Annual recurring revenue per employee: What it is, why it’s important, and how to calculate it

Understanding the difference between ARR and ARR/FTE   

In order to grasp the significance of ARR/FTE, it's important to first understand each component. 

ARR is the predictable, recurring revenue generated from subscriptions or contracts over a year. For instance, if a customer signs a three-year contract worth $48,000, the ARR would be $16,000 per year. The predictability of recurring revenue allows SaaS companies to forecast, communicate, and plan better. 

Full-time equivalent (FTE), on the other hand, provides a standard unit of measurement that represents the total number of hours one full-time employee works for your company. 

To get the equivalent number of FTEs for part-time employees, you have to convert their hours based on how you define a full-time work week. 

For example, let’s say SaaS startup ABC has the following employee structure and defines “full time” as 40 hours per week:

• Three full-time developers, each working 40 hours per week
• Two part-time customer support representatives each working 30 hours per week
• One part-time content writer working 20 hours per week

To get the FTE for part-time employees, you would simply divide the hours they work each week by the number of hours in a full-time work week (40 hours per week in our example):

• Full-time developers: 3 x (40/40) = 3 FTE
• Part-time customer support: 2 x (30/40) = 1.5 FTE
• Part-time content writer: 1 x (20/40) = 0.5 FTE

Note that even though there are six people on the payroll, their workload is equivalent to five full-time employees.  

FTE is crucial for SaaS companies as it helps in managing resources, headcount planning, and evaluating team productivity across different departments or projects.

In this article, our focus is on ARR/FTE, which provides a nuanced and yet  straightforward understanding of how a SaaS company translates its most valuable resources – its people – into sustainable recurring revenue. 

The higher your ARR/FTE, the more effectively you are leveraging your human resources to drive revenue growth. 

Why is ARR/FTE important for SaaS businesses?

Any SaaS founder would agree that balancing growth and efficiency often feels like a tightrope walk. This is exactly where tracking ARR/FTE can give you a big advantage.  It offers key insights into your company's operational health and future prospects. 

SaaS CXOs use ARR/FTE to answer questions like, “Am I hiring faster than the company can generate topline results?” Or, in case of comparatively early-stage SaaS companies, leaders can gauge whether their growth trajectory has the potential to outpace costs over time (a critical factor for achieving profitability). 

ARR/FTE also supports several key business functions, such as:

• Efficiency assessment: By comparing ARR/FTE across different departments or time periods, SaaS companies can identify productivity hotspots or areas that need improvement. This granular view helps companies come up with targeted interventions to boost overall efficiency.
• Scalability evaluation: The hallmark of a successful SaaS business is growing revenue without proportionally expanding its workforce. Steadily increasing ARR/FTE is a positive indicator of scalability. 
• Strategic resource allocation: ARR/FTE can enable a data-driven approach to resource distribution by highlighting teams or departments that are more efficient in generating revenue. 
• Investor relations: A strong ARR/FTE demonstrates your ability to efficiently convert your human resources into revenue, which is a key consideration for your current and future investors.
• Competitive benchmarking: ARR/FTE allows companies to compare their performance against industry peers and competitors. With this benchmarking, you will get valuable context for setting internal targets and identifying areas for improvement.
• Decision support for tools: ARR/FTE insights guide investments in automation and AI technologies, leading to more efficient growth. 

Nuances to consider when interpreting ARR/FTE 

While ARR/FTE is a powerful indicator, it requires nuanced interpretation as its relevance can vary significantly due to various factors including company size, stage, and specific circumstances, such as a company’s country of operation.

Understanding these nuances helps leverage this metric more effectively.

1. The metric is more relevant at different stages in your business

While some recommend tracking ARR/FTE from as early as $2M ARR, its real significance often emerges around the $10M-$20M ARR mark. 

Prior to achieving the  $10M-$20M ARR mark, various factors like scale, go-to-market (GTM) strategy, and gross margins can impact your ARR/FTE ratio, making it less useful as an indicator of efficiency.

For example, early-stage startups often prioritize rapid growth over efficiency, which can lead to lower ARR/FTE ratios. This trade-off is a purely strategic choice but needs to be considered when interpreting your ARR/FTE ratio. Just as a note of caution, ARR/FTE is certainly not a meaningful exercise for pre-revenue companies or those yet to achieve product-market fit.

Scale matters

ARR/FTE tends to increase as companies grow. More “established” companies benefit from a cumulative ARR base built over time, as they reap rewards from customer retention and expansion. 

Thus, ARR/FTE should also be considered alongside bottom-line efficiency metrics to ensure a holistic view of financial health.

The market context matters, too

During uncertain economic times, investors tend to more closely scrutinize ARR/FTE, along with other revenue metrics like the Rule of 40, as these are seen as good indicators of productivity and balanced growth. 

In growth-focused markets, however, they might pay less attention to ARR/FTE in favor of pure growth metrics, such as monthly recurring revenue (MRR), customer lifetime value (LTV), and net revenue retention (NRR). 

What is a good revenue per employee ratio?

While research suggests that the overall median revenue per employee for private SaaS companies is around $112,500, this varies significantly by company size. 

For instance, companies with $1-3M ARR typically show a median of $80,000 ARR per employee, while larger companies tend to have higher ratios. 

Bootstrapped companies also have a higher ARR/FTE due to their need to be more capital efficient. For example, equity-backed companies with $1M to $3M in ARR have a median ARR per employee of $64,286. Meanwhile, bootstrapped companies of the same size show a median ARR/FTE of $104,186. 

The relative importance of benchmarks vs. ARR/FTE trends

While benchmarking is a powerful tool for planning, it’s prudent for SaaS companies to track their own ARR/FTE trends rather than constantly benchmarking with global industry peers/leaders. Your company's unique trajectory and business model should inform how you interpret and act on this metric.

This is because standard benchmarks often fail to account for factors such as geographical differences in employee costs or the use of consultants and offshore resources. 

For example, a company leveraging a region like India to capitalize on relative cost arbitrage might appear more efficient in ARR/FTE terms, but this may not reflect true operational efficiency.

If you want to benchmark your ARR/FTE results, it’s important to research and prioritize companies with similar go-to-market strategies, industries, and growth rates to benchmark your against to gain meaningful insights.
