Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

runway-calculator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/runway-calculator - Startup Runway Calculator

Triggers

  • When assessing how long the company can survive
  • Before fundraising to understand urgency
  • When making budget decisions (hire vs defer)
  • Monthly financial health check

Usage

/runway-calculator
/runway-calculator --cash 500000 --burn 50000 --revenue 10000
/runway-calculator --scenario                  # Multi-scenario analysis

Behavioral Flow

Phase 1: Input Collection

Gather financial data (prompt user or accept parameters):

Required:
  - Cash on hand: $[amount]
  - Monthly burn rate: $[amount] (total expenses)
  - Monthly revenue: $[amount] (if any)

Optional:
  - Revenue growth rate: [%] per month
  - Expected funding: $[amount] in [N] months
  - Planned hires: [N] people × $[cost] starting [month]

Phase 2: Calculate Base Runway

Net Burn = Monthly Burn - Monthly Revenue
Runway (months) = Cash / Net Burn

Example:
  Cash: $500,000
  Burn: $50,000/month
  Revenue: $10,000/month
  Net Burn: $40,000/month
  Runway: 12.5 months

Phase 3: Scenario Analysis

# Runway Analysis — YYYY-MM-DD

## Current Position
| Metric | Value |
|--------|-------|
| Cash on Hand | $[N] |
| Monthly Burn | $[N] |
| Monthly Revenue | $[N] |
| Net Burn | $[N] |
| **Runway** | **[N] months ([date])** |

## Scenario Comparison

| Scenario | Runway | Cash-Out Date | Key Assumption |
|----------|--------|---------------|----------------|
| 🟢 **Optimistic** | [N] mo | [date] | Revenue grows [X]% MoM |
| 🟡 **Base Case** | [N] mo | [date] | Current trajectory |
| 🔴 **Pessimistic** | [N] mo | [date] | Revenue drops [X]%, burn +[Y]% |
| 💀 **Zero Revenue** | [N] mo | [date] | All revenue stops |

## Monthly Projection

| Month | Revenue | Burn | Net Burn | Cash Balance |
|-------|---------|------|----------|--------------|
| [M1] | $[N] | $[N] | $[N] | $[N] |
| [M2] | $[N] | $[N] | $[N] | $[N] |
| ... | ... | ... | ... | ... |
| [MN] | $[N] | $[N] | $[N] | $0 ← ⚠️ |

## Decision Framework

### If Runway < 6 months:
🔴 **URGENT** — Start fundraising NOW or cut costs
- Fundraising typically takes 3-6 months
- Options: raise, cut burn, accelerate revenue

### If Runway 6-12 months:
🟡 **PLAN** — Begin fundraising prep
- Build investor pipeline
- Hit key milestones for better valuation
- Consider bridge round if needed

### If Runway > 12 months:
🟢 **COMFORTABLE** — Focus on growth
- Invest in growth initiatives
- Don't get complacent (burn discipline)

## Cost Reduction Levers
| Action | Monthly Savings | Impact |
|--------|----------------|--------|
| [e.g., Defer hire #3] | $[N] | +[N] months runway |
| [e.g., Switch to cheaper cloud] | $[N] | +[N] months runway |
| [e.g., Reduce marketing spend] | $[N] | +[N] months runway |
