Frequently asked
How is the estimate worked out?
It’s simple arithmetic on the numbers you choose — how many people stop working, what their time is worth, how long problems last and how often. Nothing is sent or stored, and it’s an estimate, not a quote.
Why does downtime cost more than it looks?
Lost working hours are just the start — there’s also missed deadlines, lost or unbacked-up data, frustrated customers and the stress of it all. The visible bill is only part of the picture.
How does a support plan help?
Managed support prevents many problems happening at all — with monitoring, maintenance, updates and verified backups — and gets you help fast when something does go wrong. See monthly IT support.

// HOW IT WORKS
How to estimate your small business IT downtime cost
This free UK calculator estimates what IT downtime costs your small business by multiplying the four numbers you choose — how many people stop working, what an hour of their time is worth, how long a typical outage lasts and how often it happens — into a rough annual cost of lost working time.
Step by step
- Count who stops — Answer step 1 — how many people can’t work when IT goes down: just one, a few (around 3), or the whole team (8+).
- Value an hour — Answer step 2 — roughly what an hour of that time is worth: under £15, £15–£30, or £30+ per hour.
- Set the outage length — Answer step 3 — how long a typical IT problem stops you: about an hour, half a day, or a full day or more.
- Set how often — Answer step 4 — how frequently it happens: a couple of times a year, every few months, or most months.
- Read your annual cost — The tool instantly shows a rough £-per-year figure for lost working time and compares it to the cost of a support plan — nothing you enter is sent or stored.
Good to know
How do you calculate the cost of IT downtime for a small business?
The simplest way is people affected × their hourly cost × hours lost per outage × outages per year, which gives the lost-labour cost. This calculator does exactly that from the four answers you pick, then rounds to a friendly annual figure — and real costs are usually higher once you add lost data, missed deadlines and stress.
What is the average cost of IT downtime per hour?
There is no single UK figure — it depends entirely on how many staff are idled and what their time is worth, which is why this tool asks for your own numbers rather than quoting a headline average. A three-person team on around £22/hour, for example, loses roughly £66 for every hour they can’t work.
Does this downtime calculator store my business figures?
No. It is simple arithmetic that runs entirely in your browser — nothing you choose is sent to us or saved anywhere, and the result is a friendly estimate to show the scale of the risk, not a quote.
