SaaS LTV Calculator
Calculate SaaS Customer Lifetime Value (LTV) adjusted for gross margins and churn, and find target CAC.
What is the SaaS LTV Calculator?
SaaS Lifetime Value (LTV) calculation projects the aggregate net gross profit generated from a subscription customer over their entire commercial relationship. It divides Average Revenue Per Account (ARPA) multiplied by gross margin percentage by the customer churn rate across defined subscription billing intervals. This equips software executives with vital unit economic metrics to set sustainable customer acquisition spending limits and optimize sales channel investments.
The SaaS LTV Calculator computes margin-adjusted Customer Lifetime Value (LTV) to help software founders and finance leaders establish sustainable customer acquisition budgets and evaluate unit economics.
