IT Budget Planning Guide for Small Business

How much should you spend on IT? This guide gives you real numbers, industry benchmarks, and a framework to build a 3-year technology budget that actually makes sense.

📊 Industry Benchmarks: What Should You Spend?

Industry research consistently shows that businesses should allocate 3-7% of revenue to IT, depending on industry and growth stage. Here's the breakdown:

Industry	% of Revenue	Why
Financial Services	6–10%	Heavy compliance, security, and data requirements
Healthcare	4–7%	HIPAA compliance, EHR systems, telehealth
Professional Services	3–6%	Cloud collaboration, time tracking, document management
Retail / Hospitality	2–4%	POS systems, inventory, WiFi, security cameras
Construction / Trades	2–4%	Project management, mobile devices, fleet tracking
Manufacturing	2–4%	ERP, OT security, floor automation
Small Business Average	4–6%	General benchmark for companies under 100 employees

Reality check: Most small businesses we audit are spending 1-2% of revenue on IT — and it shows. Aging hardware, no backups, no security. They're not saving money; they're accumulating risk and technical debt.

💸 The Hidden Costs You're Not Tracking

⏱️ Downtime

The average SMB loses $8,000–$25,000 per hour of downtime. Even a half-day outage from a dead server or ransomware attack can cost more than a year of proactive IT.

👻 Shadow IT

Employees signing up for unauthorized apps (Dropbox, free CRMs, personal email). Each one is an unmanaged security risk and a potential data leak you don't know about.

🏚️ Technical Debt

That Windows 10 PC from 2017 still "works" — until it doesn't. Deferred upgrades compound: a $1,200 replacement today becomes a $5,000 emergency migration tomorrow.

🧑‍💼 Productivity Loss

Employees spend an average of 22 minutes per day dealing with slow computers, printer issues, and IT workarounds. That's 90+ hours/year per person.

Quick Downtime Cost Formula:
(Number of employees affected) × (average hourly cost per employee) × (hours of downtime) = Cost

Example: 15 employees × $45/hr × 8 hours = $5,400 in a single day

📈 ROI: How IT Investment Pays Back

Example 1: Managed IT vs. Break/Fix

	Break/Fix (Reactive)	Managed IT (Proactive)
Monthly cost (20 users)	$0–$800 (unpredictable)	$2,000–$3,000 (fixed)
Annual emergency incidents	4–8 (avg $2,500 each)	0–2 (most prevented)
Major outage per year	1–2 (avg $10,000)	Rare (monitoring catches early)
Actual annual cost	$20,000–$35,000	$24,000–$36,000
Difference	Similar cost, but managed IT includes: monitoring, patching, backups, security, help desk, planning. Break/fix includes: nothing until something breaks.

Example 2: Cloud Migration ROI

Item	On-Premise (5-year TCO)	Cloud (5-year TCO)
Server hardware	$12,000–$25,000	$0
Licensing	$8,000–$15,000	Included in subscription
Maintenance / management	$15,000–$30,000	$5,000–$10,000
Cloud subscription (5 yr)	$0	$18,000–$36,000
Power / cooling	$3,000–$6,000	$0
5-Year Total	$38,000–$76,000	$23,000–$46,000

🤔 Build vs. Buy Decision Framework

Should you hire internal IT staff or partner with a Managed Service Provider (MSP)?

Factor	In-House IT	MSP / Outsourced
Cost (1-person IT dept)	$65K–$95K salary + benefits + tools = $100K–$140K/yr	$24K–$96K/yr depending on scope
Coverage hours	Business hours (1 person can't be 24/7)	24/7 monitoring + after-hours support
Expertise depth	One person knows some things well	Team with diverse specializations
Vacation / sick time	No coverage when they're out	Team-based — always covered
Best for	50+ employees, specialized needs, internal projects	Under 50 employees, standard IT needs

The sweet spot for most 20–80 person companies: Co-managed IT — a part-time or full-time internal IT person focused on business-specific needs, partnered with an MSP for security, monitoring, help desk, and infrastructure management.

⚠️ Don't skip Year 1. We see businesses that try to spread critical security investments over 3 years to "save money." Meanwhile, ransomware doesn't wait for your budget cycle. Get MFA, backups, and endpoint security in place immediately — everything else can be phased.
