About Subscription Revenue Calculator

Subscription business metrics: Monthly Recurring Revenue (MRR) = sum of all active monthly subscription values; Annual Recurring Revenue (ARR) = MRR x 12; Customer Lifetime Value (LTV) = ARPU / Monthly Churn Rate; Customer Acquisition Cost (CAC) = total sales and marketing spend / new customers acquired. Healthy SaaS: LTV:CAC ratio above 3:1; CAC payback period under 12 months.

Churn rate dramatically affects LTV. Monthly churn of 5% means average customer lifetime of 20 months; 2% churn means 50 months. Reducing churn from 5% to 2% triples LTV without acquiring a single new customer. Net Revenue Retention (NRR) above 100% means existing customers generate more revenue over time even with some churn. Annual billing typically reduces churn by 30-40% and improves cash flow predictability. Optimise for NRR first, then new customer growth.

Frequently Asked Questions

Annual Recurring Revenue equals Monthly Recurring Revenue (MRR) multiplied by 12. MRR is the sum of every active monthly subscription value; ARR simply annualises that figure. This calculator shows your Annual Total Cost the same way — per-seat price × number of seats × 12 for monthly billing.
Churn has an outsized effect on LTV, which is calculated as ARPU divided by monthly churn rate. At 5% monthly churn the average customer lifetime is about 20 months; at 2% churn it stretches to 50 months. Reducing churn from 5% to 2% roughly triples lifetime value without acquiring a single new customer, which is why retention work is usually a better investment than new-customer growth alone.
Aim for a Customer Lifetime Value to Customer Acquisition Cost (LTV:CAC) ratio above 3:1, with a CAC payback period under 12 months. LTV:CAC below 3:1 usually means you are spending too much to acquire customers relative to what they are worth over their lifetime; well above 5:1 can sometimes mean you are under-investing in growth.
Annual billing typically saves 15–25% compared to monthly billing on the same subscription, and this calculator shows the exact rupee savings and percentage discount for your seat count. Beyond the direct discount, annual billing also tends to reduce customer churn by 30–40% and improves cash flow predictability for the vendor, which is often reflected in the discount they offer.
