If you’re a founder looking to grow your startup in 2025 and beyond, it’s not just about working hard — it’s about working smart. This blog gives you a simple, grade-5-friendly breakdown of the 19 most important startup metrics that every founder needs to watch. These numbers help you understand your money, your customers, and how fast you’re growing.
Why Startup Metrics matter?
Startup metrics are the key signs that show whether your business is on track. Think of them like the dashboard on a car. If you ignore the fuel gauge or speedometer, you might run out of gas or crash. Metrics work the same way for your business.
When you measure the right things, you can:
Make smarter decisions.
See where your business is growing.
Fix problems before they grow too big.
Build a brand that lasts.
No matter your industry, these metrics help you spot trends, track performance, and keep your team focused. So let’s explore the 19 startup metrics every founder should know and track.
Financial Metrics: Track your money flow
These numbers help you understand how much you earn, how much you spend, and how long your cash will last. Without this data, it’s easy to run into trouble.
1. Monthly Recurring Revenue (MRR)
MRR is the amount of predictable income your startup earns each month, especially important for subscription-based services.
Why it matters: It shows how much money you can count on regularly.
Pro tip: Break it down into New MRR, Expansion MRR, and Churned MRR to see where growth comes from.
2. Net Profit
This is what’s left after you subtract all your costs (like rent, salaries, and marketing) from your revenue.
Why it matters: It tells you if your business is actually making money.
Real tip: If you’re not making a profit yet, keep an eye on this to work toward profitability.
3. Gross Margin
This is the percentage of money left after paying for the product or service you sell.
Formula: (Revenue – Cost of Goods Sold) ÷ Revenue × 100
Why it matters: A healthy margin means you’re earning more than you spend to make your product.
4. Cash Runway
Cash runway is how long your business can survive with the money you have.
Why it matters: You need to know when to raise funds or cut costs before the money runs out.
Bonus tip: Aim for 12–24 months of runway to stay in the safe zone.
5. Burn Rate
This shows how fast you’re spending your cash every month.
Why it matters: It helps you avoid running out of money too soon.
Advice: Monitor it monthly so you don’t burn through your budget.
Customer Metrics: Understand customer value
These numbers tell you how much it costs to get a customer and how much value they bring over time.
6. Contract Value
Contract value is the size of the deals you make with customers.
Why it matters: Helps forecast revenue and evaluate the value of each customer.
Two types: Total Contract Value and Annual Contract Value.
7. Customer Acquisition Cost (CAC)
CAC is the average amount you spend to get a new customer.
Why it matters: Lower CAC means more efficient growth.
Formula: Total marketing + sales cost ÷ Number of new customers
8. Customer Lifetime Value (LTV)
LTV is the total profit you earn from a customer over time.
Why it matters: A high LTV means you’re retaining customers who bring in good revenue.
Bonus: Compare LTV with CAC to see if you’re spending too much to acquire each customer.
9. Churn Rate
Churn shows how many customers leave your service over time.
Why it matters: High churn means customers aren’t satisfied or don’t see value.
Fix it: Improve onboarding, customer support, or product experience.
10. Net Promoter Score (NPS)
This measures how likely your customers are to recommend your business.
Why it matters: A high score means happy customers and more referrals.
Ask this question: “On a scale of 0–10, how likely are you to recommend us?”
Engagement Metrics: See customer behavior
These metrics help you understand how users interact with your product or service.
11. Monthly Active Users (MAU)
MAU counts how many unique users engage with your product in a month.
Why it matters: It shows how many people find value in what you offer.
Track it: Weekly and monthly to watch user growth.
12. Adoption Rate
This shows how quickly new users start using your service.
Formula: Active users ÷ Signups × 100
Why it matters: A high adoption rate means your product is easy to start using.
13. Activation Rate
This is the percentage of users who complete a key action after signing up.
Why does it matter: Low activation? Users may need more guidance or motivation.
Improve it: Use onboarding tutorials or emails.
14. Retention Rate
Retention rate is how many customers stick with your service over time.
Why it matters: Loyal users = more revenue and lower costs.
Boost it: Keep engaging customers through support and updates.
15. Lead-to-Customer Conversion Rate
This shows how well you turn leads into paying customers.
Why it matters: It tells you if your marketing and sales are working well together.
Improve it: Align sales and marketing for smoother handoffs.
Growth Metrics: Watch how fast you scale
These metrics reveal how your business is expanding over time.
16. Deferred Revenue
This is revenue you’ve received but haven’t delivered the product/service for yet.
Why it matters: It’s money in the bank, but not yet earned.
Tip: Track it to avoid overestimating your current income.
17. Total Addressable Market (TAM)
TAM is the total demand for your product or service.
Why it matters: It shows how big your market is — and how far you can grow.
Pro tip: Investors love TAM because it shows long-term potential.
18. Compound Monthly Growth Rate (CMGR)
CMGR shows how fast your business is growing month over month.
Formula: ((Final Value / Initial Value) ^ (1 ÷ Number of Months)) – 1
Why it matters: Growth trends help you plan for the future.
19. Viral Coefficient
This tracks how many new users each existing user brings in.
Why it matters: A score over 1 means your growth is multiplying.
Boost it: Encourage referrals, sharing, and incentives.
How to choose your North Star Metric?
Your North Star Metric is the one number that matters most. It depends on your business model and stage of growth.
Pre-launch: Focus on learning from user feedback.
Early stage: Track signups, MAU, and NPS.
Growth stage: Focus on MRR, LTV, and churn.
Stick with one metric that aligns your entire team. As your startup evolves, feel free to update it, but keep everyone focused on the same goal.
