Split hotel costs
Hotels bill per room, but groups think per person. Convert between the two in a few taps.
Short answer
Split a hotel bill either per room (each room's occupants split that room's nightly rate) or per person overall, and add a single-supplement charge for anyone staying solo in a double room.

How it works
- 1Enter the total room charge, paid by whoever's card is on the booking.
- 2Split per room using custom amounts, or per person equally.
- 3Add extras with only the guests who used them.
- 4Settle before checkout.
Hotels bill per room, not per person, so a group with mixed room types (twins, doubles, a single) needs to convert the room-based invoice into fair individual shares.
The cleanest approach is to split each room's cost among its actual occupants, then add extras like breakfast or parking either per room or per person depending on how they were booked.
Solo travellers in a room built for two are often charged a single-supplement — that person absorbs the room's full cost rather than getting a half-share.
Worked examples with real numbers
Three rooms, mixed occupancy, three nights
Six friends book three twin rooms for 3 nights at 120/night each. One room ends up with only one occupant, who pays a 60/night single supplement on top.
| Room breakdown (3 nights) | Amount |
|---|---|
| Room 1 (2 guests): 120×3 | 360.00 |
| Room 2 (2 guests): 120×3 | 360.00 |
| Room 3 (1 guest + supplement): (120+60)×3 | 540.00 |
| Total | 1,260.00 |
| Person | Paid | Fair share | Balance |
|---|---|---|---|
| Room 1 guest A | 0.00 | 180.00 | −180.00 |
| Room 1 guest B | 0.00 | 180.00 | −180.00 |
| Room 2 guest C | 0.00 | 180.00 | −180.00 |
| Room 2 guest D (booker) | 1,260.00 | 180.00 | +1,080.00 |
| Room 3 guest E (solo) | 0.00 | 540.00 | −540.00 |
- Room 1 guest ARoom 2 guest D (booker)180.00
- Room 1 guest BRoom 2 guest D (booker)180.00
- Room 2 guest CRoom 2 guest D (booker)180.00
- Room 3 guest E (solo)Room 2 guest D (booker)540.00
Rooms 1 and 2 split evenly at 180 per person; the solo guest in room 3 covers the full 540 including the single supplement, since there's no roommate to share it with.
Per-person split with shared breakfast
Four people share one hotel room for 2 nights at 200/night, plus breakfast at 15/person/day for two people who opted in.
| What was billed | Amount |
|---|---|
| Room (4 people, 2 nights) | 400.00 |
| Breakfast (2 people, 2 days) | 60.00 |
| Total | 460.00 |
| Person | Paid | Fair share | Balance |
|---|---|---|---|
| Guest 1 (breakfast) | 0.00 | 130.00 | −130.00 |
| Guest 2 (breakfast) | 0.00 | 130.00 | −130.00 |
| Guest 3 (no breakfast) | 0.00 | 100.00 | −100.00 |
| Guest 4 (no breakfast, booker) | 460.00 | 100.00 | +360.00 |
- Guest 1 (breakfast)Guest 4 (no breakfast, booker)130.00
- Guest 2 (breakfast)Guest 4 (no breakfast, booker)130.00
- Guest 3 (no breakfast)Guest 4 (no breakfast, booker)100.00
Room cost 400 split four ways is 100 each; breakfast 60 split only between the two who ate it adds 30 each, bringing their totals to 130.
Turning room invoices into individual shares
1. Room total
nightly rate × nights (+ supplement if solo)
2. Per-occupant share
room total ÷ number of occupants in that room
3. Add shared extras
extra cost ÷ number of people who used it, added to their share
4. Person's total
room share + any extras they opted into
Per-room vs per-person splitting
| Method | Best for | Handles single supplements? |
|---|---|---|
| Per room | Groups with different room types or occupancy | Yes — add supplement to that room's total |
| Per person (flat) | Everyone shares identical rooms and rates | No — needs a manual adjustment |
Mistakes that cause arguments
Splitting the single supplement across the whole group
The supplement exists because one room has one occupant — it belongs to that person's bill, not everyone's.
Treating breakfast as a per-room cost
Breakfast is usually charged per guest per day — split it only among those who ate it.
Assuming rooms are equal when rates differ
If a group books different room grades, split each room's actual cost, not one blended average rate.
Practical tips
- Log each room as its own expense with just its occupants attached.
- Add the single supplement directly to the solo traveller's room cost, not the group total.
- Split optional extras like breakfast or parking by who used them, not by room.
- Have the booker collect the total in one settlement rather than per room.
Questions
- Per room or per person?
- Per room is the norm when room types differ; per person is fine when everyone has the same room.
- How do we handle a single supplement?
- Give the solo guest a custom amount equal to their actual room rate.
- What about incidentals on the master bill?
- Add each one as its own expense with the guests who incurred it.
