Spry Plan is a free Chrome extension designed to function as a personal Meeting Cost Calculator, enabling users to understand the financial implications of scheduled meetings. By integrating with Google Calendar, it provides visualizations of meeting costs and participant wages, allowing for more informed scheduling decisions. The tool emphasizes privacy, ensuring that cost data is only visible to the user and not shared with other participants.

Key features include the ability to calculate the cost of each meeting, display the cost of time for each participant, and hide costs for screenshots and screen sharing. Users can customize individual rates based on yearly, monthly, or hourly wages, and all data is stored locally on the user's computer, maintaining confidentiality. This tool aims to enhance productivity and efficiency in meetings through constant insights and easy integration with existing calendar systems.
