A lot of business owners track revenue religiously and ignore everything else. Sales go up, they feel good. But revenue alone doesn't tell you if your business is actually worth more than it was six months ago. Owner's equity does.
Owner's equity is what's left in the business after you pay off everything you owe. If you sold every asset and cleared every debt today, the remaining cash would be your equity. That's it.
The formula:
Owner's Equity = Assets – Liabilities
A landscaping company with $80,000 in equipment and vehicles and $30,000 in outstanding loans has $50,000 in equity. A repair shop with a $600,000 garage, $50,000 in machinery, and $50,000 in inventory has $700,000 in assets. If the only liability is a $300,000 mortgage on the premises, equity sits at $400,000.
Simple math. But the interesting question is why that number goes up or down every single month. And also, what it's actually telling you.
What moves your equity
Four things push equity up or down, and they don't always move together.
Profit is the most sustainable driver. Every dollar of net income that stays in the business adds directly to equity. Owner contributions (injecting personal cash) also push equity up, but that's not growth. That's just a transfer.
The tricky one is "draws." When you pay yourself out of the business, equity drops. A business can post strong profits and still show flat or declining equity if the owner is pulling too much out. This is why you can feel busy and profitable while your business is quietly worth less.
The statement of owner's equity
Your balance sheet shows your equity at a single point in time. The statement of owner's equity shows how you got there, the movement between one period and the next.
It works like this:
Beginning equity + Net income + New contributions – Owner draws = Ending equity
Here's a straightforward example:
That's a $3,500 increase in one month. The business earned $8,500, the owner took $5,000, and equity grew by the difference.
Now change one variable: the owner draws $10,000 instead. Ending equity drops to $40,500, below where January started. The business still made money. The owner still paid themselves. But the business is worth less than it was 30 days ago.
This is the number most owners aren't watching.
Positive vs. negative equity
Positive equity means the business has more assets than debts. Negative equity means the opposite. In that case, liabilities exceed what the business owns.
Negative equity happens for a few reasons: a stretch of operating losses, owner draws that consistently exceed profits, or taking on significant debt to buy assets that don't hold their value. It's recoverable, but it needs a deliberate response: control costs, stop drawing, or bring in new capital.
Left unaddressed, negative equity makes it very hard to borrow money, since lenders look at equity to decide if there's anything backing the loan. It also signals that the business couldn't cover its debts if it had to.
Positive equity, especially rising e
quity, sends the opposite signal. Lenders see security. Potential buyers see a business building real value. You see proof that operations are actually working.
How this connects to your other statements
Owner's equity doesn't live in isolation. It ties directly to your income statement and balance sheet.
Your income statement tells you net profit for the period. That profit flows straight into equity on the balance sheet. The statement of owner’s equity is the bridge that explains the path, starting balance, what changed, and ending balance.
If you've ever wondered why your profit looks decent but your bank account feels thin, equity tracking can help answer it. Profit and cash flow are different. You can earn a profit on paper while cash is tied up in unpaid invoices or inventory. Equity captures the accumulated value of all of that, including assets that aren't cash.
What to actually do with this
Check your equity at the end of every month, not just at year-end when your accountant hands you a report.
The questions are worth asking: Is it higher or lower than last month? If it dropped, was that from a draw or a loss? If it was a draw, was that planned? If equity is growing, what's driving it: profit or just more money going in?
You don't need a finance degree to track this. The calculation is subtraction. Most accounting software calculates it automatically. The hard part is building the habit of looking at it and asking why it moved.
A business that's genuinely growing shows rising equity over time. Revenue can look healthy while equity stagnates or falls. The owners who catch problems early are usually the ones who watch both.
That's the number. Track it monthly. It'll tell you things your revenue figure won't.
