Startup Metrics: 17 Important KPIs You Should Track

1. Monthly Recurring Revenue (MRR)

What is MRR?

MRR is the consistent, predictable revenue a business generates monthly from subscriptions or recurring payments.

Why is MRR Important?

MRR is a foundational metric for subscription-based startups. It reflects financial stability, growth, and the effectiveness of your customer acquisition strategies.

How to Calculate MRR

Multiply the total number of active subscriptions by the average revenue per account (ARPA).

Formula:

MRR = Total subscriptions × ARPA

1. Upsell and Cross-Sell: Offer premium plans or add-ons to existing customers.
2. Reduce Churn: Improve customer support and retention efforts.
3. Acquire More Subscribers: Refine your marketing strategies to target high-value customers.

2. Customer Acquisition Cost (CAC)

What is CAC?

CAC measures the average cost of acquiring a new customer, including marketing and sales expenses.

Why is CAC Important?

A low CAC ensures profitability and scalability, helping startups grow sustainably.

How to Calculate CAC

Divide total acquisition costs (marketing + sales) by the number of new customers acquired.

Formula:

CAC = Total acquisition costs ÷ Number of new customers

How to Improve CAC

1. Focus on Inbound Marketing: Use content marketing, SEO, and referrals to lower acquisition costs.
2. Optimize Ad Spend: Test campaigns and focus on high-performing channels.
3. Shorten the Sales Cycle: Streamline processes to convert leads faster.

3. Customer Lifetime Value (CLV)

What is CLV?

CLV measures the total revenue a customer is expected to generate during their relationship with your startup.

Why is CLV Important?

A high CLV means customers are loyal and generate long-term value, justifying acquisition costs.

How to Calculate CLV

Multiply the average revenue per user (ARPU) by the average customer lifespan.

Formula:

CLV = ARPU × Average customer lifespan

How to Improve CLV

1. Enhance Customer Retention: Offer excellent support and personalized experiences.

What is the Payback Period?

The payback period measures how long it takes to recover the cost of acquiring a customer (CAC) through revenue generated by that customer.

Why is the Payback Period Important?

This metric ensures that your acquisition costs are sustainable. A shorter payback period means you can reinvest revenue sooner.

How to Calculate Payback Period

Divide the CAC by the average monthly revenue generated per customer.

Formula:

Payback period = CAC ÷ Monthly revenue per customer

How to Improve the Payback Period

1. Increase Monthly Revenue: Upsell or cross-sell higher-value products or services.
