Business Runway Calculator.

A Runway Calculator helps founders and small business ownersestimate how long their business can survive based on available cash, monthly expenses, and monthly income.

Your runway is the amount of time your business can keepoperating before it runs out of cash.

This is useful for understanding:

• how many months of survival your business has left
• whether expenses are too high
• whether revenue is covering enough of your costs
• when you may need funding, sales growth, or cost reduction
• how urgent your financial situation is
  

Let’s say your business has:

• $1,000,000 in available cash
• $350,000 in monthly expenses
• $150,000 in monthly revenue

Your monthly cash burn is:

$350,000 - $150,000 = $200,000

Your runway is:

$1,000,000 ÷ $200,000 = 5 months

This means your business has about 5 months before cash runs out, assuming income and expenses stay the same.
