Plenty of small business owners can talk for an hour about their vision and then go quiet when you ask them a basic number about their own company. They know the brand, the story, and the customers by name, but the figures that decide whether the business survives stay fuzzy. That gap is dangerous, because feelings about a business and the facts of a business are often two different things. You can feel busy and be losing money. You can feel slow and be quietly profitable. The only way to know which one is real is to track a short list of numbers and check them often enough that they stop scaring you. Here are six worth knowing cold, the way you know your own phone number.

The first is your monthly cash position, meaning the actual money you have on hand right now. Profit on paper and cash in the account are not the same thing, and businesses with strong sales still go under because they run out of cash at the wrong moment. You should be able to say, without opening an app, roughly how much is in the account and how long it would last if revenue stopped tomorrow. That second figure is your runway, and it is the difference between making calm decisions and panicked ones. An owner who knows they have four months of cushion negotiates differently than one who is secretly two weeks from empty. Watch this number weekly, not yearly, because cash moves fast and surprises are almost always bad ones.

The second is your gross margin, which is what is left from a sale after the direct cost of delivering it. If you sell something for one hundred dollars and it costs you forty to make or provide, your gross margin is sixty percent. This number tells you how much each sale actually contributes before rent, software, and salaries get involved. Owners who do not know their margin often price by gut and end up working hard on products that barely earn anything. When you know the margin on each thing you sell, you can push the profitable offers and quietly retire the ones that drain you. It is one of the fastest ways to make more money without selling more, and most people never run the calculation.

The third is the cost to get a new customer. Add up what you spend on marketing and sales in a period, then divide by the number of customers that spending brought in. If you spent a thousand dollars and gained ten customers, each one cost you a hundred dollars to acquire. This matters because a customer who costs more to win than they ever spend with you is a slow leak in the boat. Knowing this number keeps you honest about which channels actually pay off and which ones just feel productive. It also tells you how aggressively you can afford to grow, since growth that loses money on every customer is not growth at all.

The fourth is the lifetime value of a customer, meaning how much an average customer spends with you over the whole relationship. A customer who buys once is worth far less than one who comes back for two years, and your whole strategy should change depending on which you have. When you compare lifetime value against the cost to acquire, you finally see whether the engine works. If a customer costs a hundred dollars to win and spends six hundred over time, you have a healthy business worth feeding. If the numbers are reversed, no amount of hustle will save it. This single comparison answers more strategic questions than any brainstorm.

The fifth is your monthly fixed costs, the money that goes out whether you sell anything or not. Rent, software, insurance, base payroll, and the rest form the floor you have to clear every single month before you earn a dollar of profit. Owners who do not know this number tend to underprice and overspend, because they have no clear target to beat. When you know your fixed cost floor, you know exactly how much you must bring in just to break even, which makes every pricing and hiring decision sharper. It turns vague worry into a concrete line you either cross or you do not.

The sixth is your break even point, which ties the others together. It is the level of sales where total money in finally equals total money out. Below it you are losing, above it you are earning, and most owners have never actually calculated where the line sits. Once you know it, you can look at any month and instantly tell whether you are on the right side of it. These six numbers will not run the business for you, but knowing them cold turns you from someone who hopes into someone who can see.
