Opening a restaurant almost always costs more than first-timers expect and the ones that run out of money usually didn’t overspend on the build-out, they just forgot to fund the months before profit arrives. This free restaurant opening calculator gives you a realistic total: not just what it takes to get the doors open, but what it takes to keep them open until the business stands on its own.
Enter your one-time costs, add a contingency buffer, and set how many months of operating reserve you want in the bank, and you’ll see your total cash to open, how it breaks down, and your cost per square foot. It’s the number to know before you sign a lease.
Unlock your total cash-to-open estimate, reserve, and cost breakdown.
It varies enormously, a small counter-service spot might open for under $150,000, while a full-service restaurant with a significant build-out can run past $1 million. The biggest swing factors are whether you’re building from a raw space or taking over an existing restaurant, your location’s rent and market, kitchen equipment, and how much reserve you keep. This calculator gives you a planning baseline from your own numbers rather than a generic average.
Group them into one-time and ongoing. One-time costs include leasehold improvements and build-out, kitchen equipment, furniture and fixtures, POS and technology, signage, licenses and permits, initial inventory, pre-opening marketing, professional fees, and your security deposit. Then, separately, you need an operating reserve, payroll, and expenses for the first several months before revenue catches up.
It’s the cash cushion that keeps you running before the restaurant is profitable. New restaurants commonly take six months or more to reach break-even, and payroll, rent, and food orders don’t wait. Underfunding this reserve is one of the most common reasons new restaurants close despite a strong concept. This calculator treats it as a core part of your opening budget, not an afterthought.
Build-outs almost always uncover surprises such as permit delays, code upgrades, equipment that costs more than quoted. A contingency of 10% to 20% of your one-time costs is a sensible buffer; older buildings and heavy renovations push you toward the higher end. It’s money you hope not to spend, but not having it is how projects stall halfway through.
A common rule of thumb is three to six months of full operating expenses, on top of your build-out and one-time costs. If your monthly operating cost is $45,000 and you plan for three months, that’s $135,000 in reserve alone. More conservative operators, or those in expensive markets, aim for six months. Set the months in the calculator to match your risk tolerance and how quickly you expect to build sales.
