What is a good LTV/CAC ratio for a SaaS?
The usual industry benchmark is an LTV/CAC ratio of at least 3: the value a customer generates over their lifetime should be at least 3× their acquisition cost for the business model to be considered healthy.

Tutto su SaaS metrics dashboard — MRR, churn, NRR, LTV/CAC, Rule of 40
📋Presentazione+
This dashboard computes the growth and commercial-efficiency metrics of a SaaS business from its MRR (Monthly Recurring Revenue): ARR, monthly and annualised (compounded) churn, Net Revenue Retention (NRR), LTV (customer lifetime valued at gross margin), CAC (customer acquisition cost), LTV/CAC ratio, CAC payback period and the Rule of 40 (growth + EBITDA margin). These management benchmarks, widely used across the SaaS industry with investors and boards, are not an accounting or tax standard.
🔢 Esempio concreto
An MRR of €100,000 with 2%/month churn, an 80% gross margin and 10 new customers acquired for €12,000 of sales & marketing spend (CAC €1,200) yields an LTV of roughly €40,000 and an LTV/CAC ratio of 33 — well above the healthy threshold of 3.
📖Guida all'uso+
Come usare questo calcolatore
- 1
Enter your MRR at the start of the period, plus the expansion, contraction and churn observed over the period.
- 2
Enter your customer count at the start of the period and the new customers acquired.
- 3
Enter your gross margin (%) and the sales & marketing costs incurred over the period.
- 4
Enter your annual growth rate and EBITDA margin for the Rule of 40.
- 5
Read the verdicts against standard benchmarks (LTV/CAC ≥ 3, payback ≤ 12 months, Rule of 40 ≥ 40%).
📚Glossario+
- NRR (Net Revenue Retention)
- The share of start-of-period MRR retained after expansion (upsell), contraction (downgrade) and churn, expressed as a % — an NRR above 100% means expansion more than offsets churn.
- LTV (Lifetime Value)
- Total value generated by a customer over their lifetime, computed here as (average MRR per customer × gross margin) / monthly churn rate.
- Rule of 40
- A management benchmark whereby the sum of the annual growth rate (%) and the EBITDA margin (%) should reach at least 40% for a healthy SaaS business, whatever the balance between growth and profitability.

FAQ — SaaS metrics dashboard — MRR, churn, NRR, LTV/CAC, Rule of 40
What is a good LTV/CAC ratio for a SaaS?+
The usual industry benchmark is an LTV/CAC ratio of at least 3: the value a customer generates over their lifetime should be at least 3× their acquisition cost for the business model to be considered healthy.
How do I annualise monthly churn?+
Annualised churn is not simply monthly churn × 12: you compound monthly retention over 12 months, i.e. annualised churn = 1 − (1 − monthly churn)^12.
What is a good CAC payback?+
The usual benchmark is a CAC payback (time to recover the acquisition cost through gross margin generated) of 12 months or less, though this threshold varies with the company's maturity and funding model.
How is the Rule of 40 achieved?+
The Rule of 40 is met by combining growth and profitability: a fast-growing company (e.g. 50%) can run a negative EBITDA margin (−10%) and stay on target (40), while a mature company must offset slower growth with higher profitability.
What is the difference between MRR and ARR?+
MRR (Monthly Recurring Revenue) is monthly recurring revenue; ARR (Annual Recurring Revenue) is its annual projection (MRR × 12). ARR is the preferred metric for communicating the size of a SaaS business to investors.
