What Is the Customer Success Metrics Calculator?

The Customer Success Metrics Calculator is a practical tool that measures key performance indicators related to your customers’ behavior, retention, and satisfaction. By inputting your business data, you get insights that help you understand:

• Customer churn and retention rates: How well you keep your customers over time.
• Customer acquisition cost (CAC): How much you spend to gain new customers.
• Customer lifetime value (CLV): The total revenue you can expect from a single customer.
• Net Promoter Score (NPS) and Customer Satisfaction (CSAT): Indicators of customer loyalty and happiness.
• Revenue metrics: Performance signals like monthly recurring revenue (MRR) and average revenue per user (ARPU).

Using this calculator regularly helps you track customer success trends, optimize marketing strategies, and improve your overall business performance.

Example Calculations Using the Calculator

Here’s how the calculator derives some of its key metrics based on your inputs:

1. Churn Rate

Measures the percentage of customers lost during the selected period.

$$ \text{Churn Rate} = \left(\frac{\text{Customers Lost}}{\text{Total Customers at Start}}\right) \times 100 $$

For example, if you started with 3,500 customers and lost 200:

Churn Rate = (200 / 3500) × 100 = 5.71%

2. Retention Rate

Shows the percentage of customers retained excluding new customers acquired.

$$ \text{Retention Rate} = \left(\frac{\text{Total Customers at End} – \text{New Customers}}{\text{Total Customers at Start}}\right) \times 100 $$

If you had 3,900 customers at the end and acquired 600 new ones:

Retention Rate = ((3900 – 600) / 3500) × 100 = 91.43%

3. Customer Acquisition Cost (CAC)

Average cost spent to acquire each new customer.

$$ \text{CAC} = \frac{\text{Total Sales and Marketing Expenses}}{\text{New Customers Acquired}} $$

With $65,000 marketing spend and 600 new customers:

CAC = 65,000 / 600 = $108.33

4. Customer Lifetime Value (CLV)

Estimated revenue from a customer over their lifespan.

$$ \text{CLV} = \text{Average Purchase Value} \times \text{Average Purchase Frequency} \times \text{Average Customer Lifespan} $$

Using $180 for average purchase, 3 purchases per year, and 4.2 years lifespan:

CLV = 180 × 3 × 4.2 = $2,268

5. Net Promoter Score (NPS)

Evaluates customer loyalty by subtracting detractors from promoters and expressing the result as a percentage.

$$ \text{NPS} = \left(\frac{\text{Promoters} – \text{Detractors}}{\text{Total Responses}}\right) \times 100 $$

For 500 promoters, 120 detractors, and 900 total responses:

NPS = ((500 – 120) / 900) × 100 = 42.22%

6. Customer Satisfaction Score (CSAT)

Percentage of surveyed customers who reported satisfaction.

$$ \text{CSAT} = \left(\frac{\text{Satisfied Customers}}{\text{Total Survey Responses}}\right) \times 100 $$

For 770 satisfied out of 900 responses:

CSAT = (770 / 900) × 100 = 85.56%

7. Monthly Recurring Revenue (MRR)

Average recurring revenue per subscriber in the period.

$$ \text{MRR} = \frac{\text{Total Revenue}}{\text{Number of Subscribers}} $$

With $950,000 revenue and 3,100 subscribers:

MRR = 950,000 / 3,100 = $306.45

8. Average Revenue Per User (ARPU)

Average revenue generated from each active user.

$$ \text{ARPU} = \frac{\text{Total Revenue}}{\text{Number of Active Users}} $$

Using 5,200 active users:

ARPU = 950,000 / 5,200 = $182.69

9. Expansion Revenue Rate

Percentage increase in revenue from existing customers over the start revenue.

$$ \text{Expansion Revenue Rate} = \left(\frac{\text{Additional Revenue from Existing Customers}}{\text{Total Revenue at Start}}\right) \times 100 $$

With $150,000 additional revenue and $850,000 starting revenue:

Expansion Revenue Rate = (150,000 / 850,000) × 100 = 17.65%
