How to calculate your true net worth, including inventory

If you sell physical goods, your bank balance is not your business net worth. Inventory is an asset. Credit card balances, supplier payables, and short-term debt are liabilities. The gap between the two is the number that tells a more honest story.

Start with the balance sheet view

The simplest formula is assets minus liabilities equals net worth.

For inventory-led businesses, assets often include cash, bank balances, inventory on hand, receivables, prepaid expenses, and equipment. Liabilities include credit card balances, loans, outstanding bills, and taxes owed.

Why inventory changes the picture

Without inventory, many sellers think the business is weaker than it is because cash looks low after restocking. With inventory tracked, you can see that some of that cash simply moved into stock that can still generate margin.

The reverse is also true. If inventory is sitting too long, the balance sheet can look stronger than the business feels. This is why pairing valuation with turnover and margin matters.
