Most small business owners check their bank balance and call it financial management. Here are the seven numbers that actually tell you whether your business is healthy — and how to calculate each one from data you already have.
You don't need an MBA or a CFO to manage your business finances well. You need seven numbers, updated monthly. Most of them take under five minutes to calculate if your books are clean. All of them are available in QuickBooks right now.
The real problem isn't access to information — it's knowing which numbers to look at and what they mean when they move.
Formula: (Revenue − Cost of Goods Sold) ÷ Revenue × 100
This is the most fundamental indicator of whether your core business model works. Gross margin tells you how much of every revenue dollar remains after you account for the direct cost of delivering your product or service — before overhead, salaries, and fixed costs.
Benchmarks by industry:
If your gross margin is below your industry benchmark, your pricing, your COGS, or both have a problem. Everything else on this list is downstream of gross margin — you cannot fix net profit without first understanding why gross margin is where it is.
Formula: Net Income ÷ Revenue × 100
What's actually left after everything — COGS, overhead, payroll, rent, debt service, taxes. A 10% net profit margin is generally considered healthy for a mature small business across most industries. Under 5% and you're one bad month from breaking even. Under 2% and you're working very hard for very little cushion.
Track net margin monthly and watch the direction. A business running 9% net margin declining to 7% over three months has a cost structure problem emerging — even if the absolute number still looks fine.
Formula: Current Assets ÷ Current Liabilities
Measures short-term financial health — specifically, whether you have enough liquid assets to cover obligations coming due within the next 12 months. Target: above 1.5. Below 1.0 means your short-term obligations exceed your liquid assets. That's dangerous territory: a single delayed receivable or unexpected expense can create a cash crisis.
Current assets include cash, accounts receivable, and inventory. Current liabilities include accounts payable, short-term debt, and any portion of long-term debt due within 12 months.
Formula: Average Accounts Receivable ÷ (Annual Revenue ÷ 365)
DSO tells you how long it takes to collect what you're owed. Under 30 days is healthy for most businesses. Above 60 days means your cash is stuck in unpaid invoices and compounding — you're effectively financing your customers' operations with your own working capital.
A rising DSO trend is a warning sign even if the absolute number looks tolerable. If your DSO was 28 days in Q1 and is 41 days in Q3, your collection process has degraded or your customer base has shifted toward slower payers. Either requires action.
Formula: Total Revenue ÷ Total Headcount (FTE)
Tracks labor productivity over time. There is no universal target — revenue per employee varies enormously by industry — but the direction of the trend matters. Declining revenue per employee means your team is growing faster than your revenue, which is a margin compression signal. Flat revenue per employee during a growth phase means you're scaling efficiently. Rising revenue per employee means you're getting more productive.
Calculate this monthly using the same headcount definition every time. Use FTE equivalents if you have significant part-time staff.
Formula: Monthly Gross Profit ÷ Monthly Fixed Costs
Tells you how many times over your gross profit covers your unavoidable monthly costs — rent, insurance, fixed salaries, loan payments. Target: above 1.5x. Below 1.2x and a slow revenue month becomes an emergency. Below 1.0x and your gross profit doesn't cover your fixed costs at all — you are losing money on every dollar of variable expense before overhead.
This ratio should be part of your monthly close review. It's the earliest indicator that your cost structure is growing faster than your revenue base.
Formula: Average of current month + prior 2 months, compared to prior 3-month average
Not just "is revenue up or down this month" — but what is the direction and momentum of your revenue over time. A business doing $80K → $76K → $72K is in a declining trend even if $72K would have felt fine two years ago. A business doing $68K → $71K → $74K has positive momentum even if it's not at target yet.
Single-month revenue is too noisy for strategic decisions. The rolling 3-month average smooths seasonality and one-off events to reveal the actual trend line. This is the number your bank looks at when you apply for a line of credit. It's worth knowing it yourself first.
Every formula above takes under two minutes to calculate in a spreadsheet. The real friction is that most small business owners don't have their books organized in a way that makes these calculations easy or fast. Chart of accounts inconsistencies, uncategorized transactions, and mixed personal/business expenses all create noise that makes the numbers unreliable — or so tedious to produce that they never get calculated at all.
A clean QuickBooks setup plus a monthly review habit — two hours on the first Friday of every month — is genuinely all it takes to run your finances better than 80% of small businesses your size.
