Top 5 KPIs Every Small Business Should Track

It’s Friday afternoon, and you’re reviewing the week’s results. Sales are up—but you’re not sure which ad campaign sparked the boost. Customer service is busier than ever—but does that mean your support quality is slipping? As an owner of a small business, you might feel like you’re constantly juggling unknowns.

This is where Key Performance Indicators (KPIs) come in. Rather than drowning in guesswork, you gain specific metrics that highlight what’s really happening in your business. In this post, we’ll explore five must-track KPIs that every SMB can benefit from—whether you’re a local shop or an online coaching platform. Implementing these metrics could be the game-changer you’ve been waiting for.

Customer Acquisition Cost (CAC)

‍

Why Your Customer Acquisition Cost (CAC) Matters

Imagine spending thousands on a flashy billboard campaign, only to realize later that each new customer acquired cost you more than they’ll ever spend with you. Customer Acquisition Cost (CAC) ensures you’re not throwing money into the wind. By measuring how much it costs—on average—to gain a new customer, you can allocate your marketing budget wisely.

How to Calculate Customer Acquisition Cost (CAC)

\[

\text{CAC} = \frac{\text{Total Marketing \& Sales Expenses}}{\text{Number of New Customers Acquired}}

\]

Real-World Example of Customer Acquisition Cost (CAC)

A startup offering subscription-based meal kits discovered that Facebook Ads had a much higher CAC compared to Google Search Ads. They shifted budget allocation, driving down overall CAC by 20% in just one quarter.

Lifetime Value (LTV)

‍

Why Lifetime Value (LTV) Matters

Do your customers keep coming back, or do they vanish after one purchase? Lifetime Value (LTV) is the total revenue you can reasonably expect from a customer over the course of their relationship with your brand. A high LTV typically indicates strong loyalty and a good product-market fit.

How to Calculate Lifetime Value (LTV)

\text{LTV} = \text{Average Purchase Value} \times \text{Number of Purchases per Year} \times \text{Average Customer Lifespan (in years)}

Pro Tip for Lifetime Value (LTV)

Compare LTV to CAC. If CAC > LTV, you’re essentially paying more to acquire customers than you’ll ever earn. In that scenario, you might need to revise your pricing, customer retention, or marketing strategy immediately.

‍

Conversion Rate

‍

Why Conversion Rate Matters

You could be generating thousands of website visits, but if only a tiny fraction convert into paying customers, your top-of-funnel metrics don’t count for much. Conversion Rate is the percentage of people who complete a desired action—like signing up for a newsletter or purchasing a product.

How to Calculate Conversion Rate

\text{Conversion Rate} = \left(\frac{\text{Total Conversions}}{\text{Total Visitors/Leads}}\right) \times 100

Real-World Example of Conversion Rate

A small e-commerce brand selling skincare products ran two Facebook Ad campaigns. By tracking conversion rates, they found that ads featuring real customer testimonials converted 2x higher than ads focusing solely on product benefits. Knowing this, they pivoted their entire ad strategy toward user-generated content, doubling their overall conversion rate in one month.

‍

Customer Churn Rate

‍

Why Customer Churn Rate Matters

In a subscription-driven world, retaining your existing customers is often more cost-effective than finding new ones. Churn Rate reveals how many customers stop doing business with you over a specific timeframe.

How to Calculate Customer Churn Rate

\text{Churn Rate} = \left(\frac{\text{Number of Customers Lost in a Period}}{\text{Total Customers at the Start of Period}}\right) \times 100

Pro Tip for Customer Churn Rate

Identify the root causes. Is your onboarding unclear? Are support response times too slow? By digging into the “why” behind churn, you can plug those holes and keep more of your hard-earned customers.

‍

Gross Profit Margin

‍

Why Gross Profit Margin Matters

A high volume of sales might look good on paper, but what’s left after Cost of Goods Sold (COGS)? Gross Profit Margin measures how efficiently you turn revenue into actual profit before overhead costs like rent, salaries, and marketing.

How to Calculate Gross Profit Margin

\text{Gross Profit Margin} = \left(\frac{\text{Revenue} - \text{COGS}}{\text{Revenue}}\right) \times 100

Real-World Example of Gross Profit Margin

A custom T-shirt printing business realized that due to rising material costs, their gross profit margin dropped from 40% to 25%. They negotiated better wholesale pricing with suppliers and introduced a slight price increase for customers. As a result, margins rebounded to 38% in just two months.

‍

How to Put KPIs into Action

‍

Collecting KPI data is only half the battle. The real power comes from acting on the insights:

1. Set Targets: Use industry benchmarks or your historical performance to set monthly or quarterly targets.

2. Review Regularly: Schedule weekly or monthly KPI check-ins with your team. Look for trends—both positive and negative.

3. Experiment & Optimize: If your churn rate is climbing, run targeted experiments to see what reduces churn—like upgrading customer support or improving the user experience.

4. Celebrate Wins: Hit a new low in CAC? Share that success with your team to boost morale and reinforce a data-driven culture.
