A Simple Table to See How Long Your Restaurant Can Survive
Cash flow is the real lifeline of a restaurant. Use one simple table to track cash reserves, daily burn, and survival runway before risk turns into crisis.
Restaurant owners rarely fail because they lose money for one day. They fail because they lose money for too long without realizing how close they are to the edge.
That is why cash runway matters more than intuition. A store can look busy and still be weeks away from a cash-flow problem.
Today, we will use one small table to answer three questions:
- How much cash do you actually have?
- How much do you burn every day?
- How many days can the business survive if revenue drops?
Why cash flow matters more than accounting profit
Profit is an accounting result. Cash flow is a survival reality.
You might show a profit on paper for the month, but if rent, payroll, suppliers, and utilities all hit at the same time, paper profit does not pay the bills. If the account balance is not there, operations break first.
In practice, many restaurants close not because the concept was impossible, but because they ran out of cash before they had time to adjust.
The cash runway table: only four numbers
This framework is intentionally simple.
| Item | Meaning | Example |
|---|---|---|
| Cash reserve | Money you can use immediately | 80,000 CNY |
| Monthly fixed cost | Rent + payroll + utilities + recurring overhead | 45,000 CNY |
| Daily fixed burn | Monthly fixed cost ÷ 30 | 1,500 CNY/day |
| Survival runway | Cash reserve ÷ daily fixed burn | 53 days |
That final number is your runway.
If revenue suddenly drops to zero, the runway tells you how many days the business can stay alive before cash runs out.
How to use it in real operations
Update this table every day or at least every week.
Once you can see runway clearly, your decision-making changes:
- If runway is under 30 days, the priority is survival and cash protection.
- If runway is 30 to 60 days, you still have room to adjust pricing, scheduling, or marketing.
- If runway is above 60 days, you can make calmer decisions and test improvements with less panic.
What owners usually get wrong
The most common mistake is tracking revenue but not daily burn.
Owners often know today's sales number, but they do not know:
- how much fixed cost is consumed every day,
- how much promotion spend is really helping,
- how many days of safety remain if traffic slows down.
That is exactly why a simple runway table is powerful. It removes guesswork.
Final takeaway
Do not wait until payroll gets tight to ask how much time is left.
Track your cash reserve, your daily fixed burn, and your survival runway now. If you can see the countdown early, you still have options. If you only look at revenue, you may notice the danger too late.
