Turkey trip cost calculator: distance, fuel and tolls on one receipt

Multiply the distance by your consumption per 100 km, divide by 100 and multiply by the pump price: 453 km × 7.5 ÷ 100 × 80.38 = ₺2,730.91. Then add the bridge tolls (price per crossing times the number of crossings) and any motorway tolls, and divide the total by the people sharing the car. The calculator above does all of it and prints every line with its source.

Istanbul to Ankara is 453 km in the table of the General Directorate of Highways (KGM) dated 3 March 2026. The same table gives Istanbul – Izmir 566 km, Istanbul – Antalya 715 km, Ankara – Izmir 586 km. All 81 provinces are in the distance table above.

The table gives 453 km. A petrol car using 7.5 L/100 km pays about ₺2,731 for fuel one way at ₺80.38 a litre (OPET list price in Istanbul on 30 Sept 2026); a diesel car using 6 L/100 km at ₺93.40 pays about ₺2,539. A return trip doubles both. Add the bridge tolls on your route and any motorway tolls, then divide by the passengers: the calculator does it with your own car.

They are KGM’s official road distances between the centres of the provinces (table of 3 March 2026), not door to door. Your actual route, a detour or a city centre can add or remove kilometres, and the table carries no travel time, so this page shows none.

For petrol (95 octane) and diesel, the OPET list price of the start city as read on 30 September 2026; you can switch to the destination or the Turkey average, or type your own price. A station can charge a few lira more or less, and the data can trail the stations by a day or more. There is no official LPG price here, so you enter it. For an electric car the page uses the operators’ published tariffs with their check date when it has fresh ones, otherwise your own price per kWh.

For a car (class 1), per crossing, VAT included: 15 July Martyrs Bridge ₺59.00 (from 1 Jan 2026); Fatih Sultan Mehmet Bridge ₺59.00 (from 1 Jan 2026); Osmangazi Bridge ₺1,170.00 (from 1 Jul 2026); Yavuz Sultan Selim Bridge ₺110.00 (from 1 Jul 2026); 1915 Çanakkale Bridge ₺1,170.00 (from 1 Jul 2026). Amounts for other vehicle classes are in the tariff table above. KGM publishes each tariff as a PDF, and the table shows the day each one took effect.

KGM’s tariff for the 15 July Martyrs, Fatih Sultan Mehmet and Yavuz Sultan Selim bridges says both directions are charged. The Osmangazi and 1915 Çanakkale tariffs do not say. For a return trip the calculator counts two crossings for every bridge you tick, and you can change the count with the plus and minus buttons.

Most cars are class 1: two axles with an axle spacing under 3.20 m. Class 2 is two axles with 3.20 m or more, class 3 three axles, class 4 four and five axles, class 5 six or more, class 6 motorcycles. The class sets the price only: which vehicles may use which Bosphorus bridge is decided by Istanbul’s transport coordination centre (UKOME), so check the current rule before you plan a crossing.

No. The data holds the five toll bridges but not the motorway tolls, and it does not know which roads your route takes. Look up your trip in KGM’s toll query, add up the amount and type it in “other tolls”: it then joins the total and is split between the passengers.

It is a planning figure. The kilometres are the official table’s, the prices are the day’s list prices and tariffs, and the consumption is yours. Real trips differ with the route, speed, load, air conditioning, traffic and the price at the station where you fill up. Keep a margin, especially for long trips.
