The KPIs Every Small Business Should Track
Running a small business comes with endless decisions, from pricing and marketing to hiring and budgeting. But making smart decisions isn’t about guessing or hoping; it’s about understanding the numbers behind your business. That’s where KPIs, or Key Performance Indicators, come in.
KPIs help you measure how well your business is performing, identify areas for improvement, and stay focused on the metrics that truly matter. Whether you're just getting started or looking to level up your operations, here are the essential KPIs every small business should track.
1. Revenue Growth
Revenue growth tells you whether your business is expanding, shrinking, or stuck in place. Tracking month over month or year over year growth helps you spot trends early and make proactive decisions.
Why it matters:
Healthy revenue growth shows demand for your product or service and signals business sustainability.
How to calculate:
> (Current Revenue – Previous Revenue) ÷ Previous Revenue × 100
2. Net Profit Margin
Revenue is great, but profit keeps your business alive. Net profit margin reveals how much of your revenue you actually keep after expenses.
Why it matters:
It shows financial efficiency and overall profitability.
How to calculate:
> Net Profit ÷ Total Revenue × 100
3. Cash Flow
Cash flow measures the money moving in and out of your business. Even profitable companies can fail if cash flow runs dry.
Why it matters:
Strong cash flow ensures you can cover bills, invest in growth, and handle unexpected expenses.
Pro tip:
Consider tracking both operational cash flow and free cash flow for a fuller picture.
4. Customer Acquisition Cost (CAC)
CAC tells you how much you spend to acquire a new customer, including marketing, advertising, and sales costs.
Why it matters:
If CAC gets too high, your growth becomes unsustainable.
How to calculate:
> Total Sales & Marketing Costs ÷ Number of New Customers Acquired
5. Customer Lifetime Value (CLV)
CLV estimates the total revenue a customer will generate over the lifespan of your relationship.
Why it matters:
High CLV means stronger brand loyalty and more consistent revenue. It also helps you determine how much you should spend to acquire customers.
6. Gross Margin
Gross margin shows how much money you make after covering the direct costs of delivering your product or service.
Why it matters:
A healthy margin gives you room to invest in marketing, staff, and growth.
How to calculate:
> (Revenue – Cost of Goods Sold) ÷ Revenue × 100
7. Conversion Rate
Your conversion rate measures how many leads or website visitors turn into paying customers.
Why it matters:
It reflects the effectiveness of your sales process, website, or marketing funnel.
Where to track:
Website conversion rate
Email campaign conversion
Lead-to-customer conversion
8. Customer Retention Rate
Acquiring customers is expensive, keeping them is far more profitable. This KPI reveals how many customers stick around.
Why it matters:
High retention improves revenue predictability and boosts CLV.
9. Employee Productivity
For small teams, every hour counts. Productivity KPIs help you measure output relative to time or cost.
Why it matters:
It highlights workflow inefficiencies and helps you optimize staffing.
10. Inventory Turnover (for product-based businesses)
Inventory turnover shows how quickly you sell your stock.
Why it matters:
Slow turnover means tied-up cash and possible losses; fast turnover indicates strong demand and healthy cash flow.
