New tool: is the Gautrain or driving cheaper to OR Tambo?

I have added another free tool, this one settles an argument I have with myself every time I fly out of OR Tambo. Do I take the Gautrain, or do I drive and pay for long stay parking?

It is harder to work out than it sounds, because the two are priced in completely different ways. The Gautrain charges every passenger a separate fare, while driving and parking is one price no matter how many people are in the car. So the cheaper option flips depending on how many of you are going and how long you will be away.

The tool does the full sum both ways. On the driving side it counts the petrol there and back plus the real ACSA long stay parking tariff. On the train side it counts every fare, plus whatever it takes to get to the station, whether you drive and park there at the cheap rail user rate, get dropped off, or take an e-hailing trip. Then it tells you which one wins, by how much, and the point where the answer would flip.

A few things I tried to get right.

It uses the official numbers. Gautrain fares to the airport are fixed per station, R228 from Sandton, R240 from Rosebank or Park, R258 from Pretoria or Centurion, one way per person. Parking is the published ACSA OR Tambo tariff for 2025 to 2026.

It surfaces a genuine parking quirk. At OR Tambo, three days of long stay parking costs about R540, but a full four days is only about R288, because the long stay discount only kicks in on day four. If your trip is right on that line, it can actually be cheaper to be charged for the extra day, and the tool flags it.

It is honest about the things money does not show. The airport train does not run late into the night, so a midnight landing rules it out and you will need a lift or an e-hailing trip home. Heavy bags and small children make driving to the terminal door easier even when it costs a bit more. On the other hand the train sails past the airport traffic and runs to a timetable.

As a rough guide, one person on a longer trip usually does best on the Gautrain, while two, three or four people, or a quick turnaround, usually tip it back to driving and parking.

Almost everything runs in your browser, and nothing is saved. The only thing that leaves your device is the optional use my location button on the driving tab, which sends your location once to a maps routing service to work out the road distance to the airport, and nothing is stored. If you spot a fare or a parking rate that has changed, tell me and I will update it. Which way do you usually get to OR Tambo?

This is something every teacher going to a conference needs to calculate properly. I always just guessed and probably paid more than I should have over the years.

Update: the tool now does Ubers too

A quick update on this one. Alongside the Gautrain and driving, the tool now works out a full Uber to OR Tambo as a third option, so it does the sum all three ways.

The Uber side estimates the fare from your distance at the usual Joburg and Pretoria uberX rate, counts the trip both ways, and because it is one car the whole party shares the cost. There is a tick box for busy times that adds a rough surge, and the figure is editable, so if you have a real in-app quote you can drop it straight in.

Roughly how it falls out: an Uber is one flat fare for the car with no parking bill, so it comes into its own when there are a few of you, which stacks up the train’s per person fares, and you are away long enough that parking would otherwise be steep. For a single traveller it is usually the dearest of the three, because the run to the airport is a long one and there is nobody to split it with. The verdict and the cards update live, so you can find the crossover for your own trip.

One honest caveat I kept in: a late landing can make the ride home dearer or harder to get, and a big group may need a pricier larger vehicle, so treat the Uber figure as a guide rather than a quote.

Daniel this is the kind of maths that actually matters, nice one. Adding Uber as the third option is clever, because most of us just feel like one is cheaper without ever doing the sum properly. From my side in Soweto, the Gautrain only makes sense when I’m flying solo. The moment it’s me plus two okes heading to a flight, that per passenger fare adds up fast and driving with long stay parking starts winning, even with the petrol. Uber I mostly use late at night when I don’t wanna leave my car standing for a week. One thing though, does the tool let you adjust for if someone drops you off for free? That’s the real hack many of us use. What inputs are people finding change the answer most?

Thanks Sipho, glad it lands for you, and that is the whole point of it, do the sum instead of going on a feeling.

On the drop-off question, the answer is yes for one half of the trip and not yet for the other, and you have put your finger on a real gap. For the Gautrain side there is already an option under “Getting to the Gautrain station” called “Someone drops me off (free)”, which zeroes that leg out so it is just the train fares. What the tool does not yet do is the bigger version you are describing, someone running you all the way to OR Tambo and fetching you, so there is no parking and no train at all. Right now the drive option always assumes you park. That is a fair fourth scenario to add, a free lift to the terminal, and I will look at building it in.

On which inputs move the answer most, two of them do nearly all the work. The first is the number of travellers, because the Gautrain charges every person separately while the car and the Uber are one price for the whole party, so each extra head pushes the train up and leaves driving and Uber flat. The second is the days your car is parked, since ACSA parking is where the drive cost really climbs, and that is the input with the odd step where four days can come in under three. After those two it is the distance and fuel price on the drive side, and the surge tick on the Uber side, but those nudge the figure rather than flip the verdict.

So if you want to see the winner change under your hands, drag the travellers and the days first. Solo for a short trip and the train tends to win, a carful for a long stay and driving or an Uber usually takes it.
