What Is "Expected Vote" in Elections? A Simple Guide
Have you ever watched election night coverage and seen a number called "Expected Vote"? It sounds official, but what does it actually mean? Don’t worry—we’re going to break it down like you’re five years old.
What Does "Expected Vote" Mean?
Think of Expected Vote as a best guess.
It’s the total number of votes experts think will be counted in a race once every single ballot is tallied.
Important: It’s not the final number. It’s an estimate—like guessing how many jellybeans are in a jar before you count them.
How Is It Calculated? (Step by Step)
Experts don’t just make it up. They use real data to build their estimate:
- Early Voting Numbers – How many people already voted by mail or in person before Election Day.
- Election Day Reports – Updates from county election officials on how many people are showing up at polling places.
- Historical Trends – Past turnout in similar elections helps fine-tune the guess.
- Registration Data – How many people are registered to vote in that area.
All of this gets fed into a model that spits out the Expected Vote.
Why Does the Number Change?
You might see the Expected Vote go up or down throughout election night. That’s totally normal! Here’s why:
- New precincts report – More data = better estimate.
- Turnout surprises – More (or fewer) people show up than expected.
- Late-arriving ballots – Some mail ballots arrive after Election Day (depending on state rules).
Key Point: The Expected Vote updates in real time as NBC News gets fresh info from the Associated Press and local election offices.
Where Does This Info Come From?
- Vote Data: Collected by the Associated Press (AP) — a nonpartisan news organization that gathers results from every county.
- Projections: Made by the NBC News Decision Desk — a team of analysts who use the AP’s data to make calls on winners.
Why Should You Care?
- It helps you understand how much of the vote is in vs. how much is left.
- It gives context to candidate percentages (e.g., "Candidate A has 52% with 70% of expected vote counted").
- It prevents jumping to conclusions too early.

FAQ
Q: Is Expected Vote the same as "votes counted so far"?
A: Nope! "Votes counted" is actual. "Expected Vote" is the projected total.
Q: Who decides the Expected Vote?
A: The NBC News Decision Desk, using data from the Associated Press.
Q: Can the Expected Vote be wrong?
A: Yes—it’s an estimate. But it gets more accurate as more precincts report.
Q: Why does it matter if a race has "80% of expected vote in"?
A: It tells you how complete the picture is. At 80%, the leader is likely to win—but not guaranteed.
Q: Does every state report the same way?
A: No. Some count fast; others take days (especially with mail ballots). That’s why Expected Vote adjusts.
