🏎️ Motorsport Lap Time & Stint Calculator

🏎️ Motorsport Lap Time & Stint Calculator

Turn a lap time into an average speed and a full race duration, see how much each pit stop costs, and — if you have a rival's lap time — watch the gap grow lap by lap.

Optional — leave blank to skip the gap analysis.
Assumptions

Average speed is lap length ÷ lap time. Race time is laps × lap time plus the pit-stop losses, assuming every lap is run at the same pace. In reality tyres degrade and fuel burns off, so treat this as the clean-air, no-traffic baseline rather than a race simulation.
