How to use this calculator

Enter monthly cash inflow and the major cash outflows. Add your current cash reserve to estimate how many months the restaurant can survive at the current expense level.

What the result means

Positive cash flow means the business is producing usable cash after bills. Negative cash flow means the restaurant may still appear busy while becoming financially fragile.

Net Cash Flow = Cash Inflow - Total Cash Outflow. Cash Flow Margin = Net Cash Flow ÷ Cash Inflow × 100. Runway = Cash Reserve ÷ Monthly Outflow.

Cash flow is different from accounting profit. Debt payments, timing of bills, and inventory purchases can create cash pressure even when profit looks acceptable.

Example calculation

If cash inflow is $65,000 and total outflow is $56,500, monthly cash flow is $8,500 and the cash flow margin is 13.08%.

Tips for better results

  • Keep at least one to three months of expenses as cash reserve.
  • Review debt payments separately from operating costs.
  • Watch fixed costs first when cash flow turns negative.

FAQ

A cash flow margin above 10% is generally stronger than a thin margin close to zero.

How many months of runway does a restaurant need?

Restaurants with volatile sales should aim for more runway, while stable restaurants may operate safely with a smaller reserve.

Why is my restaurant profitable but short on cash?

Cash can be tied up in inventory, debt payments, payroll timing, taxes, or delayed receipts.

How do I improve restaurant cash flow?

Reduce fixed costs, improve inventory purchasing, negotiate payment terms, and raise margin on high-volume menu items.
