SaaS performance metrics

Direct answer

For this review, group SaaS metrics by growth, retention, efficiency, and capital discipline.

Why this question comes up

Founders track ARR/MRR but struggle with CAC, LTV, churn, NRR, burn multiple, and which metrics investors care about. This guide turns that concern into a review that can be repeated with a defined period, consistent inputs, and a visible trail back to the records.

Records to gather

• MRR or ARR by customer by month, with movement categorised
• New, expansion, contraction, and churned revenue separately
• Customer counts by cohort
• Gross margin including hosting, support, and success costs
• Sales and marketing spend by period

Review workflow

1. Break MRR movement into its four components. New, expansion, contraction, and churn. A flat MRR month can be strong growth offset by heavy churn, or stagnation — and only the breakdown distinguishes them.
2. Report gross and net retention separately. Gross shows loss honestly; net includes expansion and can conceal a churn problem behind a few large upsells.
3. Do not present ARR as revenue. ARR is a forward run-rate; recognised revenue is a historical result. Mixing them in the same report misleads readers.
4. Compute gross margin properly. Hosting, support, customer success, and third-party service costs belong in cost of revenue. Excluding them inflates every downstream metric.
5. Use cohorts for retention. Blended figures hide deterioration by up to a year.
6. State the definition of every metric. MRR treatment of annual contracts, discounts, and one-off fees varies between companies and produces non-comparable numbers.

What a useful answer should include

• MRR movement split into new, expansion, contraction, and churn
• Gross and net revenue retention, both shown
• ARR and recognised revenue clearly distinguished
• Gross margin with cost of revenue components listed
• Cohort-based retention rather than blended
• Explicit definitions, especially the MRR treatment of annual deals

Common failure modes

• Reporting net MRR growth only. It hides whether churn or acquisition is driving the result.
• Leading with net retention. A handful of expansions can mask broad customer loss.
• ARR presented as revenue. Different measures; investors and lenders read them differently.
• Thin cost of revenue. Omitting support and success costs inflates gross margin and everything built on it.
