Built for subscription commerce
These calculators use the standard subscription formulas — LTV ≈ price ÷ churn, MRR = subscribers × price, ARR = MRR × 12 — so you can sanity-check your numbers in seconds. When you’re ready to track them automatically from live data, RecurX reports MRR, ARR, churn, LTV, and cohort retention from your Shopify store, and recovers failed payments with built-in dunning.
