Pit Stop Time Calculator

It is the extra time a stop costs versus driving that same stretch at racing speed, covering the pit lane speed limit, entry and exit. It is also called the pit lane delta, and it is separate from how long the car sits still.

Time lost per stop equals the pit lane time loss plus the stationary service time. The total lost multiplies that per-stop figure by the number of stops. For example 22 plus 3.5 is 25.5 seconds per stop.

As minutes:seconds.milliseconds. So 51 seconds shows as 0:51.000 and 66.6 seconds shows as 1:06.600. The raw total in seconds is shown underneath for quick copying into a spreadsheet.

Yes. The pit lane loss is the time to travel through the restricted pit lane, while the service time is how long the car is stationary for tyres and fuel. Adding both gives the true cost of one full stop.

It varies a lot. A modern Formula 1 tyre-only stop can be around 2 to 3 seconds stationary, while an endurance stop that also refuels and changes drivers can run much longer. Enter the figure that matches your series.

Yes. The field only accepts a whole number of 1 or more, since you cannot make a fraction of a stop. The two input times can be decimals, such as 3.5 or 19.8 seconds.

Compare a lap with a stop to a clean lap, or use a published figure for the circuit. It typically ranges from about 15 to 30 seconds depending on pit lane length and the speed limit.

Knowing the total time lost lets you weigh a one stop against a two stop plan by comparing it with the lap time you gain on fresh tyres or with a lighter fuel load. If the tyre gain beats the extra stop's cost, the extra stop pays off.

No. It is a plain calculation that runs in your browser, so the times and stop count you enter never leave your device and nothing is sent to a server.
