How do I work out the event cost per person?
Add every cost, then divide the total by the number of people who share it. A cost charged per person, such as a ticket, is multiplied by the number of people going. A cost for the whole group, such as a room, is added once. Our illustration, with invented prices: seven guests and the organiser share a room at S$65.00 for the whole group and food at S$15.50 per person. Food is 8 × S$15.50 = S$124.00, the total is S$189.00, and S$189.00 ÷ 8 = S$23.625 each before rounding.
How does the calculator round, and who keeps the surplus?
The tool’s convention is to round each share up to the next cent, so the organiser is never short. In the example each person pays S$23.63. The seven guests pay S$165.41 in all, and the organiser, who pays the S$189.00 bill, is left with S$23.59: 4 cents below an equal share. Rounding up means 8 × S$23.63 = S$189.04, which is 4 cents more than the cost. That difference is the rounding surplus. It is always under one cent for each person paying, and it never goes the other way.
Should the organiser pay a share?
That is your choice, and the tool offers three settings. If you go and pay the same as everyone else, the cost is split between the guests and you, and your own share is what is left after you collect. If you go but the guests also cover your share, as with a birthday host, the cost is split between the guests alone: in the example S$189.00 ÷ 7 = S$27.00 each. If you are only booking and collecting, per-person items count the guests only.
How do I enter a booking fee or other per-order fee?
Use the fee section for a charge made once per order, and enter what your own checkout shows and how many orders you will place. The tool multiplies the two. It never fills in a fee for you. A fee charged per ticket belongs in a per-person line instead, as in our worked example of ticket booking fees for a group of six.
Where do I find the prices to enter?
The prices come from you. The calculator holds none of its own, and venue and ticket prices change, so read them from the seller’s page on the day you book. Two of our guides show where to find official prices: Gardens by the Bay ticket combinations and group cost and park venue hire rooms and rates compared. To decide how many portions to price, see how much food to order for a party.
What does this calculator not do?
It splits the total equally and nothing else. If drinks, dietary choices or children’s prices make the orders uneven, our guide to splitting the bill fairly covers other methods. It does not add GST, service charge or any other charge, so enter each price as your checkout shows it. It does not handle deposits, cancellations or refunds, and it does not collect money. It does not check the prices you type.
Common questions
How do I split a group cost fairly?
Agree what is included and who pays first, add every cost, then divide the total by the number of people sharing it. Whole-group costs are added once and per-person costs are multiplied by the head count.
Why do the shares add up to a few cents more than the cost?
Each share is rounded up to the next cent so the organiser is never short. The extra, shown as the rounding surplus, is under one cent for each person paying.
Can the organiser’s share be nothing?
Yes. Choose the setting where the guests’ shares also cover yours, or the one where you are only booking and collecting.
Is anything I type sent anywhere?
No. The sums are worked out in your browser.
