LTV Calculator - Customer Lifetime Value

Calculate Customer Lifetime Value (LTV or CLV) with our free LTV calculator. Understand the long-term value of your customers, make smarter acquisition decisions, and optimize your marketing spend.

What is Customer Lifetime Value?

Customer Lifetime Value (LTV or CLV) is the total revenue a business can expect from a single customer account throughout their relationship. It considers the average purchase amount, purchase frequency, and customer lifespan to project the total value a customer brings. LTV helps businesses determine how much they can spend on customer acquisition while remaining profitable.

Why Calculate LTV?

• Acquisition Budget: Know how much to spend acquiring customers
• Segmentation: Identify your most valuable customer segments
• Retention Focus: Understand the impact of retention efforts
• Forecasting: Predict future revenue more accurately
• Strategy Alignment: Align marketing with long-term value
• Investor Relations: Key metric for business valuation

How to Calculate LTV

Basic LTV Formula

LTV = Average Purchase Value × Purchase Frequency × Customer Lifespan

Example:
Average Purchase Value: $75
Purchase Frequency: 4 times per year
Customer Lifespan: 3 years

LTV = $75 × 4 × 3 = $900

This customer is worth $900 over their lifetime.

Detailed LTV Formula

For subscription businesses or recurring revenue models:

LTV = (ARPU × Gross Margin) ÷ Churn Rate

Where:
ARPU = Average Revenue Per User (per month or year)
Gross Margin = Percentage of revenue kept after direct costs
Churn Rate = Percentage of customers who leave each period

Example:
Monthly ARPU: $50
Gross Margin: 80%
Monthly Churn: 5%

LTV = ($50 × 0.80) ÷ 0.05
LTV = $40 ÷ 0.05
LTV = $800

Understanding the Components

1. Average Purchase Value:

• Total revenue ÷ Number of purchases
• Average transaction amount
• Can be calculated per order or per period

2. Purchase Frequency:

• Number of purchases ÷ Number of unique customers
• How often customers buy
• Expressed as times per year or month

3. Customer Lifespan:

• Average time a customer remains active
• Often expressed in years or months
• Can be calculated as 1 ÷ Churn Rate

LTV to CAC Ratio

The Golden Rule of Unit Economics

LTV:CAC Ratio compares Customer Lifetime Value to Customer Acquisition Cost.

LTV:CAC Ratio = Customer Lifetime Value ÷ Customer Acquisition Cost

Benchmark Categories:
- Excellent: 5:1 or higher
- Healthy: 3:1 to 5:1
- Acceptable: 2:1 to 3:1
- Warning: Below 2:1

Example:
LTV: $1,500
CAC: $500
Ratio: $1,500 ÷ $500 = 3:1 ✓ Healthy

Why 3:1 is the Target:

• Covers acquisition costs (1x)
• Covers operational costs (1x)
• Provides profit margin (1x)
• Allows for sustainable growth

Industry Benchmarks

Industry	Typical LTV	LTV:CAC Ratio
SaaS B2B	$1,000 - $10,000+	3:1 to 5:1
SaaS B2C	$200 - $1,000	2:1 to 4:1
E-commerce	$200 - $800	3:1 to 5:1
Subscription Box	$150 - $500	2:1 to 3:1
Retail (Fashion)	$300 - $900	3:1 to 4:1
Financial Services	$2,000 - $20,000+	4:1 to 6:1

Practice Examples

Example 1: E-commerce Store

Data:

• Annual revenue: $500,000
• Total orders: 8,000
• Unique customers: 3,000
• Average customer retention: 2.5 years

Calculation:

Average Purchase Value = $500,000 ÷ 8,000 = $62.50
Purchase Frequency = 8,000 ÷ 3,000 = 2.67 times/year

LTV = $62.50 × 2.67 × 2.5 = $417

With $150 CAC:
LTV:CAC Ratio = $417 ÷ $150 = 2.78:1 ✓ Acceptable

Example 2: SaaS Subscription

Data:

• Monthly subscription: $99
• Gross margin: 85%
• Monthly churn rate: 4%

Calculation:

ARPU = $99
Gross Margin = 0.85
Churn Rate = 0.04

LTV = ($99 × 0.85) ÷ 0.04
LTV = $84.15 ÷ 0.04
LTV = $2,104

With $600 CAC:
LTV:CAC Ratio = $2,104 ÷ $600 = 3.5:1 ✓ Healthy

Example 3: Restaurant

Data:

• Average check: $45
• Average visits per month: 1.5
• Average customer lifespan: 18 months

Calculation:

Average Purchase Value = $45
Purchase Frequency = 1.5 × 12 = 18 times/year
Customer Lifespan = 18 months = 1.5 years

LTV = $45 × 18 × 1.5 = $1,215

With $50 CAC (marketing to attract new customers):
LTV:CAC Ratio = $1,215 ÷ $50 = 24.3:1 ✓ Excellent

LTV Segmentation

Understanding Customer Value Distribution

Many businesses find that their top 20% of customers generate 80% of value (Pareto Principle).

Segment Analysis Example:

High-Value Customers (20% of base):
- LTV: $2,000+
- Frequency: Weekly purchases
- Strategy: VIP treatment, exclusive offers

Mid-Value Customers (60% of base):
- LTV: $500 - $2,000
- Frequency: Monthly purchases
- Strategy: Loyalty programs, upselling

Low-Value Customers (20% of base):
- LTV: Under $500
- Frequency: Rare purchases
- Strategy: Re-engagement or cost-efficient service
