The **Annual Marketing Cost Calculator** determines the critical Customer Lifetime Value (CLV) to Customer Acquisition Cost (CAC) ratio, a key metric for evaluating marketing efficiency and sustainability.
Annual Marketing Cost Calculator
Calculation Breakdown
Annual Marketing Cost Calculator Formula:
The CLV:CAC Ratio relies on two primary component calculations:
1. Customer Lifetime Value (CLV) = Monthly Revenue per Customer × (1 / Churn Rate) × Gross Margin
2. Customer Acquisition Cost (CAC) = Total Monthly Marketing & Sales Spend / New Customers Acquired
3. CLV:CAC Ratio = CLV / CAC

Variables Explained:
- Monthly Revenue per Customer (MRPC): The average revenue you generate from a single customer each month.
- Monthly Customer Churn Rate (%): The percentage of customers who stop being customers in a given month. Expressed as a percentage (e.g., 5 for 5%).
- Gross Margin (%): The percentage of revenue left after subtracting the Cost of Goods Sold (COGS). Expressed as a percentage.
- Total Monthly Marketing & Sales Spend (TMS): The total monetary resources invested monthly to attract new customers.
- New Customers Acquired this Month (NCA): The number of paying customers gained within the same month as the marketing spend.

What is an Annual Marketing Cost Calculator?
The Annual Marketing Cost Calculator, focusing on the CLV:CAC Ratio, is arguably the most vital tool in a marketing budget analysis. It shifts the focus from simple cost tracking to **profitability evaluation**. The ratio answers a fundamental question: For every dollar we spend acquiring a customer, how much value do we expect to earn back over their lifetime? A healthy ratio often sits around 3:1 (CLV is three times CAC), indicating a sustainable and scalable business model.
Understanding this metric helps businesses make strategic decisions about scaling their advertising, optimizing their sales funnel, and adjusting product pricing. A ratio that is too low (e.g., 1:1 or less) suggests you are losing money on every customer, requiring a change in either acquisition cost (CAC) or product value (CLV). A ratio that is too high (e.g., 5:1 or more) might indicate that the business is being too conservative with its marketing spend and could grow faster by investing more.
How to Calculate CLV:CAC Ratio (Example):
Let’s use the default values to walk through the calculation:
- Calculate Customer Lifetime Value (CLV):
- Monthly Revenue: $50
- Monthly Churn Rate: 5% (0.05)
- Gross Margin: 70% (0.70)
- Time = 1 / 0.05 = 20 months (Average Customer Lifetime)
- CLV = $50 × 20 × 0.70 = $700.00
- Calculate Customer Acquisition Cost (CAC):
- Monthly Spend: $5,000
- New Customers: 100
- CAC = $5,000 / 100 = $50.00
- Calculate the CLV:CAC Ratio:
- Ratio = $700.00 / $50.00 = 14:1
Frequently Asked Questions (FAQ):
Most SaaS and subscription businesses aim for a ratio of 3:1. A 3:1 ratio suggests that the customer’s lifetime value is three times the cost to acquire them, providing a healthy margin for growth and overhead.
The Churn Rate directly determines the average customer lifetime (1 / Churn Rate). If churn is high, the lifetime is short, drastically reducing the Customer Lifetime Value (CLV) and, consequently, the overall ratio.
For most businesses, calculating this metric monthly or quarterly is sufficient. It allows enough time for marketing campaigns to generate statistically significant results and for data to stabilize.
Yes, comprehensive CAC must include both Marketing and Sales expenses (salaries, tools, overhead) necessary to acquire the new customers during the period measured.
