How to Build a 12-Month Restaurant Forecast: A Complete Guide for Operators
A strong 12-month forecast is the difference between running your restaurant in reaction mode and running it with confidence, strategy, and control.
Without a forecast, operators end up guessing about:
How much cash they’ll have in slow months
Whether new pricing will strengthen or hurt margins
When to hire more staff
When to open a second location
How vendor inflation will hit their COGS
How delivery growth affects profitability
Whether they can cover big expenses like repairs or equipment
With a proper forecast, you see problems months before they hit — and you make decisions proactively, not defensively.
Here’s how top restaurant operators build a clear, usable, accurate 12-month forecast.
1. Start With a Sales Projection Built on Reality
The first building block of a forecast is projected monthly revenue. This isn’t guesswork — it’s informed by data.
Use these inputs for accurate monthly sales projections:
Last 12–24 months of actual sales
Day-of-week patterns (example: Saturdays = 19% of weekly revenue)
Seasonality trends in your market
Local events and tourism months
Weather patterns (patio season = major shift)
Any expected catering or event growth
Delivery channel trends
Pricing changes or menu updates
Industry benchmarks

Example Sales Projection Outline:
January: Slightly down due to post-holiday slowdown
February: Normalization and Valentine’s bump
March–May: Seasonal strength
June–August: Patio season and tourism uplift
September: Leveling out
October–December: Strongest quarter of the year
2. Build a Sales Mix Forecast (Critical for COGS & Labor Accuracy)
A restaurant’s profitability isn’t based only on revenue — it’s based on where that revenue comes from.
Each sales channel carries different margins.
Forecast sales mix across:
Dine-in
Takeout
Delivery
Catering
Alcohol
Retail / merch
Events
Example Mix:
58% Food
24% Alcohol
12% Delivery
6% Catering
This mix matters because alcohol has lower COGS, delivery has higher fees, and catering often has better margins.
3. Forecast Cost of Goods Sold (COGS) Based on Price Trends + Mix
COGS forecasting is where most operators go wrong. They simply apply last year’s percentage — but that doesn’t reflect:
Vendor inflation
Seasonal ingredient swings
Menu engineering changes
Vendor price creep
New delivery packaging demands
Recipe cost changes
Shrink/waste improvements
How to create a more accurate COGS forecast:
Use xtraCHEF or MarginEdge to examine last 3–6 months of ingredient costs
Apply reasonable inflation assumptions (3–8% depending on category)
Forecast food, beverage, and alcohol COGS separately
Account for packaging and delivery-related COGS
Bake in expected vendor contract changes
Adjust based on projected sales mix
Forecasted COGS:
Food COGS: 29–33% depending on month
Alcohol COGS: 20–24%
Beverage COGS: 18–23%
Packaging COGS: 1.5–3% (delivery-heavy periods)

4. Forecast Labor with a Position-by-Position, Demand-Based Model
Labor is the second half of prime cost — and it's the most controllable and predictable when modeled correctly.
Labor forecast must include:
FOH hourly labor
BOH hourly labor
Manager salaries
Overtime buffer
Payroll taxes (FICA, SUTA, FUTA)
Benefits
PTO accruals
Holiday staffing
Seasonal changes
Turnover replacement costs
Forecast labor based on:
Sales projections (labor as % of revenue)
Covers per labor hour
Seasonal staffing needs
Historical overtime patterns
Delivery volume
Labor Outline:
FOH labor: 11–14%
BOH labor: 12–17%
Management salaries: 7–9%
Payroll taxes + benefits: 3–5%
OT cushion: +1% in seasonal periods

5. Forecast Operating Expenses (OPEX) with Inflation & Seasonality Factored In
Operating expenses should be forecasted month by month — not simply averaged.
Include:
Rent & CAM
Utilities (with seasonal adjustments)
Repairs & maintenance
Equipment leases
Waste services
Laundry/linen
Insurance
Subscriptions & software
Marketing spend
HR/payroll services
Admin supplies
Inflation-adjust strategic categories:
Utilities: +5–8% annually
Insurance: +5–12%
Repairs: variable, but usually trending upward
Use last year’s monthly pattern as your template.
6. Add Capital Expenditures (CapEx) Into the Forecast
This is where operators get surprised — because CapEx is usually unpredictable and devastating when unplanned.
Common restaurant CapEx needs:
Refrigeration replacement
HVAC repairs or replacements
Kitchen equipment (ovens, fryers, dish machines)
Dining room furniture
Patio expansions
Tech systems upgrades
Flooring or bathroom remodels
CapEx Planning:
Assign each major expense to a specific month
Give each item a “priority level”
Build a cash reserve buffer around those months

7. Build a Debt, Cash Flow, and Liquidity Plan
Even profitable restaurants can run out of cash without a forecast.
Add these into your 12-month plan:
Loan principal & interest payments
Line of credit usage
Quarterly tax payments
Credit card fees
Sales tax remittance schedule
Planned maintenance reserve
Cash-on-hand target
Seasonal cash dips (summer vs winter patterns)
Vendor payment cycles
Key question to answer:
Do we ever hit negative cash during the year?
If yes → fix by adjusting pricing, scheduling, CapEx timing, or vendor terms.
8. Summarize the Forecast Into a Simple, Owner-Ready View
A great forecast gives you one page with:
Monthly revenue
COGS %
Labor %
Prime cost %
Net profit before debt
Ending cash balance
If owners can read it in under 30 seconds → it’s good.
If it requires heavy explanation → it needs cleanup.
9. Review Your Forecast Monthly and Reforecast Quarterly
Forecasts are living documents.
Monthly:
Compare actual vs. forecast
Update future months accordingly
Reevaluate COGS trends
Adjust labor for real productivity
Review vendor pricing
Account for new menu changes
Quarterly:
Reforecast the full year
Update major assumptions
Add actual inflation rates
Shift CapEx timing
Update sales mix expectations
