A state where a company's cash inflows exceed its outflows — more money is coming in than going out each month.

What is Cash Flow Positive?

Being cash flow positive means your business generates more cash than it spends in a given period. For startups, this is a major milestone — it means you no longer depend on external funding to survive.

Cash flow positive is different from profitability in accounting terms, but for most startups the distinction is minor. What matters is that your bank account is growing, not shrinking.

Reaching cash flow positive doesn't mean you should stop watching your finances. Many companies oscillate around break-even, and a single large expense or lost customer can flip you back to negative.

Why it matters

Cash flow positive is the ultimate runway extender — your runway becomes infinite because you're no longer burning through reserves. You can grow at your own pace without the pressure of a countdown timer.

For fundraising, being cash flow positive transforms the dynamic. You're raising because you want to grow faster, not because you need to survive. That difference gives you dramatically better terms and more leverage.

Formula

Cash Flow Positive when: Monthly Revenue > Monthly Expenses (sustained)

Example

Your monthly expenses are $80,000 and your MRR is $85,000. You're cash flow positive by $5,000/month. Your bank balance grows by roughly $5,000 each month instead of shrinking.
