Customer lifetime value for a local business

Customer lifetime value (CLV or LTV) is the total profit a typical customer brings your business over the whole time they stay with you. For a local business, you can estimate it with three numbers: average spend per visit, how many times a year a customer buys, and how many years they usually stay. Multiply them together, then apply your gross margin. A hair salon client who spends $80 every six weeks for four years is worth far more than one $80 haircut, and knowing that changes how much you can sensibly spend to win her.

Many local businesses never calculate it, so they judge marketing by the first sale alone and cut channels that are actually profitable. Here is a simple way to work it out and use it.

The simple formula

Customer lifetime value = average purchase value × purchases per year × years as a customer × gross margin

Example for a hair salon:

• Average visit: $80
• Visits per year: about 8
• Typical years as a client: 4
• Gross margin after products and stylist pay: 40%

Revenue over the relationship: $80 × 8 × 4 = $2,560. Lifetime value in gross profit: about $1,024.

If the salon's customer acquisition cost is $100, every new regular client returns roughly ten times what it cost to win her. That is a strong case for investing more in finding new clients, as long as they stay.

These numbers are illustrative. Use your own.

Where to find your numbers

You do not need perfect data. Reasonable estimates from your records are enough to start.

• Average purchase value: total revenue divided by number of transactions over the past year. Your POS, booking system or accounting software will give you this.
• Purchases per year: number of transactions divided by number of unique customers. If you do not track customers individually, use the bookings of 20 regular clients as a sample.
• Years as a customer: harder to measure. Look at how many customers from two or three years ago are still active. If about half are still around after two years, an average of three to four years is a reasonable estimate.
• Gross margin: what is left after direct costs such as materials, products and hourly labour.

Examples from different local businesses

These are illustrative, built to show how differently lifetime value plays out.

The table shows why the same marketing budget can be cheap for one business and expensive for another. The cleaning company can afford a much higher cost per new recurring client than the furnace company, even though its single visit is cheaper.

For one-off purchases like a kitchen renovation, lifetime value is mostly the first sale plus referrals. A satisfied renovation customer who sends two friends over the following years is worth far more than the contract alone. That is why referrals deserve their own system; my article on turning word of mouth into a referral system explains how.

How lifetime value changes your marketing decisions

Once you know CLV, three decisions get easier.

1. How much you can pay to win a customer. If lifetime gross profit is $1,000, paying $150 to acquire a customer is comfortable, even if the first visit only brings $30 in profit. Without CLV, that same $150 looks like a loss. My guide on customer acquisition cost shows how to put the two numbers side by side.

2. Which customers to target. Some customers stay longer and spend more. Look at your best long-term customers: where they live, how they found you, what they bought first. Aim your ads and messages at people like them.

3. Where to invest: new customers or existing ones. If customers leave after one or two visits, spending more on ads fills a leaky bucket. It may be smarter to fix the experience, follow up and build reminders first.

Six ways to raise customer lifetime value

1. Reminders at the right moment. An email or text when a service is due: the next cleaning, an annual furnace check, a dental cleaning. Make sure you have consent under CASL before sending commercial messages.
2. Rebook before they leave. Salons, clinics and service businesses that book the next appointment at checkout keep customers longer.
3. Subscriptions or plans. Maintenance plans, memberships or recurring cleaning turn occasional buyers into regulars.
4. Related services. A customer who trusts you for one service often buys another, if they know you offer it.
5. Fix the reasons people leave. Ask lapsed customers why they stopped coming. The answers are often fixable: scheduling, communication, a staff change.
6. Win back past customers. A short, friendly message to customers who have not returned in a year often brings some back at almost no cost. My article on winning back past customers has ideas.

Tools that make it easier

A spreadsheet works for a few dozen customers. Beyond that, a CRM or a good booking system that tracks each customer's history makes CLV visible without manual work, and lets you automate reminders. For many local businesses, a ready-made CRM set up for their process ($3,400 with me) is enough; businesses with unusual workflows sometimes need a custom CRM. Either way, the goal is the same: know who your customers are, how often they come back, and what brings them back sooner.

A note on churn

The "years as a customer" part of the formula is where small changes make a big difference. If a cleaning client stays two years instead of one, her lifetime value doubles without any change in price. That is why the quiet work of keeping customers happy, answering quickly, sending the same cleaner, fixing complaints the same day, is often the most profitable marketing a local business can do.

Start with an estimate

Do not wait for perfect data. Take the numbers you have, write down a rough lifetime value, and use it the next time you decide on a marketing budget. Refine it every six months as your records improve. Even a rough CLV leads to better decisions than judging every campaign by the first sale.
