Labor Cost Percentage: How to Calculate and Control It
Quick Answer
Labor cost percentage = total labor cost divided by revenue, times 100. Total labor cost includes wages, overtime, bonuses, the employer share of payroll taxes, benefits and other employer-paid costs, not just hourly pay. For example, $30,000 in total labor cost on $100,000 in revenue is a 30% labor cost percentage. The number is only as reliable as your time records, so track hours accurately and review it every pay period.
Labor is one of the biggest costs in most small businesses, and one of the easiest to lose track of. A few extra hours here, unplanned overtime there, and by the end of the month your margins are thinner than you expected. Labor cost percentage gives you one simple number to watch: how much of every revenue dollar goes to paying your people.
This guide explains the formula, what to include, worked examples, why your number might be unreliable and how to bring it under control without cutting the people you need.
Note: This is general information, not tax or accounting advice. Check payroll tax and benefit costs with your accountant or payroll provider.
The Labor Cost Percentage Formula
Labor cost percentage = (Total labor cost ÷ Revenue) × 100
Use the same time period for both numbers, such as a week, a pay period, a month or a year. Monthly is the most common for small businesses.
What to Include in Total Labor Cost
The most common mistake is counting only hourly wages. Your real labor cost is higher:
| Cost | Include? | Notes |
|---|---|---|
| Regular wages and salaries | Yes | Hourly pay and salaried pay for the period |
| Overtime | Yes | Often the biggest swing from month to month |
| Bonuses, commissions and shift differentials | Yes | Any extra pay earned in the period |
| Employer Social Security and Medicare | Yes | The employer's share of payroll taxes |
| Federal and state unemployment taxes | Yes | Usually a small amount per employee |
| Benefits | Yes | Health insurance, retirement contributions and other employer-paid benefits |
| Workers' compensation insurance | Yes | Varies by industry and state |
| Paid time off | Yes | PTO hours are paid labor even when no work is done |
| Contractors and temp staff | Your choice | Include them if they do work your employees would otherwise do, and be consistent |
| Owner's pay | Your choice | Many owners track it separately; decide once and stay consistent |
Employer Payroll Taxes
According to the IRS, employers pay 6.2% for Social Security, on wages up to $184,500 per employee in 2026, plus 1.45% for Medicare with no wage cap. Federal unemployment tax (FUTA) is 6.0% on the first $7,000 of each employee's wages, and most employers who pay their state unemployment taxes on time receive a credit that lowers the effective federal rate to 0.6%. State unemployment rates vary.
Worked Examples
Example 1: A Monthly Calculation
| Item | Amount |
|---|---|
| Wages and salaries | $24,000 |
| Overtime | $1,800 |
| Employer Social Security and Medicare (7.65% of $25,800) | $1,974 |
| Benefits | $2,000 |
| Workers' comp and unemployment taxes | $600 |
| Total labor cost | $30,374 |
| Revenue for the month | $100,000 |
| Labor cost percentage | 30.4% |
If you had only counted wages and overtime ($25,800), you'd think labor was 25.8% of revenue, more than four percentage points lower than reality.
Example 2: The Overtime Effect
Same business, but a busy month adds $4,000 in overtime while revenue stays at $100,000. The overtime plus its employer payroll taxes (7.65%, or $306) adds about $4,306, pushing total labor cost to roughly $34,680, or 34.7% of revenue. One month of extra overtime moved the number by more than four points.
Example 3: Per Shift or Per Day
For a restaurant or shop, try it daily. If Saturday's sales were $6,000 and you scheduled 60 hours at an average loaded cost of $22 an hour, labor was $1,320, or 22% of sales. If Tuesday's sales were $2,000 with 40 scheduled hours, labor was $880, or 44%. Daily numbers show exactly where your schedule is out of line with demand.
What Is a Good Labor Cost Percentage?
There's no single right number. Service businesses, where people are the product, naturally run higher labor percentages than businesses that sell physical goods. A healthy target depends on your industry, prices, margins and how much of your work is done by employees versus contractors or equipment.
The most useful benchmark is your own history. Track your labor cost percentage for a few months, find the range where your business is profitable and well-staffed, and watch for movement outside it. Industry associations and your accountant can also give you a sense of what's typical for businesses like yours.
Why Your Labor Cost Number May Be Unreliable
Labor cost percentage is only as good as the data behind it. Common problems:
- Inaccurate time records. Handwritten timesheets, missed punches and rounding errors throw off wages and overtime.
- Auto-deducted breaks that weren't taken, which understate hours worked.
- Leaving out employer costs, such as payroll taxes, benefits and workers' comp.
- Mismatched periods, such as a month of revenue against two biweekly payrolls that don't line up.
- Spreadsheet errors from manual copy-and-paste or a broken formula.
Accurate time tracking is the foundation. See how to track employee hours for setup tips.
How to Control Labor Costs (Without Cutting Corners)
- Schedule to demand. Use sales or bookings by hour and day to staff busy times well and slow times lightly. See how to make a work schedule.
- Watch overtime weekly, not at the end of the month. Under federal law, non-exempt employees earn time and a half for hours over 40 in a workweek, and some states add daily overtime, so a few long shifts add up fast. See overtime laws by state.
- Compare scheduled to actual hours. Shifts that run long every day are a scheduling or workflow problem.
- Cross-train. Employees who can cover more than one role reduce overstaffing and overtime.
- Fix workflow bottlenecks. Labor cost often rises because work takes longer than it should, not because you have too many people.
- Reduce turnover. Hiring and training new people is expensive, and new hires take time to reach full speed.
- Review it every pay period so you can correct course quickly.
Labor Cost Percentage vs. Other Labor Metrics
| Metric | Formula | Best for |
|---|---|---|
| Labor cost percentage | Total labor cost ÷ revenue | Overall labor efficiency |
| Revenue per labor hour | Revenue ÷ hours worked | Comparing days, shifts or locations |
| Overtime percentage | Overtime hours ÷ total hours | Spotting scheduling gaps |
| Labor cost per unit | Labor cost ÷ units, jobs or customers | Pricing and job costing |
| Scheduled vs. actual hours | Actual hours ÷ scheduled hours | Schedule accuracy |
A Simple Labor Cost Tracking Template
| Period | Revenue | Wages + OT | Taxes + benefits | Total labor | Labor % |
|---|---|---|---|---|---|
| Week 1 | $24,000 | $6,100 | $1,050 | $7,150 | 29.8% |
| Week 2 | $22,500 | $6,400 | $1,090 | $7,490 | 33.3% |
| Week 3 | $26,000 | $6,050 | $1,040 | $7,090 | 27.3% |
| Week 4 | $25,500 | $6,700 | $1,130 | $7,830 | 30.7% |
Week 2 stands out: revenue was lower and labor was higher. That's the week to look at, maybe a slow week that was scheduled like a busy one, or overtime from a call-out.
How to Calculate Labor Cost Percentage Step by Step
- Pick the period. Choose a week, pay period or month. Use the same period for labor and revenue.
- Add up gross wages. Include regular pay, overtime, bonuses, commissions and paid time off for the period.
- Add employer payroll taxes. Include the employer share of Social Security and Medicare, plus federal and state unemployment taxes. Your payroll provider or accountant can give you exact figures.
- Add benefits and insurance. Include the employer-paid part of health insurance, retirement contributions and workers' compensation.
- Total it. That's your total labor cost.
- Divide by revenue for the same period and multiply by 100.
Do it the same way every time. A consistent method matters more than a perfect one, because the goal is to see changes over time.
Fully Loaded Hourly Cost
Labor cost percentage looks at the whole business. To plan schedules and price jobs, it helps to know what one hour of an employee's time really costs, often called the fully loaded hourly cost.
Fully loaded hourly cost = (Annual wages + employer taxes + benefits + other employer costs) ÷ Annual hours worked
For example, an employee paid $20 an hour who works 2,000 hours a year earns $40,000. Add employer Social Security and Medicare at 7.65% ($3,060), unemployment taxes, workers' comp and benefits, say $5,000 combined in this example, and the total is about $48,060. Divided by 2,000 hours, the fully loaded cost is about $24.03 an hour, roughly 20% more than the hourly wage. Your actual figures will depend on your state, industry and benefits.
This number is useful for quoting jobs, deciding whether overtime or a new hire makes more sense, and comparing the cost of different schedules.
Labor Cost Percentage for Different Business Types
| Business type | What drives labor cost | Useful extra metric |
|---|---|---|
| Restaurants and cafes | Staffing to hourly demand, overtime on busy days | Labor cost per shift or day |
| Retail | Coverage during open hours, seasonal peaks | Sales per labor hour |
| Home services and trades | Travel time, job overruns, crew size | Labor cost per job |
| Professional services | Billable vs. non-billable hours | Utilization rate |
| Healthcare and care services | Required staffing levels, shift coverage | Labor cost per patient or visit |
| Cleaning and facilities | Hours per site, travel between sites | Labor cost per site |
Every business type has its own pressure points. Pick the extra metric that matches yours and track it next to your labor cost percentage.
Common Labor Cost Mistakes
- Comparing gross wages to revenue and calling it total labor cost.
- Switching methods from month to month, so trends are meaningless.
- Cutting hours without checking service. A lower percentage isn't a win if customers wait longer or quality slips.
- Ignoring off-the-clock work. Non-exempt employees must be paid for all hours worked. Unrecorded work hides real labor cost and can create legal risk. The U.S. Department of Labor's Fair Labor Standards Act page explains the federal rules.
- Looking only at the monthly number. Weekly or daily views catch problems while they can still be fixed.
A Monthly Labor Cost Review
A short monthly review keeps labor costs in check without a lot of extra work:
- Calculate labor cost percentage for the month and compare it to the last three months.
- Look at overtime hours by person and by week. Were they planned?
- Compare scheduled hours to actual hours worked.
- Check for missed punches, edits and unusual time entries. See timesheet edit form.
- Note anything unusual, such as a holiday, a big job or a staff shortage, so next year's comparison makes sense.
- Pick one change to try next month.
Overtime rules vary by state, so check the rules where your team works with our overtime laws by state guide.
Overtime vs. Hiring: Which Costs Less?
When overtime keeps climbing, many owners ask whether it would be cheaper to hire. A simple comparison helps:
| Overtime | New hire | |
|---|---|---|
| Hourly cost | 1.5 times the regular rate for non-exempt employees over 40 hours in a workweek, plus employer taxes | Regular rate plus employer taxes and benefits |
| Up-front cost | None | Recruiting, onboarding and training time |
| Flexibility | Easy to scale up or down | Harder to reduce once hired |
| Risk | Burnout, mistakes and turnover if it lasts too long | Not enough work if demand drops |
Short bursts of overtime are often the cheaper choice. Steady overtime week after week is usually a sign you need more coverage, through a new hire, part-time help or better scheduling. Use your fully loaded hourly cost to run the numbers for your business.
Should You Use Revenue or Gross Profit?
Most businesses calculate labor cost percentage against revenue because it's simple and easy to compare over time. Some businesses with high material or product costs also look at labor as a percentage of gross profit (revenue minus cost of goods sold), which shows how much of the money left after materials goes to labor. Either is fine. Pick one, label it clearly and use it every time.
Start With Accurate Hours
Every part of the labor cost formula depends on hours: regular wages, overtime, PTO and the payroll taxes that follow them. If start and end times are guessed, rounded or written in after the fact, your labor cost percentage will be off before you even begin. Accurate digital time records, with a clear process for fixing missed punches, give you a number you can trust and act on. Then the monthly review becomes a quick check instead of a cleanup project.
