Idle Equipment and Underutilized Assets

Walk through most shops and you'll find a machine that hardly runs. It was bought for a customer who left, or for a job that never came back, or as a backup that nobody uses. It still costs money every month.

I don't think idle equipment is always a problem. Sometimes it's a sensible spare. But it should be a decision, made with the numbers, not something that just happened.

Here is how I'd find underutilized assets, put a dollar figure on them and decide what to do.

Why are idle assets a quiet drag on profit?

Because nobody sees them on the P&L. There's no line called "machine we don't use." The cost is spread across depreciation, insurance, maintenance, interest and rent.

For a sense of scale nationally, the Federal Reserve's G.17 industrial production report put U.S. manufacturing capacity utilization at 75.9% for September 2026 (preliminary, released October 16, 2026). The long-run average from 1972 through 2025 is 78.2%. So roughly a quarter of the country's manufacturing capacity isn't being used at any given time. That's an industry-wide number, not a target for your shop, but it shows that unused capacity is normal, not rare.

The question for you isn't the national figure. It's which of your machines are in that unused quarter, and whether you're paying more for them than they're worth to you.

Idle assets also hurt in less obvious ways. They take floor space you might need. They make your balance sheet look heavier than your sales justify, which a lender will notice. And if you finance them, you pay interest on equipment that doesn't earn.

How do you identify underutilized assets in your operation?

Start with a simple measure: capacity utilization. For each major machine, divide the hours it actually ran by the hours it was available.

If you run two eight-hour shifts, five days a week, a machine has about 4,000 available hours a year. If it ran 400 hours, utilization is 10%.

Where do you get run hours? In order of reliability:

1. Machine controllers or monitoring systems that log spindle or cycle time.
2. Job routings and time tickets that record which machine each job used.
3. Your production scheduler's or lead operator's best estimate.

Even the third option is better than nothing for a first pass. You're looking for the outliers, not precision.

For machines that run a lot, OEE (overall equipment effectiveness) tells you more. It combines how often the machine runs, how fast it runs and how many good parts it makes. A machine can be scheduled all day and still waste half its time on setups and scrap.

Look at at least 12 months. Seasonal work can make a machine look idle in one quarter and busy in the next. If it's below 20% or 30% across the whole year, with no clear demand coming, it deserves a closer look.

What does underutilized equipment really cost?

Here's an illustrative press brake. It was bought for $300,000 five years ago and is depreciated over 10 years. There's $150,000 left on the equipment loan at 8%. It ran 400 hours last year.

Annual cost	Amount	Cash?
Depreciation ($300,000 / 10 years)	$30,000	No
Insurance	$2,500	Yes
Maintenance contract	$4,000	Yes
Floor space (600 sq ft at $10)	$6,000	Yes, if you'd use the space
Interest ($150,000 at 8%)	$12,000	Yes
Total	$54,500

That's about $136 for every hour it actually ran ($54,500 / 400). The cash part, leaving out depreciation, is $24,500 a year.

Depreciation isn't cash, and the machine was already paid for in part. But it still matters for pricing. If your overhead rate spreads that $54,500 over every job in the shop, your busy machines are carrying the cost of this one.

Depending on your state, there may be personal property tax on the equipment too. And there's the opportunity cost: what could $150,000 of sale proceeds or 600 square feet of floor do for you elsewhere?

What are your options for underutilized assets?

Once you know the cost, you have several choices. None is right every time.

• Redeploy it. Move work onto it from a bottleneck machine, or move it to another location where it's needed.
• Sell more capacity. Quote work that fits this machine, or offer contract work to other shops. Even pricing near the cash cost can make sense if the alternative is no revenue. Check that the work covers its variable costs first.
• Sell it. Use the money to pay down the loan or fund something that will run. In the example, selling for $150,000 would retire the loan and save $24,500 a year in cash costs.
• Lease it out. Possible for some equipment, though finding a lessee and handling insurance takes effort.
• Keep it on purpose. A backup for a bottleneck machine can be worth the carrying cost. If so, write down why and review it each year.
• Scrap it. If it doesn't run well and nobody will buy it, clearing the space may be worth more than the machine.

I'd make this a quick, written decision for each idle asset. Even "keep for now, review in six months" is better than no decision.

How do idle assets affect your balance sheet and financial ratios?

The main ratio here is fixed asset turnover: revenue divided by net fixed assets. It shows how many dollars of sales each dollar of equipment produces.

Say the shop above has $12 million in revenue and $4 million of net fixed assets. Turnover is 3.0. Sell the press brake at its $150,000 book value and net fixed assets drop to $3.85 million. Turnover goes to about 3.12 with no change in sales. Lenders and buyers notice that trend.

There are accounting points too:

• Overhead and inventory. Under GAAP, fixed production overhead is applied to inventory based on normal capacity. When production is abnormally low, the unabsorbed overhead is expensed in the period instead of being pushed into inventory. Idle equipment makes that more likely.
• Impairment. If an asset group's carrying value can't be recovered from the cash it's expected to produce, GAAP may require a write-down. An idle machine is a signal to check.
• Held for sale. Once you commit to selling, the asset may need to be reclassified and depreciation stops.

Your CPA will handle the exact treatment at year-end. Our job is to flag these early so nothing is a surprise.

What happens at tax time when you sell idle equipment?

Book value and tax value are often very different. Many shops took bonus depreciation or Section 179 on their equipment, so the tax basis may be close to zero even when book value isn't.

When you sell equipment for more than its tax basis, the gain is generally taxed as ordinary income up to the depreciation you already took. That's depreciation recapture under Section 1245. In the example, if the press brake's tax basis is zero and it sells for $150,000, the full $150,000 would generally be ordinary income, even though there's no gain on the books.

If you sell for less than tax basis, you generally have a deductible loss. Either way, the cash from the sale is still cash. It just isn't all yours after taxes.

So plan the timing. A sale in a year with low income, or alongside new purchases that qualify for bonus depreciation, can soften the tax hit. This is general information, not tax advice. Work with your CPA before you sell. We coordinate with your CPA on this as part of our manufacturing tax strategy work.

How do you build a proactive asset review process?

A one-time cleanup helps. A habit helps more. Here's a simple routine:

1. Quarterly: pull run hours for every major machine and flag anything below your threshold.
2. Annually, with the budget: review each flagged asset and make a written keep, redeploy, sell or scrap decision.
3. Before every new purchase: check whether an existing machine could do the work first. This is the cheapest capacity you'll ever find.
4. Keep the fixed asset register clean: remove assets you've sold or scrapped so the books match the floor.

That third step ties straight into your CapEx plan. We cover it in how to build a CapEx plan. And when an upgrade will leave an old machine sitting, factor that into the analysis in how to justify an equipment upgrade.

Frequently Asked Questions

What is a healthy fixed asset turnover ratio for a manufacturer?

It depends a lot on how capital-heavy your work is, so I'd compare yourself to your own trend rather than a general benchmark. If the ratio falls year over year, equipment is growing faster than sales, and idle assets are often part of the reason.

How do I know if a machine is truly idle or just in a slow period?

Look at 12 months of run hours, not one quarter. If it's low across the whole year and no orders are coming that need it, it's underutilized.

Can I deduct a loss when I sell idle equipment?

If you sell for less than the tax basis, you generally have a deductible loss. But many machines have little or no tax basis left after bonus depreciation or Section 179, so a sale often creates taxable recapture instead. Check with your CPA first.

Should I keep an idle machine as a backup?

Sometimes, yes. If it backs up a bottleneck machine and a breakdown would stop key work, the carrying cost can be worth it. Make that a written decision and review it each year.

What utilization rate should a machine run at?

There's no single target. Bottleneck machines should run as much as possible. Others can run lower without a problem. What matters is that you know the number and have a reason for keeping machines that rarely run.
