Any of these sound familiar?
Don't let tedious money calculations ruin a great memory.
We took two cars, but only three people rode in mine.
Group your participants by car! FAMI-KAN lets you split specific receipts (like a toll or gas) ONLY among the people who rode in that specific vehicle.
I bought all the snacks, but they paid for the Airbnb.
Just log both expenses. The algorithm instantly calculates the net difference and tells exactly who needs to Venmo whom.

Why we built FAMI-KAN
At the end of a fun trip, the worst part is figuring out who owes what. Pulling out receipts, calculating, and remembering who paid for what brings a cold, administrative feel to great memories.
Existing split-bill apps are useful, but often too complex or force everyone to download an app. We wanted something simpler and more welcoming.
FAMI-KAN is not just a calculator. By letting the system handle the math, you can focus on the fun conversations and memories. It's a partner that preserves the joyful afterglow of your events.
Frequently Asked Questions
Enter each car's passenger count and gas cost into FAMI-KAN, and it auto-calculates per-person shares. Works for multiple cars with different passenger counts. Log each gas stop as it happens so settlement after the trip is effortless.
Create groups per car and split by passenger ratio, or choose an even split across all riders. Tolls and rental fees are tracked as separate line items and auto-totaled in the final settlement. You can mix per-car splits for tolls with even splits for lodging in the same event.
Enter the rental cost under the payer who booked it, then set all riders as participants. It auto-splits evenly. Insurance and add-on fees can be logged separately and are combined in the final settlement, so you can enter the rental invoice as-is.
Use weighted ratios to reflect the driver's contribution. Lower their share weight or apply a negative offset to credit them for driving. For example, you can easily set a '$20 driver discount' that's automatically reflected in the final settlement.
Set the driver's weight lower than other members — e.g., driver at 0.5 and passengers at 1.0 halves the driver's share. Alternatively, apply a fixed dollar credit as a 'thank you for driving' offset. Either method is auto-reflected in the final settlement.
Yes. Add each expense under the same event with different categories. FAMI-KAN nets everything and shows one final 'who owes whom' summary. Rest stop meals, souvenirs, and all other trip expenses can be managed in one place.
You can set different participants per expense item. For example, 'Day 2 lunch includes late-joiner C' or 'Day 3 hotel excludes B'. Adjusting per-item participants ensures accurate proportional calculations.
Log expenses in real-time as they happen and share the URL so everyone can see running totals. Putting off the math until after the trip often leads to lost receipts and forgotten amounts. Create the event before you leave and share the link upfront.
No. FAMI-KAN runs entirely in your browser. Share a URL with your travel companions and everyone can access it instantly. Completely free with no upsells. Works on iPhone, Android, and desktop browsers alike. Use it for weekend drives or month-long trips.
Event data is stored on the server until you delete it. You can revisit the shared URL anytime after your trip to review the settlement. It's handy when you want to look back and see 'how much did that road trip actually cost?'
