CAC and LTV get thrown around constantly, but most teams eyeball them rather than calculate them properly — and a CAC that ignores fully-loaded S&M spend, or an LTV that ignores gross margin, will flatter numbers that don't survive board scrutiny. This calculator uses the same subscription-economics formulas investors use: gross-margin-adjusted LTV, a churn-derived customer lifetime, and a payback period benchmarked against the 12-month standard for efficient SaaS and B2B growth. Enter your spend, customer, revenue, margin, and churn numbers below to see where you actually stand.
Enter total fully-loaded Sales & Marketing spend and the number of new customers acquired in that same period — the tool divides these to get CAC. Then enter average annual revenue per customer, gross margin %, and annual churn rate — it uses these to derive LTV (gross-margin-adjusted, divided by churn) and the CAC payback period (CAC divided by monthly gross profit per customer). The output shows all four headline metrics, bar comparisons against standard benchmarks, a status table, and a verdict with specific recommendations for whichever metric is weak.
Tools like this describe good practice. They can't tell you which of your reps actually have the skill, or in what order to build it. That's what The Mastery Standard does: 27 frameworks, 54 competencies, every rubric cell written, every assessment human-signed-off.
