Most owners can tell you what they sold yesterday. Very few can tell you what one regular customer is worth over a year — which is why so much effort goes into finding new ones and so little into keeping the ones already coming.

Annual customer value = Spend per visit × Visits per month × 12 × Gross margin
A salon regular spending 8,000 twice a month at a 70% margin: 8,000 × 2 × 12 = 192,000 of sales. 192,000 × 0.70 = 134,400 kept.
That customer is worth 134,400 a year to the business — not 8,000, which is what most owners picture when they think of them.
Most versions of this calculation ask how long a customer stays, then multiply everything by it. The trouble is that nobody knows that number. It gets guessed, the guess is usually optimistic, and it multiplies every other figure — so a small piece of wishful thinking comes out the other end as a large and confident-looking total.
A year is different. It's a period you can check against your own records — and, more importantly, you can find out next year whether you were right. A five-year figure can never be wrong in any way that costs anyone anything, which is precisely what makes it useless.
It also keeps the decision honest. If a customer is worth 134,400 a year, that's a real figure you can weigh against what you'd spend to win one. A five-year lifetime value of 672,000 is a projection about the future dressed up as a fact about the present.
The calculator will show a lifetime figure if you want it — enter roughly how long a regular stays, or answer the easier question: out of ten regulars, how many are still coming a year later? But the number it leads with is the one you can defend.
Elsewhere on this site we're insistent that net margin is the honest number — the one that counts rent, staff and your own pay. Here we use gross margin instead, and the reason is worth understanding.
One more customer doesn't add rent. Your landlord charges the same whether you serve forty people this month or forty-one. So when you're asking "what is one more customer worth?", the right answer counts only the costs that actually rise when they walk in — the goods, the materials, the products used on them.
That's gross margin, and it's the correct basis for any decision about a single additional customer: whether to spend on winning one, whether a loyalty discount is worth it, whether to chase a returning customer or a new one.
Net margin is the right basis for a different question — is the business as a whole making money? That's what the profit margin calculator is for.
Three of these the calculator measures. The fourth it can see but can't separate. The fifth it deliberately leaves alone.
For most businesses this is the cheapest growth available, because these are people who already know you, already trust you, and don't need convincing. A salon regular moving from two visits a month to three is worth as much as winning a whole new customer — without spending anything to find them.
One more year is worth exactly one more year's value. Nothing else on this list gives that much for so little, because it simply repeats everything the customer already gives you at no cost to win them again.
The smallest of the three per unit of effort, but it compounds across every visit they'll ever make, and it's often the easiest to change — they're already buying.
Which of the three wins depends on your business. For salons, shops, market stalls and restaurants, keeping customers longer usually beats everything else. For tailoring and other trades where visits are rare, getting people back more often is transformative, because doubling two visits a year matters more than anything you could do to either of them.
This is the one most owners feel and never name.
A mother orders one birthday cake. The following year she orders for the second child, then the third, then her husband's birthday, then the anniversary, then Christmas. A family finds a tailor for one outfit and comes back for school uniforms, church clothes, festive wear and eventually a wedding.
The customer hasn't changed. The number of occasions she trusts you with has.
In the arithmetic this looks like the first lever — more visits a year — so the calculator does count it. But the action behind it is completely different. You don't get there by encouraging someone to shop more often. You get there by being the person they think of when the next occasion arrives, which is built on remembering the last one: what she ordered, whose birthday it was, how she likes it done.
That's why it's worth naming separately. "Increase frequency" is a marketing instruction. "Be the one she thinks of for her daughter's birthday" is something you can actually do on Tuesday.
A salon client brings her sister. A satisfied customer recommends you to a neighbour. This looks similar to the fourth lever and is fundamentally different: the decision maker has changed.
When a mother orders a cake for her second child, that's still her decision, built on trust you've already earned. When she recommends you to her friend, the friend makes her own decision, and you have to earn that relationship independently. She may come once and never return.
That's why referred customers aren't in this calculation. Each one is a separate customer with their own value, their own frequency and their own likelihood of staying — and there is no honest way to predict how many any one customer will send you. Some people refer constantly. Most never refer at all.
We'd rather leave it out than invent a number for it. But it's a real reason why looking after the customers you have tends to beat chasing new ones: the ones you keep sometimes bring others, and the ones you never had never will.
This is the sentence worth sitting with, and it isn't a figure of speech.
Winning a customer costs you once — whatever you spent on the flyer, the airtime, the discount. Losing one costs you the whole stream of value they would have brought, and the cost of finding someone to replace them. The loss is always the bigger number, and it never appears anywhere in your accounts.
So the practical use of the annual value figure is as a ceiling. If a regular is worth 134,400 a year, spending 45,000 to win one is a sound trade. Spending nothing — which is what most small businesses do — and losing them for want of a phone call is not.
Work out what you're actually spending with the customer acquisition cost calculator, then compare the two.
Knowing what a customer is worth is half of it. The other half is how many of them you depend on — because if a handful of regulars make up most of your income, each one is worth a great deal and losing one is an emergency rather than a bad month.
