How Israeli Election Votes Translate to Knesset Seats Explained
Translated & summarized from i24NEWS Arabic by baba
After Israeli elections, votes are converted into 120 Knesset seats using a system that includes an electoral threshold and surplus vote calculations. Parties must secure at least 3.25% of valid votes to qualify for seat allocation. Remaining seats are distributed via the Bader-Ofer method, with surplus vote agreements between parties potentially influencing the final outcome.

- Parties must cross a 3.25% electoral threshold to be eligible for seat allocation.
- A "general measure" calculates a baseline number of votes per seat based on valid votes.
- The Bader-Ofer method distributes remaining seats based on parties' surplus votes.
- Surplus vote agreements allow parties to combine votes for additional seat allocation.
Following the conclusion of Israeli elections, the process of converting votes into the 120 Knesset seats begins. This complex system determines how many votes a party needs for a seat and what happens to surplus votes. A parliamentary seat, or "mandate" in Hebrew, represents one position in the Knesset. Seats are allocated to party lists based on their share of the vote, following specific legal mechanisms.
The calculation starts by dividing the total valid votes cast for parties that surpassed the electoral threshold by 120, yielding a "general measure" or baseline number of votes per seat. For instance, with 4.5 million valid votes from qualifying parties, the baseline is 37,500 votes per seat. However, this initial figure doesn't guarantee a party exactly one seat per 37,500 votes, as the final distribution depends on how remaining seats are allocated.
The exact number of votes required for a seat can fluctuate due to factors like voter turnout, the total number of valid votes, and the number of parties crossing the 3.25% electoral threshold. Only parties achieving this threshold are eligible for seat allocation; votes for parties below it are discarded. The fewer parties that cross the threshold, the lower the overall vote count used for seat distribution among the qualifying parties.
Surplus votes are not lost. If a party receives more votes than the baseline for its seats, the excess can be used in subsequent distribution phases. After the initial allocation, any remaining seats are distributed using the Bader-Ofer method, which considers the surplus votes each party holds relative to the seats they've already secured.
"Surplus vote agreements" allow two parties to pool their remaining votes before the election to compete for undistributed seats. This can grant a party an additional seat even if its individual surplus isn't the largest, significantly impacting the final seat count, especially in close elections. The Knesset consistently has 120 seats, but the vote value of each seat changes with the total valid votes cast by qualifying parties.
