Should You Close Your Restaurant During Slow Hours?

Before closing a slow restaurant shift, compare the costs you would actually stop paying with the money those orders leave after food and order-related costs. A high labor percentage is a warning to investigate. It does not, by itself, tell you whether shorter hours will improve cash.

If you pay $50 in labor to sell $100 of food, labor is 50%. But if those orders use $35 of ingredients, packaging and transaction fees, they leave $65 before labor. After the $50, $15 remains toward other costs. Closing that hour could make you worse off if the rent stays due and the staff still need to do the prep.

The examples below are fictional U.S. planning examples. The hourly pay, employer costs and percentages are assumptions, not wage recommendations or industry targets.

First, make the hourly numbers mean something

Use net sales: food and drink revenue after discounts and refunds, excluding sales tax and tips passed to staff. A $20 menu item sold with a $5 restaurant-funded discount contributes $15 to net sales, not $20. A delivery app's bank payout after fees is a different number again. Record the sale and the fees separately so neither disappears nor gets counted twice.

For each service period, collect sales, orders, paid hours and full employer labor cost. Full employer cost includes gross wages plus employer taxes, insurance, benefits and other costs that apply. It is not the employee's take-home pay. Keep opening prep, receiving and closing work visible even when the POS records no sales during those hours.

Suppose two employees each cost the business $25 per paid hour, including the employer costs in this example. Two people × $25 = $50 per hour.

• At $100 sales: $50 ÷ $100 × 100 = 50% labor.
• At $200 sales: $50 ÷ $200 × 100 = 25% labor.
• At zero sales: the $50 cost remains, but a labor percentage cannot be calculated because you cannot divide by zero.

The same staffing produces very different percentages as sales change. Also check the full day and week: prep may support dinner sales several hours later. Use the free shift and labor planner to total paid hours and overtime by employee before judging the schedule.

A labor target and a decision to close are different calculations

If your plan sets labor at 30% of sales, convert 30% to 0.30 and calculate $50 ÷ 0.30 = $166.67 of hourly sales. That is the sales needed to hit your chosen labor target with this staffing. It is not the point at which every sale below that number becomes worthless.

Now suppose ingredients, packaging and payment fees together use 35% of sales. Out of every $100 sold, those costs use $35 and leave $65. The contribution margin is 65%, or 0.65: the portion of sales left for labor and costs not yet included.

To cover only $50 of labor at that margin, the sales calculation is $50 ÷ 0.65 = $76.92, approximately. Add the other costs caused by staying open before using that as an operating threshold. And keep the whole restaurant's rent, debt and owner pay in the full business plan.

This explains how an hour can miss a 30% labor target yet still help pay the bills. The target is useful for planning; the closing decision needs a comparison of what changes.

Work one slow period all the way through

Consider a three-hour afternoon period with $180 net sales. Assume the same two employees cost $50 an hour, order-related costs are 35% of sales, and staying open causes $15 of additional costs such as equipment energy and cleaning supplies.

Three-hour period	Calculation	Amount
Net sales	POS, after discounts/refunds	$180
Food, packaging and fees	$180 × 0.35	−$63
Contribution before labor	$180 − $63	$117
Scheduled employer labor cost	3 hours × $50	−$150
Other added costs of opening	Example estimate	−$15
Result before unchanged overhead	$117 − $150 − $15	−$48

That looks like a reason to close. But first ask how much of the $150 payroll would disappear.

Case A: all three hours of payroll really go away

Assume you can lawfully schedule both employees three fewer hours, with no replacement work, extra pay obligation or effect on other services. Closing saves $150 labor + $15 other costs = $165. It loses $117 of contribution from those orders. The cash improvement is $165 − $117 = $48 for that period.

At the same 65% contribution margin, the period needs $165 ÷ 0.65 = $253.85 of sales to cover those avoidable costs. At a $20 average order, that is 12.69 orders, so 13 whole orders across the three hours. This is a planning calculation, not evidence that 13 customers will arrive.

Case B: prep and cleaning mean most payroll stays

Now assume closing the doors saves only two employee-hours in total, not six. Perhaps each person leaves one hour earlier, while the remaining work still has to be done. Payroll falls by 2 × $25 = $50. With the same $15 of other savings, closing avoids $65.

You still lose $117 of contribution. The change is $65 − $117 = −$52: closing makes cash $52 worse for that period. The remaining $100 payroll is still owed. An allocated shift result of negative $48 did not mean all its costs were removable.

Here the sales needed to justify staying open are $65 ÷ 0.65 = $100 across the period, under these assumptions. The $180 sales exceed that. This does not prove the restaurant is profitable; it answers only whether this particular closure helps.

Only count savings that will reach the bank account

Mark each cost as saved, still paid, or unknown under the new schedule. Unknown is not zero.

• Labor: compare the whole proposed week with the current week. Moving prep from 3 p.m. to 10 a.m. does not save hours. Moving it into overtime may cost more. A salaried manager remaining on payroll is not an hourly cash saving.
• Owner work: covering a shift yourself may reduce employee payroll, but your time is not free. Record the hours and the work or outside income you give up. Show both the cash effect and whether the arrangement is sustainable.
• Utilities: refrigeration usually continues while the doors are closed. Use the portion of the bill that changes, not the entire day's electricity allocation.
• Food: include costs that disappear with lost orders. Count any separate reduction in spoilage once, with evidence. If the same food is still prepared and then discarded, the ingredient cost was not avoided. If staff still do the same prep elsewhere in the week, those hours were not saved either.
• Rent, debt and contracts: closing a few hours does not automatically reduce rent, a loan payment or software fees. Check required operating hours in the lease and franchise agreement before testing a change.

Do not ask staff to clock out while they keep preparing, cleaning or waiting to serve. The U.S. Department of Labor's hours-worked guidance explains compensable work and waiting time. Sending someone home can also leave pay obligations: California's reporting-time-pay guidance, for example, describes circumstances requiring pay when an employee receives less than the scheduled work. Rules and exceptions vary. Confirm your actual schedule-change costs before counting them as savings.

Check what happens to the customers

The examples assume every sale in the closed period disappears and other periods stay the same. Your test may show something different.

If $60 of those $180 sales moves to another period at the same 65% margin, with no extra labor, lost contribution is only ($180 − $60) × 0.65 = $78. Case B still saves $65, so closing is $13 worse, rather than $52 worse. Do not assume customers will change their routines; measure it.

Closing can also lose orders just before or after the new hours, disrupt catering pickup, or damage confidence in your posted hours. Track the whole day and week. If you change the menu, discounts or delivery mix at the same time, recalculate contribution rather than carrying the old 65% forward.

A worksheet for changing your hours

Use one comparison week and total every proposed closed period within it. Enter weekly dollars on every line below; do not subtract a whole week’s payroll savings from one afternoon’s lost sales. For example, if Case A repeats unchanged on five afternoons, the weekly improvement is 5 × $48 = $240. Start with several comparable weeks of POS and payroll records. For a new opening, label the figures as forecasts and replace them with actual results as they arrive.

1. Proposed closed period: day, start time, end time and frequency: ____
2. Net sales in all proposed closed periods that week: $____; sales expected to move elsewhere in the same week: $____
3. Contribution lost after food, packaging, fees and other order costs: $____
4. Payroll actually avoided across the full week: $____, after retained prep, closing work and applicable pay obligations
5. Other costs actually avoided: $____; additional costs caused elsewhere: $____
6. Expected cash change: avoided payroll + other avoided costs − lost contribution − additional costs = $____
7. Restrictions and service checks: approved operating hours, required coverage, food-safety procedures, pickup commitments and accurate posted hours: ____
8. Test dates, owner and review date: ____; evidence needed to keep, adjust or reverse the change: ____

When the assumptions are ready, test a defined change for comparable services, with any required notice. Update your website, map listings, ordering apps and door sign together. Watch sales, payroll actually paid, waste, late orders and customer complaints. Keep a record of what changed so you can compare fairly.

If the full week still cannot pay its bills, a better slow-hour schedule is only one part of the answer. Use the free P&L builder and restaurant break-even calculator to check the whole operation, and put upcoming payments into the cash calendar. Review commitments and options while you still have time and cash to act. Money already spent is not a reason to keep accepting avoidable new losses.
