Pit Stop Time Loss Calculator
Pit Stop Time Loss Calculator
The number television shows you is the stationary time. The number that costs you places is the total time lost: the stationary time plus the difference between crossing the pit lane at the speed limit and covering the same stretch at racing speed. A 2.4-second stop can cost 14.4 seconds.
Total time lost in the pit lane
The delta, not the stoptwo stops, 2.4 s stationary each, a 400 m pit lane at the FIA’s 80 km/h limit against 240 km/h on the track, with no extra allowance
Formula
the same stretch at racing speed (s) = length × 3.6 ÷ racing speed
transit penalty = transit at the limit − the same stretch at racing speed
time lost at one stop = stationary time + extra allowance + transit penalty
total = number of stops × time lost at one stop
- why 3.6
- a speed in km/h divided by 3.6 is a speed in m/s, because there are 3,600 seconds in an hour and 1,000 metres in a kilometre. So length in metres × 3.6 ÷ speed in km/h is a time in seconds, with no unit mixing
- the penalty is a difference, not a transit
- the eighteen seconds a 400 m pit lane takes at 80 km/h is not all lost: the car would have taken six seconds to cover that ground anyway. Twelve seconds is the penalty. Treating the whole transit as lost overstates the cost by half as much again
- it is independent of the stop
- the transit penalty contains no stationary time at all, so it is identical for a 1.9-second stop and a 6-second one. That is why the stationary share falls as the stop gets quicker and why the number on television is the small part
- a racing speed below the limit is a contradiction
- if the speed entered for the track is at or below the pit lane limit then the pit lane is not slowing the car down at all, the penalty turns negative, and the arithmetic says a stop gains time. The check row appears when that happens; it is an input error and not a finding
- nothing here is advice
- this page says what a stop costs. It does not say when to stop, how many times to stop, how fast to drive or what strategy to run, and no governing body publishes any of those either
Worked example
two stops, 2.4 s stationary each, a 400 m pit lane at the FIA's 80 km/h limit against 240 km/h on the track, with no extra allowance
80 km/h is 22.222 m/s, so 400 m of pit lane at the limit takes 400 × 3.6 ÷ 80 = 18.000 seconds
240 km/h is 66.667 m/s, so the same 400 m on the track takes 400 × 3.6 ÷ 240 = 6.000 seconds
The transit penalty is 18.000 − 6.000 = 12.000 seconds, and it is the same whatever happens in the pit box
One stop therefore costs 2.4 + 0 + 12.000 = 14.400 seconds, of which the stationary time is 16.7%. The 2.4 seconds a broadcast graphic shows is a sixth of the real loss
Two stops: 2 × 14.400 = 28.800 seconds
Halve the stationary time to 1.2 s and one stop still costs 13.200 s — a stop 50% quicker in the box is 8% cheaper overall, because the transit penalty does not move
Raise the limit to 100 km/h and the transit falls to 14.400 s, the penalty to 8.400 s and one stop to 10.800 s. The pit lane length and the limit do more to the answer than the stop does
The transit penalty by pit lane length, at the FIA’s 80 km/h
| Pit lane length (m) | At 80 km/h (s) | At 240 km/h (s) | Transit penalty (s) | With a 2.4 s stop (s) | Stationary share |
|---|---|---|---|---|---|
| 200 | 9.000 | 3.000 | 6.000 | 8.400 | 28.6% |
| 300 | 13.500 | 4.500 | 9.000 | 11.400 | 21.1% |
| 400 | 18.000 | 6.000 | 12.000 | 14.400 | 16.7% |
| 500 | 22.500 | 7.500 | 15.000 | 17.400 | 13.8% |
| 600 | 27.000 | 9.000 | 18.000 | 20.400 | 11.8% |
How little the stationary time changes the answer
| Stationary time (s) | Transit penalty (s) | Time lost at one stop (s) | Stationary share | Two stops (s) |
|---|---|---|---|---|
| 1.9 | 12.000 | 13.900 | 13.7% | 27.800 |
| 2.4 | 12.000 | 14.400 | 16.7% | 28.800 |
| 3.5 | 12.000 | 15.500 | 22.6% | 31.000 |
| 7.2 | 12.000 | 19.200 | 37.5% | 38.400 |
The stop is the small part of what a pit stop costs
This page is about motorsport — circuit racing in cars — whose international rules are the Fédération Internationale de l’Automobile’s: the International Sporting Code and its appendices for the sport as a whole, and a separate set of Sporting Regulations for each championship. Every figure below is printed with the regulation, the issue and the date it was read from, because motorsport regulations are not merely revised between seasons — they are reissued several times within a season and renumbered between editions, and a rule quoted without its issue will be wrong for somebody. The FIA published nine issues of the 2026 Formula 1 Sporting Regulations between October 2024 and October 2026.
A pit stop has a famous number attached to it — the stationary time, the two-point-something seconds a broadcast graphic flashes up — and that number is not what the stop cost. It is one of three components, and usually the smallest. The car also has to cross the pit lane at a speed limit, and the time that takes is only partly a loss, because the car would have covered that same stretch of road anyway. The loss is the difference: the transit at the limit minus the transit at racing speed. That difference is what this page computes, and it is the content of the page.
Work it at a round set of numbers. A 400 m pit lane at the FIA’s 80 km/h limit takes 18.000 seconds; the same 400 m at 240 km/h takes 6.000 seconds; the penalty is 12.000 seconds. Add a 2.4-second stop and one visit costs 14.400 seconds, of which the stationary time is 16.7%. Television showed you a sixth of the answer. And because the penalty contains no stationary time at all, it is identical for a brilliant stop and a fumbled one: halving the time in the box from 2.4 to 1.2 seconds makes the visit 8% cheaper, not 50%.
Both numbers that drive the penalty are inputs here, and that is not laziness. The pit lane speed limit is 80 km/h in Formula One — Article B1.6.3(a) of the 2026 Sporting Regulations, Issue 07 of 25 June 2026: “A speed limit of 80km/h will be imposed in the Pit Lane during the whole Competition”, the same figure that sits at Article 22.10 of the 2016 and 2019 editions — but the same article lets the Race Director amend it and other championships set their own. The pit lane length is harder still: it is not in the regulations, and it is not in the Race Director’s Competition Notes for the 2026 British Grand Prix either, which were read specifically to look for it. Several of that document’s items refer to “the image below”, so where a pit lane dimension is published at all it appears to be published as a drawing. This page asks you for it rather than inventing one.
Every circuit measurement on this page is an input, and the reason is that circuits differ and are resurfaced, relaid and relicensed. The lap distances used in the examples come from the FIA’s own List of FIA Licensed Circuits as updated on 31 March 2026, whose column is labelled “LAP DISTANCE (km)” — Silverstone 5.891 km, Monza 5.793 km, Spa-Francorchamps 7.004 km, Monaco 3.34 km — and each entry carries its own licence expiry, which is the clearest possible statement that the figure is dated. Put your own circuit’s figure in the field instead.
An honest note about article numbers. The same Formula 1 rule carries a different number in every edition of the regulations this batch read. The race distance is Article 5.3 in the 2016 and 2019 Sporting Regulations, Article 5.4 in the 2024 and 2025 editions, and Article B2.5.2 in the 2026 edition, which the FIA split into a Section A of general provisions and a Section B of sporting regulations and renumbered throughout. The championship points moved the other way: Article 6.4 from 2016 to 2025, then out of the Sporting Regulations altogether and into Section A at Article A2.2.1 for 2026. Quote a number here against the edition your own championship is run under, because the number alone will not find the rule.
The number this page cannot look up for you, it asks you for. The calculator has no table interpolation of any kind, and a curve fitted to stand in for a published table is worst at its extremes, which is exactly where the answer changes anything. These figures are also reissued: a circuit’s lap distance changes when it is relaid, a pit lane speed limit differs by series and has been amended by a Race Director for a single session, and a points scale has been rewritten inside a season. Anyone using one has it in front of them — on the regulations, on the circuit licence, in the event’s own notes — so the published value is the input.
Two things this page will not do. It will not tell you when to stop, how many times to stop or what to do with the answer: a stop’s cost is arithmetic and a strategy is a judgement. And it does not model the braking before the limit line or the acceleration after it, because no document read for this page gives a figure for either — the extra allowance field exists so you can add your own, and with it at zero the headline is a floor on the loss. For the lap time the stop interrupts, see the lap time and average speed calculator; for what a safety car does to the calculation’s whole premise, see the race suspension and virtual safety car interpreter.
Frequently asked questions
How much time does a pit stop cost in Formula 1?
Far more than the stationary time. With a 400 m pit lane at the FIA’s 80 km/h limit against 240 km/h on the track, the pit lane itself costs 12.000 seconds, so a 2.4-second stop costs 14.400 seconds in total. The real figure depends on your circuit’s pit lane length, which is why that is a field.
What is the pit lane speed limit?
80 km/h in Formula One. Article B1.6.3(a) of the 2026 Sporting Regulations, Issue 07 of 25 June 2026: “A speed limit of 80km/h will be imposed in the Pit Lane during the whole Competition”, and the Race Director may amend it. The same 80 km/h appears at Article 22.10 of the 2016 and 2019 editions, “during the whole Event”. Other championships publish their own limits.
Why is the whole pit lane transit not the time lost?
Because the car would have covered that ground anyway. Eighteen seconds at the limit over 400 m replaces six seconds at racing speed, so twelve seconds is lost, not eighteen. Counting the whole transit overstates the cost by half as much again.
Does a quicker stop save much?
Less than it looks. The transit penalty contains no stationary time, so it does not move. Halving the time in the box from 2.4 to 1.2 seconds takes one visit from 14.400 to 13.200 seconds — a 50% better stop for an 8% better outcome.
Where do I find my circuit’s pit lane length?
Not in anything read for this page. The FIA’s Sporting Regulations do not give it, the FIA’s licensed-circuits list gives only the lap distance, and the Race Director’s Competition Notes for the 2026 British Grand Prix give no pit lane length either. Where it is published it appears to be published as a drawing, so the field here takes your own figure.
