Build a consistent SaaS operating snapshot

Use this dashboard to place recurring revenue, account economics, retention, and acquisition cost on one monthly scenario. Supply MRR and CAC in dollars, active accounts as a positive whole-number count, and gross margin, monthly churn, and expansion as percentages. MRR and active accounts must describe the same month and customer population.

Metrics included

The supported product-defined relationships are:

  • ARR = 12 × MRR and ARPA = MRR / active accounts.
  • Monthly gross profit per account is ARPA × gross margin.
  • Gross-profit LTV is that monthly amount divided by monthly churn.
  • LTV:CAC = LTV / CAC; CAC payback is CAC / monthly gross profit per account.
  • Net revenue retention is 100% - churn + expansion; logo retention is 100% - churn.

These are a simplified scenario, not a universal SaaS reporting standard. Churn and expansion are entered as direct monthly rates; no cohort weighting, contraction, reactivation, annualization of retention, acquisition timing, or cash-flow discounting is added.

Reproduce the default dashboard

For $60,000 MRR, 400 accounts, 75% gross margin, 4% monthly churn, 1.5% expansion, and $800 CAC: ARPA is $150, ARR is $720,000, gross-profit LTV is $2,812.50, LTV:CAC is 3.52:1, and payback is 7.11 months. NRR is 97.5% and logo retention is 96%. Recheck the dashboard after substituting a segment-specific account count and churn rate; the side-by-side change shows which assumption drives the result.

At least one active account and positive churn are required. Percentages are limited to 0%–100%, with churn no lower than 0.01%. Zero CAC leaves LTV:CAC unavailable, and zero monthly gross profit leaves payback unavailable rather than implying a meaningful zero. Negative, blank, unknown-option, or invalid numeric inputs are rejected.

Use the SaaS LTV calculator to examine dollar expansion separately. Treat all outputs as internal scenario estimates, not valuation, investment, or accounting advice.

Align the account and revenue snapshot

Use MRR and active-account figures from the same reporting cutoff and save the margin, churn, expansion, and CAC assumptions. Compare a changed retention scenario without also changing the customer-count basis. This keeps an input-based metrics illustration separate from a verified cohort analysis.

Frequently asked questions

What SaaS metrics does this calculator calculate?

It calculates ARR, ARPA, gross-profit LTV, LTV to CAC, CAC payback months, net revenue retention, and logo retention from one monthly snapshot. The primary result remains current MRR, while the supporting metrics turn that revenue into a dashboard for acquisition, retention, margin, and expansion quality.

Why does the LTV calculation use gross margin?

Gross margin is an entered percentage that this house model applies to ARPA before dividing by churn. The calculator does not define which cost categories belong in that percentage or infer cash availability from the result.

How is net revenue retention different from logo retention?

Logo retention is 100% minus the entered churn rate. Net revenue retention is 100% minus the entered churn rate plus the entered expansion rate. The calculator reports both arithmetic results without applying a performance benchmark.

Why does payback show a warning even when LTV is high?

The calculator reports payback as CAC divided by modeled monthly gross profit per account. It applies no benchmark or warning threshold, so the displayed duration should be read only as the result of the entered scenario.
