Personalized Actionable Insights
The LTV:CAC ratio is a primary health metric for subscription businesses. A ratio below 3x indicates unsustainable acquisition costs, while a ratio above 5x suggests you might be underinvesting in growth.
Optimize LTV:CAC ratio: Target an LTV:CAC ratio of 3x or higher to ensure long-term profitability and sustainable scaling.
Shorten payback periods: Focus on reducing your CAC payback period to under 12 months to improve company cash flow.
Diversify marketing channels: Balance high-cost paid ads with organic channels like SEO and content marketing to reduce overall CAC.
Understand the logic under the hood. Here is the formula and exact variable mappings utilized by the Customer Acquisition Cost (CAC) & LTV Studio to compile results.
CAC = (Ad Spend + Salaries + Fees) / Acquired | LTV = ARPU / Churn%
Customer Acquisition Cost is the total sales and marketing spend divided by customers acquired. Customer Lifetime Value is ARPU divided by the monthly churn rate. The LTV:CAC ratio evaluates overall unit economics viability.
Direct expenditures on paid marketing campaigns (Google Ads, Facebook, etc.).
Employee salaries allocated to marketing and sales staff.
Total new paying customers gained during the monthly period.
Average monthly revenue generated per paying user.
Our Customer Acquisition Cost (CAC) & LTV Studio integrates corporate accounting protocols (e.g. gross margin calculations, GST taxation equations) to output commercial business ratios with precise step-by-step example steps.
See the calculation in action. Below is a step-by-step mathematical example using default parameters to demonstrate how values are processed and generated.
Total monthly marketing spend is $5,000 ad spend + $1,500 software fees + $3,000 salaries = $9,500.
Acquiring 200 customers yields CAC of $9,500 / 200 = $47.50.
With ARPU of $60 and 4% churn, the customer LTV is $60 / 0.04 = $1,500.
The LTV:CAC ratio is $1,500 / $47.50 = 31.6x, indicating exceptionally profitable marketing and high viability!
