Intervention ROI Calculator

📈 Discover Which Longevity Habits Deliver the Most Years per Dollar (or Minute)

Is $100/month on NMN giving you more lifespan benefit than 3 weekly workouts?
Should you invest in a $3,000 red light panel—or just take more walks in daylight?

Welcome to the Intervention ROI Calculator, your personal cost-benefit engine for longevity. This tool helps you compare interventions—supplements, habits, devices, therapies—based on estimated biological impact, time investment, and financial cost.

Because longevity is not just about what works—it’s about what works best for you.

🧠 Why ROI for Longevity?

In health optimization, there are thousands of options, but your time, money, and energy are limited.

The ROI Calculator answers:

• What gives me the biggest biological bang for my buck?
• What’s the opportunity cost of time-intensive routines?
• How do different stacks compare per year-of-health gained (YHG)?
• Where can I reallocate effort for better results?

🛠️ How the Calculator Works

1. You input:
   • Intervention type (e.g., Rapamycin, Zone 2 training, sauna)
   • Cost/month (or one-time)
   • Time required/week
   • Current biological age
   • Lifestyle goals (e.g., longevity, metabolic health, cognitive performance)
2. We calculate:
   • Estimated biological impact score based on clinical evidence
   • Cost-efficiency metric: YHG (Years of Health Gained) per $1
   • Time-efficiency metric: YHG per hour
   • Recommended priority tier (Essential, High-ROI, Medium, Low-ROI)
3. You receive:
   • Visual chart comparing ROI across multiple interventions
   • Suggested alternatives with higher returns
   • Links to science sources and how-to guides
   • Option to add to your Protocol Builder plan

📊 Example Comparison Output

Note: YHG estimates are based on meta-analyses, human trials, and mechanistic plausibility. Assumptions are always transparent.

📦 Key Features

• Interactive sliders for time and money
• Scientific evidence score (1–5 stars with citations)
• Personalized biological context filtering
• Auto-sync with your Protocol Builder plan
• “What If?” simulator — test adding/removing interventions
• Exportable chart for visualizing your optimized stack

🔐 Built on Transparency & Evidence

• We list every source used to estimate YHG and impact scores
• All models include confidence intervals and assumptions
• We do not promote affiliate products by default in this tool
• You’re in control: your data stays local unless you save to account

🚀 Why Use the ROI Calculator

• To spend less but gain more
• To prioritize what actually moves the needle
• To track your budget as you add/replace interventions
• To make smarter longevity decisions year after year

This is the dashboard you wish came with every supplement bottle, every biohacking pitch, and every health app.
