Split a real trip → open Duesy
On a group trip, everyone ends up paying for something — one person books the hotel, another covers dinner, a third grabs the taxis. By the end nobody remembers who's ahead. This calculator adds it all up, works out each person's fair share, and reduces the tangle of who-owes-who into the fewest payments possible.
The catch on a real trip is currencies: a hotel in AED, meals in SAR, taxis in PKR. This free tool works in one currency at a time. Duesy stores every expense in its original currency and converts with live rates, so a mixed-currency trip settles correctly — and everyone can add expenses from their own phone as the trip happens, instead of one person keeping a spreadsheet. It's free, and friends join by link or QR.
Just splitting one bill? Use the bill split calculator or the tip calculator. Sharing a house? See the rent split calculator. Comparing apps? Read about Duesy as a Splitwise alternative or how to split bills on a trip.
Add everyone, then log each expense with who paid and the amount. Total the shared costs, divide by the number of people for each person's fair share, then compare it to what each person actually paid. Whoever paid less than their share owes the difference. This calculator does all of that and finds the fewest payments to make everyone even.
With several payers, people usually owe each other in a tangled web. Simplification cancels those out into the smallest set of payments — instead of six transfers you might only need two. The settle-up list here is already simplified.
This free calculator works in one currency at a time. Real trips mix currencies, so Duesy stores each expense in its original currency and converts with live rates for a correct settlement.
Yes, completely free with no sign-up. Duesy is also free for splitting expenses and tracking who owes who across a whole trip.
