Frequently Asked Questions

Everything you need to know about the Expense Splitter

How does the expense splitting algorithm work?

Each expense is split equally among all group members. The tool tracks how much each person has paid vs. their fair share. It then uses a greedy algorithm to calculate the minimal number of settlement payments — so instead of everyone paying everyone, you get the fewest transfers needed to balance all debts.

Is my expense data saved securely?

Yes — all data is stored locally in your browser's localStorage. Nothing is sent to any server. Your expense data persists between visits, so you can close the page and come back later. Use the "Reset All Data" button to clear everything when your trip is over.

Can I split expenses unevenly?

Currently, all expenses are split equally among all group members. If someone didn't participate in a particular expense, you can adjust by adding a separate entry for just those members or splitting the difference manually. Future updates may include custom split options.

What types of expenses can I log?

You can log any shared travel expense — hotel stays, restaurant meals, taxi fares, museum tickets, groceries, tours, or anything else. Simply enter a descriptive title, the amount in your preferred currency, and who paid for it.

How many people can I add to the group?

There's no limit! Add as many group members as needed. The settlement algorithm efficiently handles any group size. Three default members (Alex, Taylor, Jordan) are pre-loaded for easy testing — you can remove them and add your own names.

Debt Minimization Graph Algorithms, Multi-Currency Group Splitting, and Fair Travel Settlement

📊

Executive Summary & Overview Traveling with a group of friends or family creates unforgettable memories, but managing shared finances—who paid for the rental car, who covered the group dinner, and who bought the airport snacks—often causes confusion and awkward post-trip disputes. Our Group Trip Expense Splitter utilizes advanced debt minimization algorithms to track group spending, calculate fair per-person shares, and determine the exact minimum number of payment transfers required to settle all debts.

1. How Debt Minimization Algorithms Simplify Group Settlement

In a group of 6 travelers logging 25 shared expenses, naive calculation would require dozens of confusing peer-to-peer transfers. Our engine calculates each person's net balance (Total Paid minus Total Fair Share) and executes a greedy bipartite matching algorithm to resolve all group balances with the absolute fewest payment transactions possible.

2. Handling Unequal Splits & Shared Group Purchases

Not all group expenses are split equally:

• Shared Lodging: Split equally across all room occupants.

• Group Rental Car & Fuel: Split equally across all vehicle passengers.

• Dinners & Alcohol: For fair splitting when alcohol consumption varies, log shared food platters together while having heavy drinkers cover premium cocktail rounds separately.

3. Multi-Currency Group Expense Tracking

On multi-country group trips, expenses are logged in various local currencies. Our system converts all transactions into a single unified settlement currency using live daily exchange rates, ensuring nobody loses money to exchange rate confusion.

4. Golden Rules for Friction-Free Group Travel Finances

Establish financial clarity before departure: (1) Appoint a single person to log receipts daily in the splitter app; (2) Take smartphone photos of all paper restaurant bills; and (3) Settle all balances via instant digital payment apps (Venmo, Revolut, Zelle, Wise) within 48 hours of trip completion.
