The NFL Overtime Calculator helps you calculate overtime clock information for NFL regular-season and postseason games. Select the game type, enter the overtime period, and enter the time remaining on the overtime clock.
The calculator shows the time elapsed, time remaining, overtime period length, total overtime elapsed, and important information about the selected overtime format.
NFL Overtime Calculator
Select the game type and enter the current overtime period and time remaining on the NFL overtime clock.
Enter the time currently remaining on the overtime clock. Regular-season overtime has a maximum one 10-minute period, while postseason overtime uses 15-minute periods and can continue when required to determine a winner.
This calculator calculates overtime clock information only. NFL overtime outcomes also depend on possession, scoring, and other applicable NFL overtime rules. This calculator does not determine possession opportunities, scoring outcomes, or official game results.
How Does NFL Overtime Work?
NFL overtime begins when the score is tied at the end of regulation.
The overtime format differs between regular-season games and postseason games.
- Regular-season overtime has a maximum of one 10-minute period.
- Postseason overtime uses 15-minute periods.
- Regular-season games can end in a tie.
- Postseason games continue until a winner is determined.
Current NFL overtime rules generally provide both teams with an opportunity to possess the ball, subject to specific rule exceptions. The game clock and possession rules both affect how an overtime game can end.
This calculator focuses on overtime clock calculations. It does not determine possession rights, scoring outcomes, or official overtime rulings.
NFL Regular Season Overtime Rules
NFL regular-season overtime has a maximum of one 10-minute overtime period.
Under the current overtime format, both teams generally have an opportunity to possess the ball during overtime, subject to specific exceptions.
However, there is an important time limitation.
The regular-season overtime period does not extend beyond 10 minutes, even if the second team's opportunity to possess the ball has not ended.
If the score is tied when the 10-minute overtime period expires, the game ends in a tie.
The calculator uses the following period length:
Regular Season Overtime Period = 10 Minutes
NFL Postseason Overtime Rules
NFL postseason overtime uses 15-minute overtime periods.
Postseason games cannot end in a tie. Additional overtime periods can continue when necessary to determine a winner.
Under the overtime rules, another postseason overtime period begins if:
- The score is tied at the end of a 15-minute overtime period, or
- The second team's initial possession has not ended when the overtime period expires.
The calculator uses the following period length:
Postseason Overtime Period = 15 Minutes
NFL Overtime Possession Rules
Overtime in the NFL is not determined only by the clock. Possession and scoring situations are also important.
Under the current overtime format, both teams generally have an opportunity to possess the ball during overtime, subject to specific exceptions.
After both teams have had an opportunity to possess the ball, the overtime game can enter a next-score-wins situation depending on the scoring and possession circumstances.
There are also specific exceptions involving situations such as a safety by the team that kicked off to begin overtime.
Because overtime outcomes depend on detailed possession and scoring rules, this calculator does not attempt to determine:
- Which team receives the ball.
- Whether both teams have completed a possession.
- Whether a scoring play ends the game.
- Which team wins overtime.
Instead, the calculator provides overtime clock information based on the selected game type and overtime period.
NFL Overtime Time Remaining Formula
The calculator uses the time remaining shown on the overtime game clock.
The formula for time elapsed is:
Time Elapsed = Overtime Period Length − Time Remaining
For example, in a regular-season overtime period:
10:00 − 7:30 = 2:30 elapsed
The calculator then displays both the remaining and elapsed overtime time.
How to Use the NFL Overtime Calculator
Follow these steps:
- Select Regular Season or Postseason.
- Enter the current overtime period.
- Enter the minutes remaining on the overtime clock.
- Enter the seconds remaining on the overtime clock.
- Click Calculate Overtime Time.
The calculator will show the overtime clock information for the selected game situation.
NFL Overtime Calculator Example
Suppose an NFL regular-season game is in overtime and the clock shows:
- Game Type: Regular Season
- Overtime Period: 1
- Time Remaining: 7:30
A regular-season overtime period has a maximum length of 10 minutes.
The elapsed time calculation is:
10:00 − 7:30 = 2:30 elapsed
The calculator will show:
- Time Remaining: 7:30
- Time Elapsed: 2:30
- Period Length: 10:00
Postseason Overtime Example
Suppose an NFL postseason game is in its first overtime period and the clock shows 6 minutes and 15 seconds remaining.
- Game Type: Postseason
- Overtime Period: 1
- Time Remaining: 6:15
A postseason overtime period lasts 15 minutes.
The elapsed time calculation is:
15:00 − 6:15 = 8:45 elapsed
The calculator will show:
6:15 remaining and 8:45 elapsed.
What Is Total Overtime Time Elapsed?
Total overtime elapsed represents the amount of overtime game-clock time that has passed since the beginning of the first overtime period.
During the first overtime period, total overtime elapsed is the same as the elapsed time in the current period.
For example:
Overtime Period 1
Time remaining: 10:00 in a 15-minute postseason period.
Time elapsed:
15:00 − 10:00 = 5:00
Total overtime elapsed is also:
5:00
Multiple Postseason Overtime Periods
Postseason games can continue into additional overtime periods when required to determine a winner.
For example, suppose a postseason game is in overtime period 2 and the clock shows:
10:30 remaining
The current overtime period is 15 minutes long.
The current period elapsed time is:
15:00 − 10:30 = 4:30
Because the game has reached overtime period 2, the first overtime period reached its period boundary.
The total overtime elapsed is:
15:00 + 4:30 = 19:30
The calculator uses completed overtime periods plus the elapsed time in the current overtime period when displaying total overtime elapsed.
Regular Season vs Postseason NFL Overtime
| Feature | Regular Season | Postseason |
|---|---|---|
| Overtime Period Length | 10 minutes | 15 minutes |
| Maximum Overtime Periods | One period | Additional periods can continue |
| Can the Game End in a Tie? | Yes | No |
| Clock Limitation | Maximum 10 minutes | Additional periods when required |
| Possession Opportunity | Both teams generally have an opportunity, subject to rules and the 10-minute maximum | Both teams generally have an opportunity, subject to specific exceptions |
Can an NFL Regular Season Game End in a Tie?
Yes. An NFL regular-season game can end in a tie.
Regular-season overtime has a maximum of one 10-minute period.
Even if a team's possession opportunity has not ended, the overtime period does not extend beyond the 10-minute maximum.
If the score remains tied when overtime time expires, the game ends in a tie.
Can an NFL Playoff Game End in a Tie?
No. NFL postseason games must determine a winner.
If the score is tied at the end of a postseason overtime period, or if the second team's initial possession has not ended, another overtime period begins according to the applicable NFL rules.
Additional overtime periods can continue until the game is decided.
Does Each Team Get the Ball in NFL Overtime?
Under the current NFL overtime format, both teams generally have an opportunity to possess the ball during overtime.
However, the rules include specific exceptions and detailed possession situations.
There is also an important difference between the regular season and postseason.
In the regular season, there is a maximum one 10-minute overtime period. The clock does not automatically extend to guarantee that an unfinished possession will continue after time expires.
In the postseason, additional overtime periods can continue when necessary under the overtime rules until a winner is determined.
What Happens When Overtime Time Reaches Zero?
Regular Season
If the 10-minute overtime period reaches zero and the score is tied, the game ends in a tie.
The overtime period does not continue into another period during the regular season.
Postseason
If a postseason overtime period reaches zero, another overtime period can begin if the game remains tied or if the second team's initial possession has not ended.
Postseason overtime continues as necessary until a winner is determined.
Why Does the Calculator Ask for the Overtime Period?
The overtime period is important for postseason games because multiple overtime periods can occur.
For example:
- Overtime Period 1
- Overtime Period 2
- Overtime Period 3
Each postseason overtime period is 15 minutes long.
Regular-season games have only one overtime period, so the calculator automatically uses overtime period 1 when Regular Season is selected.
Why Does the Calculator Use Time Remaining?
NFL game broadcasts normally show the amount of time remaining on the game clock.
For example:
- 10:00 means 10 minutes remaining.
- 7:30 means 7 minutes and 30 seconds remaining.
- 0:45 means 45 seconds remaining.
Using time remaining makes the calculator easier to use during a live game because users can enter the time directly from the overtime game clock.
Does the NFL Overtime Calculator Determine the Winner?
No.
This calculator calculates overtime timing information only.
It does not determine:
- The winning team.
- Possession rights.
- Whether a team has completed its possession opportunity.
- Whether a touchdown, field goal, turnover, safety, or other play ends the game.
- Official NFL overtime rulings.
Actual NFL overtime outcomes depend on the game situation and the applicable NFL overtime rules.
Can I Use the Calculator During a Live NFL Game?
Yes.
You can enter the current overtime period and the exact time shown on the overtime game clock.
For example, if a regular-season overtime clock shows:
6:42 remaining
Enter:
- Minutes Remaining: 6
- Seconds Remaining: 42
The calculator will show:
Time Elapsed: 3:18
because:
10:00 − 6:42 = 3:18
How Is Total Overtime Elapsed Calculated?
The calculation depends on the selected game type and overtime period.
Regular Season
Regular-season games have only one overtime period.
Total Overtime Elapsed = Current Period Elapsed
Postseason
For later overtime periods, the calculator adds the full length of completed overtime periods to the elapsed time in the current period.
The formula is:
Total OT Elapsed = Completed Overtime Periods × 15 Minutes + Current Period Elapsed
This calculation is designed for a game currently being played in the selected overtime period.
