KPI (Key Performance Indicator)

What is KPI (Key Performance Indicator)?

KPI is a numerical metric that measures progress toward business goals. For example, a sales department might track “monthly revenue” or “number of new customer acquisitions,” while a marketing department tracks “website visitors” or “email open rate.” These concrete numbers show whether you’re moving toward your targets. Without KPIs, it’s impossible to see whether things are going well or poorly, making effective improvement impossible.

In a nutshell: KPI is like a “thermometer that measures your company’s health.” Just as you take your temperature to determine if you’re healthy or sick, KPI shows your company’s condition.

Key points:

• What it does: Visualizes progress toward business goals through numerical indicators
• Why it’s needed: Numerical measurement clarifies improvement direction, enabling effective management decisions
• Who uses it: All management levels, sales, marketing, product, and customer success teams

Why it matters

Business contains many invisible elements. Vague judgments like “team morale is high” or “product quality is good” don’t enable management decisions. KPIs provide “objective numbers” that reveal whether actual results are being achieved.

Without KPIs, priority setting becomes unclear. For example, if a sales department cares about both “contract count” and “average deal size” but hasn’t set KPIs, it’s ambiguous which should be prioritized. When you clearly set a KPI like “increase average deal size by 30%,” all salespeople automatically understand to focus on larger deals, increasing organization-wide goal achievement.

Additionally, daily KPI monitoring enables early problem detection. “Things went smoothly last month, but suddenly dropped this month” changes become visible, enabling quick investigation and response.

Calculation methods

KPI selection varies significantly by company, department, and role. Here are examples of common calculation methods.

For sales departments:

• Revenue = Number of contracts × Average deal value
• Sales efficiency = Revenue ÷ Number of salespeople
• Win rate = Number of contracts ÷ Number of proposals

For marketing departments:

• Lead volume = Website visitors × Conversion rate (CVR)
• Customer acquisition cost (CAC) = Marketing spending ÷ Customers acquired
• LTV (customer lifetime value) = Average customer value × Average contract period

For customer success:

• Churn rate = Number of churned customers ÷ Customers at period start
• Retention rate = 1 - Churn rate
• NPS (Net Promoter Score) = (Promoters % - Detractors %) × 100

Calculation example: If 100,000 people visit a website monthly and 2% sign up for an email list, the lead volume KPI is:

Lead volume = 100,000 × 0.02 = 2,000 people

To increase next month’s leads to 2,500, you’d need to either increase visitors to 125,000 or raise CVR to 2.5%.

Benchmarks and targets

Whether a KPI is “good” or “bad” varies greatly by industry, company size, and product. However, general benchmarks include:

For SaaS companies:

• LTV/CAC ratio: 3x or higher is ideal (earn at least 3 times the acquisition cost in lifetime value)
• Monthly churn rate: 2-5% is industry average (1-2% for enterprise, 5-10% for consumer)
• NPS: 50 or above is excellent

For e-commerce companies:

• Conversion rate (CVR): 1-3% is industry average
• Cart abandonment rate: 70-80% is typical (many customers leave before purchase)
• Repeat rate: 20-40% is the guideline (varies significantly by industry)

Real-world use cases

Increasing e-commerce sales involves setting a company-wide revenue target of “10 million yen monthly,” measuring it through KPI milestones. Marketing sets “100,000 monthly site visits” as a KPI, sales sets “increase cart completion from 2% to 3%” as a KPI. Weekly KPI monitoring enables immediate corrective action if progress lags.

Improving customer satisfaction in customer success involves setting a KPI to “reduce churn from current 3% to 1.5%.” Analyzing churn causes from data leads to concrete actions like “improve onboarding process” and “implement monthly check-ins.” Monthly churn review measures initiative effectiveness.

Product development improvements track new features post-release through KPIs like “daily active users of the feature,” “feature adoption rate,” and “user session duration,” determining whether features achieve expected acceptance.

Benefits and considerations

KPI’s greatest benefit is eliminating vague judgment, enabling evidence-based management decisions. Organization-wide visibility of common numbers also facilitates inter-department cooperation.

However, over-reliance on KPIs creates problems. Setting only “contract count” as a KPI might cause salespeople to propose unrealistic terms, creating effectively unenforceable contracts. Non-measurable KPI elements (brand value, long-term trust) risk being neglected. Combining multiple KPIs to build a balanced metrics system is essential.

Frequently asked questions

Q: How many KPIs should be set? A: Too many scatter focus. Company-wide, 3-5 is standard; department-level, 5-10 is typical. Excessive KPIs obscure priorities.

Q: What if KPIs aren’t achieved? A: First, analyze root causes. Was the target too ambitious? Was execution flawed? Did market conditions change? Then improve next period’s goals and initiatives. Learning “why” is paramount.

Q: How often should KPIs be reviewed? A: Frequency varies by industry and metric. Multi-layered approaches work well: daily numbers (reports), weekly checks, monthly reviews. Long-term targets need quarterly review at minimum.
