How to Build a Labor Cost Budget for Manufacturing

Labor is usually the biggest cost in a shop that you can actually control. Yet a lot of labor budgets are last year's payroll plus a raise. That's not a budget. It's a guess with a percentage on it.

A real labor budget starts from what you plan to make. It turns units into hours, hours into people, and people into dollars with the full cost loaded in. Then you check it every month.

Here is how I build one, step by step, with an illustrative example you can follow.

Why do manufacturing labor budgets fall short?

In my experience, it comes down to a few things.

• They start from payroll, not production. If sales are planned 15% higher, the labor budget needs to say how many more hours that takes. A flat 3% raise doesn't answer it.
• They budget wages, not cost. Payroll taxes, benefits, workers' comp and PTO get left out or tucked into another line.
• They treat all labor the same. Direct labor moves with volume. Indirect labor mostly doesn't. One number for both hides that.
• Nobody looks at it again. The budget gets built in December and opened again next December.

Each step below fixes one of these.

Step 1: Separate direct labor from indirect labor

Start by sorting every role. Direct labor is the people who make the product and whose hours go on a job. Indirect labor is plant support: supervisors, maintenance, material handling, quality. Office staff are a third group and belong in operating expenses.

The reason to split them is that they're budgeted differently. Direct labor is driven by the production plan. Indirect labor is driven by headcount decisions, and it stays about the same whether you ship 4,000 units or 4,500.

If your books don't split them today, fix that first. We walk through it in direct vs. indirect labor costs.

Step 2: Calculate your fully loaded labor rate

The wage is only part of what an hour costs. The rest is the burden: employer taxes, insurance and benefits. The burden rate is that extra cost as a percentage of wages.

For 2026, the federal employer payroll taxes are:

• Social Security: 6.2% of wages up to $184,500 per employee
• Medicare: 1.45% of all wages, with no cap
• FUTA: 0.6% on the first $7,000 per employee, so $42, after the normal state credit. It's more in credit-reduction states.

State unemployment tax depends on your state and your claims history, so use the rate on your state notice. Workers' comp depends on your class codes. Health insurance and retirement match are whatever your plans cost.

Here's an illustrative build for 20 operators at $24 per hour, each paid 2,080 hours a year:

Item	Basis (illustrative)	Annual cost
Wages	41,600 paid hours x $24	$998,400
Social Security and Medicare	7.65% of wages (all under the wage base)	$76,378
FUTA	$42 x 20	$840
State unemployment	Assume $300 per employee	$6,000
Workers' comp	Assume 3% of wages	$29,952
Health insurance	Assume $7,200 per employee	$144,000
401(k) match	Assume 3% of wages	$29,952
Total		$1,285,522

The burden here is about 28.8% on top of wages ($287,122 / $998,400). Your number will be different. The point is to calculate it, not borrow someone else's.

One more thing. The 2,080 paid hours include vacation, holidays and time that isn't on a job. So the cost per productive hour is higher than the cost per paid hour. We'll get to that in the next step. The full employee-level version is in the fully loaded cost of a manufacturing employee.

Step 3: Link your labor budget to your production plan

This is the step that turns a guess into a budget.

Start with the units in your sales and production plan. Multiply by the standard labor hours per unit. That gives you the direct hours you need.

In the illustrative shop, the plan is 48,000 units at 0.75 hours each. That's 36,000 direct hours.

Next, figure out how many productive hours one operator gives you in a year. Start from 2,080 paid hours. Take out vacation, holidays, training, meetings, cleanup and waiting. In this example we'll use 1,800 productive hours per operator.

36,000 hours divided by 1,800 is 20 operators. That's where the 20 in the table came from.

Now the full cost per productive direct hour is $1,285,522 / 36,000, or about $35.71. Per unit, labor is about $26.78. Those are the numbers to use in your quotes and standard costs, not the $24 wage.

If the plan has 52,000 units next year, the same math says you need about 21.7 operators. That's a hiring decision you can see coming in December, not one you find out about in May.

Indirect labor is simpler. List the roles and the people, apply the same burden build, and only change it if you plan to add or cut a position. Tie it to the same plan so a big jump in volume prompts the question: do we need another material handler or another shift lead?

Step 4: Account for overtime, turnover and seasonal swings

Overtime. Under federal law, non-exempt employees get at least time and a half for hours over 40 in a workweek. Some states add their own rules. So an overtime hour at $24 costs $36 in wages before taxes.

I think you should budget overtime on purpose instead of hoping it won't happen. Look at your last 12 months. If your shop ran 1,500 overtime hours, that's $54,000 in wages and about $58,131 with Social Security and Medicare. Put it in the budget as a separate line so you can see it.

A budgeted number also becomes a ceiling. If overtime runs over every month, that tells you something about staffing or scheduling.

Turnover. Every operator who leaves costs money to replace. Here's an illustrative estimate:

• Recruiting and onboarding: $1,500
• Trainer time: 80 hours at $35 = $2,800
• Lost output while the new person learns: 240 hours at half speed = 120 hours x $35.71 = about $4,285

That's about $8,585 per replacement. If you replace five operators a year, budget about $43,000 for it. It's real money, even if it never shows up on one line of the P&L.

Seasonal swings. Spread the annual budget by month using the production plan, not by twelve. If the plan is heavy in spring and light in December, the labor budget should be too. That's also where you decide in advance whether to use overtime, temps or a hiring push for the busy months.

Step 5: Build in a monthly variance review

A budget nobody checks is a document, not a tool. I like a short monthly review after the close, ideally the same week.

Compare actual labor to the budget, but flex the budget to what you actually produced. If you made fewer units, you should have used fewer hours. Then split the difference into two pieces:

• Labor rate variance: did we pay more per hour than planned?
• Efficiency variance: did we use more hours than the work should take?

Illustrative March: the plan for the units actually produced was 3,000 standard hours at $24, or $72,000. Actual was 3,300 hours at an average of $24.80, or $81,840.

Variance	Calculation	Amount
Rate	($24.80 - $24.00) x 3,300 hours	$2,640 unfavorable
Efficiency	(3,300 - 3,000) x $24.00	$7,200 unfavorable
Total	$81,840 - $72,000	$9,840 unfavorable

The rate piece is usually overtime or a raise that wasn't planned. The efficiency piece is where the operations questions are: setups, downtime, rework, waiting on material. Bring the plant manager to that part of the review. They'll know the answer faster than the numbers will.

If the same variance shows up three months in a row, it's not noise. Either fix the cause or fix the standard.

How Accounovation helps manufacturers take control of labor costs

We build the labor budget from your production plan, load it with your real taxes and benefits, and spread it by month. Then we review actual against budget every month with you and your plant manager. That's part of our budgeting and forecasting work.

On the cost side, we set up payroll so direct and indirect labor post to the right accounts, which is part of our manufacturing accounting work. If you want help using the budget for bigger decisions like adding a shift, our fractional CFO work covers that.

If you already have a budget and the problem is that labor keeps running over, start with strategies for managing labor costs in manufacturing. And if the variances are big on specific jobs, labor cost control and operational efficiency goes into the shop-floor side.

Frequently Asked Questions

What should labor cost as a percentage of revenue in manufacturing?

There isn't one right number. It depends on how automated you are, your product mix and how much of your work is setup. The more useful test is your own trend: if labor as a percentage of revenue is rising and output isn't, something changed.

How do I budget for overtime without encouraging it?

Budget it from your actual history and show it on its own line. Pair it with a simple approval rule. If it runs over the budget for a few months, look at staffing or scheduling instead of just paying it.

Should indirect labor be part of cost of goods sold?

Indirect plant labor, like supervisors, maintenance and material handlers, is manufacturing overhead and goes into COGS. Office and admin labor goes into operating expenses.

How many productive hours should I assume per operator?

Use your own timecard data if you have it. Start with 2,080 paid hours and subtract PTO, holidays, training, meetings and non-job time. The answer is usually well below 2,080, and using 2,080 will understate your cost per hour.

How often should I update the labor budget?

Build it once a year and compare to it every month. If volume or wages change a lot mid-year, update the forecast for the rest of the year but keep the original budget so you can see what moved.
