How our airport fare estimates work

AirportFareGuide is a planning tool, not a taxi operator or booking service. We show a useful fare range and make the assumptions visible so you can compare options before confirming a live price.

Core calculation

The fare formula

Estimated fare = base fare + distance rate + selected airport/toll charges + selected supplements

The calculator then displays a lower and upper planning range around that result because real taxi prices can vary by operator, traffic, local regulation and demand.

Fare reference data

Each airport record contains a reference base fare, per-kilometre rate and airport access amount in local currency. These figures are planning references rather than guaranteed operator quotes.

Route distance

When you select an address or postcode, road distance is requested from OpenStreetMap-compatible routing services. Preset or manually adjusted distances are clearly identified when a routed location is not selected.

Vehicle and supplements

Vehicle class applies a visible multiplier. Luggage, night travel, estimated tolls and airport entry charges are included only when their calculator options are selected.

Currency conversion

Currency rates are requested from a third-party exchange-rate API when the page loads. If that service is unavailable, the calculator continues with bundled fallback rates and labels the result accordingly.

What may be included

  • Reference flag-drop or base fare
  • Distance-based charge
  • Selected vehicle-class multiplier
  • Selected luggage and night supplements
  • Selected estimated toll and airport-entry amounts

Always verify separately

  • Road closures, special-event pricing and detours
  • Child seats, accessibility requests and oversized luggage
  • Local tariff changes introduced after our review
Sources and corrections

How to use the result responsibly

Use the calculator to set a budget and compare transport choices. Before travelling, confirm the current fare, airport access rules and payment conditions with the airport authority or your chosen licensed operator.

If you find outdated airport information, please send the page, airport code and an official source link. We use correction reports to prioritize the next data review.
