IT Budget Percentage of Revenue: A Texas Guide

Revenue-based budgeting works because it scales with you. A company doing $5 million a year has different risk exposure and different tooling needs than one doing $50 million, but both need a defensible number that a CFO can explain in a board meeting. Tying IT spend to revenue also keeps you from the two most common failure modes: starving IT during a good year because cash is tight, or overspending on tools nobody uses because a vendor had a good sales pitch.

The range you'll hear from analysts and peer groups varies by industry, company size, and how much of the business is already digital. Rather than chase a single magic percentage, build your number from the categories that actually drive cost, then check it against what similar companies in your industry report spending. That's the difference between an informed budget and a guess dressed up as one.

A useful IT budget has distinct buckets, each with its own logic:

• Run-the-business managed services — help desk, patching, backups, monitoring. This is the baseline cost of keeping lights on, usually delivered through managed IT services.
• Security — endpoint detection, email filtering, SIEM, and the access controls covered under cybersecurity and privileged access management. This bucket grows fastest as breach costs and compliance pressure rise.
• Cloud and productivity — Microsoft 365, cloud infrastructure, and the licensing sprawl that comes with both. Managed Microsoft 365 and cloud services fall here.
• Network and connectivity — switches, firewalls, wireless, and the physical plumbing covered under network technology.
• Hardware refresh and capital projects — the lumpy stuff: a new office buildout, a server refresh, a line-of-business software migration.

Once you separate these, you'll notice something: the "run-the-business" bucket should be fairly stable as a percentage of revenue year over year. The project bucket is what makes total spend look erratic on a spreadsheet, and it's why comparing this year's total dollar figure to last year's is a bad way to judge whether you're spending correctly.

Texas businesses have a few state-specific variables that change the math. Texas SB 2610, effective September 1, 2025, shields businesses with 20 to 99 employees from exemplary damages in a breach lawsuit if they've implemented the CIS Controls IG1 safeguard set — 56 specific controls. It doesn't create a new lawsuit risk and it doesn't guarantee you avoid a suit entirely, but it changes the calculus on how much you should be spending on foundational security controls versus hoping nothing happens (Texas SB 2610, as of 2026-08-20). If you're in that employee band and haven't mapped your controls to IG1, that's a budget conversation worth having before your insurance renewal, not after an incident.

If you handle health data, HIPAA compliance adds a layer of required documentation, access controls, and audit logging that isn't optional and isn't cheap to bolt on after the fact. If you're a financial services company, mortgage broker, or anyone touching consumer financial data, the FTC Safeguards Rule does the same thing. Both should be line items in your security bucket, not surprises.

Here's the process we walk clients through, roughly in order:

• Pull last three years of actual IT spend, categorized into the buckets above. Most companies have never done this and are surprised by what they find.
• Separate recurring spend from one-time capital projects. Calculate recurring spend as a percentage of trailing twelve-month revenue.
• Compare that percentage against industry peer benchmarks — your trade association, your insurance broker, or a peer CFO group usually has this data.
• Identify gaps: are you underspending on security relative to your compliance obligations? Overspending on licenses nobody uses?
• Build next year's number as a percentage of projected revenue, then layer in known capital projects separately so they don't distort the baseline.
• Revisit quarterly. Revenue moves, and so should the dollar figure tied to your percentage.

This isn't a one-afternoon exercise the first time you do it. But once the categories are set up, updating the model each year takes an hour, not a week.

Underinvesting in security doesn't save money — it defers cost and adds a multiplier. The median cost to recover from a ransomware incident, excluding any ransom paid, runs $375,000, with the mean pulled much higher by a long tail of catastrophic cases near $1.7 million (Sophos, State of Ransomware 2026, as of 2026-08-20). That's recovery cost alone — IT labor, downtime, forensics, notification. Most victims, 69% according to the same report, don't even pay the ransom, so that recovery figure isn't the cost of paying criminals; it's the cost of cleaning up afterward.

A lot of that exposure traces back to basic access hygiene. Credential abuse shows up at some point in 39% of breaches, making it the single most common thread across incidents (Verizon 2026 DBIR, as of 2026-08-20). And once a known vulnerability is flagged by a scanner, the median time organizations take to actually fix it has stretched to 43 days, up from 32 the year before (Verizon 2026 DBIR, Fig. 13, as of 2026-08-20). Neither of those numbers requires exotic attackers. They require a company that budgeted for IT as an afterthought instead of a category with real numbers behind it.

Sometimes the budgeting exercise reveals that your current provider's pricing doesn't map to any of these categories cleanly, or that you're paying for services you can't account for. If that's where you land, our guide to switching IT providers walks through how to make that transition without a coverage gap. Companies in Houston, Sugar Land, Katy, and around the Woodlands area go through this more often than you'd think, usually after a growth spurt outpaces what a part-time IT person or a single-tech shop can support.

Is there one correct percentage of revenue every business should spend on IT?

No, and be skeptical of anyone who gives you a single number without asking about your industry, compliance obligations, and how digital your operations are. Use peer benchmarks and your own three-year spend history as your starting point, then adjust for the compliance and risk factors specific to your business.

Should security spending be a separate line item from general IT?

Yes. Lumping security into general IT spend makes it too easy to cut in a tight year, and it hides whether you're actually meeting obligations like HIPAA or the FTC Safeguards Rule. Track it separately and defend it separately.

How often should we revisit the budget once it's set?

Quarterly, at minimum tied to revenue changes. A percentage-of-revenue model only works if you actually update the revenue side; otherwise you're back to guessing with extra steps.

Does SB 2610 mean we're safe from lawsuits if we hit IG1?

No. It removes exposure to exemplary damages for qualifying businesses that implement the CIS Controls IG1 safeguard set — it doesn't bar lawsuits and it doesn't create a new legal claim. It's a reason to prioritize foundational controls, not a substitute for a real security program.
