Build a restaurant sales forecast from lunch and dinner orders, average checks and trading days. Compare slow and discounted scenarios and capacity.

A restaurant sales forecast starts with the number of orders your location can attract and serve, not last year's revenue multiplied by a growth percentage. Forecast lunch, dinner and delivery separately because their checks and costs differ. Then test the result against seats, table turns, kitchen throughput and staff coverage. A revenue target that needs more orders than a Friday rush can process is not a usable forecast.

Quick answer: Monthly sales = sum of each daypart’s expected orders × average check × trading days. If lunch serves 45 orders at $18 and dinner 75 at $32 over 26 comparable days, daily sales are $3,210 and monthly sales are $83,460. This arithmetic does not prove demand; check actual daypart counts and the busiest ninety minutes before trusting it.

Build the forecast from observable units

For each daypart, record potential traffic, realistic conversion, available seats or pickup slots and average spend excluding sales tax. Lunch at 45 orders × $18 equals $810 per day. Dinner at 75 × $32 equals $2,400. Over 26 identical illustrative trading days, ($810 + $2,400) × 26 = $83,460 monthly sales.

Now attach cost to those orders. If lunch needs $7 and dinner $12 in variable food, packaging, fees and incremental labor, daily variable cost is 45 × $7 + 75 × $12 = $1,215. Over 26 days it is $31,590. Contribution is $51,870. If guaranteed payroll, rent, owner pay and other fixed costs total $42,000, the illustrated operating result is $9,870 before tax and financing cash flow.

Replace identical-day arithmetic with a real calendar

Most restaurants do not sell the same number every day. Separate Monday through Thursday from Friday through Sunday, holidays, event days and known closures. Log actual transactions, channel and average check by date. If a restaurant opens 22 days after a late inspection, a forecast using 26 days overstates the first month's sales by four trading days.

Capacity adds a ceiling. Forty dining seats turned once at lunch allow at most 40 seated guests in that service unless takeaway adds separate kitchen output. If your target is 45 dine-in lunch orders, either turn seats, increase seats, take orders to go or lower the projection. Measure the kitchen's bottleneck, not just the room's theoretical seats. The SBA break-even explanation explains how volume ties to break-even; a forecast should be checked against that target.

Three monthly sales and contribution cases

Base: 45 lunch orders at $18 and 75 dinner orders at $32 yield $3,210 daily sales and $83,460 over 26 days. Daily variable cost of $1,215 yields $51,870 monthly contribution and $9,870 after $42,000 fixed costs.

Weaker foot traffic: 35 lunches × $18 plus 65 dinners × $32 = $2,710 daily sales, or $70,460 monthly. Variable cost is 35 × $7 plus 65 × $12 = $1,025 daily, or $26,650 monthly. Contribution is $43,810, leaving $1,810 after fixed costs.

Dinner discount: retain 45 lunch and 75 dinner orders but cut dinner's average check to $28. Daily sales become $810 + $2,100 = $2,910; monthly sales $75,660. If unit costs stay the same, monthly contribution is $44,070 and operating result is $2,070. A lower check may attract more orders, but this case assumes no increase; model evidence for any claimed lift.

What could move the forecast?

Guest mix and ticket can change independently. A drinks promotion may lift transaction count and lower blended spend. Third-party delivery can create orders in quiet hours but take commission and packaging cost. Weather, tourism, nearby office occupancy and school holidays affect particular days; record which factors are measured rather than apply vague seasonality percentages.

When you use a promotion, work backward from the extra orders required to replace lost contribution. If an average ticket falls by $4 while costs are unchanged, each discounted dinner contributes $4 less; 75 such orders lose $300 contribution per day in the example. Test staffing and kitchen capacity for the extra orders you hope to gain.

How to run your own numbers

Project each service period and channel, then calculate a realistic weighted average ticket and variable cost. Use the combined result to test how many orders cover fixed costs and whether the staff and kitchen can serve them.

Enter your own average ticket, variable cost, monthly fixed costs, owner pay and operating capacity in the free restaurant break-even calculator. It is a planning model, not a forecast of customer demand.

Common forecast mistakes

Using maximum seats as daily sales. Account for demand and actual table turns. Applying one ticket to dine-in and delivery. Keep fees and mix visible. Forgetting closures. A month with fewer trading days changes required orders per day. Forecasting only sales. Add per-order costs before evaluating whether the plan works. Assuming promotions produce enough extra orders. Measure conversion and check contribution after the discount.

Takeaways

• Forecast orders by daypart, check and trading day.
• Check the forecast against peak kitchen and seating capacity.
• Model order count and ticket separately.
• Recalculate contribution when channel mix or discounts change.

FAQs

How do I forecast restaurant monthly sales?

Estimate orders and average check for each daypart or channel, multiply by the days it operates, then add the results. Compare with actual transaction history and capacity.

What if I have no sales history?

Use observations of the location, comparable traffic and a conservative conversion assumption. Make the assumption explicit and update it once actual orders arrive.

Should I forecast food and drinks separately?

Yes when their prices and variable costs differ enough to move the result. A blended ticket can work for a quick first pass if its assumed mix is documented.

Do delivery orders count toward the forecast?

Yes, but track them separately if commission, packaging or kitchen timing changes their contribution.

Can I forecast the same sales every day?

Use a simple identical-day illustration to understand the arithmetic, then replace it with weekday, weekend and seasonal data for decisions.

What is the connection between forecast and break-even?

The forecast estimates achievable sales; break-even defines the sales required by your costs. Comparing them reveals whether the planned operation can meet its obligations.
