Full-Service Casual Restaurant SBA 7(a) buy-vs-build cash-flow calculator
Stress-test building a full-service casual restaurant from scratch against acquiring an existing cash-flowing resale using SBA 7(a) financing. Adjust startup CapEx, revenue, owner SDE margin, acquisition multiple, and loan terms to compare Year-1 ramp-up cash flow, Debt Service Coverage Ratio (DSCR), and 3-year cumulative owner take-home.
SBA 7(a) underwriting & payback takeaway:
At $1,850,000 revenue and 12% SDE margin ($222,000/yr pre-debt cash flow), buying an existing full-service casual restaurant at 2.6× SDE ($577,200) generates $142,558/yr from Day 1 (2.79× DSCR), giving an immediate $270,557 Year-1 cash-flow advantage over building from scratch during a 18-month ramp-up. Once ramped in Year 2+, building from scratch ($930,000 CapEx) nets $94,001/yr (1.73× DSCR). By comparison, a 4% gross-sales franchise royalty on $1,850,000 revenue deducts $74,000/yr directly from owner cash flow.
Frequently asked questions about starting or buying a full-service casual restaurant
How much does it cost to start a full-service casual restaurant?
Starting an independent full-service casual restaurant typically requires $350,000–$1,500,000 (2,800–5,500 sq ft dining room + commercial kitchen; second-generation restaurant space reduces hood/grease-trap CapEx by 30%–45%). The largest line-item startup expenses are Dining Room Buildout, HVAC, Restrooms & Leasehold Improvements ($110,000–$600,000), Commercial Kitchen, Type-1 Hood, Walk-In Cooler & Cooking Line ($120,000–$420,000), Working Capital & Pre-Opening Payroll (3–6 Months) ($70,000–$235,000). Founders should budget for both initial buildout/equipment CapEx and 12–24 months of working capital runway.
How much do full-service casual restaurant owners make and what is a healthy profit margin?
Established full-service casual restaurant operators generate $900,000–$2,800,000 in annual gross revenue (Annual gross food and beverage sales across lunch/dinner dayparts) with an owner cash flow of 8%–15% SDE margin (Prime cost (COGS + total labor) must stay below 60%–65% of gross sales). Key operating ratios include Food & Beverage COGS: 28%–34% of revenue; Total Labor & Payroll Taxes: 30%–35% of revenue; Occupancy (Base Rent + NNN/CAM): 6%–10% of revenue. Remember that gross revenue is top-line sales before payroll, COGS, and occupancy—not net owner take-home pay.
How is a full-service casual restaurant valued when buying or selling an existing business?
Operating full-service casual restaurant resales typically trade at 2.0x–3.2x SDE (Higher for transferable liquor licenses and favorable long-term leases), translating to typical acquisition prices of 2.0x–3.2x SDE ($144,000–$1,344,000). Key buyer due-diligence priorities: Verify Prime Cost (Food/Beverage COGS + All-In Labor) is under 65% of gross sales. Inspect Type-1 exhaust hood, grease trap capacity, walk-in compressors, and HVAC units.
Is it better to start an independent full-service casual restaurant or buy a franchise?
An independent full-service casual restaurant costs $350,000–$1,500,000 to launch and pays 0% ongoing royalties, whereas comparable franchise systems (Applebee’s, Denny’s, Chili’s, IHOP) require $245,000–$5,822,933 in disclosed Item 7 opening investment plus 4%–6% of Gross Sales + 2%–3% marketing. Franchising provides brand playbooks and vendor programs, while independent ownership preserves full margin control and exit flexibility.
