Restaurant Bill Calculator & Splitter Singapore
Add the 10% service charge and 9% GST to menu prices, then split the bill equally or by what each person ordered — every share adds up exactly.
Menu prices marked “++” get service charge and GST added. If you are splitting the total printed on the receipt, choose receipt totals.
Up to 20.
Dishes everyone shares are divided equally, then each person adds their own items.
Defaults are 10% service charge and 9% GST. Set the service charge to 0 if the restaurant does not charge one.
The bill
Service charge is added first, then GST is charged on that, so ++ prices are multiplied by 1.199.
In Singapore the 10% service charge is added to the food and drink total, and 9% GST is charged on top of that sum — so “++” prices cost about 19.9% more. Estimates only; the restaurant’s bill is final.
What each person pays
| Person | Pays | Items | Service | GST | Tip |
|---|---|---|---|---|---|
| Person 1 | $59.95 | $50.00 | $5.00 | $4.95 | $0.00 |
| Person 2 | $59.95 | $50.00 | $5.00 | $4.95 | $0.00 |
| Person 3 | $59.95 | $50.00 | $5.00 | $4.95 | $0.00 |
| Person 4 | $59.95 | $50.00 | $5.00 | $4.95 | $0.00 |
Shares are rounded to the cent so they add up exactly to the total. Other columns are rounded separately.
About this restaurant bill calculator
Menu prices in Singapore are often followed by “++”. That means a 10% service charge and 9% GST will be added to the bill. They are not added separately to the food: the service charge is added first, and GST is then charged on the food plus the service charge. The result is that a $100 menu total becomes $119.90, not $119.
This calculator does that sum for you and then helps you split it. Choose equal split when everyone shares everything, or by person when each person ordered different dishes: enter what each person had, add any dishes everyone shared, and every person’s service charge and GST are worked out on their own items.
Splitting a total into equal shares often leaves a cent over: $119.90 between three people is $39.9666…. This calculator gives two people $39.97 and one person $39.96, so the shares add up exactly to the bill and nobody has to guess who covers the extra cent.
If you are splitting the total already printed on the receipt, choose receipt totals: the calculator works backwards to the menu price and then splits the same way. You can also add an optional tip, and change the service charge or GST rate for places that charge differently.
How to use it
- Choose how to split: equally, or by what each person ordered.
- Say what the amounts are: menu prices (“++”) or the totals on the receipt.
- Enter the bill and number of people — or each person’s items and any shared dishes.
- Adjust the service charge, GST or tip if needed.
- Read what each person pays and the full breakdown.
Key terms and concepts
++ (plus plus): menu prices before the 10% service charge and 9% GST.
Service charge: a 10% charge restaurants add in place of a tip. It is itself subject to GST.
GST: 9% Goods and Services Tax, charged on food, drink and the service charge.
Nett price: a price that already includes service charge and GST, so nothing more is added.
Shared items: dishes or drinks split equally among everyone, however much each person ate.
Common use cases
- Splitting a dinner among friends who shared most dishes.
- Splitting fairly when one person only had a salad and a soft drink.
- Working out what a $200++ menu actually costs.
- Splitting a team lunch and adding a tip.
- Checking that a restaurant’s bill adds service charge and GST correctly.
Examples
Example 1 — $200++ among 4. Service charge $20, GST on $220 = $19.80, total $239.80, so $59.95 each.
Example 2 — $100++ among 3. Total $119.90: two people pay $39.97 and one pays $39.96.
Example 3 — by person. Four friends order $60, $45, $30 and $25 of their own food, and share $80 of dishes (each adds $20). Total $240++ becomes $287.76; the person who ordered $60 pays $95.92 and the one who ordered $25 pays $53.95.
Example 4 — splitting a receipt. A receipt total of $119.90 between two is $59.95 each — the calculator works back to a $100 menu price first.
Important notes
Rounding. Shares add up exactly to the total. The individual service charge, GST and tip columns are rounded on their own, so they may differ from a person’s total by a cent.
Tips. The optional tip is a percentage of food and drink before service charge and GST. Tipping on top of a service charge is optional.
Restaurants that differ. Some places charge no service charge, or charge GST only. Change the rates to match your bill.
Estimates only. The restaurant’s bill is the official amount.
Frequently asked questions
What does ++ mean on a menu in Singapore?
The price is before the 10% service charge and 9% GST. Both are added to your bill.
Is GST charged on the service charge?
Yes. The service charge is added to the food and drink first, and 9% GST is then charged on the total of both. A $100++ dish costs $119.90.
How much is $100++?
$119.90: $100 plus $10 service charge, plus 9% GST on $110, which is $9.90.
How do I split a bill when we ordered different things?
Use the “by what each person ordered” mode. Enter each person’s own items and any dishes everyone shared; service charge and GST are worked out on each person’s share.
Why do the shares not divide evenly?
A total like $119.90 does not divide into three equal cents. The calculator gives the extra cent to the shares with the largest remainder, so everything adds up exactly.
How do I split the total on the receipt?
Choose “receipt totals”. The calculator works back to the menu price and splits from there, so the shares add up to the printed total.
Do I have to tip as well as pay the service charge?
No. Tipping on top of a service charge is optional. The tip field is for those who want to add one.
Is this calculator exact?
It follows the standard sum for Singapore restaurants. The restaurant’s own bill is the official amount.
