Guide to Mandator — what can you do?▼

Mandator gives you the tools to understand how votes become seats — and what would happen if things were different. Build scenarios, explore outcomes, and learn how the system works.

🗳️Candidate lists for 25 October 2026 — the 12 proclaimed lists are pre-loaded in ballot order. Enter the number of votes (or a percentage) to see the seat allocation. The ballot is not final: lists can be submitted until 4 October, so the number may still change.
📊Enter percentages or number of votes — you can adjust each list using a slider, percentage or exact number of votes. The total is tracked automatically.
↕Normalize to 100% — if the sum of percentages is off, one click fixes everything proportionally.
↻Change the status of each list — mark who is the ruling majority, who is opposition, who abstains. The parliamentary display updates immediately.
🟢Visual display of seats — lists that passed the threshold get a green badge with the number of seats; lists below the threshold are greyed out.
📅Load historical elections — accurate results from 2008 to 2023. The threshold and coefficient for national minority lists automatically adjust to the year (5% until 2016, 3% from 2020).
🗳️Government formation vote — each historical preset shows how many MPs voted for the government.
📈Historical data — a tabular overview of registered voters, turnout, valid ballots, invalid ballots and votes that entered/did not enter seat allocation, for each election from 2008 to 2023.

Parliamentary Seat Distribution
Ruling majority Abstaining Opposition N/A

The total votes for each list are divided by 1, 2, 3… up to 250. Quotients are sorted from largest to smallest — the top 250 win seats. Green = seat won.

The threshold is 3% of all ballots cast - total votes in the boxes, including invalid ones (from 2020; previously 5%). National minority lists receive a 35% increase in their coefficients (from 2020; previously no increase).

📊D'Hondt favours larger parties▼

The highest quotient system sounds neutral, but in practice it slightly favours larger lists. Result: a political actor with 40% of votes often wins more than 40% of seats, while an actor with 5% wins slightly less than 5%.

Concrete example — 2023 parliamentary elections: the list "Serbia Must Not Stop" won 46.75% of votes, but received 129 out of 250 seats, which is 51.6%. The "Serbia Against Violence" list with 23.66% of votes received 58 seats (23.2%) - nearly proportional, as they are also a large list. Smaller lists typically receive a slightly smaller share of seats than their share of votes.

⚖️Threshold: 3% or you're out▼

Each list must win at least 3% of the total number of ballots cast (all voters who turned out) to participate in seat allocation. The exception is national minority parties — they participate regardless of percentage.

Important: the 3% threshold has been in effect since the 2020 parliamentary elections. In all previous elections (2008, 2012, 2014, 2016) the threshold was 5%. The 35% increase in D'Hondt coefficients for national minority lists also applies from 2020 — in earlier elections, minority parties did not have this increase.

🏛️National minority lists — natural threshold instead of electoral threshold▼

The electoral threshold for entering parliament is 3%, but national minority parties are an exception — for them, a natural threshold applies. This means there is no minimum percentage, but to win a seat, a list must win enough votes to 'beat' at least one step in the D'Hondt allocation. The D'Hondt formula divides the votes of lists that passed the threshold (and minority lists) by 1, 2, 3… and sorts all quotients — the 250th largest quotient determines the minimum votes needed for one seat. In the interest of fairness, from 2020 minority lists receive a 35% increase in their coefficients.

🗑️Votes below the threshold simply disappear▼

If a list does not pass the threshold (3% of total ballots cast), all votes that list received are excluded from seat allocation — as if those voters never voted. These votes do not just disappear for that list — they effectively increase the percentage won by parties that did pass the threshold.

A dramatic difference in practice: in the 2016 only 3.6% of valid ballots remained below the threshold (around 130,000). In the 2014, due to the then-applicable 5% threshold, as many as 20.1% of valid ballots — nearly 700,000 voters whose votes did not enter seat allocation. Dveri (3.69%), DSS (4.38%), LDP (3.48%) and United Regions of Serbia (3.14%) all passed 3% but not 5%, and received zero seats.

📋The threshold is based on all ballots cast▼

The threshold is calculated from the total number of ballots cast - every voter who turned out, including invalid ballots. Invalid votes (blank or incorrectly filled) belong to no list, but they still count towards the threshold base. In the 2023 elections 3,820,746 voters turned out (about 104,000 invalid ballots), so the threshold was 3% of 3,820,746 - about 114,600 votes.

🗳️You voted for a list, not a person▼

In Serbia, voters vote for an electoral list, not for individual candidates. Which candidates from a list win seats depends exclusively on their order on the list, determined by the party itself — there is no preferential voting. A voter cannot influence who specifically becomes an MP, only how many seats the list receives.

🏛️Seats are just the beginning — who actually governs?▼

Forming a government requires an absolute majority — 126 out of 250 MPs. But the number that votes for the government does not have to equal the number of seats won by the ruling parties in the election.

The reason: parliamentary seats in Serbia are free mandates, meaning an MP or even an entire parliamentary group can vote against the party line, support a government that their party nominally opposed, or leave their group and join another. In practice, it has happened that parties that were in opposition after the election supported the government during the vote, or that MPs crossed over to the ruling side during the term.

That is why Mandator displays the official data on how many MPs voted for the formation of each government — that number often differs from the total seats of the ruling coalition from the election. And that is why in Mandator you can change the status of any parliamentary group from ruling majority to opposition and vice versa — and judging by experience, it is more often the latter.
