The SaaS Founder’s Guide to Seed Stage Fundraising Metrics

Demonstrate a clear grasp of these metrics, and you’re well on your way to building investor confidence and securing capital to fuel your SaaS startup’s growth.

Raising outside capital is a major milestone for early-stage SaaS startups. Understanding and tracking the right metrics is a key factor that can make or break your chances of securing funding. This article will guide you through the most important metrics to track for a successful Seed funding round from VCs or other institutional investors.

For startups outside of the SaaS space—where consumer acquisition occurs later in the company’s evolution—several different metrics may apply. Stay tuned for more articles to follow, where we’ll address the critical metrics for startups in other industries including healthcare, fintech, and cleantech.

SaaS Metrics for Seed Stage Funding

At Seed stage, investors will focus on validating the potential of your business idea. The primary goal is to demonstrate market potential, product-market fit, and early traction. Here are seven key metrics to track, with simple formulas and considerations for each.

1. Total Addressable Market (TAM)

Total Addressable Market estimates the overall revenue opportunity available if your product achieves 100% market share. A large TAM indicates significant growth potential and can justify a higher valuation during fundraising rounds.

Prospective investors will expect you to have a clear grasp of your Total Addressable Market (TAM), the portion of that market you aim to capture, and the reasons why your business is uniquely positioned to achieve this. This involves demonstrating a deep understanding of the problem you’re solving, identifying who your paying customers are, and thoughtfully analyzing the competitive landscape. By addressing these elements, you show investors that you have a well-defined strategy and a realistic pathway to success.

  • Simple Formula: Estimate your TAM using the top-down, bottom-up, or value theory approach.
  • Example: If your product targets a market valued at $1 billion, this is your TAM.
  • Considerations: Remember the “10x Rule”, which suggests that VCs generally look for investment opportunities with a minimum of 1,000% growth potential.


2. Customer Acquisition Cost (CAC)

Customer Acquisition Cost measures the average dollar cost of acquiring a new customer. It’s crucial for early-stage SaaS startups to keep CAC as low as possible while demonstrating the ability to effectively acquire customers.

  • Simple Formula: CAC = Total Sales and Marketing Expenses / Number of New Customers Acquired
  • Example: If you spend $10,000 on marketing and acquire 100 customers, your CAC is $100.
  • Considerations: Lower your CAC by focusing on targeting your most likely customers, optimizing your marketing channels, leveraging word-of-mouth and referrals, and continuously testing and refining your acquisition strategies.

3. Lifetime Customer Value (LTV)

Lifetime Customer Value estimates the total revenue your business can expect from a single customer over the entire relationship. It shows the long-term value of your customer base.

  • Simple Formula: LTV = (Average Revenue per Account (ARPA) × Gross Margin %) / Revenue Churn Rate
  • Example: If your ARPU is $50 per month, your gross margin is 70%, and your customer lifespan is 24 months, your LTV is $840.
  • Considerations: To boost your LTV, focus on enhancing customer satisfaction, offering exceptional customer service, upselling and cross-selling additional products or services, implementing loyalty programs, and continuously improving your offering to meet evolving customer needs.

4. LTV:CAC Ratio

LTV:CAC leverages the two SaaS metrics above to compare the average lifetime value of a customer to the average cost of acquiring a customer. This metric helps investors understand the efficiency and profitability of your customer acquisition strategy.

  • Simple Formula: LTV:CAC Ratio = Lifetime Value (LTV) / Customer Acquisition Cost (CAC)
  • Example: Working from the two examples above, if your LTV is $840 and your CAC is $100, your LTV:CAC is 8.4, indicating a strong return on investment for customer acquisition.
  • Considerations: Aim for a LTV:CAC of at least 3:1, meaning that the value of a customer should be at least three times the cost of acquiring one. A higher ratio indicates a more efficient and profitable customer acquisition strategy.


5. Annual Recurring Revenue (ARR)

Annual Recurring Revenue tracks the predictable and recurring revenue components of your SaaS business. It indicates growth and stability.

  • Simple Formula: ARR = Number of Paying Customers × Average Revenue per Customer (ARPC)
  • Example: If you have 300 customers, each paying $100 per month, your ARR is $360,000.
  • Considerations: Demonstrate steady growth in ARR to indicate a growing customer base and revenue base. The median ARR growth rate for SaaS startups generating less than $10M ARR was 50% in 2023, according to KeyBanc’s annual SaaS survey.



6. Customer Retention Rate

Customer Retention Rate measures the percentage of customers who continue to use your product over a specific period. High retention rates indicate customer satisfaction and a viable product.

  • Simple Formula: Customer Retention Rate= ((Customers at End of Period − Customers Acquired During Period) / Customers at Start of Period) × 100
  • Example: If you start with 100 customers, acquire 50 new ones, and end with 120, your retention rate is 70%.
  • Considerations: A good customer retention rate for an early-stage startup can vary depending on the industry and the type of business. In general, a retention rate of around 85-90% is considered good for most SaaS and subscription-based businesses. For other types of startups, maintaining a retention rate above 70-75% is usually a positive indicator of customer satisfaction and product-market fit.

7. Burn Rate

Your startup’s burn rate is the rate at which the company is spending its available cash resources, usually tracked by month. Maintaining a manageable burn rate is essential for sustaining operations and demonstrating fiscal responsibility to investors.

  • Simple Formula: Burn Rate = ((Starting Cash Balance + New Revenue) − Ending Cash Balance) / Number of Months)​
  • Example: If you started a 6-month period with $500,000, generated $100,000 in additional revenue during the period, and ended with $400,000, your burn rate is $33,333 per month.
  • Considerations: A burn rate that is too high indicates overspending and possible inefficiencies, while an extremely low burn rate could hint at missed growth opportunities. Tracking your monthly burn rate helps ensure you don’t run out of cash runway while investing in your startup’s growth.
