Should Your Restaurant Offer a Meal Deal? Work Out the Extra Orders It Needs

Only if the orders it adds earn more than it gives away. A meal deal doesn't just reach new guests. Regulars who would have come in anyway use it too, and whenever one of them pays less than usual, you keep less. Add any extra staff or signs, and the new orders have to cover all of that before the deal makes you a dollar.

In the fictional sandwich shop below, a $12 lunch combo needs 45 added lunch orders a week just to break even. That's about 19% more lunch traffic. If the deal brings in 30 added orders instead, the shop sells 126 combos a week, lunch feels busier, and it ends up $103.96 a week worse off than with no deal at all. So work out your break-even number before you start, run the deal for a fixed period, and judge it by total contribution, not by how many people redeem it.

On September 17, 2026, the National Restaurant Association published its third-quarter 2026 consumer survey. Forty percent of consumers said they were using more discounts or value promotions than usual, up from 35% in the second quarter. In the same survey, 36% said they had shifted toward less expensive restaurants and 34% said they were ordering fewer add-ons such as desserts and beverages. The Association's commentary also says many operators are reluctant to pass along higher costs for fear of weakening already-soft traffic. That's why a deal is tempting right now. The survey doesn't tell you whether one will pay at your restaurant. More guests looking for deals can mean more new customers, and it can also mean more of your regulars trading down to the cheaper option.

The calculation

Compare the deal with doing nothing, over the same days and hours. Three numbers decide it:

• Added orders. Orders that would not have happened without the deal. Each one earns the deal's contribution: the deal price minus food, packaging and payment fees.
• Switching orders. Regulars who would have ordered anyway and buy the deal instead. Each one costs you the difference between what their usual order left you and what the deal leaves you.
• Extra costs. Added labor, signs, printing and anything else you pay only because the deal is running.

Change vs. no deal = (added orders × deal contribution)
                   − (switching orders × lost contribution per switch)
                   − extra costs

Shortfall               = (switching orders × lost contribution per switch)
                          + extra costs

Break-even added orders = shortfall ÷ deal contribution, rounded up to a whole order
                          (0 if the shortfall is zero or less)

Contribution here means what's left from an order after the costs that come with it: food, packaging and fees charged as a share of the check. It isn't profit. Rent, salaries and other bills that don't change because of the deal still have to come out of it, but they stay out of this comparison because you pay them either way.

This is the SBA's break-even formula, fixed costs ÷ (price − variable cost per unit), with two changes. The deal's own extra costs take the place of fixed costs, and the money lost on switching regulars gets added to them. If switching leaves you more instead, that gain gets subtracted.

Step 1: Work out what one deal order leaves you

Here's a fictional sandwich shop. It's open for lunch Monday through Thursday and averages 60 orders a service, or 240 a week. It wants to try a $12 lunch combo for four weeks: any sandwich, a bag of chips and a fountain drink. Bought separately, those cost $11, $2 and $3, so the sign would say "save $4." Every sandwich is the same price to keep the example simple, and payment fees are assumed to be 3% of the check.

If you also sell the deal through delivery apps or another channel with different fees, work out that version separately. One contribution figure rarely fits every channel.

Step 2: Work out what each switching regular costs you

The sign says $4 off, but that isn't what a switching regular costs you. It depends on what they used to buy. Pull the item mix for the same days and hours from your POS. The shop's lunch orders break down like this:

Each row is that order's contribution minus the deal's $7.04. The sandwich-only guest pays $1 more for the combo, and the chips, drink and extra fee use up almost all of that dollar. The guest who already buys all three pays $4 less and leaves you $3.88 less, because the fee drops 12 cents. The sandwich-and-drink guest pays $2 less and also takes chips that cost you 55 cents, so the switch costs you $2.49, more than the price cut.

If switchers buy in the same mix as everyone else at lunch, weight each row by its share: 0.25 × −$0.02 + 0.50 × $2.49 + 0.25 × $3.88 = $2.21 lost per switching order. If you can't split your orders this way, at least compare the deal with what your regulars actually spend at lunch, not with the full price of everything in the bundle.

Watch the mix, too. The guests with the most reason to switch are the ones who save the most, and they cost you the most when they do. This shop has only 60 full-set orders a week, so at the base switching rate below (96 switching orders), the worst case is all 60 of them switching plus 36 sandwich-and-drink orders: 60 × $3.88 + 36 × $2.49 = $232.80 + $89.64 = $322.44 a week. With the extra costs from step 3, the shop would then need 61 added orders a week, not 45.

Step 3: Add what it costs to run

The shop's current crew handles about 70 orders a lunch service well. To leave room for more, it plans one extra hour of help per service, which it expects to raise that to about 80. That's 4 hours a week at a full employer cost of $22 an hour, or $88 a week. Signs and a menu board insert cost $60, which is $15 a week over the four weeks. Extra costs come to $103 a week.

Count only the costs the deal causes. The rent and the manager's salary get paid either way.

Step 4: Find the break-even, then see how much it moves

Nobody knows in advance how many regulars will switch. So run the numbers at three rates:

For the base case: 96 × $2.21 = $212.16, plus $103 is $315.16, and $315.16 ÷ $7.04 = 44.77, so 45 added orders a week. Even in the low case, lunch orders have to grow 14% from people who wouldn't otherwise have come. That's the point of doing the math first.

If the shop could run the deal without the extra hour of help, the base case would drop to 33 added orders a week. Labor and capacity matter as much as the price.

Busy isn't the same as paying

Say the deal brings in 30 added orders a week at the base switching rate. The shop sells 126 combos a week and lunch looks busier. But 30 × $7.04 = $211.20 earned, minus $212.16 lost on switchers, minus $103 in extra costs, leaves the shop $103.96 a week worse off, or $415.84 over the four weeks.

Redemptions count switchers and new guests together. A high redemption count doesn't show the deal is working.

If the deal leaves nothing per order, stop

Do step 1 before anything else. If the deal price minus food, packaging and fees is negative, every added order makes the result worse, so more traffic can't fix it. If it's exactly zero, added orders don't make things worse, but they don't earn anything either. They can't cover money lost on switching regulars or the deal's extra costs, so as long as those leave a shortfall, there's no break-even number. In both cases, reprice the deal, change what's in it, or drop it. Check this again whenever a supplier raises the price of something in the bundle, and for each channel with its own fees.

The opposite can happen too. If most of your regulars buy a sandwich alone and the bundle adds items that cost you little, switching may cost you nothing or even leave you a little more. Count that gain against the extra costs, so you need only enough added orders to cover what's left. If the gain covers all of the extra costs, you don't need any added orders to break even. Check that against your real item mix before you count on it.

Check the rush, not just the average

At the base break-even, the shop needs an average of 71.25 orders per lunch service, a little over the 70 its current crew handles well. That's why the extra hour is in the plan. In the high case it's 75. Averages hide the rush. If the added orders all arrive between noon and 1, ticket times can slip even when the daily total looks fine, and slow service can cost you the regulars you're trying to keep. Track the busiest half hour, not just the total.

The worksheet

1. Days, hours and test dates: ____
2. Baseline orders a week for those days and hours without the deal, from several comparable weeks: ____
3. Deal price: $____; food and drink cost: $____; packaging: $____; fees as a share of the check: ____% (each channel separately)
4. Deal contribution = price − food − packaging − fees: $____. If it's zero or negative, stop here.
5. Usual orders for those hours: price, contribution and share of orders for each: ____
6. Lost contribution per switching order = the sum of each usual order's share × (its contribution − deal contribution): $____. It's negative if switching leaves you more.
7. Switching rate, low / base / high: ____% / ____% / ____%, so switching orders a week: ____ / ____ / ____
8. Extra costs a week: added labor hours × full employer cost per hour $____ + setup costs ÷ weeks in the test $____ + anything else $____ = $____
9. Break-even added orders a week = (switching orders × line 6 + line 8) ÷ line 4, rounded up. If switching orders × line 6 + line 8 is zero or less, write 0: ____ / ____ / ____
10. Capacity: orders per service the crew handles well: ____; baseline plus break-even orders per service: ____; busiest half hour: ____
11. Stop or reprice rule and review dates, written down before the deal starts: ____

Run it as a short test

Counting redemptions can't tell you who would have come anyway. Measure totals instead.

1. Pick the comparison first. Use the same days and hours from several recent weeks before the deal. Last year's same weeks can help if your menu, prices and hours were about the same.
2. Set it up the same everywhere. The POS, online ordering and any delivery app should all ring the combo at the same price, and the start and end dates should be on the sign.
3. Record every service. Total orders, net sales after discounts and before tax and tips, combos sold, sandwiches, chips and drinks sold, paid labor hours, and orders and ticket times in the busiest half hour.
4. Add up contribution each week. Net sales minus food, packaging and fees for those services. The shop's baseline is 240 orders × $9.25 average contribution = $2,220 a week. To break even, a test week needs $2,323: the baseline plus $103 in extra costs. At the base case, 45 added orders produce $2,324.64.
5. Look outside the deal hours. If Friday lunch drops when a Monday-to-Thursday deal starts, some of those "new" orders just moved. Count them as switchers.
6. Write down anything else that moved traffic. Weather, school calendars, local events, holidays, road work and a nearby opening or closing can all change a week's numbers.

A four-week test can't prove the deal caused the change. It can tell you whether the numbers moved enough to justify keeping it, and it can catch a losing deal early.

Write your stop rule down before day one. For example: if weekly lunch contribution after the extra costs is below the baseline in both of the first two full weeks, stop or reprice. If ticket times in the rush go past your standard on more than two services in a week, add help or limit the deal to fewer hours. Otherwise, end it on the date on the sign and decide with the full four weeks in front of you. Once guests get used to a $12 lunch, ending it can feel like a price increase, which is another reason to put the end date on the sign from the start.

What this check doesn't tell you

This covers one offer over one short period. It says nothing about whether the restaurant as a whole makes money. If the full week can't cover its bills, a deal that breaks even won't change that. Use the restaurant break-even calculator and the free P&L builder to check the whole operation.

New guests the deal brings in may come back later at full price. Count that only once you can see them coming back.

If you're deciding whether to stay open during a slow stretch at all, see should you close your restaurant during slow hours? For the opposite move, raising a price and working out how many sales you can afford to lose, see how much your burger price should go up when beef costs more. For a launch campaign aimed only at first-time customers, see get your first paying restaurant customers. To cost each item in the bundle, use the restaurant food cost calculator.

Limits

The sandwich shop and all of its prices, costs, order counts, switching rates, fees and capacity figures are fictional. They show the arithmetic, not typical costs or results. The Association's survey is a national read on consumers. Its public summary doesn't describe the sample or when the survey was fielded, and it doesn't predict how your guests will respond to a deal. We haven't tested this deal in a restaurant, and none of this predicts how many new guests a deal will bring in.
