An interactive, single-file FinOps and cloud economics calculator for modeling break-even, pricing floor, cloud efficiency, and optimization actions.

This project is built as a landing-page style tool that guides users through:

1. What the tool does and who it is for
2. Author credibility and context
3. A direct call-to-action into the calculator
4. Live calculator inputs/outputs and chart analysis

• How many clients are needed to break even?
• What is the minimum viable price per client at current scale?
• Is cloud spend efficient relative to revenue (CCER)?
• How much can committed use discounts improve cloud economics?
• Which FinOps actions should be prioritized for the current health zone?

• Single-file implementation (index.html) with inline CSS and JavaScript
• D3.js interactive chart (show/hide curve controls, hover readouts, zones)
• Real-time recalculation as users type
• Structured calculator groups:
  • Group A: Business snapshot inputs
  • Group B: Model tuning inputs
  • Group C: Auto-calculated KPIs
  • Group D: Cloud provider selection (with provider badges)
  • Group E: Health zone scoring and recommendation engine
• Formula cards with explanatory tooltips
• Academic and practitioner references section
• Landing-page navigation links to jump to Calculator, Chart, and Formulas
• Mobile-friendly responsive behavior

The calculator uses a practical cloud economics model based on:

• Development cost decay with scale
• Super-linear infrastructure growth
• Committed use discount effect
• Break-even thresholding
• Contribution margin and CCER health scoring
• Minimum price floor based on target margin

Representative equations include:

• DC(n) = K * n^-a
• IC(n) = c * n^b
• IC_cud(n) = g * c * n^(b*0.96)
• MP(n) = TC(n) * (1 + m)

• index.html - complete application (UI, styles, model logic, chart rendering)
• perfect-finops-calculator-prompt.md - implementation requirements and specification

No build step is required.

Open index.html in your browser.

python3 -m http.server 8080

Then open http://localhost:8080.

Because this is a static single-page file, deployment is straightforward:

• GitHub Pages
• Netlify
• Vercel static hosting
• Any static web server

1. Read the landing intro and click Get Started
2. Fill Group A with known business metrics
3. Optionally tune Group B assumptions
4. Review Group C KPI outputs
5. Select cloud providers in Group D
6. Use Group E health score and recommendations
7. Explore the chart section for curve behavior and zone transitions
8. Review formulas for model interpretation

• This calculator is intended for decision support and scenario modeling.
• Inputs and outputs should be validated against your actual billing, unit economics, and pricing data before operational decisions.
