Answers: how much revenue churn costs, what you save by cutting churn, and how LTV changes.

| Segment | Monthly churn | Annual logo churn | Notes |
|---|---|---|---|
| Enterprise SaaS (>$100K ACV) | < 1% | 5 – 10% | Example: 1% → 0.5% on $500K MRR saves $27.6K over 12mo |
| Mid-market ($10K – $100K ACV) | 1 – 3% | 12 – 30% | Default 5% → 3% is SMB-style; mid-market often starts lower |
| SMB SaaS (< $10K ACV) | 3 – 7% | 30 – 60% | Default $100K MRR at 5% monthly = $60K annual churn cost |
| Consumer subscription | 5 – 10% | 50 – 70% | 8% → 6% on $50K MRR saves $5.4K over 12mo in this model |
| Metric | Formula | Example |
|---|---|---|
| Gross revenue churn | (Churned MRR + Downgrades) ÷ Starting MRR | $5K/mo lost on $100K MRR = 5% gross |
| Net revenue retention (NRR) | (Start + Expansion − Churn − Contraction) ÷ Start | 103% if +$10K expansion, −$5K churn |
| Logo churn | Customers lost ÷ Customers at period start | 25 of 500 = 5% monthly logo churn |
| This calculator | Compound MRR: MRR × (1 − r)^months | 12mo at 5% → 54% MRR retained ($54K of $100K) |
| Monthly churn | Avg lifespan | LTV | vs 5% default |
|---|---|---|---|
| 10% | 10 | $2,000 | 50% of 5% LTV |
| 5% | 20 | $4,000 | Default current churn |
| 3% | 33 | $6,667 | Default target — +67% vs 5% |
| 1% | 100 | $20,000 | 5× LTV vs 5% churn |
Monthly churned revenue = MRR × (Churn % ÷ 100)MRR(month t) = MRR(0) × (1 − churn)^tRevenue saved = MRR loss(current churn) − MRR loss(target churn)LTV ≈ ARPU ÷ (Monthly churn % ÷ 100)Revenue saved
