What is a Vote Percentage?
Vote percentage (also known as vote share) is a metric that reveals what portion of the total electorate voted for a specific candidate, resolution, or option. It is universally used in political elections, corporate shareholder meetings, union strikes, and online polls to determine clear winners.
By converting raw vote counts into percentages, election officials and the public can easily understand the margin of victory, regardless of whether 100 people voted in a local club election or 150 million people voted in a national presidential race. If you only need to quickly find the share of a single candidate against a known total ballot count, you can also use our Percentage of Total Calculator.
How to Calculate Vote Percentage for Multiple Candidates
Formula: (Candidate Votes ÷ Total Votes) × 100
When dealing with multiple candidates, calculating the percentage requires you to first establish the "Denominator" (the total number of valid votes). Our calculator auto-sums the candidate inputs to find this for you.
Step-by-Step Example:
Suppose Candidate A gets 400 votes, and Candidate B gets 600 votes.
1. Find Total: 400 + 600 = 1,000 Total Votes.
2. Candidate A Share: 400 ÷ 1,000 = 0.40. Multiply by 100 = 40%.
3. Candidate B Share: 600 ÷ 1,000 = 0.60. Multiply by 100 = 60%.

How to Calculate Voter Turnout
While vote share compares candidates against each other, voter turnout compares the number of actual voters against the total population of eligible (or registered) voters.
Turnout Formula: (Total Votes Cast ÷ Registered Voters) × 100
You can use this calculator for turnout! Just enter the Total Votes Cast in the Candidate 1 row, and the Registered Voters in the "Total Votes (Optional)" box.
Frequently Asked Questions
1. What happens to invalid or blank votes?
In most official elections, the denominator only includes valid votes. Spoiled or blank ballots are excluded when calculating a candidate's share. However, if you want to include them, enter the total including blanks into our "Total Votes (Optional)" field, and it will calculate an "Other / Unassigned" percentage.
2. Can a candidate win with less than 50%?
In a "first-past-the-post" or plurality voting system with three or more candidates, the winner only needs to have the highest percentage of votes, which could theoretically be 34% or 40%.
3. How do I calculate vote percentage in Excel?
If cell A1 holds Candidate A's votes, and cell B1 holds the Total Votes, type the formula =A1/B1 into a new cell. Then, format that new cell as a Percentage using the toolbar.
4. What does "margin of victory" mean?
The margin of victory is the difference in percentage points between the first-place winner and the second-place runner-up. If Candidate A gets 55% and Candidate B gets 45%, the margin of victory is 10 percentage points.
