Most organizations build their IT budget by taking last year’s spending and adding a percentage. That method misses the hardware that ages out, the licenses that change, and the projects nobody planned. A better approach starts from what you own, what you rent, and what the business wants to accomplish next year.
Why a copy-forward IT budget fails
Copying last year’s numbers assumes last year was normal. It rarely is. A year with few hardware failures looks cheap, and then several laptops die at once the following year.
In addition, a copy-forward plan hides decisions. Leadership approves a total but never sees the tradeoffs inside it. As a result, IT spending feels like a tax instead of an investment the business chose.
Split spending into four buckets
I recommend four categories. Each one behaves differently, so each one deserves its own line.
1. Recurring services
This bucket covers managed IT support, Microsoft 365 and other subscriptions, internet circuits, and phone systems. These costs scale with headcount, so tie them to your hiring plan. Remember that ten new employees add ten sets of licenses, support, and equipment, not just ten laptops.
2. Lifecycle replacement
Computers, servers, firewalls, switches, and wireless equipment all have useful lives. Plan replacements on a schedule instead of waiting for failures. Many organizations replace a fixed share of computers each year, so spending stays level instead of spiking.
Network equipment often gets forgotten, because it keeps working quietly until it does not.
3. Security and compliance
Insurance requirements, client contracts, and regulations drive this bucket. Keep it separate so leadership can see what protection costs and why.
Insurer requirements can also change at renewal, and the cost of meeting them often lands mid-year. Ask your broker what is changing before you finalize the numbers.
4. Projects and contingency
Office moves, new applications, and migrations belong here. Also reserve a contingency for the surprises that every year brings. Without it, every unexpected expense becomes a fight over which project to cut.
Also talk with your accountant about how each item is treated. Hardware purchases and subscriptions can land differently on your financial statements, and that affects how leadership reads the numbers.
Start with an inventory, not a template
You cannot plan replacements without knowing what you own. So pull a current list of devices with purchase dates and warranty status. Then flag anything that will pass its planned life during the coming year.
Do the same for software. List every subscription, its renewal date, its user count, and its internal owner. Many organizations find licenses still assigned to people who left months ago.
In my experience, the inventory review often pays for the time it takes, because it surfaces unused subscriptions and duplicate tools.
Put the Windows 10 cleanup in your IT budget
Microsoft ended support for Windows 10 on October 14, 2025. Computers still running it no longer get regular security updates unless the organization enrolls them in Extended Security Updates (ESU).
According to Microsoft’s ESU documentation, commercial pricing starts at $61 per device for the first year and doubles each year, for up to three years. That makes ESU a bridge, not a plan.
Keep in mind that ESU covers security fixes only. Microsoft does not add new features or general support through the program, so those machines keep aging.
Therefore, if any computers still run Windows 10, budget to replace or upgrade them. Check hardware compatibility first, because many older machines cannot run Windows 11.
Plan for price changes you do not control
Software vendors adjust pricing and licensing terms regularly. For that reason, review each major renewal and ask your vendors or IT provider about announced changes before you finalize numbers.
AI features add another wrinkle. Many platforms now sell AI capabilities as paid add-ons per user. Consider piloting them with a small group before you license the whole organization.
Multi-year agreements can lock in rates, but they also lock in license counts. Weigh the discount against how much your headcount might change.
An IT budget checklist for leadership
Before the numbers go to leadership or the board, confirm you can answer each of these questions.
- How many devices reach end of life next year, and what will replacements cost?
- Which subscriptions renew, and have you removed unused licenses?
- What do your cyber insurer and key clients require, and does the plan include those costs?
- Which projects support a stated business goal, and which are just nice to have?
- How much contingency have you set aside, and who can approve spending it?
- How does IT cost per employee change under your hiring plan?
- Which Windows 10 computers remain, and when will each one be replaced?
Where IT providers make budgeting harder
I will be direct here. Many IT providers do little to help clients plan, partly because surprise projects are profitable. A provider that knows your firewall ages out next spring should tell you now, not when it fails.
So ask your provider for a 12 to 36 month roadmap with estimated costs. If they cannot produce one, you are planning blind.
A roadmap also helps you present the plan to your board. Instead of a single total, you can show which items reduce risk, which support growth, and which you can defer if cash gets tight.
How WEBIT approaches this
Budget planning is part of our Align step. We review lifecycle dates, licensing, and security requirements with leadership, then build a roadmap that shows what is coming and roughly what it will cost.
Our strategic IT services exist to replace surprise spending with planned spending. Because we take no vendor commissions, the roadmap reflects your needs, not our margins. For migrations such as moving file servers to the cloud, our cloud infrastructure team helps size the project before it hits the plan.
Key takeaways
- Build your IT budget from an inventory and a plan, not last year’s total.
- Separate recurring services, lifecycle replacement, security, and projects.
- Budget to retire any remaining Windows 10 computers, since ESU costs rise each year.
- Ask your IT provider for a multi-year roadmap with cost estimates.
