Common split scenarios
Real situations where groups get stuck on the math. Load any example to see how it works.
Single room supplement
Three couples and one solo traveler book a resort. The solo traveler gets their own room and pays a supplement. The couples split room costs equally.
Deposit already paid
One person put down a 300 deposit for the whole group. Everyone else needs to reimburse them, so their final share is reduced.
Hostel bunks vs private room
Five friends book a hostel. Two get a private room, three take bunks in a shared dorm. The private room costs more per night.

How to split group costs fairly
Start with the full cost
Enter the total amount from your booking confirmation. Include taxes and fees if they are part of the final charge. If you are splitting a deposit separately, use the deposit amount as the total and save the final payment for a second split.
Count nights, not just heads
A person staying 3 nights out of a 7-night trip should not pay the same as someone there the whole time. Use the "Nights stayed" field to weight each share. The calculator does the math so you do not have to.
Handle room differences
If one room costs more (bigger bed, ocean view, private bath), add the difference as an adjustment for the person or couple in that room. Everyone else splits the base cost equally.
Account for deposits and credits
If someone already paid part of the booking, enter that as a negative adjustment. Their final share goes down and everyone else picks up the difference. This keeps things fair without needing a separate reimbursement step.
Share the result

Common mistakes to avoid
Do not forget cleaning fees, service charges, or resort fees. These are part of the total cost and should be split too. Also, do not ignore partial stays. Even one night less makes a difference over a large group.
