Core capabilities built into ChurnLtv Studio
Calculating LTV as ARPA / Churn ignores COGS, fulfillment, and gateway fees. Our engine multiplies by net contribution margin so your LTV:CAC ratio reflects real cash.
Even a 4.0x LTV:CAC ratio can bankrupt a growing brand if CAC payback takes 14 months. Track exact payback months across every subscription plan.
Reducing monthly subscriber churn from 8% to 5% increases average tenure from 12.5 months to 20 months (+60% LTV surge without spending a dime more on ads).
Cloud analytics apps require read access to your Stripe or Shopify customer billing records. Run full cohort LTV audits locally in your browser.
Zero configuration, zero cloud server dependencies, instant execution.
Paste your subscription tiers, monthly recurring revenue per user (ARPA), landed gross margin percentage, monthly churn rate, and acquisition CAC.
Instantly calculate average subscriber lifespan (1 / Churn), gross-margin adjusted LTV, LTV:CAC ratio, and exact months to recover CAC.
Drag the churn reduction slider to see how cutting monthly churn by 1%–3% compounds net LTV, and export board-ready cohort schedules.

Multiply your monthly Average Revenue Per Account (ARPA) by your Gross Margin percentage (after COGS, shipping, and gateway fees) to get Monthly Gross Contribution, then divide by your monthly decimal churn rate: (ARPA * Gross Margin %) / Monthly Churn Rate.
A 3:1 Gross-Margin LTV:CAC ratio ensures that 33% of customer lifetime contribution covers acquisition cost, leaving 67% to cover operating overhead and generate healthy net profit.
Divide your Customer Acquisition Cost (CAC) by your Monthly Gross Contribution per subscriber (ARPA * Gross Margin %). For DTC and boot-strapped brands, a payback period under 3 to 4 months keeps cash flow healthy.
Because churn sits in the denominator of the LTV formula, reductions have a non-linear compounding effect. Dropping monthly churn from 6% to 4% increases average customer lifespan from 16.7 months to 25.0 months—a +50% surge in net LTV.
