This calculator uses the standard CLV formula: Average Purchase Value x Purchase Frequency x Customer Lifespan. It’s the simplest and most widely used CLV model, sometimes called the “historical CLV” method.
Customer Lifetime Value (CLV) is the total revenue a business can expect from a single customer account over the entire duration of their relationship.
According to Harvard Business Review, increasing customer retention rates by just 5% can increase profits by 25% to 95%. That stat explains why CLV has become the single most important metric for subscription and DTC businesses.
Example: An ecommerce store has an average order value of $65, customers order 6 times per year, and the average customer remains active for 2.5 years. CLV = $65 x 6 x 2.5 = $975. With a 35% margin, the margin-adjusted CLV is $341. If CAC is $90, the CLV:CAC ratio is 3.8:1.
| Industry | Typical CLV Range | Avg. Lifespan | Target CLV:CAC |
|---|---|---|---|
| SaaS (B2B) | $5,000 – $50,000+ | 3-7 years | 3:1 – 5:1 |
| SaaS (B2C) | $200 – $2,000 | 1-3 years | 3:1 |
| Ecommerce (DTC) | $150 – $1,500 | 1-3 years | 3:1 – 4:1 |
| Subscription Box | $300 – $900 | 6-18 months | 2.5:1 – 3:1 |
| Financial Services | $2,000 – $20,000 | 5-15 years | 4:1+ |
| Professional Services | $5,000 – $100,000+ | 2-10 years | 5:1+ |

“When we onboard a new client, the first number I ask for isn’t their traffic or revenue. It’s their CLV:CAC ratio. If it’s below 3:1, we know scaling ad spend will burn cash. If it’s above 5:1, we know they’re leaving growth on the table.”

The most actionable insight from CLV analysis isn’t the total number. It’s the difference in CLV between customer segments. Customers acquired through organic content often have 2-3x the CLV of customers from paid social because search-driven customers have already self-qualified.

There’s no universal “good” CLV. What matters is the CLV:CAC ratio. Target a minimum 3:1 ratio for sustainable growth.
Three levers: increase average order value (bundles, upsells, premium tiers), increase purchase frequency (email sequences, loyalty programs), or increase customer lifespan (better onboarding, proactive support, reducing churn triggers).
CLV and LTV are the same metric with different abbreviations. Both refer to the total revenue or profit expected from a customer over their relationship with your business.
For subscriptions, use: Monthly Recurring Revenue (MRR) per customer / Monthly Churn Rate. If your average subscription is $49/month and your monthly churn is 4%, CLV = $49 / 0.04 = $1,225.
