NHL Goals After the First Period: Over 5.5 Odds From 0 to 4+ Goals
Across 17,921 NHL regular-season games, the first period barely changes how many goals are still to come. It changes the total through the goals already on the board.

- How does the number of goals scored in the first period change the chance that an NHL game goes over 5.5 or 6.5?
- Sample
- NHL regular season, 2010-11 to 2025-26 (2014-15 not included), 17,921 games
- 20.9%Over 5.5 after a scoreless first period
- 58.1%Over 5.5 after a two-goal first period
- 95.9%Over 5.5 after 4+ first-period goals
- 4.22Goals still to come after a 1-goal first
The first intermission is where I reset my view of a totals market. Two teams have shown me their legs, their goaltenders and their special teams for 20 minutes, and the scoreboard says 0, 1, 2 or more. The question here is simple: how far does that first-period count move the chance of the game going over 5.5 or 6.5 goals?
The headline answer: after a scoreless first, only 20.9% of games went over 5.5. After a two-goal first that rose to 58.1%, and after four or more it reached 95.9%. This is the base layer beneath my ice hockey over/under predictions work. The surprise sits underneath those figures, because the goals still to come hardly change at all.
Break 1Each first-period goal lifts the over by a large step
This chart sets both lines side by side for every first-period count. Across all games, 51.0% went over 5.5 and 40.1% went over 6.5. Splitting by the first period turns that near coin flip into a staircase: 20.9% after a 0-0 first, 37.2% after one goal, 58.1% after two, 78.2% after three.
The over 6.5 line follows the same climb from a lower base, from 13.5% after a scoreless first to 88.0% after four or more. The 95% ranges are tight, around ±1.4 points for the scoreless group, so the steps reflect sample size doing its job rather than noise.
All games: over 5.5 51.0%, over 6.5 40.1%. ci = 95% range of the over 5.5 rate.
View the data: over 5.5 and over 6.5 by first-period goals
| Over 6.5 | Over 5.5 | 95% range | |
|---|---|---|---|
| 0 goals (3,311 games) | 13.5% | 20.9% | ±1.4 |
| 1 goal (5,600 games) | 26.1% | 37.2% | ±1.3 |
| 2 goals (4,817 games) | 44.7% | 58.1% | ±1.4 |
| 3 goals (2,619 games) | 66.2% | 78.2% | ±1.6 |
| 4+ goals (1,574 games) | 88.0% | 95.9% | ±1 |
What I take from it is that each extra goal moves the over 5.5 rate by roughly 15 to 20 points. Few in-game variables move a totals line as hard as that.
Break 2Goals still to come stay flat whatever happened
This is the table I keep returning to. The average goals still to come after the first period is 4.24 after a scoreless first, 4.22 after one goal, 4.21 after two and 4.21 after four or more. A goal-laden opening period does not tell you the rest of the night will be wilder, and a quiet one does not tell you it will stay quiet.
The fair odds column turns that into prices. Over 5.5 after a scoreless first works out at 4.78, after one goal at 2.69 (with the under at 1.59), and after two goals at 1.72. By the time four or more are on the board, the fair over is 1.04 and the fair under 24.39.
| After 1st | Games | Share | Goals still to come | Over 5.5 | Fair over | Fair under |
|---|---|---|---|---|---|---|
| 0 goals | 3,311 | 18.5% | 4.24 | 20.9% | 4.78 | 1.26 |
| 1 goal | 5,600 | 31.2% | 4.22 | 37.2% | 2.69 | 1.59 |
| 2 goals | 4,817 | 26.9% | 4.21 | 58.1% | 1.72 | 2.39 |
| 3 goals | 2,619 | 14.6% | 4.19 | 78.2% | 1.28 | 4.59 |
| 4+ goals | 1,574 | 8.8% | 4.21 | 95.9% | 1.04 | 24.39 |
The main caveat: bookmakers adjust live lines at the intermission, so these are base-rate prices, not a playable edge in themselves. Their use is as a reference point, so I can see when a live number has drifted away from what history supports.
Break 3A scoreless first leaves many games short of four
The heatmap shows where final totals actually land. After a 0-0 first, 41.5% of games finished on 0-3 goals, against 22.4% after a one-goal first. At the other end, 65.1% of games with four or more early goals ended on 8+.
The detail I like most is the odd-even pattern. After a one-goal first, exactly 5 was the most common final total at 28.9%, while exactly 4 came in only 11.6%. The scoreless row shows a similar shape, with 24.6% on exactly 5 against 12.9% on 4.
Final total includes overtime; a shootout win counts as one goal.

| 0-3 | 4 | 5 | 6 | 7 | 8+ | |
|---|---|---|---|---|---|---|
| 0 goals (3,311) | 41.5% | 12.9% | 24.6% | 7.4% | 8.8% | 4.8% |
| 1 goal (5,600) | 22.4% | 11.6% | 28.9% | 11.1% | 15.7% | 10.4% |
| 2 goals (4,817) | 7.8% | 7.8% | 26.3% | 13.4% | 23.6% | 21.1% |
| 3 goals (2,619) | 1.4% | 3.4% | 17.1% | 11.9% | 29.7% | 36.5% |
| 4+ goals (1,574) | 0.0% | 0.6% | 3.6% | 7.9% | 22.9% | 65.1% |
One-goal wins, empty-net goals and overtime winners push totals onto odd numbers. That matters most on lines sitting right on the 5.5 and 6.5 boundary.
Break 4League scoring has pushed every row upwards
The season view stops me treating these rates as constants. After a one-goal first, over 5.5 ranged from 30.6% to 48.7% by season, and it was 46.9% in 2025-26. After a two-goal first, the rate ran from 47.3% to 64.1%, climbing with league scoring in the later seasons.
The scoreless line moves too, peaking at 31.8% in 2023-24 before falling back to 22.1% the following season. Two seasons were shortened and 2014-15 is missing, so single-season wobbles deserve less weight than the broader drift.
2014-15 is missing from the goal-event data; 2012-13 and 2020-21 were shortened seasons.

| 2025-26 | 63.2% | 46.9% | 22.8% |
My practical reading is to anchor on the recent seasons, not the full-sample average, when I compare a live price against these figures.
At the break
- Count what's banked
The rest of the game averages around 4.21 to 4.24 goals whatever the first period produced. Add that to the goals already scored and ask where the total sits relative to the line.
- Respect the scoreless first
After a 0-0 first, only 20.9% of games went over 5.5 and 41.5% finished on 0-3 goals. Treat a fair over price of 4.78 as the benchmark before backing a late flurry.
- Weight recent seasons
Over 5.5 after a one-goal first was 46.9% in 2025-26, well above the full-sample 37.2%. Check which era a reference figure comes from before relying on it.
Questions bettors ask
What percentage of NHL games go over 5.5 after a 0-0 first period?
Across 3,311 regular-season games with a scoreless first period, 20.9% went over 5.5 goals. That implies fair over odds of 4.78 before any bookmaker margin.
Does a high-scoring first period mean more goals later in an NHL game?
Not on average. The goals still to come were 4.24 after a scoreless first and 4.21 after four or more first-period goals, so the over rate rises mainly because those early goals are already counted.
How often does an NHL game go over 6.5 after two goals in the first period?
Over 6.5 landed in 44.7% of games with a two-goal first period, giving fair odds of 2.24. Over 5.5 in the same games came in 58.1%.
