As a small business owner, it’s easy to get caught up in day-to-day responsibilities, such as sales, customer service, operations, and just keeping things moving forward. But if you’re not regularly looking at your numbers, you’re pretty much flying blind. Luckily, tracking a few key financial metrics each month can help you make smarter decisions, catch red flags early, and keep your business on solid ground.
In this blog, we’ll explore five essential financial metrics that every small business should monitor on a monthly basis.
1. Net Profit (a.k.a. What You Actually Keep)
This indicates the amount of money your business earned after covering all expenses, including payroll, rent, materials, and taxes. It’s the true measure of profitability.
How to track it: Subtract your total expenses from your total revenue. If you’re working with a bookkeeper, this should be a number you see in your Profit & Loss (P&L) statement every month.
Pro tip: If your revenue is growing but your profit isn’t, it might be time to look at what’s eating into your margins.
2. Cash Flow
Profit doesn’t pay the bills—cash does. Cash flow tells you how much money is moving in and out of your business and whether you have enough on hand to cover your obligations.
How to track it: Look at your cash inflows (sales, payments received) versus outflows (expenses, loan payments, payroll). Positive cash flow means there’s more coming in than going out.
Pro tip: If possible, maintain a 2–3 month cash reserve. That buffer can make or break your business in slow seasons.
3. Accounts Receivable (A/R) Aging
Are you getting paid on time? This metric tracks how much money you’re owed and how long it’s been outstanding.
How to track it: Your accounting software or bookkeeper can run an “A/R Aging Report” to show what’s due and what’s late.
Pro tip: The longer an invoice goes unpaid, the less likely it is to get paid. Don’t let money slip through the cracks.
4. Gross Profit Margin
This indicates how efficiently your business produces goods or services. It’s your revenue minus cost of goods sold (COGS), divided by revenue.
How to track it: Review it monthly to identify if rising costs or pricing issues are affecting your margins.
Pro tip: If your gross margin is shrinking, but your sales volume is the same, you may be undercharging—or overspending.
5. Operating Expenses as a % of Revenue
This illustrates how much of your income is consumed by day-to-day expenses. It helps you assess whether your overhead is sustainable as your business grows.
How to track it: Divide your total operating expenses (excluding COGS) by your total revenue.
Pro tip: If this percentage continues to climb month after month, it may be time to review your subscriptions, staffing, or unnecessary spending.
