KPIs: What are they and how do they work?

Today’s organizations have more data than ever, but without clear indicators it’s easy to lose focus. Key Performance Indicators (KPIs) translate broad objectives into measurable numbers, guiding teams on what matters most. KPIs keep everyone aligned on strategic goals and provide a realistic “health check” of performance. In this article, we explain what KPIs are, why they matter, and how to choose the right ones for your business stage and strategy.

What are KPIs (Key Performance Indicators)

A Key Performance Indicator (KPI) is a measurable value that reflects how well an organization is achieving its key business objectives. In essence, a KPI converts high-level goals into quantifiable targets. For example, a company aiming to grow might track revenue growth rate as a KPI, while a customer-support team might track average resolution time.

KPIs can be financial (like profit margin), customer-focused (like satisfaction score), or process-oriented (like production volume). They must align with your strategy and goals, a KPI for one company may be irrelevant for another. Well-defined KPIs highlight where progress is being made and where improvements are needed.

Why are they important

Proper KPIs are vital because they focus action and measure progress toward business goals. For example:

Alignment and focus

KPIs keep teams and departments working toward common goals. When everyone tracks the same success criteria, it prevents wasted effort on irrelevant activities.

Business health check

KPIs give a snapshot of overall performance. They allow leaders to see the real state of the business (not just gut feelings) and identify struggling areas early.

Accountability

Clearly tracked KPIs make it obvious who is achieving goals and who isn’t. Teams become accountable to data-driven targets instead of vague expectations.

Better decisions

Focusing on measurable indicators empowers smarter strategy. In fact, highly data-driven organizations are roughly three times more likely to report significant improvements in decision-making. By monitoring KPI trends, a company can spot problems or opportunities (for example, a sudden sales drop might trigger a review of a campaign).

Tracking the right KPIs ensures that “you can’t improve what you don’t measure.” They help prioritize effort on tactics that move the needle, driving continuous improvement and business growth.

Main KPIs

Below are ten widely used KPIs across marketing and business functions. Each metric has a specific purpose; we’ve noted when each is most pertinent:

Revenue Growth Rate

Measures how quickly sales are increasing over time. This KPI shows whether your business is scaling by attracting more customers or larger purchases. It’s especially critical for startups and growth-focused companies, where rapidly expanding the customer base is the top priority. (Keep in mind it doesn’t account for costs, so it’s best paired with profit or cash metrics.)

Customer Acquisition Cost (CAC)

The average expense to acquire a new customer. This tells you how much you’re spending on sales and marketing per customer. CAC is vital for any business looking to optimize its marketing budget – if CAC is high, you may need to adjust strategy (for example, find cheaper channels or improve targeting). This metric is most pertinent during growth phases or after launching new campaigns, to ensure customer acquisition remains cost-effective.

Customer Lifetime Value (LTV or CLV)

The total revenue a business expects from a customer over the duration of their relationship. LTV helps you understand the long-term worth of each customer. It’s often compared with CAC to assess overall profitability. This KPI is most important for subscription businesses or any company with repeat customers – it guides how much you can invest in acquisition and retention. For example, if LTV is low, you might need strategies (like new products or loyalty programs) to increase how much customers spend over time.

Conversion Rate

The percentage of prospects who take a desired action (e.g. lead to sale). In digital marketing, this often means website visitors who become leads or customers. Conversion Rate measures the efficiency of your sales funnel at each stage. It’s crucial when you’re optimizing campaigns or user experience. For instance, if only 2% of website visitors become customers, you’d investigate factors like landing page design or sales processes to improve that rate. Conversion Rate KPIs are most useful for e-commerce sites, lead-generation campaigns, and any funnel-based process.

Net Profit Margin

The percentage of revenue left after all costs (production, operations, taxes, etc.). This KPI shows overall profitability. A healthy profit margin means you’re efficiently turning sales into earnings. It’s especially important for established businesses to track profitability over time. Low or declining margins can trigger cost-cutting or price adjustments. Monitoring profit margin is critical when scaling up operations or raising funds, as it indicates whether growth is sustainable.

Customer Retention Rate (Churn Rate)

The percentage of customers who stay with your company over time. Retention and churn are two sides of the same coin. High retention (low churn) means customers are satisfied and loyal; high churn signals problems in product, service, or competition. Early-stage businesses should watch churn closely, because losing customers early can quickly stall growth. Retention Rate is also key for subscription or SaaS companies, where recurring revenue depends on keeping customers month-to-month.

Return on Investment (ROI)

The profit earned on a particular investment, expressed as a percentage. In marketing, ROI might be calculated as net profit from campaigns divided by campaign cost. This KPI tells you how efficiently investments (like marketing spend or new equipment) translate into profit. It’s crucial anytime you evaluate the payoff of an initiative. For example, after running an ad campaign, a 200% ROI means you gained $2 for every $1 spent. Teams use ROI to justify budgets and allocate resources to the most lucrative activities.

Social Media Engagement

Aggregate measures of activity on your social platforms. This can include impressions (reach), likes/comments/shares (engagement rate), follower growth, and social-driven website traffic. While these are more tactical, they gauge brand awareness and audience interest. High engagement indicates strong brand resonance or viral content. Social Media Engagement KPIs are most useful for B2C brands or companies investing heavily in social marketing, as they show which platforms and content types best amplify your message.

How to determine the right KPIs for you

Choosing the best KPIs is about aligning with your goals and context, not copying others. Consider these guidelines:

Align with Your Goals: Start by clarifying your business objectives, then pick KPIs that directly measure progress toward those.

Consider Your Stage: A startup and a mature enterprise will have different priorities. Early-stage companies often focus on growth and market validation (so metrics like user adoption or CAC payback period may be key), whereas established companies might prioritize efficiency and profitability (so profit margin or cash flow become more important).

Align KPIs with the life cycle of your business, what was critical at launch may shift as you scale.

Use SMART Criteria: Ensure each KPI is Specific, Measurable, Achievable, Relevant, and Timely. Vague targets (e.g. “get lots of users”) won’t guide action.

Be Prepared to Revisit: Business conditions change, products evolve, markets shift, technology advances. Periodically review your KPIs to make sure they still make sense. A metric that was critical last year may become obsolete next year (for example, as digital channels change).

What to keep in mind with KPIs

Avoid KPI Overload

Tracking too many KPIs can overwhelm teams and dilute focus. It’s tempting to measure everything, but that often leads to “paralysis by analysis.” Instead, select a handful of truly critical indicators that reflect your strategy.

Ensure Strategic Focus

Make sure each KPI is directly tied to a strategic objective. A common mistake is using metrics that are easy to measure instead of those that matter. KPIs not aligned with your core goals can misguide effort and waste resources.

Stay Adaptive

Don’t treat KPIs as permanent absolutes. As noted, business environments and strategies evolve. If customer behavior or your product changes, your KPIs might need to change too.

Beware of Vanity Metrics

Not all metrics are created equal. Vanity metrics (like raw download counts or social “likes”) may look impressive, but they don’t necessarily indicate success. A million app downloads mean little if none of those users pay or engage. KPIs should be actionable and tied to business value, not just “feel-good” numbers.

Our Thoughts

In the age of data, choosing the right KPIs can set your business apart. There’s no one-size-fits-all KPI – what works for one company might be irrelevant for another.

Success requires patience and iteration. It often takes time to collect enough data and experiment before your KPIs truly reflect what drives your business. Be prepared for trial and error: set KPI targets, gather results, analyze trends, and adjust as you learn. In the end, the right KPIs will help you focus on meaningful progress and continuously refine your strategy.
