What is a Quorum?
A quorum is the minimum number of members required to be present at a meeting before official business can be conducted. Without a quorum, any votes or decisions made may be considered invalid.
The concept of quorum is essential in corporate governance, legislative bodies, non-profit organizations, homeowners associations, and any group that makes collective decisions through voting.
How to Calculate Quorum
The formula for calculating quorum depends on your organization's bylaws:
For a simple majority, divide the total number by 2 and add 1. For example, if you have 25 members, the quorum would be 13 (25 ÷ 2 = 12.5, rounded down to 12, plus 1 = 13).
Common Quorum Types

Most common requirement for regular meetings
