Projects customer lifetime value using average order value, purchase frequency, gross margin, and estimated customer lifespan in months. SaaS founders and e-commerce operators use LTV to determine acquisition budgets, segment high-value customers, and forecast recurring revenue.

Calculate Customer Lifetime Value using ARPU and churn rate. Understand how much revenue each customer generates over their relationship. Everything runs locally in your browser — nothing is uploaded.
Calculate Monthly Recurring Revenue from customer count and average revenue per account (ARPA), with new, expansion, churned, and contraction MRR broken out so net growth is visible. Example: 120 customers at $49 ARPA = $5,880 MRR. Everything runs locally in your browser — nothing is uploaded.
Models subscription revenue across tiers (free, monthly, annual) with inputs for conversion rate, churn, customer count, and average revenue. Everything runs locally in your browser — nothing is uploaded.
Calculates gross margin percentage, markup percentage, cost, and selling price from any two known variables — perfect for retail pricing, wholesale negotiations, and e-commerce product listing optimization where you need to work backwards from a target margin.
Computes gross profit, net profit, and margin percentages from revenue and cost inputs. Small-business owners use it to price products, evaluate supplier deals, and ensure healthy margins across their product lines.
LTV = ARPA × gross margin × average lifetime in months. Example: $50 ARPA × 80% margin × 20 months = $800 LTV. E-commerce variant swaps ARPA for average order value × purchase frequency.
3:1 or higher — $800 LTV supports up to ~$267 CAC. Below 3:1 you're overpaying for growth; above 5:1 you're likely under-spending and growing slower than you could.
Average hides everything: enterprise cohorts often show 5× the LTV of self-serve. Segment by plan, channel, and signup month before setting budgets — one blended number misprices every channel.
Lifetime ≈ 1 ÷ monthly churn rate: 5% monthly churn implies ~20 months average life. Cut churn from 5% to 3% and the same $50×80% base jumps from $800 to ~$1,333 LTV.
Use gross margin (revenue minus cost of delivery), not revenue. A $50 plan at 80% margin contributes $40/month, not $50 — forgetting margin overstates LTV by 25% here.
