Meeting Cost Calculator

Inspiration After reading studies showing that unnecessary meetings cost companies over $100 billion annually, I wanted to create a simple tool that makes the invisible visible. The problem isn't just that meetings are expensive—it's that nobody sees the cost in real-time. When people watch dollars accumulate like a taxi meter during a meeting, behavior changes instantly.

What it does Meeting Cost Calculator is a Chrome extension that brings financial transparency to meetings:

Quick Calculator: Input attendees, hourly rates, and duration to instantly see total meeting cost, per-minute breakdown, and annual impact for recurring meetings Live Timer: A real-time "taxi meter" that shows costs accumulating during actual meetings Smart Defaults: Remembers your settings for quick recalculations Data-Driven Decisions: Helps teams justify meeting policies with concrete numbers Real Impact For a 100-person company with $75K average salary:

Reducing just 2 hours of unnecessary meetings per week per person Saves $374,400 annually How I built it I focused on simplicity and speed:

Chrome Extension (Manifest V3) for easy access from any tab Vanilla JavaScript for core calculation logic—no frameworks needed HTML5/CSS3 for a clean, professional interface Chrome Storage API to persist user settings Fully client-side—no backend, no API calls, instant performance The entire project runs locally with zero dependencies, making it fast, secure, and privacy-friendly.

Challenges I ran into Balancing simplicity with functionality: I wanted powerful features without overwhelming users who need quick answers during meetings Real-time accuracy: Ensuring the live timer calculates costs precisely, even when paused and resumed Intuitive UX: Making the interface obvious enough that anyone can use it in seconds without instructions Visual design: Creating a professional look that conveys credibility for business use Accomplishments that I'm proud of ✅ Built a fully functional MVP with real business value ✅ Zero setup required—users can test it instantly by opening test.html in any browser ✅ Solves a real problem with measurable ROI ✅ Clean, professional UI that looks like enterprise software ✅ No external dependencies or complex installation What I learned Simple solutions can have massive impact: You don't need complex tech to solve expensive problems Visibility drives behavior: Making costs visible is often enough to change decision-making Chrome Extension best practices: Manifest V3 requirements, storage APIs, and popup UX patterns The power of focus: Doing one thing really well beats doing many things poorly What's next for Meeting Cost Calculator 📅 Google Calendar integration for automatic cost tracking across all meetings 📊 Team analytics dashboard showing meeting costs by department, person, or project 💬 Slack/Teams integration to send cost summaries after meetings 🌍 Multi-currency support for global teams 📈 Company-wide reporting with trends, insights, and recommendations 🤖 AI suggestions for optimal meeting duration and attendance based on historical data
