Technical Debt Explained for Non-Technical Executives: What It Costs and When to Pay It Down

A 90-person company wants to add a new customer portal. The IT provider says the project will take twice as long as quoted, because the file server is nine years old, two systems share one admin password, and a billing tool only works with an operating system the vendor stopped updating. Nobody made a bad decision. Each shortcut made sense the year it was taken.

That pile of old shortcuts is technical debt. It is one of the most common reasons a growing company's technology projects run late, run over budget, or quietly turn into a security problem.

What technical debt actually is

Technical debt is the future cost of past shortcuts in your technology. The name comes from finance for a reason. You borrowed time or money by choosing the fast option, and you now pay interest on it until you pay it back.

For a company with 25 to 200 employees, it rarely means messy software code. It usually looks like this:

• Computers, servers or network equipment that are past their useful life
• Software the vendor no longer updates or supports
• Systems that only one person understands, with no documentation
• Shared logins and accounts nobody has reviewed in years
• Tools that overlap, or that were bought for a need that no longer exists
• Manual workarounds that exist because two systems never got connected

None of these is a crisis on its own. Together they make everything else slower, more expensive and riskier.

What it costs

The most cited research on this comes from McKinsey, which surveyed 50 chief information officers at financial services and technology companies with more than $1 billion in revenue. Those CIOs estimated that tech debt equals 20 to 40 percent of the value of their total technology estate. They also reported that 10 to 20 percent of the technology budget meant for new products goes to resolving tech debt instead.

Two cautions apply. The respondents were far larger than your company, and the figures are CIO estimates, not audited numbers. Treat them as a direction, not a prediction for your business.

The arithmetic is still useful. If your company plans $500,000 of technology projects this year and your debt behaves like the low end of that range, about $50,000 never reaches the project. At the high end, it is $100,000. That money does not show up as a line item called "technical debt." It shows up as a project that took longer than quoted.

Debt costs you in four ways:

1. Slower projects. Every new system has to work around the old one.
2. Higher support cost. Old equipment fails more often, and fixing it takes more of your IT provider's time.
3. Security exposure. Unsupported software stops getting security fixes. Microsoft ended support for Windows 10 on October 14, 2025, which means any company still running it on work computers is running machines that no longer receive security updates.
4. Key-person risk. When one employee or one vendor holds all the knowledge, their departure becomes a business event.

The part that matters to a CEO, COO or CFO: security

Of the four, security is the one that turns a slow-project problem into a business problem. Attackers do not need a clever method when a company runs software with known, unfixed weaknesses. Old systems also tend to be the ones that cannot support modern protections such as multi-factor sign-in or current backup tools.

Cyber insurers and larger clients notice this too. A renewal questionnaire or a client security review asks which systems are unsupported, and "we have always run it that way" is not an answer either of them accepts. A company that cannot show a list of its unsupported systems, and a plan for each, often finds the gap during a renewal or a sales cycle, which is the worst time to find it.

Not all debt is worth paying down

Some debt is fine. A ten-year-old printer that works and touches nothing sensitive is not a priority. Paying down everything at once is neither affordable nor necessary. The goal is to rank it.

Score each item on two questions:

• Risk: If this fails or gets attacked, how bad is the damage? Consider customer data, money movement, and how many people stop working.
• Drag: How much does it slow down or add cost to everything around it?

An item that is high on both goes first. An item that is low on both can wait or be retired.

A five-step framework for deciding

1. List it. Ask your IT provider or internal IT lead for a plain inventory: every server, major application, and device type, with its age, its vendor support status, and who maintains it. If this list does not exist, creating it is the first win.
2. Flag what is unsupported. Mark anything the vendor no longer updates. These carry the sharpest security risk and belong at the top.
3. Score risk and drag. Use a simple high, medium, low rating for each. A 30-minute meeting is enough for a first pass.
4. Attach a cost and a date. For each high item, get a replacement or fix cost from your provider and a target quarter. A debt item with no date is a wish.
5. Fund a fixed slice every year. Set aside a set share of the technology budget for paydown, and review it quarterly. Many companies find a steady slice works better than one large cleanup that never gets approved.

When to pay it down

Pay down now when any of these is true:

• The item is unsupported and touches customer, employee or financial data
• Your cyber insurance renewal or a client's security review is within the next two quarters
• A planned project, acquisition or move depends on the item
• The item has a single point of failure, such as one person or one machine

Wait when the item is stable, supported, isolated from sensitive data, and not blocking anything on the next year's plan. Write down the decision and the date you will revisit it. A documented decision to wait is a very different thing from not knowing the item exists.

How security work fits in

Security gaps are the most urgent kind of technical debt, and they are the ones a growing company is least likely to track. Elevaire Managed Security works alongside your existing IT provider or internal team to find and close these gaps: unsupported systems, unreviewed accounts, missing protections and weak backups. A security baseline gives you a clear starting list to measure against.

The decisions about what to fund and when are leadership decisions. A virtual CISO can own the risk ranking, put the choices in writing, and present them to your leadership team or board in plain terms, so security debt gets weighed against everything else the company wants to spend on. Example engagement: a 70-person company has twelve laptops still on an unsupported operating system and a file server past its warranty. Elevaire would rank both against the company's insurance renewal date, recommend which to replace first, and write up the remaining items with a target quarter for each.

Frequently Asked Questions

What is technical debt in simple terms?

Technical debt is the accumulated cost of shortcuts and postponed upgrades in your technology. Like financial debt, it charges interest: projects take longer, support costs more, and security risk grows until someone pays it back.

How much does technical debt cost a growing company?

No reliable figure exists for companies your size. McKinsey's survey of large-company CIOs found 10 to 20 percent of new-product technology budgets going to resolving tech debt, and those are self-reported estimates from much larger firms. A practical approach is to ask your IT provider how many hours last year went to fixing or working around old systems, and price that time.

How does this work alongside our existing IT provider?

Your IT provider keeps running day-to-day systems and usually holds the inventory you need. Elevaire handles the security side: identifying risky and unsupported systems, closing protection gaps, and ranking them for leadership. Elevaire works alongside your provider and does not replace it. Pricing for Elevaire Managed Security is predictable and monthly, with no hourly billing.

Is technical debt a security problem or an IT problem?

Both. Most of it is an IT planning issue, such as slow projects and aging equipment. The portion that is unsupported or poorly protected is a security issue, and it is the part cyber insurers and clients ask about.

How do I get started?

Ask your IT provider for a written inventory of systems with their ages and support status. Then flag anything unsupported and score each item for risk and drag. That one document is enough to start a useful conversation about budget and timing.
