# Cybersecurity SaaS Churn Rate & Net Revenue Retention Calculator

Quantify how reducing monthly churn by 1–2% compounds ARR and enterprise valuation for your Cybersecurity SaaS company.

## Formula & Methodology
`Annualized Churn = 1 - (1 - MonthlyChurn)^12 · Retained LTV = (ARPU × Margin%) ÷ MonthlyChurn`

**Default Benchmark Result (Retention-Adjusted Customer LTV):** 42.34x LTV:CAC
Each customer generates $37,683 in gross-margin LTV over an average 111.1-month lifespan, yielding a 42.34:1 LTV:CAC ratio and 2.6-month CAC payback.

## Default Inputs
- **Average Monthly Revenue Per Account ($)** (`a`, currency): Default = `399`
- **Gross Margin (%)** (`b`, percent): Default = `85`
- **Target Monthly Churn Rate (%)** (`c`, percent): Default = `0.8999999999999999`
- **Blended Acquisition Cost (CAC)** (`d`, currency): Default = `890`

## Sample Output Metrics
- **Customer Lifetime Value (LTV):** $37,683
- **LTV : CAC Ratio:** 42.34 : 1
- **CAC Payback Period:** 2.6 mos
- **Monthly Gross Contribution:** $339.15
