HOW THE WORKSHEET CALCULATES
One transparent formula, with no hidden assumptions.
Per-traveler costs
Return ticket plus required baggage and seat fees, multiplied by the number of travelers. Enter the amount for both directions when the seller prices extras per segment.
Shared costs
Home-airport transport, destination transfers, parking, tolls, required overnight accommodation, and other known costs are added once for the whole traveling party.
What is deliberately excluded
The tool does not estimate future price changes, disruption risk, exchange rates, or the value of your time. Verify every amount with the relevant airline, seller, airport, hotel, or transport provider.
