How to Calculate Labor Cost Percentage

What does labor cost percentage measure?

Labor cost percentage answers one question: out of every dollar that came in, how much went to paying the people who earned it? A café at 24% spends 24 cents of each sales dollar on labor. It is the number owners and managers of restaurants, shops and service businesses watch most closely, because labor is usually one of the largest costs they can actually adjust week to week.

The formula is one division:

Labor cost % = total labor cost ÷ total sales × 100

The division is the easy part. The number goes wrong in the inputs: hours added incorrectly from a timesheet, a labor figure that leaves costs out one week and includes them the next, or sales and labor that cover different dates.

How do I calculate labor cost percentage step by step?

1. Choose the period. A day, a week, a pay period or a month. The labor cost and the sales must cover exactly the same dates.
2. Total each person’s hours in H:MM. Add their shifts as hours and minutes, carrying every 60 minutes into an hour. Our guide to adding hours and minutes shows the carrying.
3. Convert each total to decimal hours. Divide the minutes by 60. 38:45 is 38.75 hours, not 38.45.
4. Multiply by each pay rate and add the results. That sum is your wage cost for the period.
5. Add any other labor cost you count. Overtime premiums, salaried pay, employer payroll taxes and benefits, if your definition includes them (more on that below).
6. Total net sales for the same period. Sales after discounts and refunds, without sales tax or tips.
7. Divide labor cost by sales and multiply by 100. Round to two decimal places at the very end.

Worked example: one week at a five-person café

A café took in $9,480.00 in net sales for the week. Five hourly employees worked it. Ana, for example, worked five shifts: 8:15 + 7:45 + 7:30 + 8:00 + 7:15. The minutes are 15 + 45 + 30 + 0 + 15 = 105, which is 1:45. The hours are 8 + 7 + 7 + 8 + 7 = 37. Together that is 38:45.

The hours. 38:45 + 32:20 + 27:30 + 21:15 + 14:40. The minutes are 45 + 20 + 30 + 15 + 40 = 150, which is 2:30. The hours are 38 + 32 + 27 + 21 + 14 = 132. Together that is 134:30, or 134.5 decimal hours.

The wages. Each person’s decimal hours times their rate: $697.50 + $533.50 + $467.50 + $329.38 + $220.00 = $2,247.88. (Dee’s 21.25 × $15.50 is $329.375, rounded to the cent.) Because the rates differ, you cannot multiply the 134:30 team total by one rate; each person is priced separately and the dollars are added.

The percentage. $2,247.88 ÷ $9,480.00 = 0.23712, and × 100 that is 23.71%. A little under 24 cents of every sales dollar went to hourly wages.

Why can’t I type 38:45 into a calculator as 38.45?

Because minutes are sixtieths of an hour, not hundredths. 45 minutes is three quarters of an hour, 0.75, so 38:45 is 38.75 hours. Typing the clock time as a decimal quietly drops time from every line that has minutes in it.

The shortcut reports 133.50 hours instead of 134.5 and $2,231.33 instead of $2,247.88, which makes the week look like 23.54% instead of 23.71%. That is $16.55 of labor the report does not know about — and the payroll that actually goes out will be the larger number. The full conversion is in our hours to decimal guide.

What counts as labor cost?

There is no single official definition, which is why two businesses quoting “their labor percentage” are often not comparing the same thing. The common versions build on each other. Suppose the café also has a manager on a $900.00 weekly salary, and that employer payroll taxes and benefits for the week come to $412.50 (an example figure — yours come from your payroll report).

Same week, same people, three honest answers almost fourteen points apart. None is wrong. Hourly wages only is the version you can calculate straight from a timesheet and act on when you write next week’s schedule. Fully loaded is closer to what the labor really costs the business. What matters is that you pick one definition, label it, and use it every period, so that a change in the number means something changed in the business rather than in the arithmetic.

Whichever version you use, overtime premiums and any paid time off or shift premiums paid in the period belong in it. They are labor cost even when no extra sales came with them.

What counts as sales?

Use net sales for the same dates: what customers paid for goods and services, after discounts, comps and refunds.

• Leave out sales tax. You collect it and pass it on; it was never your revenue.
• Leave out tips. They belong to the staff. (Dividing them up is its own calculation — see splitting a tip pool by hours worked.)
• Match the dates exactly. A payroll week that runs Sunday to Saturday set against a sales report that runs Monday to Sunday compares six shared days and two that do not belong together.

Gross sales with tax included make the percentage look better than it is. If the café’s register total were $10,238.40 with tax, the same wages would show as 21.96% — a flattering number that describes money the business does not keep.

How does overtime change the percentage?

Overtime adds cost faster than it adds hours. Suppose Ana had covered an extra five-hour shift and finished the week at 43:45 instead of 38:45. Under the common time-and-a-half-over-40 arrangement, her week splits into 40:00 at $18.00 and 3:45 at $27.00:

40 × $18.00 = $720.00 plus 3.75 × $27.00 = $101.25, a total of $821.25.

The same 43:45 at straight time would be $787.50, so $33.75 of that is premium. Team wages rise from $2,247.88 to $2,371.63, and if sales stay at $9,480.00 the percentage moves from 23.71% to 25.02%. Had those five hours gone to Eli at $15.00, they would have cost $75.00 rather than $123.75. That is the sort of decision this number exists to inform. The split itself is covered in how to calculate overtime.

How many labor hours can I schedule for a target percentage?

Run the formula backwards. Start from the sales you expect and the percentage you are aiming for:

1. Labor budget = forecast sales × target percentage. A forecast of $8,200.00 at a 24% hourly-wage target is $1,968.00.
2. Average hourly rate = wages ÷ hours from a recent, typical week. Here $2,247.88 ÷ 134.5 = $16.71 (16.7129 before rounding).
3. Hours = labor budget ÷ average rate. $1,968.00 ÷ $16.7129 = 117.75 hours.
4. Convert back to H:MM. 0.75 × 60 = 45 minutes, so the budget is 117:45 — not 117:75, and not 117 hours 7 minutes.

That is 16:45 fewer than the 134:30 worked in the example week, which tells you how much schedule has to come out for a slower week to hold the same percentage. The average rate is a weighted one, so it shifts if the mix of who works changes; recalculate it when the roster does.

What is sales per labor hour?

It is the same relationship measured in hours instead of dollars:

Sales per labor hour = total sales ÷ total hours worked

For the example week, $9,480.00 ÷ 134.5 = $70.48 of sales for every hour on the clock. Because it ignores pay rates, it is useful for comparing shifts or days staffed by different people, and it is not disturbed by a raise. Use decimal hours here too: dividing by 134.30 instead of 134.5 gives $70.59, a figure that overstates how productive the week was.

Should I calculate it daily or weekly?

Weekly is the usual choice. It matches how schedules are written and how overtime is counted, and it smooths out the difference between a quiet weekday and a packed weekend. Daily figures are worth a look, but they swing:

Notice the bottom row. The two days together are 22.71%, found by adding the dollars and dividing once. Averaging the two percentages gives (29.85 + 19.59) ÷ 2 = 24.72%, which is wrong, because it treats a $980 day as if it weighed the same as a $2,240 day. Never average percentages; add the wages, add the sales, then divide. The same rule applies when rolling weeks into a month.

What is a good labor cost percentage?

There is no single number that is good for everyone, and you should be wary of any article that hands you one. The right figure depends on the industry, the service model, local wages and prices, and above all on which version of “labor cost” is being measured — as the table above shows, one week can be 23.71% or 37.56% depending on what is counted.

The comparison that is always valid is against yourself: the same business, the same definition, week after week. A percentage that drifts up while sales hold steady is telling you hours or rates grew. One that drifts up while hours hold steady is telling you sales fell. Either is worth knowing before the month closes.

What mistakes skew the number?

• Typing H:MM as a decimal. 38:45 is 38.75, not 38.45. Across the example team that hides $16.55 of wages.
• Using scheduled hours instead of worked hours. People stay late and start early. Total the actual punches.
• Multiplying team hours by one rate. With mixed rates, price each person and add the dollars.
• Forgetting the overtime premium. Hours over the threshold cost more than the base rate.
• Mismatched periods. Labor for one set of dates over sales for another.
• Including sales tax or tips in sales. Both make the percentage look lower than it is.
• Changing the definition. Wages only one month and fully loaded the next produces a jump that never happened.
• Averaging daily percentages. Add the dollars first.

Frequently asked questions

How do you calculate labor cost percentage?

Divide total labor cost for a period by total sales for the same period and multiply by 100. A week with $2,247.88 in hourly wages and $9,480.00 in sales is 2,247.88 ÷ 9,480.00 × 100 = 23.71%.

What is included in labor cost?

At minimum, gross wages for the hours worked, including overtime premiums. A fully loaded figure adds salaried pay, employer payroll taxes, benefits and paid time off. Pick one definition and keep it the same every period so the percentages stay comparable.

What is a good labor cost percentage?

There is no single good number. It depends on the industry, the service model, local wages and prices, and on whether the figure is wages only or fully loaded. The most useful comparison is your own percentage, calculated the same way, across past weeks.

Should sales include sales tax and tips?

No. Use net sales: what customers paid for goods and services after discounts, comps and refunds, without sales tax. Tips belong to the staff and sales tax belongs to the government, so neither is revenue for this calculation.

How do I work out how many labor hours I can schedule?

Multiply forecast sales by your target percentage to get a labor budget, then divide by your average hourly rate. $8,200.00 in forecast sales at a 24% target is $1,968.00, and at an average of $16.71 an hour that is 117.75 hours, which is 117:45.

Is labor cost percentage calculated daily, weekly or monthly?

Any period works as long as the labor cost and the sales cover exactly the same dates. Weekly is the most common because it matches schedules and the overtime workweek. Daily figures swing widely, so combine days by adding the dollars, not by averaging the percentages.
