What Does IT Actually Cost a Small Business Per Year?
Ask ten small business owners what they spend on IT per year and nine of them will guess. The tenth keeps a spreadsheet and wins every argument at renewal time. IT is not one bill. It is four bills wearing disguises, and if you only look at one of them, every conversation about the other three goes sideways.
Here is the number most owners are actually living with, the four buckets it hides in, and the simple math for a ten-person shop.
The headline numbers
The benchmarks cluster in a narrow band. The small-business guidance quoted most often says a small business should expect to spend 4 to 7 percent of revenue on IT, which works out to roughly $1,800 to $4,000 per employee per year, per ITBudgetCalculator's SMB benchmark. That figure is everything: the people, the software, and the hardware.
A ten-person company at the midpoint of that band is spending $25,000 to $40,000 a year before anything goes wrong. If your gut says that sounds high, you are probably only counting one bucket.
Bucket one: the person who answers when it breaks
This is usually your biggest single line, and it is the one most worth paying for. Managed IT pricing for small companies runs $100 to $149 per user per month, per Integris's 2025 pricing guide, climbing to $150 to $250 per person per month once real security services are included, per IronEdge's small-business guide. Ten people at $125 each is $15,000 a year.
That number buys you the thing you actually need: someone who answers the phone, watches the backups, and patches the firewall before you learn what a firewall was. If your "IT guy" is your nephew's friend who shows up when something is on fire, skip this bucket and you are paying the deductible later.
Bucket two: software, the line you stopped noticing
Across all company sizes, average software spend hit $4,830 per employee per year in 2025, up from $3,960 the year before, per Zylo's numbers reported by Mekari. A small business runs leaner than the average, but the direction is the same, and the mechanism is the zombie subscription: the project tool from 2022, the design seat for someone who quit, the two invoicing apps because nobody cancelled the old one.
This bucket is the one you can cut without pain. Inventory every subscription, kill the zombies, and you will usually find a month of managed IT sitting there doing nothing.
Bucket three: hardware, including the server in the closet
A business laptop costs $1,000 to $1,500 and lasts three to four years, so budget roughly $350 per person per year in amortized replacements. The expensive hardware question is the server in the closet: $3,000 to $8,000 to buy, plus the weekend it dies.
Most ten-person shops do not need the closet server anymore. The cloud services you are already paying for in bucket two replaced it, and nobody told the closet.
Bucket four: projects and surprises
The website rebuild. The email migration. The morning the backups turn out to be imaginary. Budget 10 to 15 percent of the other three buckets as contingency, and stop treating surprise IT spending as bad luck. It is the most predictable line in the budget.
The ten-person math, worked
Managed IT at $125 per person: $15,000. Software at a realistic SMB figure after an audit: $12,000. Hardware amortized: $4,000. Contingency at 12 percent: $3,700. Total: about $35,000 a year, or $3,500 per employee, which lands squarely inside the $1,800-to-$4,000 band.
Now you know what the conversation is actually about the next time a vendor quotes you something: which bucket the money is in, and whether that bucket is doing anything for you.
