What is the best way to track expenses when currencies differ?

Select one base currency for the group trip (e.g., USD or EUR). Convert all local currency transactions to the base currency using the exchange rate on the purchase day or the cash exchange rate the group received.

How does DeliBabki handle multiple currencies?

In DeliBabki the currency is set once for the whole group and expenses are recorded in it. On a trip the practical approach is to agree one fixed rate for the whole route, enter amounts already converted, and note the original local amount in the expense description. Automatic per-transaction conversion is still planned.

Multi-Currency Expenses: How to Calculate Travel Debts in Different Currencies

How to split costs when paying in Lira, Euros, Rubles, or Dollars on the same trip.

Published: July 17, 2026

Traveling abroad with friends is an adventure, but sorting out the final expenses can feel like homework. Tickets are bought in your home currency, the hotel is booked in Euros, cabs are paid in local cash (like Liras or Drams), and dinner tips are left in Dollars. How do you sum all this up to find out who owes whom?

Rule 1: Choose a Base Currency for the Trip

Avoid settling balances for each currency separately. This leads to confusing scenarios like "Anna owes Boris 15 Euros, while Boris owes Anna 1200 Rubles." Pick a single base currency for the group — usually your home currency or the major currency used on the trip (like USD or EUR).

Rule 2: Determine Your Conversion Strategy

There are two common ways to handle conversion:

Fixed cash exchange rate: If the group exchanged a lump sum of cash, use that exact conversion rate for all cash expenses.
Live API rates: Modern tracker apps pull currency rates automatically on the day of the transaction, saving you the math.

Running a Multi-Currency Trip in DeliBabki

In DeliBabki the currency is chosen once, for the whole group, and every expense lives in it. There is no automatic per-purchase conversion today — it is planned — so the working approach is to agree one fixed rate at the start of the trip, enter amounts already converted, and put the original sum in liras or drams in the description, which keeps the receipt traceable.

A fixed rate is not a compromise here but a deliberate choice: with the rate of the day the same expense changes weight over time and debts stop reconciling when people repay. Fold the bank fee straight into the rate by taking one 1–2% worse than the market.

Convert the Expense List

Enter each expense with the rate your group agreed on:
