Accuracy and assumptions
Questions about estimate quality, limitations and interpretation.
Is this calculator accurate for every business?
It provides an estimate based on averages. Results may differ if your traffic, pricing or retention varies across customer groups.
Does the calculator measure profit?
No. It estimates revenue, not profit, because it does not subtract costs, refunds, fees or overhead.
Why can results change a lot with small input changes?
Because conversion rates compound through the funnel and customer lifetime value multiplies several inputs together.
Does monthly cohort lifetime revenue mean immediate revenue?
No. It represents the expected future revenue from customers acquired in one month over their full lifespan.
Inputs and results
Questions about choosing inputs and avoiding common data issues.
Should I use average order value or average revenue per customer?
Use average order value if you are also entering purchase frequency. Otherwise you may double count repeat purchases.
What if my customer lifespan is less than one year?
You can enter a fractional year, such as 0.5, if that better reflects average customer retention.
Can I use this calculator for subscription businesses?
Yes. You can approximate recurring revenue by using the average payment amount and the number of payments per year.
What if conversion rates differ by traffic source?
It is often better to calculate each source separately, because a single average may hide large differences in quality and value.
