Pit Stop Delta Calculator

Summary

Enter in-lap, stationary, and out-lap times plus your green-flag lap time to see the exact time delta a pit stop costs or saves.

How it works

1. Enter your green-flag (normal race pace) lap time.
2. Enter the in-lap time, the lap where the driver enters the pits.
3. Enter the stationary time spent in the pit box (tire change, refuel, etc.).
4. Enter the out-lap time, the lap where the driver exits the pits and returns to pace.
5. The calculator shows the total pit stop time and the net delta versus running three green-flag laps.

Use cases

• Compare pit crew performance between different stops.
• Decide whether a splash-and-dash is worth the time loss late in a race.
• Estimate the undercut or overcut gap needed to jump a rival on strategy.
• Analyze sim racing or esports pit stop data for setup improvements.
• Teach kart racing or club racing strategy basics.
• Benchmark real-world pit crew times against professional series averages.
