Marketing Metrics Explained
Understanding these key performance indicators helps you optimize campaign spend and maximize returns.
ROI (Return on Investment)
The percentage return: (Revenue - Spend) / Spend x 100. Above 0% means profit; 100%+ is excellent.
ROAS (Return on Ad Spend)
Revenue divided by ad spend. A ROAS of 4x means you earn $4 for every $1 spent. Above 3x is generally strong.
CPL (Cost Per Lead)
How much each lead costs you. Lower is better. Benchmarks vary by industry: $20-$50 for B2C, $50-$200 for B2B.
CPA (Cost Per Acquisition)
The cost to acquire one paying customer. Should always be significantly lower than your customer lifetime value.
Conversion Rate
The percentage of leads that become customers. B2B averages 2-5%, while B2C can range from 1-10%.
LTV:CAC Ratio
Lifetime Value vs Customer Acquisition Cost. 3:1 is healthy, 5:1+ is excellent. Below 1:1 means you're losing money.

Frequently Asked Questions
What's the difference between ROI and ROAS?
ROI measures net profit as a percentage of investment: (Revenue - Cost) / Cost. ROAS measures gross revenue per dollar spent: Revenue / Cost. ROAS is always a higher number since it doesn't subtract the cost.
What's a good LTV:CAC ratio?
3:1 is considered healthy — you earn $3 for every $1 spent acquiring a customer. Below 1:1 means you're losing money on each customer. Above 5:1 could mean you're under-investing in growth.
How do I calculate Customer Lifetime Value?
A simple formula: Average Purchase Value x Purchase Frequency x Average Customer Lifespan. For subscriptions: Monthly Revenue per Customer x Average Months as Customer.
Should I track ROI per channel?
Absolutely. Different channels have very different cost structures and conversion rates. Track ROI separately for each channel to know where to allocate budget for maximum returns.
