What Website Downtime Actually Costs a Small Business
There’s no universal price for an hour of downtime. Here’s how to work out your own number from figures you already know — and what the sum leaves out.
There is no honest industry figure for this. What downtime costs depends on what one customer is worth to you and how many of them come through your website — and those two numbers look nothing alike for a wedding photographer, a dentist and a roofer. Anyone quoting you a universal dollars-per-minute number is selling something.
The useful news is that you can work out your own number in about five minutes, using figures you already have in your head. Then you’ll know whether an outage costs you the price of a sandwich or the price of a van, and you can decide how much to care.
The four numbers you already know
You don’t need analytics software for this. Rough is fine — you’re after the right ballpark, not two decimal places.
| The number | Where to find it |
|---|---|
| Inquiries a week that come from the website | Your call log, the form emails sitting in your inbox, or your booking notifications. Count a normal week, not your best one. |
| How many of those turn into paid work | Your own gut is good enough here. One in two, one in three, one in five. |
| What an average job is worth | A month of takings divided by the number of jobs you did that month. |
| Hours a week you’re actually open | Your real working hours. Downtime at 2am is not the same thing as downtime at 10am. |
Multiply the first three and you get what the website brings in per week. Divide that by your open hours and you get what one hour of a working website is worth. That last figure is the one worth remembering.
A worked example
Say you run a two-van plumbing company:
- The website brings in about 12 inquiries a week — calls from the number on the site, plus the contact form.
- You win roughly one in three of them.
- An average job is $400.
- You’re open six days a week, ten hours a day. Call it 60 hours.
So 12 inquiries × one in three × $400 = $1,600 a week of work arriving through the website. Spread across 60 open hours, that’s about $27 for every hour the site is up and reachable.
Now price the outages. Four hours down on a Tuesday morning is roughly $107 of inquiries at risk. A full working day is around $270. A failure late on Friday that nobody spots until Monday lunchtime — call it 40 open hours — is over $1,000.
Run the same sum with a $6,000 average job and it stops looking like small change very quickly. If you’re a cabinet maker, a dentist doing implants, or a roofer replacing whole roofs, one missed inquiry can be worth more than every website bill you pay in a year. Fewer, bigger jobs means each lost inquiry hurts more, not less.
“At risk” is not the same as “lost”
Be honest with the number in both directions, or you’ll stop trusting it.
Some of those inquiries aren’t gone. A customer who already knows you, has seen your van in their neighbour’s driveway and is only looking up your number will try again in an hour, or find you on Facebook. Existing customers are forgiving. Referrals are fairly forgiving too.
But the person comparing three companies at nine o’clock at night is not coming back. They have two other tabs open. Your dead site doesn’t read to them as “temporary technical fault” — it reads as “this company might not exist anymore”, and they click the next result without a second thought. Those are precisely the customers you spent money to attract.
So treat your hourly figure as the top of the range during business hours, and something close to zero in the middle of the night. The range is the honest version, and it’s still enough to make decisions with.
The costs the arithmetic misses
You never see the bill
Nobody rings to tell you they tried to reach you and gave up. There’s no notification, no line in your accounts, no angry email. The week just feels a bit quiet, and you put it down to the weather. That’s why owners routinely underestimate downtime — the loss is invisible by design, and the invisible losses are the ones that never get fixed.
Your Google Business Profile sends people to a dead end
For most local businesses, more people arrive through the map listing than through the search results underneath it. That listing has a website button on it. While your site is down, everyone who taps that button lands on an error message — after they had already picked you out of the list. You did the hard part and lost them on the doorstep.
Worth knowing: a customer who hits an error there doesn’t blame your hosting company. They blame you, quietly, and go back to the map.
A long outage can cost you search ranking
Search engines come back and check your pages regularly. A short blip is nothing — they’ll simply try again later, and a site that’s normally reliable gets the benefit of the doubt. An outage that runs for days is a different animal: pages can start falling out of the results, and getting them back doesn’t always happen the moment the site returns.
This is one of the few places where the length of an outage matters more than its timing. Four hours down on your busiest Saturday costs you this weekend’s customers. Four days down costs you those customers and then keeps quietly costing you for weeks after everything looks fixed.
The locked door
Not every outage looks like an outage. A site that loads perfectly but says you’re open until six when you now close at four is doing real damage — arguably worse damage, because it’s confident and wrong. Somebody drives across town, finds the lights off, and stands in your car park with their phone in their hand. That customer doesn’t just fail to buy today. They tell people, and the review they leave is about your hours page, not about your work.
Same story with an old price, a phone number you changed last year, a service you no longer offer, or a Christmas closing notice still sitting there in March. Wrong information is downtime with better manners. It costs you the customer and your credibility at the same time, and unlike a real outage, nothing anywhere flags it.
The real number is how long it takes you to find out
Here’s the part that actually sets the size of the bill. It isn’t whether your website breaks. Everything breaks eventually — cards expire, certificates lapse, updates argue with each other, hosts have bad nights. What decides the cost is the gap between the moment it breaks and the moment you know.
Take one identical fault: a security certificate that quietly expires at midnight. Spotted and fixed by half past midnight, it costs you nothing at all. Spotted on Thursday because a customer happens to mention it, it costs you most of a week’s inquiries. Same fault, same fix, same five minutes of work at the end. The entire difference in price is in the noticing.
And most owners have no way of noticing. You’re on a job, under a sink, in someone’s mouth, up a ladder — not refreshing your own homepage. Plenty of small business sites are down right now and won’t be found out until somebody says something at a till.
What actually shrinks the number
Two things do most of the work, and neither is complicated:
- Have something watching the site all the time, so the clock starts in minutes instead of days. This is the single biggest lever, and it’s also the cheapest one.
- Be able to put things back. Most breakages arrive on the back of a change, so if every change is saved before it goes live and can be undone in one click, a frightening outage turns into a two-minute inconvenience.
After that it’s housekeeping, which prevents the common causes rather than shortening them: auto-renew switched on for the domain name and the hosting, renewal emails going to an address you genuinely read, a backup somebody has actually tested restoring, and one person whose job it is to keep the hours, prices and phone number on the site matching reality.
None of that is expensive. It’s just work that nobody owns — which is exactly why it’s usually the thing that costs you.
Common questions
- How much does an hour of website downtime cost a small business?
- There’s no single figure, and any number quoted as an industry average is almost certainly meaningless for your trade. Work it out from your own weekly inquiries, how many of them you win, and your average job value. For most small businesses the answer lands somewhere between “barely noticeable” and “a job a day”, and the only way to know which is to do the sum.
- My website barely gets any traffic. Does downtime really matter?
- Usually more than you’d expect. Low-traffic local sites tend to get visitors who are already close to buying — someone who types your business name in has heard about you and is looking for a reason to call. Ten visitors who are ready to book are worth far more than a thousand who are browsing.
- Will my hosting company compensate me for lost business?
- Almost never. Most hosting guarantees pay out a credit against your hosting fee, which might be a couple of dollars, and they usually require you to notice and claim within a set window. That covers the rent on the server, not the jobs you didn’t get. Treat it as a rounding error rather than protection.
- Does a short outage damage my search ranking?
- A brief outage rarely does lasting harm — search engines retry, and a normally reliable site is given some latitude. The risk grows with length: an outage running for days can push pages out of results, and recovery isn’t always instant. In practice the customers you lose during business hours will cost you more than the ranking will.
- How do I find out my site is down without checking it all day?
- You need something checking it for you and telling you when it fails, because refreshing your own homepage between jobs isn’t a plan. The important part is the alert, not the checking — a monitor that spots an outage and doesn’t reach you is no better than nobody watching. Make sure the alert goes somewhere you’ll see it within minutes, not to an inbox you open on Fridays.
