SaaS Average Contract Length (ACL)

0.00 months

Sum of Contract Lengths: 0 months

Total Contracts: 0

The Average Contract Length (ACL) is calculated by dividing the sum of all contract lengths by the total number of contracts. This metric helps understand the typical duration of customer commitments.

How to Calculate SaaS Average Contract Length (ACL)

Follow these steps to calculate your SaaS average contract length(ACL):

Determine the length of each contract. This is the period for which your customer has agreed to use your services. It could be in months or years; ensure you’re consistent across all contracts. For example, one customer might have a 12-month contract, while another might have a 24-month contract.
Sum the length of all contracts. Add up the contract lengths you identified in Step 1. For example, if you have three contracts with lengths of 12, 24, and 12 months, the sum would be 48 months. This gives you the total duration of all contracts.
Count the total number of contracts. This is simply the number of individual contracts you are including in your calculation. If you added three contract lengths in the previous step, your total number of contracts is three. This includes all active contracts during the period you’re analyzing.
Divide the sum of contract lengths by the total number of contracts. This involves dividing the result from Step 2 by the result from Step 3. This will give you the average length of your contracts. Using our previous example, divide 48 months by 3 contracts, which equals an average contract length of 16 months.

SaaS Average Contract Length (ACL) = Sum of all Contract Lengths / Total Number of Contracts

What is Average Contract Length in SaaS?

The Average Contract Length (ACL) in SaaS refers to the average duration customers use a software.

This metric is determined by summing up the durations of all customer contracts. A longer ACL suggests strong customer loyalty and a stable revenue stream for the business.

Predict financial outcomes by analyzing contract durations which aid in financial planning.
Optimize pricing strategies by understanding commitment lengths to improve resource allocation.
Assess product-market fit by monitoring contract lengths, thereby guiding enhancements to ensure long-term value.

Practical Examples of SaaS Average Contract Length

Example 1: A company with 150 contracts totaling 360 months has an Average Contract Length of 2.4 months (360 months / 150 contracts). This calculation gives a quick overview of the duration of contracts. Shorter ACLs might indicate a need for longer term agreements.
Example 2: In a recent deal, a SaaS company signed up 5 new accounts: 2 yearly, 1 biennial, and 2 quarterly. Converting these to months (24, 24, 12, 6, 6) and calculating the average results in an ACL of 14.4 months. This metric helps the company determine stability and client retention trends.
Example 3: If a SaaS company has 50 contracts with some on different timelines (20 annual, 10 quarterly, 20 monthly), their total contract lengths sum up to 270 months. The Average Contract Length is then calculated as 5.4 months (270 / 50). This figure helps predict future revenue and understand client commitment levels.

Period	Total Contract Value (TCV)	Number of Contracts	Average Contract Length (ACL)	ACL Change	ACL Change (%)
Q1 2023	$500,000	50	10 months	–	–
Q2 2023	$600,000	55	10.9 months	+0.9 months	+9.0%
Q3 2023	$750,000	65	11.5 months	+0.6 months	+5.5%

This table shows a sample of a SaaS company’s Average Contract Length (ACL) over three quarters. The data includes the total contract value, the number of contracts, the calculated ACL, the period-over-period change in ACL, and the percentage change. The trend shows a positive increase in ACL, indicating that the company is succeeding in longer-term contracts.

ACL = (12 months * 100) / 100 = 12 months

Different Ways to Calculate Average Contract Length (ACL)

Simple Average Contract Length: This method calculates the average of all contract lengths within a group. It provides a general idea of the median duration of contracts.
Weighted Average Contract Length: This approach uses the contract values as weights to determine the average. It is especially useful for assessing the influence of larger contracts on the overall average.
Average Contract Length by Cohort: This calculation averages the contract lengths of customers acquired in the same period. It is beneficial for analyzing trends in contract duration over time or across different customer segments.
Average Contract Length by Tier: This method averages the lengths of contracts across different subscription tiers, helping in understanding the retention across various pricing levels.
