Customer Lifetime Value (CLV) is a critical metric for driving long-term business success. It measures the total revenue a customer generates over their entire relationship with your brand, guiding smarter decisions to boost retention, cut acquisition costs, and maximise profitability.

In this blog, you’ll learn:

• What CLV is and why it matters.

• Step-by-step formulas to calculate CLV.

• Actionable, specific strategies to maximise CLV using tools like Klaviyo.

Understanding Customer Lifetime Value in Marketing

What is Customer Lifetime Value (CLV)?

Customer Lifetime Value (CLV) measures the total revenue a business can expect from a customer throughout their relationship. It’s a key metric for assessing long-term profitability and identifying high-value customers to prioritise marketing efforts.

Why is CLV Crucial for Marketers?

• Drives ROI: CLV focuses on retaining high-value customers, and maximising ROI by deepening existing relationships instead of acquiring new ones.

• Informs Strategy: Marketers can allocate resources effectively by identifying and targeting high-CLV customers with tailored offers and campaigns.

• Boosts Retention: A higher CLV ensures long-term growth by encouraging repeat purchases through loyalty programs and personalised engagement.

CLV vs. Customer Acquisition Cost (CAC)

Retaining customers is 5-7 times cheaper than acquiring new ones, making it a cost-effective approach to profitability. High CLV combined with low CAC creates a strong foundation for sustainable growth.

How to Calculate Customer Lifetime Value in Marketing

Formula to Calculate CLV

Customer Lifetime Value (CLV) can be calculated using a simple formula:

For example:

• Average Order Value: $50

• Purchase Frequency: 5 times/year

• Customer Lifespan: 3 years

CLV = $50 × 5 × 3 = $750

This means that, on average, a single customer contributes $750 in revenue over their lifetime.

Actionable Strategies to Boost Customer Lifetime Value

1. Use Predictive Analytics for Replenishment Flows

• You can also use Klaviyo’s “Expected Date of Next Order” to time SMS nudges or email reminders 3–5 days before a customer is due to reorder.

  Pro Tip: Use dynamic splits in your flows based on expected purchase timing for more personalised automation.

Retention vs. Acquisition – Where Should You Focus?

Retention Yields Higher ROI

Focusing on retention delivers significant profitability, with just a 5% increase boosting profits by 25-95%. Retained customers offer higher Customer Lifetime Value (CLV), lower acquisition costs, and more sustainable revenue through repeat purchases and referrals.

Strategies to Balance Retention and Acquisition

Retention:

• Loyalty programs: Platforms like Smile.io and LoyaltyLion reward repeat purchases and customer advocacy.

• Dynamic email flows with Klaviyo: Automate post-purchase and win-back campaigns to build strong customer relationships.

• Personalised experiences: Use Klaviyo’s segmentation tools to tailor offers based on purchase history or preferences.

Acquisition:

• Referral programs: Encourage customers to bring in new buyers with incentives like discounts or points.

• TikTok and Klaviyo integration: Combine TikTok’s reach with Klaviyo’s automation to attract and nurture new audiences effectively.

Pro Tip: Explore how TikTok and Klaviyo can supercharge your Return on Ad Spend (ROAS) with acquisition and retention synergy.
