the business grows. Data on customer acquisition, lifetime value and churn rates, among other measures, will guide strategic decisions about what improvements need to be made to the business.

3. Find the financing you need

The characteristics of SaaS businesses can make it difficult for entrepreneurs to get the capital they need. Learning what lenders and other financiers are looking for in a SaaS business will improve your chances of getting financing and growing your company.

What is a SaaS company?

A software as a service company:

  • develops an application and makes it available to customers over the Internet

  • charges customers a subscription fee to use the application

  • manages and updates the software to meet user needs and security requirements

3 differences of the SaaS business model

  1. Recurring revenue

    Instead of a one-time purchase, SaaS customers pay over a period of time—a monthly or annual fee to use an application. The goal for a SaaS business is to create a growing stream of recurring revenue by attracting new customers and limiting cancellations.

  2. Scalability

    Because it’s digital and delivered over the Internet, a SaaS product can be sold to an unlimited number of users with only small increments to cost of goods sold. For SaaS businesses, key expenses are for R&D, and sales and marketing to acquire and keep customers.

  3. Comparable metrics

    SaaS businesses have similar characteristics and generate the same types of data. This makes them highly comparable, allowing entrepreneurs, lenders and investors to quickly understand a business and benchmark its performance against others.

Why SaaS companies typically lose money in the early stage

In the early stages, SaaS companies lose money because they must spend on R&D, and sales and marketing. The business then makes the money back as customers pay subscription fees over subsequent months (or years). The company generates negative cash flow until it turns the corner and becomes profitable.

The period of unprofitability typically lasts 12 to 36 months. This can be challenging for entrepreneurs and investors because money must be invested to bring on new customers with the faith that these investments will pay off down the road.

Higher growth = higher losses in the early days

The more a SaaS business spends to grow its customer base in the early days, the deeper its losses will be. However, if the business is successful in finding and retaining customers, it will eventually be rewarded with a higher rate of growth.

4 metrics to make sense of it all

Metrics allow entrepreneurs, investors and lenders to see how a company is progressing over time. For SaaS businesses, key performance metrics indicate whether a company is meeting its growth targets and where improvements are needed.

Recurring revenue

Recurring revenue is a fundamental measure of how a SaaS business is doing in terms of attracting and retaining customers in a given period—monthly (MRR), quarterly (QRR) or annually (ARR). Tracking recurring revenue allows you to understand how fast the business is growing as well as how much cash is coming in.

Breaking out different sources of new and lost revenue will help you analyze the business and make improvements.

Churn rate

The churn rate reflects the number of customers who cancel their subscription over a given period of time. It’s an important metric for understanding the stickiness of your product. As a business scales up, a high churn rate will increasingly limit its growth potential. A 10% churn rate for 500 customers is only 50 customers, but for 5,000, it’s 500 customers whose revenue must be replaced.

Revenue churn rate

An equally important metric to track is your revenue churn rate. This helps you understand how much recurring revenue (RR) your business has lost due to customer downgrades or cancellations in a given period.

Net revenue retention rate

Bringing it all together is the net revenue retention rate. It gives a comprehensive view of positive and negative changes to existing customer interactions with your company. It is the percentage of recurring revenue that’s retained from existing customers over a period of time, including revenue gained from expansion or reactivation activity offset by revenue lost through subscription downgrades and cancellations.

Negative recurring revenue churn is the holy grail of SaaS businesses. It occurs when additional revenue earned from existing customers through subscription expansion and reactivation exceeds revenue lost to customer churn. Negative revenue retention churn leads to accelerating growth for a SaaS business.

Customer acquisition cost (CAC)

CAC is the total cost of all marketing and sales activities required to find a customer and convert them into a paying subscriber. Used with another metric, the lifetime value (LTV) of a typical customer, CAC allows your SaaS business to understand whether it’s earning more from customers than it costs to acquire them. CAC is an essential metric for determining whether your SaaS business is viable and for making strategic decisions about how to improve it.

What to include in CAC

You should include every expense related to customer acquisition, including salaries, website, marketing tools, advertising, office space and other physical infrastructure for the sales and marketing teams. Once set, your method for calculating CAC should remain the same to allow for tracking performance over time.

Customer lifetime value (LTV)

LTV is the amount of profit you earn from a typical customer over the course of their relationship with you. The longer customers are loyal to your app, the greater your LTV. It is important because SaaS companies spend money to acquire customers then recoup it over the time they are subscribed to the service. Your LTV is directly related to your churn rate and will affect how much you can spend to acquire new customers.

How to increase LTV

Lifetime customer value can be increased through earning more from customers through upgrades and add-ons (account expansion for higher ARPA), reducing expenses (higher gross margin) or lowering the churn rate (customers pay you for a longer time).

2 key ratios every SaaS company should track

LTV/CAC ratio

This ratio compares the value of a new customer over its lifetime to the cost of acquiring that customer. An LTV to CAC ratio that is less than one generally indicates customer lifetime value is not compensating for the cost of acquiring new customers. Rule of thumb is that you should aim for a LTV/CAC ratio greater than three.

Months to recover customer acquisition costs

This ratio indicates how long it takes for a SaaS company to reach positive cash flow and profitability. To be successful, a company will generally need to recover customer acquisition costs within a year. While the best companies recover CAC in five to seven months, the period typically goes beyond a year for start-ups. Months to recover CAC is an indicator of the effectiveness and sustainability of a company’s strategies to attract new customers.
