Pit Stop Time Calculator
Enter the pit lane time loss and the stationary service time to see the time lost per stop, then multiply by the number of stops for the race total.
How to calculate pit stop time loss
- Enter the pit lane time loss per stop in seconds.
- Enter the stationary service time per stop in seconds.
- Set the number of stops to read the total time lost.
Examples
22 s pit lane, 3.5 s service, 2 stops
22 s + 3.5 s, 2 stops
25.5 s per stop, 0:51.000 total
Single stop
22 s + 3.5 s, 1 stop
0:25.500 total
Frequently asked questions
What is pit lane time loss?
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.
How is the time lost per stop calculated?
Time lost per stop equals the pit lane time loss plus the stationary service time. Total time lost multiplies that by the number of stops in the race.
Should I include the service time separately?
Yes. The pit lane loss is the time to travel through the pit lane, while the service time is how long the car sits still for tyres and fuel. Add both for a full stop.
How do I find the pit lane time loss for a track?
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 speed limit.
How does this help with strategy?
Knowing the total time lost lets you compare a one stop versus two stop plan against the lap time you gain on fresh tyres or with less fuel on board.
