INTERACTIVE · LIVE · STANDARD FORMULASGross margin is revenue minus direct delivery costs (hosting, support attribution, payment fees), as a % of revenue. Monthly churn is the % of customers who leave each month — a 3% monthly churn = ~30% annual churn. CAC = total sales+marketing spend ÷ new customers in a period.
Standard SaaS formulas. Excludes upsell, expansion, and seasonality — model those separately.
These formulas are SaaS-standard but don't account for upsell/expansion revenue or seasonality. If your customers expand 10-20%/year (negative net revenue churn), real LTV is meaningfully higher than these formulas show — model it with a separate spreadsheet.
