Every cafe that fails looked fine in the founder's head. The coffee was good, the fit out was right, the location felt busy. What was missing was a model that turned the plan into numbers and asked whether they added up. Financial modelling is unglamorous. It's also what separates a cafe that trades its way to profit from one that runs out of cash and can't work out where it went.
A cafe financial model is built from five pieces. Get each one realistic and you can trust the numbers before you commit to a lease.
What a cafe financial model actually is
A financial model is your cafe as numbers over time. At its simplest it takes what you expect to earn, subtracts what you expect to spend, and shows what's left, month by month, on assumptions you can change and test.
The profit figure at the bottom matters less than what the model lets you try. Change the rent and see what happens. Drop the average spend by a dollar and watch the margin move. Add a staff member and check whether the takings still cover it. A model lets you make your expensive mistakes for free.
A model is only as good as its assumptions. The maths is easy. The hard part is being honest about how busy you'll really be and what things will really cost, instead of working backwards from the answer you want.
Build revenue from covers and average spend
Revenue is where optimistic models go wrong, because it's tempting to start with a number that feels right. Build it from the ground up instead. Estimate your covers, the number of customers, for each part of the day, then multiply by a realistic average spend.
| Daypart | Covers | Average spend | Revenue |
| Morning | 90 | $9 | $810 |
| Midday | 70 | $18 | $1,260 |
| Afternoon | 40 | $7 | $280 |
| Daily total | 200 | $2,350 |
Add that up across a realistic week, adjusted for quieter and busier days, and you have a monthly revenue figure you can defend. It makes you face how busy you really expect to be, and a lender will trust it far more than a round number that came from nowhere.
Cost of goods from a properly costed menu
Cost of goods is what your sales cost you in ingredients. It should come from a real costed menu, not a percentage pulled from an article. Cost each dish and drink on yielded weight and your cost of goods matches what you actually sell.
This is where the model meets the kitchen. Cost the menu properly and the model inherits accurate numbers. Don't, and every projection after it is built on sand. Our guides on how to cost a cafe menu and the cafe food cost calculator cover the method, and a pre-costed recipe library gives you a costed starting point to model from.
Labour, rostered to your real hours
Labour is one of the two largest costs a cafe carries, and it's easy to understate if you think in headline wages instead of real rosters. Model it from the shifts you'll actually run across your opening hours, and include the parts people forget.
- Penalty rates on weekends and public holidays under the relevant hospitality award.
- Superannuation and on costs on top of the base wage.
- Your own time, if you're working in the cafe, valued honestly and not treated as free.
Rostered to demand, total labour including on costs should sit around 28 to 30% of turnover for a healthy cafe. Build it from real shifts, not a flat percentage, or the number is a pleasant fiction.
Overheads, the costs that are easy to underestimate
Overheads are the running costs beyond stock and wages, and there are more of them than most new owners list. Rent is the obvious one, but a real cafe carries dozens of smaller costs that add up to a real share of turnover.
Rent and outgoings, utilities, insurance, merchant and payment fees, waste and cleaning, repairs and maintenance, marketing, accounting, software, licences, and loan repayments or finance costs if you borrowed to open: they all belong in the model. Leave them out and a plan that looked profitable turns thin once you're trading. Our guide on cafe overheads has the full list to work through.
A model with only rent, wages and stock in it will always look healthier than the cafe will be. The realism is in the long tail of smaller overheads, so list them out properly. Don't round them into one vague number.
Cash flow: the number that keeps the doors open
Profit and cash are different things, and mixing them up closes cafes. Profit is what's left after costs over a period. Cash flow is whether the money is in the account when rent, wages and suppliers need paying. A cafe can be profitable on paper and still fail because the cash arrived too late.
New cafes are most exposed early, when takings are still building and the bills land in full from day one. A month by month cash flow shows the size of that gap and how much working capital you need to trade through it. It's the most underestimated number in a first cafe plan, and finding it early is half the reason to build a model.
Pressure test the model against reality
Once the pieces are in, don't just read the profit line and relax. Test the model against independent reference points and against your own worst cases.
Check your cost ratios against the ATO cafe benchmarks for your turnover band. If cost of goods or total expenses sit well outside the published ranges, or labour sits outside the industry guideline, an assumption is probably too optimistic. Then push the model down. What happens if covers come in 20% below plan, or rent is higher, or the slow start lasts twice as long? If the model survives a hard look, you can act on it. If it only works on the best case, that's your answer.
HospoSure builds the whole model for you: revenue from covers and average spend, cost of goods from a costed menu, labour rostered to your hours, over 40 common overheads, and cash flow month by month. Change an assumption and every number updates. Then export bank ready projections without wrestling a spreadsheet.

An owner who models their cafe well:
- Builds revenue from covers and average spend, not a hopeful headline figure.
- Takes cost of goods from a costed menu, so it matches what they actually sell.
- Models labour from real rosters, including penalty rates and on costs.
- Lists overheads in full, including the long tail of smaller costs.
- Projects cash flow month by month, to size the working capital they need.
- Pressure tests against benchmarks and against their own worst case.
Build the pieces honestly, tie them together in cash flow, test them hard, and you'll walk into the lease knowing the numbers instead of hoping. To put the model in context, our cafe business plan template for Australia shows how it fits the whole plan.
