Q.

Family A fronted the hotel, Family B paid for dinner... who owes who?

A.

Just share the link and everyone enters what they paid. If you set ratios like 'Adult 1.0, Child 0.5, Infant 0', the system calculates the exact balance instantly, whether you're 4 or 40 people.

Q.

Why am I paying a full adult share for my toddler's meal?

A.

You can freely adjust the 'burden ratio' for each participant. Baby eats for 0, toddler for 0.3, dad for 1.0—fair amounts are automatically calculated based on your family's reality.

Q.

The group chat turns into a stressful accounting thread for a week...

A.

Once everyone logs their payments, one tap shows exactly 'Who sends what to whom'. Share the final receipt link and settle up instantly. No more awkward math text chains.

FAMI-KAN needs no sign-up and no install. Set a ratio once — Adult 1.0, Child 0.5 — and it applies to every expense after that. We compare it with other apps, including where they do better.

Why FAMI-KAN is Best

The trickiest part of splitting expenses on a multi-family vacation or group camping trip is when the number of adults and children's ages vary wildly between families. Adults drink alcohol and enjoy full-course meals while toddlers barely eat anything — yet splitting the bill evenly creates a real sense of unfairness. With FAMI-KAN, you can set a different burden ratio for every participant (e.g. Adult 1.0, School-age child 0.5, Infant 0), and the app automatically factors in every advance payment and reimbursement across accommodation, meals, and activities to calculate the simplest possible settlement — who should send how much to whom — in a single tap. No spreadsheets, no calculators, no group-chat arguments. FAMI-KAN also supports deposits (pre-collected funds), so you can combine upfront contributions with post-trip settlements seamlessly. Whether your group is 4 people or 40, fair and transparent expense splitting is just one shared URL away.

Simple 3-Step Guide

No app downloads or accounts needed.

  1. 1

    Create the trip

    Start an event, name it and choose the currency. Pick a categories pattern for adults and kids, or set your own, such as Adult 1.0, Child 0.5, Infant 0.

  2. 2

    Add each family

    Register each family as a member and set how many adults, kids and infants it brings. The family's total ratio is calculated automatically.

  3. 3

    Log expenses as you go

    Share the link so whoever pays for lodging, groceries or tickets enters it from their own phone. Untick any family that wasn't part of an expense.

  4. 4

    Settle once at the end

    Open the Settle tab to see who pays whom in the fewest transfers, then share the link or send a postcard image to the family chat.

Why we built FAMI-KAN

FAMI-KAN isn't just a calculator. It's a partner that handles the math so you can focus on what matters: "That dinner was amazing", "Where should we go next?" — preserving the afterglow of time well spent together.

The worst part of any trip comes at the very end — when everyone's tired and someone has to sort out the money. Lining up receipts, punching numbers into a calculator, trying to remember who paid what... it brings a cold, transactional feeling to what should be warm memories.

Existing apps are useful, but often too complex or require everyone to install the same app. For family gatherings spanning multiple generations, we needed something simpler — and warmer.

Frequently Asked Questions

Half is an easy starting point, but you can pick any ratio that matches how much the kids actually use. For example, with Adult 1.0, Child 0.5 and Infant 0, Family A (2 adults, 2 kids) has a weight of 3.0 and Family B (2 adults, 1 infant) has 2.0. On an $1,800 cabin, Family A pays $1,080 and Family B pays $720.

Either works. Register each family as one member and enter how many adults, kids and infants it brings, and the family's weight is added up for you (2 adults and 1 child at 0.5 is 2.5). The settlement then shows one transfer per family instead of one per person.

Yes. Keep Adult 1.0 and Child 0.5 for groceries and restaurants, and on the lodging payment use "Change shares for this payment only" to give each family the same ratio regardless of size. Every other expense keeps the age-based split.

Untick them under "Target Members" on the lodging and meals from the nights they missed. They share only the expenses they were part of, and the adult and child ratios still apply among the families who were there.

Record each family's contribution with "Give to Organizer", and when the organizer pays for groceries or tickets from that pool, choose "Organizer pays". At the end, the settlement shows any refund due from the organizer or any shortfall still to collect.

Yes. Duplicate the event from the history on the home page. The families, the adult and kid categories and the currency carry over, and the expenses start empty.

Enter the tickets with every family under "Target Members", and the paid pass with only the families who used it. If you'd rather split the tickets by what each family's tickets actually cost instead of by ratio, open "Change shares for this payment only" and set a fixed amount for each family.

Yes. Every bill-splitting and settlement feature is free to use, and no registration is required.

No. It runs entirely in your web browser. Just share the link and everyone can access it immediately on their phones.

Yes, you can select the currency when creating an event (almost every official currency in the world). You can unify calculations easily for trips abroad.

Yes. You can switch between three views — "Settlement", "By Member" and "By Item". You can see what each person paid and owes, and for any single expense, who is covering how much. Everyone sees why the number is what it is, on the same screen.
