Why does LTV matter for advertising?

LTV determines your maximum allowable CPA. If your LTV is $300, you can profitably spend up to $75–$100 to acquire a customer. Brands that know their LTV can outbid competitors who only optimize for first-purchase ROAS.

How do I calculate LTV for a new business?

Start with industry averages and refine as you collect data. Track your repeat purchase rate, average order value, and churn rate over 3–6 months. Even rough LTV estimates are better than ignoring it entirely.

How does LTV affect my Meta Ads strategy?

Higher LTV means you can tolerate higher CPAs and still be profitable. This lets you bid more aggressively, reach more expensive audiences, and outspend competitors who only optimize for immediate returns.

Lifetime Value (LTV)

What is LTV?

Lifetime Value (LTV) estimates the total revenue a customer will generate over their entire relationship with your business. Understanding LTV is critical for advertising because it determines how much you can afford to spend acquiring each customer. A higher LTV justifies a higher CPA.

Formula

LTV = Average Order Value × Purchase Frequency × Average Customer Lifespan

Example

If your average order is $50, customers buy 4 times per year, and stay for 3 years: LTV = $50 × 4 × 3 = $600. Knowing this, you can justify spending up to $150–$200 to acquire a customer (25–33% of LTV).

Calculate LTV by customer segment to identify which audiences generate the most long-term value.
2
Use LTV-based Lookalike audiences in Meta by uploading customer lists sorted by lifetime spend.
