fin.churn-ltv-impact Calculator
Calculates the LTV impact of a given churn rate on customer lifetime and lifetime value. Reducing monthly churn from 3% to 2% extends average customer lifetime from 33 to 50 months — the compounding effect makes churn reduction extremely high-leverage.
Inputs
Monthly Churn
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Arpu Monthly
Reference formula or conversion factor shown for context.
Gross Margin
Profit as a percentage of revenue. Margin % is always lower than markup % — a $5 profit on a $15 selling price is 33% margin but 50% markup.
Cac
Reference formula or conversion factor shown for context.
Results
customer lifetime (months)
The result expressed in months. Divide by 12 to convert to years.
LTV
LTV (customer lifetime value) -- total revenue expected from a customer over their entire relationship. Compare to CAC for unit economics.
LTV:CAC
LTV (customer lifetime value) -- total revenue expected from a customer over their entire relationship. Compare to CAC for unit economics.
annual churn
The result expressed on a per-year basis.
benchmark LTV:CAC
Reference value for comparison — the industry standard, historical average, or target that this result is measured against.
payback period
Time to recover the initial investment from cumulative cash flows. Most firms target 2–5 years. Does not account for the time value of money — use discounted payback for rigour.
