What is SaaS Lifetime Value (LTV)?
Customer Lifetime Value (LTV) is the average net profit a customer generates for your business while using your product or service. Knowing your LTV is critical for improving customer retention, measuring profitability, and guiding your growth plans.
How Does the SaaS LTV Calculator Work?
The calculator uses advanced formulas to estimate the lifetime value of a customer based on revenue, churn, gross margin, and account expansion. Here’s how it works:
- ARPA (Average Revenue Per Account): This calculates the monthly revenue generated from a single subscription account. For example, if you have 25 customers and your Monthly Recurring Revenue (MRR) is $6,000, your ARPA is $250.
 - Gross Margin: This percentage represents the portion of revenue you retain after deducting costs. For example, if your gross margin is 65%, you keep $0.65 of every dollar earned.
 - Churn Rate: This is the percentage of customers who cancel their subscriptions each month. For example, if 1 out of 25 customers cancels, your churn rate is 4%.
 - Account Expansion: This reflects additional revenue generated per customer. For instance, an account expansion of $10/month means a customer’s monthly payment increases by $10 over time.
 - LTV Formula: Our SaaS LTV Calculator automatically combines these metrics using the following formula:
LTV = [0.5 × 1 / churn × (2 × ARPA + ARPA_growth × (1 / churn – 1))] × margin 
Example: Calculating SaaS LTV
Let’s say your SaaS product has 25 customers, and your MRR is $6,000. Using our LTV calculator:
- ARPA: MRR ($6,000) ÷ Customers (25) = $250 monthly revenue per account.
 - Gross Margin: If 35% of your revenue goes to maintenance, your gross margin is 65%.
 - Churn Rate: 1 customer cancels out of 25, making your churn rate 4%.
 - Account Expansion: You’re not adding any expansion costs, so this value is $0.
 
The calculator determines your LTV as $4,062.50, meaning each customer will, on average, generate $4,062.50 in revenue before unsubscribing.
Why is SaaS LTV Important?
Knowing your customer lifetime value is crucial for developing effective SaaS growth strategies. High LTV indicates strong customer retention and sustainable profitability. By optimizing metrics like ARPA, churn, and account expansion, you can boost your LTV and scale your business faster.
