How to use this tool
Replace the example values with your own inputs. Results update as you type. Keep your measurement period and definitions consistent, then use the result to inform the next question in your advertising review.
The formula
Revenue LTV = order value × annual orders × years. Contribution LTV = revenue LTV × margin. LTV:CAC = contribution LTV ÷ CAC.
Worked example
80 per order, four orders per year and three years gives 960 revenue LTV. At 40% margin, contribution LTV is 384.
What the result can tell you
This simple scenario assumes constant purchase frequency and margin. It does not discount future cash flows or model a retention curve.
