Running a restaurant is full of uncertainty, from changing guest patterns to food costs and supply shifts. Yet waste remains a huge problem. Over 46% of all food produced in Canada ends up in the waste stream, and 41% of that is avoidable.
When you predict demand wisely, you minimize over-stocking, reduce spoilage, and keep costs under control. This guide explains how to approach restaurant demand planning in a manageable way so you can stay prepared, without overburdening your kitchen or your budget.
What you need to know:
Restaurant demand planning is the process of predicting how much product, labor, and preparation your operation will need in order to meet expected guest demand without overspending or running short.
It connects sales patterns, inventory needs, and operational realities so you can make informed decisions rather than react at the last minute.
Here are the core components that shape effective restaurant demand planning:
When done well, demand planning aligns your kitchen, staff, purchasing, and guest experience into one coordinated rhythm. The next step is understanding what actually influences demand.

Recognizing external influences can help you forecast more accurately and avoid costly overproduction or stockouts. These are the major factors that affect restaurant demand:
Once you understand what drives demand, the next step is turning those insights into a clear, usable forecast. Let’s walk through how to build a reliable demand prediction that supports both kitchen and front-of-house operations.

A reliable demand forecast blends numbers, patterns, and real-world context. It helps you anticipate guest volume, reduce waste, schedule smarter, and ensure you always have the right amount of inventory and labor on hand.
These steps can turn daily operations from reactive guesswork into predictable, manageable outcomes:
As W. Edwards Deming famously said, “Without data, you’re just another person with an opinion.”
Historical sales form the backbone of every forecast. You look at past performance to understand normal volume, slow periods, peak days, and menu item velocity. This gives you a baseline that reflects how your restaurant naturally behaves.
Formula:
Average Daily Sales = Total Sales for Period / Number of Days
Beyond averages, study:
iOrders supports this by automatically recording every order (dine-in, pickup, and delivery) into a single dashboard. It shows item-level performance, hourly order patterns, repeat-customer behavior, and historical trends you can filter by date, channel, or menu category.
Different times of day carry distinct operational rhythms. Breakfast, lunch, dinner, late-night, and weekend traffic often follow consistent patterns. Recognizing these cycles helps you refine your forecast beyond broad daily averages.
Look for:
This step ensures prep and staffing align with how guests actually visit your restaurant.
External factors can reshape demand instantly, even when internal patterns remain stable. Weather, local events, promotions, and holidays are all powerful variables that must be included in any credible forecast.
Adjustment Formula:
Adjusted Forecast = Baseline Forecast x (1 + Estimated Impact Percentage)
External factors can be in the form of:
Example calculation:
If the baseline forecast is 200 orders and hot weather is expected to increase demand by 15%, then
Adjusted Forecast = 200 x (1 + 0.15) = 230 orders
Including these variables makes your forecast far more realistic and reduces the risk of costly miscalculations.
A strong forecast predicts not only total covers but what guests will order. Item-level forecasting helps you plan prep quantities, batch cooking, and purchasing decisions with much greater accuracy.
Formula:
Item Forecast = Total Forecast x Item Sales Percentage
This enables you to:
By predicting demand for each menu item, you avoid overproduction, cut waste, and maintain smoother, more consistent service during peak periods.
Once item-level demand is clear, convert those projections into ingredient requirements. This prevents overstocking, avoids spoilage, and protects your margins.
Formula:
Ingredient Requirement = Item Forecast x Ingredient Usage per Item
This approach supports:
Accurate inventory planning directly reduces avoidable waste and prevents unnecessary purchasing, making it one of the most reliable ways to keep food costs under control.
Labor decisions should follow forecasted traffic patterns. Forecasting helps you assign the right number of hours, roles, and skill sets to each shift.
Formula Example:
Labor Hours Needed = Forecasted Guests / Guests Served per Labor Hour
This helps you:
POS reporting, delivery trends, reservation patterns, customer behavior analytics, and weather-tracking tools improve forecasting accuracy. When these systems reinforce each other, you spot patterns earlier and respond more confidently.
iOrders streams real-time order and item-level data into your dashboard. Your team can see what sells when, adjust prep lists and staffing, and order inventory just in time to cut down waste and smooth operations. See how it works in a free demo.
Inventory planning directly affects food cost, freshness, and guest satisfaction. When your purchasing aligns with your forecast, you avoid over-ordering, prevent spoilage, and ensure you always have enough on hand to meet demand.
The goal is simple: carry the right amount of stock. Not too much, not too little.
These are key techniques that keep inventory efficient and reliable:
Aligning inventory with demand is only half the equation. The next step is ensuring your workforce follows the same rhythm through smarter staffing and scheduling practices.

Labor is one of the highest controllable costs in any restaurant, which makes accurate scheduling essential. Instead of guessing how many people you need, your schedule becomes a reflection of predictable guest patterns.
These are a few effective approaches to align staffing with demand:
Restaurant demand planning helps forecast what, when, and how much to prepare so guests enjoy consistent quality and service. Before refining your process further, you need to know the most common demand planning pitfalls and how to avoid them.
