Startups thrive on data-driven decisions. To succeed, track these six key metrics monthly:
- Customer Acquisition Cost (CAC): How much you spend to acquire a customer. Lower it by targeting the right audience and optimizing marketing.
- Monthly Recurring Revenue (MRR): Your predictable monthly income. Focus on pricing models and customer retention to grow it.
- Churn Rate: Percentage of customers lost over time. Reduce it with better onboarding and proactive support.
- Burn Rate: How fast you’re spending cash. Manage it by cutting unnecessary costs and tracking expenses.
- Customer Lifetime Value (CLV): Total revenue from a single customer. Boost it with loyalty programs and upselling.
- Net Promoter Score (NPS): Measures customer satisfaction and likelihood of referrals. Improve it by acting on customer feedback.
Why These Metrics Matter
- CAC vs. CLV: Ensure you’re acquiring profitable customers.
- MRR vs. Burn Rate: Balance revenue growth with spending.
- Churn Rate + NPS: Retain happy customers for long-term success.
Tracking these metrics together provides a clear view of growth, financial health, and customer satisfaction. Use them to make smarter, data-backed decisions for sustainable growth.
Startup Metrics & KPIs: Top 10 Metrics Used by VCs
1. Customer Acquisition Cost (CAC)
Customer Acquisition Cost (CAC) tracks how much your startup spends to bring in new customers, offering insight into how sustainable your growth is [2].
How to Calculate CAC
To find your CAC, divide your total sales and marketing expenses by the number of new customers acquired. For instance, if you spent $20,000 on marketing and sales in Q1 2023 and gained 500 new customers, your CAC would be $40 per customer.
Make sure to include:
- Marketing and advertising expenses
- Sales costs (like salaries and commissions)
- Software, tools, and overhead
- Legal and administrative costs
Why CAC Matters
Compare your CAC to Customer Lifetime Value (LTV) to ensure a healthy balance. A good benchmark is a 3:1 LTV to CAC ratio. If it’s closer to 1:1, that’s a red flag [2] [3].
Tips to Lower CAC
Content marketing can be a game-changer – it’s 62% cheaper and generates 6 times more leads than traditional methods. Plus, retaining customers is far more cost-effective than acquiring new ones, which can cost five times as much [5].
"Reducing CAC isn’t about cutting corners; it’s about making smarter, data-driven decisions. It’s about identifying inefficiencies, refining processes, and enhancing customer experiences. It’s about investing wisely, not simply spending less." – AtData [4]
To bring down your CAC, consider these strategies:
- Target your Ideal Customer Profile with precision
- Use A/B testing to boost conversion rates
- Improve your website’s user experience
- Build a strong lead scoring system
- Create content that directly addresses customer pain points
- Partner with businesses that complement your offerings
Focusing on these areas not only helps manage acquisition costs but also sets the stage for evaluating recurring revenue metrics.
2. Monthly Recurring Revenue (MRR)
Monthly Recurring Revenue (MRR) represents the steady income your business earns from subscriptions and regular customers. Similar to CAC, MRR provides a quick view of your startup’s financial health and helps guide important decisions [6].
How to Calculate MRR
To calculate MRR, multiply the number of paying customers by the monthly Average Revenue Per User (ARPU). Here’s an example with three subscription tiers:
| Plan Level | Monthly Cost | Number of Customers | MRR |
|---|---|---|---|
| Basic | $10 | 100 | $1,000 |
| Pro | $20 | 50 | $1,000 |
| Enterprise | $30 | 30 | $900 |
| Total | 180 | $2,900 |
This method provides a clear breakdown of your revenue streams.
Key Components of MRR
Breaking MRR into specific categories can help you better understand growth patterns [6]:
- New MRR: Revenue from newly acquired customers.
- Expansion MRR: Additional revenue from upselling or cross-selling to existing customers.
- Churn MRR: Revenue lost due to cancellations.
- Reactivation MRR: Revenue from customers who return after leaving.
- Net New MRR: The overall effect of all MRR changes combined.
Common MRR Calculation Mistakes
Avoid these common pitfalls when calculating MRR:
- Including one-time fees or non-recurring revenue.
- Counting free trial users.
- Failing to normalize annual subscriptions into monthly amounts.
- Overlooking discounts or coupons.
Strategies to Increase MRR
Looking to grow your MRR? Here are some effective tactics:
- Use pricing models that reflect the value customers gain from your product.
- Improve your customer onboarding process to reduce early churn.
- Build a strong customer success team to ensure satisfaction and retention.
- Offer discounts for annual subscriptions to encourage long-term commitments.
- Leverage analytics to identify and address churn risks.
- Focus on niche markets where your product can stand out.
- Form strategic partnerships to expand your reach.
Growth Indicators
Achieving a 10% monthly MRR growth rate can double your revenue in just seven months [6]. To ensure sustainable growth, monitor MRR alongside CAC. Next, we’ll dive into customer retention by exploring the churn rate metric.
3. Churn Rate
Churn rate measures how many customers your business loses over a specific period. It’s a key metric for startups because keeping current customers is far cheaper than finding new ones – customer acquisition can cost 5 to 25 times more [10].
Industry Benchmarks for Churn
Here’s a look at typical annual churn rates across industries:
- SaaS: 5–7% annually (0.4–0.6% monthly) [9]
- Early-stage startups: 10–15% [9]
- E-commerce: As high as 70–80% [7]
- Logistics: Around 40% [7]
Just like CAC (Customer Acquisition Cost) and MRR (Monthly Recurring Revenue), churn rate offers a clear view of your business’s financial health and operational efficiency.
How to Calculate Churn Rate
There are two main ways to measure churn:
- Customer Churn: If you start with 500 customers and drop to 450, your churn rate is 10% [8].
- Revenue Churn: If your MRR starts at $500,000 and ends at $450,000, but you gain $65,000 in upgrades, your net revenue churn is -3% [8].
Spotting changes in customer behavior early can help you address churn before it escalates.
Red Flags for High Churn
Watch for these signs to identify at-risk accounts:
- Declining login frequency
- Shorter session durations [8]
These behaviors often indicate customers are disengaging.
Ways to Reduce Churn
Here are some practical steps to keep your customers around:
- Offer Proactive Support: Address issues early to minimize friction.
- Educate Customers: Train your support team to build stronger relationships.
- Use Personalized Messaging: Create targeted campaigns to win back lost customers.
- Build a Community: Encourage early adopters to become brand advocates.
"Customer churn rate is a crucial metric that can shine a light on a company’s shortcomings and reveal areas of improvement." – Kenza Moller, Contributing Writer, Zendesk [7]
Actions to Take
To tackle churn effectively:
- Build customer feedback systems like VoC (Voice of Customer) and conduct exit interviews.
- Create thorough onboarding materials and educational resources.
- Offer 24/7 customer support to resolve issues quickly.
- Track usage data to identify customers who may leave [8].
Once you’ve addressed churn, you’ll be ready to turn your attention to managing your burn rate.

4. Burn Rate
Burn rate refers to how quickly your startup uses up cash. It’s a critical metric for determining how long your business can operate without additional funding and helps guide financial decisions.
Types of Burn Rate
There are two main ways to measure burn rate:
- Gross Burn Rate: Your total monthly operating costs.
- Net Burn Rate: The amount you lose each month, calculated as expenses minus revenue.
For instance, if your startup spends $10,000 a month and brings in $5,000 in revenue, your gross burn rate is $10,000, while your net burn rate is $5,000 [11].
Calculating Your Runway
Runway is the amount of time your startup can continue operating before it runs out of cash. Here’s an example from a SaaS startup:
| Initial Cash | Monthly Expenses | Monthly Revenue | Net Burn | Runway |
|---|---|---|---|---|
| $100,000 | $10,000 | $5,000 | $5,000 | 20 months |
With $5,000 in revenue, the startup has a 20-month runway. Without revenue, the runway drops to just 10 months [12]. This calculation is vital for managing cash reserves and planning for future stability.
Best Practices for Burn Rate Management
Experts suggest keeping at least six months’ worth of cash reserves based on your current burn rate [13]. Many startups aim to secure additional funding when their runway falls to 5–8 months [12].
Red Flags for an Unhealthy Burn Rate
Watch out for these warning signs:
- Cash reserves covering less than three months of expenses.
- Spending that exceeds industry benchmarks.
- Increasing costs without matching revenue growth.
Tips to Manage Your Burn Rate
Here are some steps to keep your burn rate under control:
- Review Regular Expenses: Look for savings in fixed costs like office leases or software subscriptions.
- Focus Marketing Spend: Invest in marketing channels that deliver clear returns.
- Leverage Automation: Use tools to cut labor costs and boost efficiency.
- Track Variable Costs: Keep an eye on fluctuating expenses to identify quick savings [13].
These strategies can help you reduce cash outflow while ensuring your startup stays on track for long-term growth.
Why Burn Rate Matters
Poor management of burn rate is a leading cause of startup failure, contributing to the downfall of 29% of businesses [14]. Keeping a balanced burn rate allows you to:
- Make smart decisions about hiring and scaling.
- Maintain leverage when negotiating with investors.
- Avoid scrambling for funds under time pressure.
- Prioritize sustainable growth over short-term fixes.
5. Customer Lifetime Value (CLV)
Customer Lifetime Value (CLV) helps estimate the total profit a business can expect from a single customer. Understanding this metric allows you to make smarter decisions about marketing and spending.
Why CLV Matters for Startups
Boosting customer retention by just 5% can lead to profit increases ranging from 25% to 95% [15]. That’s why CLV is a game-changer for startups looking to grow sustainably.
Calculating CLV
For SaaS startups, CLV can be calculated with a straightforward formula that uses a few key metrics:
| Component | Formula | Example |
|---|---|---|
| Monthly Revenue | Average subscription price × active users | $50 × 100 = $5,000 |
| Customer Lifespan | 1 ÷ monthly churn rate | 1 ÷ 0.03 ≈ 33.3 months |
| Total CLV | Monthly Revenue × Customer Lifespan | $5,000 × 33.3 ≈ $166,500 |
Key Performance Indicator
A good benchmark for the CLV-to-Customer Acquisition Cost (CAC) ratio is 3:1 [16]. For example, if it costs $1,000 to acquire a customer, that customer should generate at least $3,000 in profit over their lifetime.
Strategies to Increase CLV
-
Enhance Customer Experience
Deliver outstanding service. Research shows 86% of customers are willing to pay more for a better experience [18]. -
Introduce Loyalty Programs
Rewarding loyal customers can pay off big time – 80% of businesses with loyalty programs report positive ROI [19]. -
Use Referral Marketing
Referred customers tend to be more valuable, with a 16% higher lifetime value compared to customers from other channels [10].
Monitoring and Optimization
Emmanuel Thomassin, CFO of Delivery Hero, highlights the importance of CLV:
"CLV is our core steering metric." [17]
Regularly track metrics like customer satisfaction, average order value, purchase frequency, retention rates, and upsell opportunities to keep improving your CLV.
Warning Signs
Watch out for trends that might indicate a declining CLV, such as:
- Dropping average order values
- Longer gaps between purchases
- A rise in customer complaints
- Lower engagement metrics
- Higher churn rates
It’s worth noting that existing customers are 31% more likely to spend more than new ones [15].
Best Practices for CLV Management
Maximizing CLV requires personalization and targeted engagement. Use customer data to uncover trends and preferences, and regularly collect feedback through surveys or interviews. Address potential issues early to reduce churn. This approach not only boosts CLV but also strengthens your startup’s overall financial health.
6. Net Promoter Score (NPS)
NPS offers insights into customer satisfaction and loyalty, complementing financial metrics by focusing on how customers feel about your product. The key question it asks is: "How likely are you to recommend our product?" This makes it a great indicator of how well your product connects with users and its potential for growth.
How NPS Works
Customers rate their likelihood to recommend your product on a scale from 0 to 10. Based on their responses, they fall into one of three groups:
| Category | Score Range | Characteristics |
|---|---|---|
| Promoters | 9–10 | Enthusiastic customers who are likely to refer others |
| Passives | 7–8 | Satisfied but not overly enthusiastic |
| Detractors | 0–6 | Unhappy customers who may share negative feedback |
To calculate your NPS, subtract the percentage of Detractors from the percentage of Promoters. For instance, if 60% of respondents are Promoters and 20% are Detractors, your NPS would be 40.
Why NPS Matters for Startups
Promoters are incredibly valuable – they can generate 6 to 14 times more lifetime value compared to Detractors [20]. Plus, 64% of marketers believe word-of-mouth is the most effective form of marketing [21]. For startups, a solid NPS score often reflects strong product-market fit, which is crucial for long-term success.
Implementation Timeline
Here’s a simple schedule for rolling out NPS surveys:
- Initial survey: Send 7–30 days after a customer’s first interaction with your product.
- Follow-up surveys: Repeat every 30–60 days to stay updated on customer sentiment.
- Response review: Analyze feedback weekly to identify trends and actionable insights.
Setting Benchmarks
Bain & Company provides these benchmarks for interpreting your NPS:
- Above 0: Good
- Above 20: Great
- Above 50: Excellent
- 70+: Industry-leading [20].
Tips for Collecting NPS Data
To get the most out of NPS, focus on these strategies:
- Keep Surveys Short: Ask for a score and include space for open-ended feedback.
- Use Multiple Channels: Distribute surveys via email, in-app prompts, social media, or chat tools.
- Analyze Feedback: Break down responses by demographics, spending habits, feature usage, and more to identify patterns.
Boosting Your NPS
Want to improve your score? Here are some practical steps:
- Follow Up with Detractors: Understand their concerns and work to address them.
- Encourage Promoters: Motivate happy customers to share their experiences.
- Close the Loop: Let customers know how their feedback has led to changes.
- Train Support Teams: Use NPS insights to enhance customer service efforts.
Measuring the Impact
Beyond the score itself, track metrics like retention rates, referral traffic, social mentions, support ticket trends, and feature adoption. Around 48% of businesses rely on word-of-mouth to drive revenue growth [21], so monitoring these areas can help you gauge how NPS affects your bottom line.
Conclusion
Tracking the right metrics is essential for guiding startup growth. The six metrics we’ve covered – CAC, MRR, Churn Rate, Burn Rate, CLV, and NPS – provide a clear view of performance and help identify areas for improvement.
Combining Metrics for Better Insights
Using these metrics together can uncover deeper insights:
| Metric Combination | Insight Gained | Suggested Action |
|---|---|---|
| CAC + CLV | Customer profitability | Focus on acquisition channels with the best ROI |
| MRR + Burn Rate | Financial health | Adjust spending to ensure sustainable growth |
| Churn Rate + NPS | Customer retention and satisfaction | Use feedback to improve customer experience |
By analyzing these combinations, you’ll get a clearer picture of growth trends and operational efficiency, which helps you make informed adjustments.
Putting Metrics into Action
Here’s how to apply this strategy effectively:
- Set Clear Goals: Define specific targets for each metric based on your industry and growth stage.
- Use Analytics Tools: Automate data collection and focus on interpreting results to guide decisions.
- Make Strategic Changes: If metrics reveal issues – like rising CAC but stable CLV – adjust marketing tactics, refine your audience, or improve conversion strategies.
"Tracking key metrics is not just a matter of collecting numbers; it’s about gaining valuable insights into the health and trajectory of your early-stage startup" [1].
Staying Ahead
These six metrics act as both warning systems and indicators of success. For instance, a high NPS paired with increasing MRR and low churn signals strong product-market fit and growth potential. Regular monitoring and analysis allow you to base decisions on solid data, not guesswork.
