Do it in order
Recommended Workflow
- 1
Pick the decision first
Choose the metric that answers the question you actually have. More numbers is not more clarity.
- 2
Use margin, not just revenue
Value and growth mean more when they account for the cost of delivering it.
- 3
Compare like with like
Match periods and cohorts so growth is real, not a seasonal illusion.
- 4
Turn the number into an action
A metric that does not change a decision is a vanity metric. Decide what you will do differently.

Metrics That Matter
- Customer lifetime value
- Total margin a customer produces over the relationship. Use margin, not revenue, for an honest figure.
- LTV to CAC ratio
- Customer value against the cost to acquire them. Around 3 to 1 is a common healthy target, but your context decides.
- QoQ growth
- Short-term momentum between quarters. Sensitive to seasonality, so read it with care.
- YoY growth
- Growth over the same period last year, which removes most seasonality and shows the real trend.
Avoid these
Common Mistakes
- Using revenue LTV when margin LTV is the honest number.
- Reading seasonal QoQ swings as a trend.
- Chasing a 3 to 1 LTV to CAC rule without questioning your own margins.
- Reporting growth off a tiny base so the percentage exaggerates the story.
Questions
Category FAQs
Are these analytics calculators free?
Yes. All of them are free with no sign up, and the formulas are shown so you can check the math.
Should LTV use revenue or margin?
Margin. Revenue LTV overstates value because it ignores the cost of serving the customer. Margin LTV is the number to base spending on.
What is a healthy LTV to CAC ratio?
Around 3 to 1 is a common target, meaning a customer is worth roughly three times what it costs to acquire them. Very high ratios can signal underspending on growth.
When should I use YoY instead of QoQ?
Use YoY when seasonality matters, since it compares the same period last year. Use QoQ to watch short-term momentum.
Do the tools store my numbers?
