Understanding key drivers of your retention and churn rates will help you deploy company resources from product development to sales / support team staffing.
Customer Retention Rate
The % of customers you retain over a period of time, also called Gross Logo Retention.
The Customer Retention Rate from the prior period is in the next period defined as:
# of Customers at End of Period - # of New Customers Acquired During the Period / # of Customers at the Start of Period x 100
Alternatively, the number of customers retained from a period are:
# of Customers at End of Period - # Customers Lost from Period in Next Period
and the retention rate is the
# of Customers Retained / # of Customers at End of Period
Example:
Year | Beginning Customers | Customers Added | Customers Lost | End Customers |
2020 | 1546 | 1522 | 298 | 2770 |
2021 | 2770 | 2482 | 347 | 4905 |
Year | Customer Retention Rate (Method #1) | Customers Retained | Customer Retention Rate (Method #2) |
2020 | =(4905-2482)/2770=87.5% | =(2770-347)=2423 | =2423/2770=87.5% |
2021 | #NA() | =4905-#NA()= #NA() | ㅤ |
A good target for annual retention rate of existing customers is 90%.
The Customer Churn Rate is 1 - Customer Retention Rate.
Revenue Retention Rate
The Revenue Retention Rate is a metric that measures the percentage of revenue a company retains from existing customers over a specific period of time. It helps businesses understand their ability to generate ongoing revenue from their customer base.
To calculate the Revenue Retention Rate, you can use the following formula:
Revenue Retention Rate = (Revenue at End of Period - Revenue from Lost Customers) / Revenue at Start of Period x 100
Alternatively, the formula can be expressed as:
Revenue Retention Rate = (Revenue from Retained Customers) / Revenue at Start of Period x 100
Example:
Year | Revenue at Start of Period | Revenue from New Customers | Revenue from Lost Customers | Revenue at End of Period |
2020 | $100,000 | $30,000 | $10,000 | $120,000 |
2021 | $120,000 | $40,000 | $15,000 | $145,000 |
Year | Revenue Retention Rate |
2020 | ($120,000 - $10,000) / $100,000 x 100 = 110% |
2021 | ($145,000 - $15,000) / $120,000 x 100 = 100% |
A Revenue Retention Rate of 100% or higher indicates that a company is successfully retaining existing customers and generating additional revenue from them. A rate below 100% suggests that the company is losing revenue from its customer base.
Monitoring and improving the Revenue Retention Rate is essential for SaaS businesses as it directly impacts their revenue growth and profitability. High retention rates indicate customer satisfaction, loyalty, and the potential for upselling or cross-selling opportunities.
By analyzing the Revenue Retention Rate, businesses can identify areas for improvement, such as addressing customer concerns, enhancing the value proposition, or optimizing pricing and packaging strategies.
Customer Acquisition Cost
Customer Acquisition Cost (CAC) is the cost associated with acquiring a new customer. It includes all expenses related to marketing, sales, and any other activities aimed at attracting and converting new customers.
To calculate Customer Acquisition Cost, you can use the following formula:
CAC = Total Marketing and Sales Expenses / Number of New Customers Acquired
For example, if a company spends $10,000 on marketing and sales efforts in a given period and acquires 100 new customers during that time, the Customer Acquisition Cost would be:
CAC = $10,000 / 100 = $100
It's important to track and analyze the Customer Acquisition Cost to ensure that it aligns with the lifetime value of the customers. If the cost of acquiring customers exceeds their lifetime value, it may indicate an unsustainable business model.
By monitoring and optimizing the Customer Acquisition Cost, businesses can make informed decisions about their marketing and sales strategies, identify areas for cost reduction, and improve overall profitability.
Customer Life Time Value
Customer Lifetime Value (CLTV or CLV) is a measure of the total revenue a customer is expected to generate for a business throughout their entire relationship with that business. It helps businesses understand the long-term value of acquiring and retaining customers.
To calculate Customer Lifetime Value, you can use the following formula:
LTV = Average Revenue Per Customer * Customer Lifespan
The average revenue per customer is the average amount of revenue a customer generates for the business in a given period, such as a year. The customer lifespan is the average duration a customer remains engaged with the business.
For example, let's say a subscription-based SaaS company has an average revenue per customer of $100 per month, and the average customer remains subscribed for 24 months. The Customer Lifetime Value would be:
LTV = $100 * 24 = $2400
To calculate Customer Lifetime Value (LTV) from churn rate, you can use the following formula:
LTV = Revenue per Customer / Churn Rate
The revenue per customer is the average amount of revenue a customer generates for the business in a given period, such as a month or a year. The churn rate represents the percentage of customers who stop using the product or service during a specific time period.
For example, if the revenue per customer is $100 per month and the churn rate is 10%, the LTV would be:
LTV = $100 / 10% = $1000
Please note that this is a simplified calculation and does not take into account factors such as customer acquisition cost or discount rates. It provides a basic estimation of the Customer Lifetime Value based on the given revenue per customer and churn rate.
LTV/CAC Ratio
The LTV/CAC ratio is a crucial metric for SaaS businesses. It measures the relationship between the Customer Lifetime Value (LTV) and the Customer Acquisition Cost (CAC). This ratio helps determine the long-term profitability of acquiring customers.
To calculate the LTV/CAC ratio, divide the Customer Lifetime Value by the Customer Acquisition Cost:
LTV/CAC Ratio = LTV / CAC
A high LTV/CAC ratio indicates that the lifetime value of a customer exceeds the cost of acquiring that customer. This is a positive sign as it suggests that the business is generating more revenue from customers over their lifetime than it spends to acquire them.
On the other hand, a low LTV/CAC ratio indicates that the cost of acquiring customers is higher than the value they generate over their lifetime. This can be a warning sign as it may lead to unsustainable business growth.
It's important for SaaS companies to strive for a healthy LTV/CAC ratio. A ratio of 3:1 or higher is generally considered favorable, indicating a strong return on investment in customer acquisition. However, it's essential to analyze the ratio in the context of the specific industry and business model.
By monitoring and optimizing the LTV/CAC ratio, SaaS businesses can make informed decisions about marketing and sales strategies, customer retention initiatives, and overall business growth.
