To change the outcome: 651 voters would need to switch from Candidate A to Candidate B. This represents 6.64% of total votes cast.
In a plurality system, the candidate with the most votes wins, even without a majority. This is the most common system for single-winner elections in many countries.
Vote percentage = (Candidate Votes / Total Votes) x 100. A majority requires >50% of votes. A plurality means the most votes but not necessarily a majority. Margin of victory = Winner's votes - Runner-up's votes (or as percentage). Voter turnout = (Votes Cast / Registered Voters) x 100.
A vote percentage calculator determines each candidate's share of total votes cast in an election, helping analyze outcomes, determine winners, and understand voting patterns.
Vote Percentage
% = (Candidate Votes / Total) x 100
Voter Turnout
% = (Votes Cast / Registered) x 100
Majority Threshold
= (Total Votes / 2) + 1
Swing Votes
= (Winner - Runner-up) / 2 + 1
A majority means receiving more than 50% of all votes cast. A plurality means receiving the most votes among all candidates, which could be less than 50% when there are more than two candidates. For example, winning with 35% when opponents get 33% and 32% is a plurality, not a majority.
Vote percentage = (Candidate's Votes / Total Votes Cast) x 100. For example, if a candidate receives 5,000 votes out of 12,000 total, their percentage is (5000/12000) x 100 = 41.67%.
Margin of victory is the difference between the winner's votes and the runner-up's votes. It can be expressed as raw votes or as a percentage of total votes. A larger margin indicates a more decisive victory.
Voter turnout = (Total Votes Cast / Total Registered Voters) x 100. This metric shows civic engagement. High turnout (>60%) indicates strong voter participation; low turnout (<40%) may indicate voter apathy or barriers.
A supermajority is a voting threshold higher than a simple majority (>50%). Common supermajority requirements include 60% (three-fifths), 66.67% (two-thirds), or 75% (three-quarters). Supermajorities are often required for constitutional amendments or special decisions.
Swing is the number of votes that would need to change from the winner to another candidate to alter the outcome. Formula: Swing = (Winner Votes - Runner-up Votes) / 2 + 1. This represents the minimum vote shift needed.
Depending on the election system: (1) Plurality wins - highest vote-getter wins regardless of majority. (2) Runoff - top two candidates face a second election. (3) Instant runoff - ranked-choice votes are redistributed until someone has majority.
