Frequently Asked Questions

What is a good LTV:CAC ratio?

A 3:1 ratio is considered healthy — your customer is worth 3x what you spent to acquire them. Below 1:1 means you are losing money. Above 5:1 may mean you are underinvesting in growth.

How is CAC calculated?

CAC = (Total Marketing Spend + Total Sales Spend) / Number of New Customers Acquired. Include all costs: ads, salaries, tools, content creation, commissions, and overhead.

What is a good marketing ROI?

A 5:1 ratio (500% ROI) is generally considered strong, meaning $5 in revenue for every $1 spent. Digital marketing averages 2:1 to 5:1, while email marketing can achieve 10:1 or higher.

What is the difference between ROI and ROAS?

ROI measures profitability as a percentage: (Revenue - Cost) / Cost × 100. ROAS (Return on Ad Spend) measures revenue per dollar spent: Revenue / Cost. A $5,000 campaign generating $25,000 has 400% ROI and 5:1 ROAS.
