A Singapore tipping guide and calculator that reflects how things actually work here: tipping is not customary. Most full-service restaurants and hotels already add a 10% service charge (plus 9% GST), which serves as the gratuity, so anything extra is entirely optional. The tool computes the real total and splits it per person.
How it works
The calculator picks a service-charge convention from the setting you choose, then layers GST and any optional tip:
service charge = bill * 10% (restaurants, hotels, salons; 0% for hawker, taxi)
subtotal = bill + service charge
GST = subtotal * 9% (if enabled)
extra tip = bill * (your %) (optional, default 0)
total = subtotal + GST + extra tip
per person = total / number of people
For hawker centres, casual cafes and taxis the service charge is 0% and no tip is expected — you simply pay the stated price (rounding a fare up at most).
Example and notes
A 80 SGD restaurant bill for 2 people with the default settings: a S$8.00 service charge, S$7.92 GST on the S$88 subtotal, no extra tip, for a S$95.92 total — about S$47.96 each.
The headline takeaway: in Singapore you almost never need to tip. Where a service charge appears, it is the gratuity. All figures are calculated locally in your browser.
