How to use this SaaS metrics calculator
Enter your number of paying customers, average monthly price, monthly churn rate, expansion revenue rate, and customer acquisition cost. The calculator instantly computes MRR, ARR, net revenue retention (NRR), customer lifetime value (LTV), LTV:CAC ratio, and payback period.
Each metric is color-coded against healthy early-stage SaaS benchmarks: green for healthy, amber for needs attention, and red for critical. This gives you an instant health check without needing to look up industry standards.
Key SaaS metrics explained
MRR (Monthly Recurring Revenue) is the predictable revenue your business generates each month from subscriptions. ARR is simply MRR × 12 — it's the annualized view investors and founders use to benchmark growth.
NRR (Net Revenue Retention) measures how much revenue you keep and grow from existing customers, including expansion but excluding new sales. Above 100% means your existing base is growing even without new customers — a strong signal of product-market fit.
LTV:CAC ratio tells you whether your customers are worth more than they cost to acquire. Below 1:1 means you're losing money on every customer. The industry target is 3:1 or better — meaning each customer generates 3× the cost of acquiring them.
If you're monetizing with upgrades or add-ons, keep an eye on ARPPU alongside ARPU. And if your margins feel compressed, break out your direct delivery costs in COGS before changing pricing.
Healthy SaaS benchmarks by stage
Where your metrics should be depends on your stage. Here are typical ranges for early-stage and scaling SaaS products:
| Metric | Healthy | Warning | Critical |
|---|---|---|---|
| Monthly churn | < 5% | 5–8% | > 8% |
| NRR | > 100% | 90–100% | < 90% |
| LTV:CAC | > 3:1 | 1.5–3:1 | < 1.5:1 |
| Payback period | < 12 mo | 12–18 mo | > 18 mo |
