Your business has vital signs — here's how to read them

You learned to take vital signs in your first weeks of clinical training. Blood pressure, heart rate, respiratory rate, oxygen saturation, temperature. Five numbers that told you — at a glance — whether a patient was stable or heading toward a crisis.

You got fast at it. Eventually it was automatic.  The vitals gave you a reliable starting point every time.

Your business works in much the same way.

Why revenue alone doesn't tell you enough

Most entrepreneurs track one number: how much came in this month. Revenue feels like progress, and sometimes it is — but it doesn't tell you if your business is actually healthy.

A business can bring in $8,000 a month and still be running toward trouble. Cash might be going out faster than it's coming in. Clients might be one-time buyers who never return. Costs might be eating most of what's left after direct expenses. None of that shows up in the revenue number alone.

Tracking only revenue is like recording a patient's height and weight and calling it a full assessment. It's data. It's just not the right data for figuring out what's actually going on.

The 6 business vital signs

Six metrics give you a clear, complete picture of your business health — quickly, without drowning in data:

1. Days cash on hand — how long your business can survive without new revenue coming in
2. Quick ratio — whether you can cover your immediate debts with what you have right now
3. Gross profit margin — how much of each dollar actually stays after your direct costs
4. Break-even point — the minimum you need to bring in each month just to cover all costs
5. Customer acquisition cost — what it actually costs you to bring in each new client
6. Customer retention rate — the percentage of clients who keep coming back

Each one tells a different story. Together, they give you a full picture — the same way a complete set of vitals gives you a clinical baseline to work from.

Over the next several posts, we'll walk through each one: what it means, how to calculate it in about five minutes, and what to do when the number looks off.
