Building Your Restaurant's Financial Projections

Restaurant financial projections are a month-by-month forecast of sales, costs, and cash for your first one to three years, built from stated assumptions rather than a target you'd like to hit. Build the sales line from covers - seats times turns times average check times days open - then apply realistic cost percentages, then check whether cash ever goes negative. Lenders don't reject projections for being modest; they reject them for having no visible arithmetic.

Build sales from the bottom up

Never start with a revenue goal. Start with capacity.

Daily sales = seats x turns per day x average check

An 80-seat dining room turning 1.8 times at a $32 average check does about $4,600 a day. Six days a week is roughly $27,600 weekly, or about $1.44M annually at full stride. Now discount it honestly:

Layer in seasonality for your market and split revenue by channel - dine-in, takeout, delivery, catering - because each has different costs. Our guide on how to forecast restaurant revenue covers refining this once you have real data.

Apply cost percentages you can defend

Model labor as a schedule, not a percentage. Count the actual positions on the floor by daypart at your projected volume, multiply by wages, and add 12-15% for payroll taxes and workers' comp. That's how you find out your Tuesday lunch doesn't support three servers. The math in how to calculate labor cost percentage is the same one lenders will run.

Projections built from a target work backwards to justify a number. Projections built from covers, wages, and a rent check tell you whether the business works at all. Only the second kind survives a lender's questions.

Model cash, not just profit

Profitable restaurants close because they run out of cash. Build a separate monthly cash schedule that includes items the P&L doesn't: loan principal payments, owner draws, sales tax remittance, deposits, prepaid insurance, and the working capital you burn in slow months.

Keep three to six months of operating expenses as an opening cash reserve. If your model shows cash dipping below zero in month four, you don't have a bad projection - you have a funding gap to fix before you open. See cash flow management for restaurants and how to improve cash reserves.

Find your break-even and pressure-test it

Break-even sales = fixed costs / (1 - variable cost %). If fixed costs are $38,000 a month and variable costs run 68% of sales, you need about $118,750 a month to break even - roughly $4,000 a day on a 30-day month. Compare that to your capacity math. If break-even requires 95% of your realistic capacity, the model is too tight to survive a bad quarter. Break-even analysis walks through the full calculation.

Then run three cases - conservative, base, and optimistic - by flexing average check and turns. Show all three. Presenting only the optimistic case is the fastest way to lose a lender's confidence.

Document your assumptions

Attach a one-page assumptions sheet to your model: seat count, turns, check average, days and hours open, wage rates by position, rent and CAM, food cost by category, and marketing spend. Every number in the projection should trace back to a line on that page. This is what turns a spreadsheet into a document a bank can underwrite, and it's the core of your restaurant business plan.

Plan for how you'll track actuals

Projections are worthless the moment you open unless you compare them to reality every month. Set up your chart of accounts to mirror your projection line items so variance is a subtraction, not a research project. Daily sales, category mix, and labor percentage should come straight out of your POS - an all-in-one system like Cobblestone POS reports sales, labor, and item-level margin without a monthly fee, which keeps your first-year variance review to about an hour a month instead of a weekend.

Build it from covers, defend every percentage, and check the cash line. Do that and your projections become a management tool, not a financing formality.
