How to Use This LTV Calculator

Follow these simple steps to calculate customer lifetime value in seconds:

1. Enter your Average Order Value (AOV) – how much a customer spends per transaction

2. Enter your Purchase Frequency – how many times a customer buys per year

3. Enter your Customer Lifespan – how many years a customer stays active

4. (Optional) Enter your Gross Margin % for net profit LTV

5. Click “Calculate LTV”

6. See your customer lifetime value instantly

Example: If your average order value is $50,customersbuy4time\; speryear,andstay\; for3years,yourLTV\; is$600 – meaning each customer is worth $600 in total revenue over their lifetime.

LTV Formula & Calculation Example

Understanding the formula helps you forecast revenue and set acquisition budgets.

Standard LTV Formula (Revenue-Based):

LTV ($) = Average Order Value (AOV) × Purchase Frequency × Customer Lifespan

Net LTV Formula (Profit-Based):

Net LTV = (AOV × Gross Margin %) × Purchase Frequency × Customer Lifespan

Real-Life Example Table:

A higher LTV means more value from each customer – you can afford to spend more to acquire them.

What Is a Good LTV? 

A “good” LTV varies dramatically by industry, business model, and pricing. Use these benchmarks:

Important: Always compare LTV to CAC. LTV alone doesn’t tell you profitability.

LTV to CAC Ratio: The Most Important Metric

The relationship between LTV and CAC determines your business health and ability to scale.

The Golden Rule: LTV should be at least 3x CAC

Example Calculation:

• LTV = $600

• CAC = $150

• LTV:CAC Ratio = 4:1 → Very Healthy

Example Problem:

• LTV = $300

• CAC = $200

• LTV:CAC Ratio = 1.5:1 → At risk – improve LTV or lower CAC

Maximum Recommended CAC Formula:

Max CAC = LTV ÷ 3

Example: If LTV = 900,don′tspendmorethan900,don′tspendmorethan300 to acquire a customer.

7. Reduce Churn (Especially for Subscriptions)

• Understand why customers leave (exit surveys)

• Win-back campaigns for canceled users

• Flexible plans (pause, downgrade)

• Result: 20% – 50% higher LTV

LTV for Different Business Models

How you calculate LTV depends on your business model:

E-commerce / DTC

LTV = AOV × Annual Purchase Frequency × Average Customer Lifespan (years)

Example: AOV $60\times 3purchases/year\times 2years=$360 LTV

SaaS (Subscription)

LTV = Average Monthly Revenue Per Customer (ARPU) × Gross Margin % × (1 ÷ Monthly Churn Rate)

Example: ARPU $50, Gross Margin 80%, Monthly Churn 3% (0.03)

LTV = $50 × 0.80 × (1 ÷ 0.03) = $50 × 0.80 × 33.33 = $1,333

Simplified SaaS LTV Formula (Revenue):

LTV = Average Monthly Revenue Per Customer ÷ Monthly Churn Rate

Mobile Apps (Freemium)

LTV (Paying User) = Average Revenue Per Paying User (ARPPU) × Customer Lifespan

Note: Free users have low LTV (ad revenue only)

Marketplace (e.g., Airbnb, Uber)

LTV = Average Commission per Transaction × Transactions per Year × Customer Lifespan

LTV by Cohort: Advanced Analysis

Your overall LTV is an average. But different customer groups (cohorts) have different LTVs.

Common Cohorts to Track:

Example LTV by Channel:

Insight: Referral customers are your most valuable – invest more in referral programs.

LTV vs. Other Metrics

Key takeaway: LTV is your north star metric for sustainable growth. Everything else feeds into it.

How to Predict LTV for New Businesses

No historical data yet? Use these methods to estimate LTV:

Method 1: Analogous Businesses

• Find a similar business in your industry

• Use their published LTV as a benchmark

• Adjust for your pricing and margins

Method 2: Unit Economics Estimation

• Estimate AOV (your pricing)

• Estimate frequency (how often would YOU buy?)

• Estimate lifespan (optimistic, realistic, pessimistic)

Method 3: Early Customer Data

• After 30-90 days of sales

• Track repeat purchase rate for early customers

• Extrapolate based on industry averages

Method 4: Investor Benchmarks

• VCs often expect LTV:CAC of 3:1 or higher

• Work backward: If CAC is $100,LTVshouldbe$300+

• Adjust based on your business stage

LTV by Retention Rate Table

For subscription businesses, retention directly drives LTV:

Formula Used: Lifespan = 1 ÷ Monthly Churn Rate

Key insight: Reducing churn from 5% to 3% increases LTV by 66% ($800\to$1,333)

Frequently Asked Questions

Q1: What is a good customer lifetime value?

A: There’s no universal number. A good LTV is one that’s at least 3x your CAC. For example, if your CAC is $100,agoodLTVis$300 or higher.

Q2: What’s the difference between LTV and CLV?

A: Nothing. CLV (Customer Lifetime Value) and LTV are the same metric. Some marketers use CLV, others use LTV.

Q3: How do I calculate LTV without customer lifespan data?

A: Use retention rate instead. For subscription: LTV = ARPU ÷ Monthly Churn Rate. For e-commerce: LTV = AOV × (1 + Repeat Purchase Rate) ÷ (1 – Repeat Purchase Rate)

Q4: How often should I calculate LTV?

A: Monthly for most businesses. Quarterly for longer sales cycles. Track trends over time – is LTV increasing or decreasing?

Q5: What is a good LTV:CAC ratio for a startup?

A: Early-stage startups can survive with 2:1 or 2.5:1. Aim for 3:1 within 12-18 months. Above 5:1 means you’re likely under-investing in growth.

Q6: Why is my LTV decreasing over time?

A: Possible reasons:

• Customer retention is dropping (higher churn)

• Average order value is declining

• Purchase frequency is decreasing

• You’re acquiring lower-quality customers (broader targeting)

Q7: Should I include refunds or cancellations in LTV?

A: Yes. Use net revenue after refunds and cancellations. Gross LTV is misleading.

Q8: How do I calculate LTV for a one-time purchase product?

A: LTV = AOV × (1 + Referral Value). Or simply: LTV = AOV if customers rarely buy again. Focus on increasing frequency.

Q9: What’s predictive LTV?

A: Predictive LTV uses machine learning to forecast future customer value based on early behaviors (e.g., first 30 days). Advanced – not needed for most small businesses.

Q10: How does LTV affect fundraising?

A: Investors love high LTV:CAC ratios. A 3:1+ ratio shows healthy unit economics. A 1:1 ratio shows you can’t scale profitably.
