# Startup Runway, Burn Rate & Default Alive Calculator

Calculate how many months of cash runway your startup has left and check whether you are Default Alive or Default Dead.

## Formula & Methodology
`Net Burn = Monthly Expenses - MRR · Runway models monthly cash draw against compounding MRR`

**Default Benchmark Result (Growth-Adjusted Cash Runway):** Default Alive (∞)
With $18,000 monthly revenue compounding at 9.0%/mo against $48,000 opex, your startup reaches cash-flow break-even before exhausting $450,000 in reserves (Default Alive).

## Default Inputs
- **Cash Balance in Bank ($)** (`a`, currency): Default = `450000`
- **Current Monthly Revenue (MRR $)** (`b`, currency): Default = `18000`
- **Monthly Operating Expenses ($)** (`c`, currency): Default = `48000`
- **Monthly Revenue Growth Rate (%)** (`d`, percent): Default = `9`

## Sample Output Metrics
- **Current Net Burn / Mo:** $30,000
- **Static Zero-Growth Runway:** 15.0 mos
- **Growth-Adjusted Runway:** Default Alive (∞)
- ** Burn Multiple:** 18.52x
