The short answer: there is no honest one-size number. What a small business should spend on IT depends on how many people you have, how many devices and locations you need to support and protect, and which systems your business cannot run without. For most owners, the budget comes down to one predictable monthly cost for support and security, plus software licenses, a planned schedule for replacing equipment, and any projects you already know are coming. The fastest way to get your real number is to have an IT partner review what you run and build that budget with you.
Search this question and you will see a lot of percentages. They are easy to quote, but they are based on revenue, and revenue is not what drives your IT costs.
Picture two companies with the same annual revenue. One is a 12-person engineering firm running design software. The other is a 60-person distributor with a warehouse, a second location, and an ERP system. A percentage would give them the same IT budget. Their real needs are nothing alike.
That is why a trustworthy answer starts with your business, not an average.
You do not need to become an IT expert to understand your budget. Five things account for most of it:
One current example: Windows 10 reached end of support on October 14, 2025. Businesses that kept those computers can pay Microsoft for Extended Security Updates, at $61 per device for the first year, $122 for the second, and $244 for the third. For most owners, that rising cost makes replacing the computers the better use of the money. It is exactly the kind of cost a good IT partner puts on your radar before it becomes a surprise.
Most small business IT budgets fall into five buckets:
When a business tells us its IT costs feel unpredictable, the cause is usually buckets three through five. Nobody was planning them, so they arrived as emergencies.
Most business owners do not want to track device ages and license renewals. That is our job. When Computerease works with a business, the budget comes out of the relationship instead of a spreadsheet you maintain yourself.

If you are collecting quotes from IT companies, the monthly price only tells you part of the story. Ask every provider the same questions:
A lower quote that leaves out security or onboarding just moves that cost somewhere else. Our IT Services Buyer’s Guide walks through the common pricing models and the contract clauses worth reading closely.
Sometimes the question is not “how much should we spend?” but “why does what we spend feel like it is not working?” Watch for these signs:
If any of those sound familiar, the issue is usually a lack of planning, not the size of the budget.

No single percentage fits every business. IT costs follow your people, devices, locations, and the systems you cannot run without, not your revenue. The most reliable number comes from a review of what you actually run.
Quotes differ mostly in what they include. One provider may bundle security tools, backup, onsite visits, and new-user setup, while another bills those separately. Compare the scope line by line before comparing the monthly price.
At a minimum, ask whether it covers help desk support, monitoring and patching, security tools, backup, onsite visits, and setup for new employees. Ask what is billed extra, such as projects, hardware, and after-hours work.
Yes. A good IT partner reviews your current technology, flags aging equipment and security gaps, and turns that into a predictable monthly cost plus a plan for upcoming purchases. Computerease does this for businesses across Missouri & Illinois as part of its managed IT and IT consulting services.
At least once a year, ahead of renewals, and again whenever you add staff, open a location, or take on new compliance requirements.
