How Much Is a Customer Worth? Going Beyond the Cost of Doing Business
How much is a customer worth to your appliance repair business? The quick answer is the average ticket, and that is the wrong number. The average ticket is what one visit is worth. A customer is a household with a refrigerator, a washer, a dryer, a dishwasher, a range, and a microwave, and every one of them will need a repair someday.
The difference matters because the answer decides two things: how much you can afford to spend to win a customer, and how much a lost one really costs you. Get it wrong in one direction and you starve your marketing. Get it wrong in the other and you buy calls that never pay back. Here is how to work it out with your own numbers, plus a clearly labeled example so you can see the math.

Start With the Cost of Doing Business, Then Go Past It
Every price in your shop should start from what an hour actually costs you: the van, insurance, fuel, the phone, software, the tech's wage and burden, your own pay, and the hours nobody bills. Our free Cost of Doing Business calculator does that math. If you have never run it, do that first, because a customer value figure built on prices that lose money is a nice-looking number with nothing behind it.
The calculator answers what an hour costs. It does not answer "how much is a customer worth?" That is a different question, and it runs the other direction: what does a relationship bring in over the years, not what does a job cost to deliver. You need both. The first keeps you profitable on Tuesday. The second tells you what you can spend to fill next month's schedule.
Customer lifetime value is the usual name for the second number. Strip the jargon and it means the money one customer brings you from the first call until the last, counting repeat jobs, the people they send you, and anything recurring they buy. Below is the simplest way we know to build it.
How Much Is a Customer Worth? 5 Simple Ways to Find Out
You do not need an analyst. You need your field service software, a spreadsheet, and an afternoon. Work through the five steps in order and write down your own figure next to each one.
1. Start with the average ticket
Pull every completed job from the last twelve months and divide total revenue by the number of jobs. That is the average ticket: diagnostic fee, labor, and parts. Note it separately for completed repairs and for diagnostic-only visits where the customer chose to replace, because a customer who replaced on your honest advice still remembers you and may call you when the next machine fails.
Then look at the spread. A shop that does a lot of sealed-system work and a shop that mostly does dryer belts and ignitors will have very different averages, and neither is wrong. What matters is that the number is yours and not something you read in a forum.
2. Multiply by the jobs they book over the years they stay
Now group the last three years of jobs by customer. Phone number works, and so does the address, which matters more than you would think, because built-in appliances often stay with the house when the family moves. Count how many customers called more than once and how many jobs the average repeat customer booked.
Two numbers come out of this: how often a customer calls, and how long they stay. Picture a household with six major appliances. Something in that house is going to break again, and if they liked you, that call can come to you. The length of the relationship is mostly in your hands. Customers stay while the work is good and you stay in touch, and they drift away once they cannot remember your name.
3. Add the referrals they send
Ask every caller how they heard about you and log the referrer's name when the answer is a person. After a few months you can see what share of new customers came by word of mouth and roughly how many referrals a typical customer sends. The per-customer number is small and the total is not: even one referral every few years, multiplied across your whole customer list, is a lot of first tickets you never paid for.
Referrals belong in the lifetime value formula because they are revenue the customer produced, even though the check came from someone else. If nobody in your shop is asking yet, our 5-step guide to customer referrals shows how to build the ask into every job.
4. Add maintenance plans and recurring accounts
If you sell an annual dryer vent cleaning, a refrigerator coil and gasket check, or a maintenance plan with priority scheduling, add what the average customer spends on it over the years. Only some customers buy, so average it across everyone instead of counting the plan at full value.
Property managers and small commercial accounts, like a laundromat or an apartment complex's laundry room, are a different kind of customer. One account can mean many machines and repeat calls, so its lifetime value can dwarf a homeowner's. Track them separately so they do not distort your homeowner average, then notice what one good account is worth on its own.
5. Turn revenue into profit and subtract what it cost to win them
Revenue is the easy version of customer lifetime value. The useful version is gross profit: what is left after parts and the tech's pay for those jobs. Multiply lifetime revenue by your gross margin and you have it.
Then subtract what it cost to win the customer in the first place: the lead fee or ad spend, plus the office time to book them. That is your customer acquisition cost. Lifetime gross profit minus acquisition cost is the number that should drive your marketing budget, and it is the truest answer to "how much is a customer worth?"
The Example, Start to Finish
Here is the whole calculation for a made-up one-truck shop. Every figure below is an example we chose to keep the math easy. Your numbers will differ, and that is the whole point of doing your own.
| Line | Example figure |
|---|---|
| Average completed ticket | $300 |
| Jobs over six years, including the first (about one every other year) | 3 |
| Direct revenue from repairs | $900 |
| Referral revenue (one customer in three sends a new $300 job) | $100 |
| Maintenance plan revenue, averaged across all customers | $50 |
| Lifetime revenue | $1,050 |
| Gross margin after parts and tech pay | 50% |
| Lifetime gross profit | $525 |
| Cost to win the customer (leads, ads, booking time) | $120 |
| Lifetime gross profit after acquisition cost | $405 |
So, how much is a customer worth to this example shop? About $1,050 in revenue, $525 in gross profit, and $405 after the cost to win them. Not $300.
Now compare the two views. An owner who looks only at the $300 first ticket sees $150 of gross profit, watches $120 of it go to winning the customer, and decides marketing is too expensive. The same owner looking at $525 of lifetime gross profit would pay that $120 every day of the week. Same shop, same customer, different question.
It also understates the truth, because the referred customer in the fourth line has a lifetime value of their own, and so does the customer they refer. Word of mouth compounds, and lifetime value is where that shows up in the math.
What Customer Lifetime Value Tells You About Marketing Spend
Once you can answer "how much is a customer worth," the marketing budget stops being a guess. You know the most you can pay to win a customer and still make money over the relationship, so you can judge every lead source by cost per booked job instead of cost per click. A few things fall out of that right away.
- A lead source that brings customers who never call again is expensive even when the leads are cheap. Home warranty dispatches can work this way: the rate is set for you, and when something else breaks, the homeowner may call the warranty company instead of you.
- A lead source that brings homeowners who stay and refer is worth more than its cost per lead suggests. Your Google Business Profile, referrals, and past customers often sit here.
- Losing a customer costs the whole remaining lifetime value, not one ticket. A missed call from a new customer can cost you the relationship, which in the example above is up to $525 of gross profit walking to the next shop.
For the same reason, customer lifetime value is the best argument for paying a good CSR and training the techs. Every one of those dollars protects a stream of future jobs, not a single invoice. Our guide to marketing an appliance repair business without spending a fortune puts the low-cost sources in the order that protects that stream.
Where Lifetime Value Leaks Out
Customer lifetime value is not a fixed number you calculate once. It leaks out of the business every day through moments you can name, and every leak changes the answer to "how much is a customer worth?"
- The missed call. The homeowner with a dead fridge calls the next shop, and that shop gets the next six years.
- The silent parts order. A week with no update while the part is on order, and the customer decides you are disorganized.
- The price surprise. A repair quote that lands after the work starts, or a diagnostic fee that was never explained on the phone.
- The callback handled badly. One argument about a second-trip charge undoes three good visits.
- No follow-up at all. The customer was happy, and eighteen months later cannot remember your name. This one is the cheapest leak to fix.
Each of these is a customer service problem before it is a marketing problem. Our articles on customer service skills for repair teams and why it is important to monitor customer service go deeper on catching them early, before they show up as a smaller lifetime value next year.
How to Raise Customer Lifetime Value
Every input in the formula is something you can move. Here is where the leverage is, roughly in order of cost.
- Answer every call and book it. Lifetime value starts at zero if the call goes to voicemail. The free Appliance Repair CSR Course covers the call flow, presenting the fee, and speed to lead in 29 short lessons.
- Follow up on a schedule. With the customer's permission to text or email, send a thank-you the same day, a check-in at one week, a seasonal reminder twice a year, and a "we are still here" note once a year. That is how you stretch the years-they-stay number, which multiplies everything else.
- Ask for reviews and referrals the right way. Ask every customer for an honest review before you leave, make it easy, and never offer money, discounts, or gifts in exchange. Google's prohibited content policy bans incentivized reviews, and the reviews you earn honestly help new customers trust you before the first call.
- Sell a maintenance plan worth buying. Dryer vent cleaning, a refrigerator check, priority scheduling. It adds a recurring line to the formula and gives your techs a reason to be in the house once a year.
- Train the techs on the customer, not just the machine. The on-my-way text, floor protection, options instead of one price, explaining the failure in plain words. Our free 5 Star Service Calls course is built for exactly this.
- Keep the list clean. Phone, email, address, the appliances in the house, what you fixed and when. That list is the asset every step above depends on.
Service quality and marketing are not separate budgets here. Good service raises the lifetime value of every customer that marketing brings in, and marketing is what keeps that customer remembering you between repairs. A shop that does both is compounding. A shop that only buys leads is renting.
Your Past Customers Are Your Best List
Most of the ways to raise lifetime value have nothing to do with buying new leads. They are about the customers you already served: staying in touch, asking for referrals, and giving them a reason to call you first when the dishwasher starts leaking.
That is the last layer of The Organic Growth Engine, our course on everything an appliance repair company should do before spending on ads. Its five layers are getting found without paying, being trusted before they call, a website that holds up, a human who answers and books, and customers who come back and refer. The lessons on past customers, the follow-up cadence, and referrals map directly to the formula in this article.

Pair it with the Cost of Doing Business calculator and you have both questions covered: what does an hour cost, and how much is a customer worth?
Frequently Asked Questions
How much is a customer worth in appliance repair?
More than the first ticket, and the exact figure is yours to calculate. Multiply the average ticket by the number of jobs over the years a customer stays, add the referrals they send and any maintenance plan revenue, then multiply by your gross margin. In our clearly labeled example, a $300 first ticket became $525 of lifetime gross profit, or $405 after the cost to win the customer. Your own number depends on your prices, your follow-up, and your service.
How much should I spend to win a new customer?
Less than the lifetime gross profit that customer brings, with room to spare. Work out customer lifetime value first, decide what share of it you are willing to spend on acquisition, and then judge every lead source by cost per booked job against that limit. Sources that bring customers who stay and refer deserve a higher limit than sources whose customers never call again.
Do I need software to calculate customer lifetime value?
No. Your field service software or invoicing history already holds the raw data: completed jobs, dates, customers, and revenue. Export it to a spreadsheet, group the jobs by customer, and you can find the average ticket, repeat rate, and years they stay in an afternoon. Software helps later, when you want to watch the number every quarter without redoing the work.
How often should I recalculate lifetime value?
Once a year is enough for the full calculation, plus any time something big changes: a price increase, a new maintenance plan, or a new follow-up routine. Watch the inputs more often. Repeat rate, referral share, and missed calls move month to month, and they tell you whether lifetime value is rising long before the annual number does.
Ask "how much is a customer worth" once a year, with your own numbers, and every marketing and service decision after that gets easier. The customer is the relationship, not the ticket.
