Restaurant Opening Budget Calculator
Add up every line of capital you need to open — building the site, getting licensed, staffing before you trade, and funding the months before the restaurant pays for itself.
What this calculator adds up
Most restaurants that close in their first year do not close because the food was wrong. They close because the opening budget covered the cost of building a restaurant and not the cost of running one until it stands on its own. The fit-out completed, the equipment landed, the doors opened to a full room of friends and neighbours — and then payroll fell due in week nine against sales that had not yet reached plan.
So this calculator totals both halves of the number. The first half is capital works: everything that turns a shell, or a tired unit someone else gave up on, into a site that can trade. The second half is the cash that has to be sitting in the account on opening day, because a new restaurant consumes money before it produces any, and no supplier has ever agreed to wait until trade picks up.
Enter what you know and leave the rest blank. Early on, most operators have three or four firm figures — a builder's quote, an equipment list, the deposit the landlord is demanding — and a wide range on everything else. The point of totalling it now is not precision. It is finding out whether you are raising $180,000 or $420,000, because those are entirely different conversations with a bank, a landlord and anyone you are asking to invest.
The seven buckets of opening capital
Fit-out and construction
Builder, shopfitting, extraction and ventilation, gas and electrical supply, drainage, flooring, toilets, decoration. This is usually the largest single line and the one that moves the most between quote and final invoice, because the things that go wrong are hidden until the walls come down. Extraction and drainage in particular have a habit of turning an affordable unit into an expensive one after the lease is signed.
Kitchen equipment and smallwares
The cooking line, refrigeration, dishwash, prep benches and shelving — plus the smallwares almost nobody budgets properly. Pans, knives, gastros, containers, scales, thermometers and service crockery routinely add a five-figure sum on their own. Used equipment can halve this bucket, but only for items where failure is inconvenient rather than catastrophic; buying a second-hand dishwasher is a reasonable risk, buying second-hand refrigeration usually is not.
Furniture, fixtures and technology
Tables, chairs, banquettes, the bar, lighting, signage, and the entire technology stack: point of sale, tills, card terminals, network, booking system, cameras, music. Technology is the bucket that has quietly grown. Ten years ago it was a till; now it is a subscription-based POS, an online booking platform, a delivery tablet and the cabling to support all three.
Deposits and bonds
The rent deposit, rent in advance, and the security bonds that utilities and equipment financiers ask a business with no trading history to post. This money is not spent, but it is gone from your working capital for the length of the lease, which for budgeting purposes is the same thing. Landlords commonly ask for three to six months from a first-time operator.
Licences, permits and professional fees
Food business registration, liquor licence, planning and change-of-use applications, the architect, the lawyer who reads the lease, the accountant who sets up the company, and the insurance that has to be in force before a builder sets foot on site. Professional fees feel avoidable right up to the moment a lease clause costs you far more than the lawyer would have.
Pre-opening payroll and training
Wages from your first hire to opening day. A head chef typically starts six to eight weeks out, sous and managers two to four, the balance of the team one to two. On top sit training food, trial services, uniforms, menu printing and whatever marketing you do before anyone can actually buy anything. This bucket is pure outflow with zero revenue against it.
Opening inventory
The first full food order, beverage and wine stock, and the cleaning and paper consumables that arrive in quantities nobody expects. Wine is the trap here: a list of any depth ties up serious capital that then sits in a cellar for months. Opening with a shorter list and deepening it from trading cash is almost always the better decision.
Where opening budgets usually go wrong
| Budget line | How it usually goes wrong |
|---|---|
| Fit-out | Quoted before survey. Extraction, drainage and electrical capacity emerge once work starts. |
| Smallwares | Left off entirely, or estimated at a tenth of the real figure. It is a long, boring list. |
| Pre-opening payroll | Counted from opening day instead of from first hire, missing six to eight weeks of senior wages. |
| Opening stock | Priced as one delivery. In practice you restock two or three times before revenue stabilises. |
| Working capital | Set at one month, or omitted because the plan assumes the site trades to budget from week one. |
| Contingency | Cut to make the total fit the funding available, which does not make the overruns go away. |
| Opening delay | Rent, insurance and senior payroll run while the licence or the builder does not. |
Every line in that table fails in the same direction: the total is understated, never overstated. That is not bad arithmetic, it is optimism doing what optimism does. The correction is mechanical rather than attitudinal — price the lines you can, add a stated contingency, and refuse to reduce the contingency simply because the total came out uncomfortable.
Working capital is the line that sinks people
A new restaurant does not reach its steady-state sales on day one. It opens busy on curiosity, drops in weeks three to six as that fades, and then builds back on repeat custom and word of mouth. The climb to a normal week takes three to six months in most neighbourhood sites, longer if you opened into a quiet season. Throughout that period the fixed costs are already running at full rate.
Use your break-even calculator to find the sales level the site has to hit, then estimate honestly how many months it takes to get there. If your rent, payroll, utilities and everything else come to $68,000 a month and you expect four months of sub-break-even trading, you need roughly $272,000 of reserve — frequently more than the equipment bill, and almost always the line that gets trimmed first.
Three months is the practical minimum for any site. Six is what you want if the location is unproven, the concept is unfamiliar to the area, or the opening date depends on a licence or a landlord. Once trading, a rolling cash flow forecast tells you how fast the reserve is actually being consumed, which is the only figure that matters in month two.
Capital per seat as a sanity check
Dividing the total by seats produces one number you can compare against other projects, ask experienced operators about, and use to spot a budget that has drifted. Ranges vary enormously by market, by whether the unit was previously a restaurant, and by how much of the fit-out you are inheriting — but within your own city, people who have opened recently will tell you immediately whether your figure is plausible.
It also forces a useful question: does the room have enough seats to service the capital going into it? A high per-seat figure is not automatically wrong, but it has to be justified by either high average spend or high turnover. Model both with the seat turnover revenue calculator and the average check calculator before you accept a design that trades covers for comfort.
Turning the total into a decision
The number this calculator produces is not a target to raise. It is a test the project has to pass before you sign anything.
- Check the rent against plausible sales, not against the total. A deposit you can afford tells you nothing. Run the rent-to-sales ratio at a realistic revenue figure, because rent is the one cost you cannot renegotiate after opening.
- Price the menu before the fit-out is finalised. If the menu prices the market will bear cannot carry your intended prime cost, no amount of capital fixes it.
- Keep the contingency separate and visible. A contingency folded into line items stops being a contingency and becomes a budget to spend.
- Model a two-month opening delay. Add rent, insurance and senior payroll for those months and see whether the project still funds. Delays are the norm, not the exception.
- Decide in advance what gets cut. Name the items you will drop if the fit-out overruns by 20%, while you can still think clearly about it.
- Fund from cash and facility, not from suppliers. Stretching supplier terms to cover a shortfall damages the relationships you need most in month three.
If the total comes out higher than you can fund, that is the calculator working. A smaller site opened with a proper reserve beats a larger one opened on fumes, every time and in every market.
Frequently asked questions
How much does it cost to open a restaurant?
There is no single figure, because fit-out condition, size and market drive most of it. What is consistent is the structure: capital works, pre-opening costs, a working capital reserve and a contingency. Price your own four buckets rather than trusting an industry average that describes nobody's actual site.
How much working capital should I hold on opening day?
Three months of full operating costs is the minimum, six is safer. The reserve has to cover the gap between opening and reaching break-even, which typically takes three to six months. Sites that open with one month of reserve are betting the entire project on hitting plan immediately.
What contingency percentage should I use?
Ten to twenty per cent of the total, weighted towards twenty if the fit-out is extensive or the building is old. Anything involving extraction, drainage or structural work carries the most overrun risk, because the problems are invisible until the work begins.
Should I buy used kitchen equipment?
Selectively. Used is sensible for items where failure is inconvenient — benches, shelving, some cooking equipment. It is a poor trade on refrigeration and dishwash, where a breakdown stops service and costs more in lost trade and spoiled stock than the saving was worth.
Does the landlord contribution change the number?
Yes, materially. A fit-out contribution or rent-free period reduces the capital you raise, but read how it is paid. Contributions often arrive on completion, meaning you fund the work first and get reimbursed later, so the cash requirement is unchanged even if the final cost is not.
Is pre-opening payroll really that large?
It is usually larger than people expect. A head chef starting eight weeks out, managers at four, and the full team at one or two adds up quickly, and none of it has revenue against it. Counting payroll from opening day rather than from first hire is one of the most common budget errors.
What if the total is more than I can raise?
Reduce the scope, not the reserve. Fewer seats, a shorter menu, a smaller wine list or a unit that needs less structural work all lower the capital requirement honestly. Cutting the working capital reserve lowers it on paper only, and moves the risk to month three.
