Election night coverage is one long exercise in dividing votes by totals — and getting the denominator right is where amateurs stumble. A candidate's vote percentage is their votes divided by all valid votes cast, times 100. In a school board race with 4,200 total votes, a candidate with 1,890 has exactly 45%. Simple — until you decide whether blank ballots, spoiled ballots, and write-ins belong in the total, because each choice moves every percentage.

Thresholds give percentages their drama. Many US local measures need a simple majority (50% + 1 vote); some bond issues require a supermajority of 55% or two-thirds. A proposition at 54.7% fails under a 55% rule while passing under a majority rule — same votes, opposite outcomes, which is why the percentage matters more than the raw count.

This calculator handles up to four candidates or options. Enter each contender's votes in the Candidate 1 Votes through Candidate 4 Votes boxes, and it returns every share of the total — the numbers behind the winner's speech and the loser's concession.

With the pre-filled defaults — Candidate 1 Votes 5,400, Candidate 2 Votes 3,200, Candidate 3 Votes 800, Candidate 4 Votes 600 — the Vote Percentage Calculator returns Total Votes 10,000, Candidate 1 (%) 54.00, Candidate 2 (%) 32.00, Candidate 3 (%) 8.00, Win Margin (%) 22.00. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
