1. Customer Acquisition Cost (CAC): The Price of Growth 💸

Definition: CAC measures how much it costs to acquire a new customer, including all sales and marketing expenses.

Why It’s Important:
Knowing your CAC ensures you’re not overspending on customer acquisition. It's vital to balance CAC with the revenue and profit you’ll earn from customers over their lifecycle.

​

Example:
If you spend £10,000 on marketing and acquire 100 customers in a month:

Insights and Tips:

• Lower your CAC by improving customer targeting, investing in organic channels, or optimizing your ad spend.

• Always compare CAC with Customer Lifetime Value (CLV) to ensure profitability.

• Compare CAC across different channels and target those where you have lower CAC (e.g. if you’re targeting professionals for providing job-related services, LinkedIn may be better than Instagram)

🔗 Benchmark: For industry-specific CAC insights, refer to Shopify’s CAC by Industry Guide.

2. Customer Lifetime Value (CLV): Maximising Revenue from Each Customer 💎

Definition:
CLV estimates the total revenue a business can expect from a single customer over their lifetime.

Why It’s Important:
CLV helps you determine how much you can afford to spend on acquiring customers while remaining profitable.

How to Calculate:

Example:

• Average monthly spend per customer = £50

• Average customer lifespan = 2 years (24 months)

Insights and Tips:
✅ Higher CLV means you can afford a higher CAC, which allows more aggressive marketing strategies.
✅ Increase CLV by improving customer satisfaction, offering loyalty programs, or adding new products/services.
✅ Compare CLV with CAC—a CLV-to-CAC ratio of at least 3:1 is a good benchmark.

🔗 Benchmark: Explore industry-specific CLV benchmarks at HubSpot’s CLV Guide.

3. Average Revenue Per User (ARPU): Revenue Efficiency Per Customer 💰

Definition:
ARPU measures the average revenue generated per customer over a specific period.

Why It’s Important:
ARPU helps evaluate pricing strategy and customer value, ensuring revenue aligns with business goals.

How to Calculate:

Example:
If your business generates £50,000 in revenue with 1,000 customers:

Insights and Tips:
✅ Increase ARPU by offering bundles, premium services, or upsells.
✅ Compare ARPU across customer segments to identify high-value customers.
✅ Track ARPU trends—a declining ARPU may indicate pricing or product positioning issues.

4. Monthly Recurring Revenue (MRR): Your Financial Anchor 📆

Definition: MRR is the predictable monthly revenue generated from subscription-based customers.

Why It’s Important:
MRR provides stability and visibility into your business’s financial health. For SaaS and subscription-based businesses, it’s the most critical revenue metric.

Example:
If you have 200 active subscribers each paying £50 per month:

Insights and Tips:

• Boost MRR by acquiring more customers, upselling to existing ones, or introducing premium tiers.

• Reducing customer churn will also preserve and grow your MRR.

5. Customer Retention Rate (CRR): Loyalty Over Acquisition 🔄

Definition: CRR is the percentage of customers who continue to do business with you over a given period.

Why It’s Important:
Retaining customers is more cost-effective than acquiring new ones. A high retention rate signals customer satisfaction and loyalty.

Example:
If you start the month with 500 customers, gain 50 new customers, and end the month with 520 customers:

Insights and Tips:

• Introduce loyalty programs, personalized offers, or better customer support to boost CRR, so it stays closer to 100%

• Add why 100% is better

• Use customer feedback surveys to understand what drives loyalty

6. Net Revenue Retention (NRR): Maximizing Existing Customers 🌱

Definition: NRR measures the percentage of recurring revenue retained from existing customers after accounting for upgrades, downgrades, and churn.

Why It’s Important:
NRR is a powerful growth indicator, showing whether your current customer base is growing or shrinking in revenue terms.

Example:

• Starting MRR: £50,000

• Expansion Revenue: £5,000

• Churned Revenue: £3,000

Insights and Tips:

• Aim for an NRR above 100% to ensure growth within your existing customer base.

• Use upselling and cross-selling strategies to increase expansion revenue.
