ViralRef Customer Lifetime Value Calculator

Customer lifetime value is the total gross profit a business can expect from a single customer over the entire time that customer keeps buying from it. It helps service businesses like salons, spas, and fitness studios decide how much to invest in acquiring and retaining clients.

It multiplies your average purchase value by purchase frequency and customer lifespan to get lifetime revenue, then applies your gross margin to estimate lifetime profit. If you add a customer acquisition cost, it also calculates net CLV, the CLV to CAC ratio, and an estimated payback period.

A ratio of 3:1 or higher is generally considered healthy, meaning you earn about three dollars in lifetime value for every dollar spent acquiring a customer. A ratio below 1:1 usually means you are losing money on each new customer relationship.

Review your point-of-sale or appointment history, such as Square sales and booking reports, to see how many times an average client visits per year and how many years repeat clients typically keep coming back.

Revenue alone does not reflect profit. Gross margin accounts for the direct costs of delivering your service, such as products, labor, or supplies, so the resulting CLV reflects real profit rather than just sales volume.
