How it works
- The D'Hondt method allocates seats by dividing each party's votes by 1, 2, 3… and awarding the available seats one at a time to the largest resulting quotients.
- Enter one party and its votes per line, set the total number of seats to allocate, and the tool calculates how many seats each party wins.
- To show the process, the tool lists each party's votes ÷1, ÷2, ÷3… and marks the top quotients, one per seat, that win a seat.
- When quotients tie for the last seat, it is generally decided in favor of the party with more votes or by lot; this tool gives priority to the party with more votes.
- The D'Hondt method is used for proportional representation in many national and regional elections.
- Votes may be entered as integers or decimals greater than zero. The method produces few wasted votes and tends to slightly favor larger parties.
