Adding 9% GST (Singapore) to your net amount.
How to add 9% GST
Multiply the net amount by 0.09 to get the GST, then add it on. For example, 1,000.00 SGD net + 90.00 SGD GST = 1,090.00 SGD gross.
How to remove GST from a price
Divide the GST-inclusive amount by 1.09. For example, 1,000.00 SGD including GST ÷ 1.09 = 917.43 SGD net, so the GST is 82.57 SGD. Subtracting 9% of the gross instead would give 910.00 SGD, which understates the net amount. It's the most common GST mistake.

About GST in Singapore
GST (goods and services tax) is a consumption tax charged on most goods and services. It works the same way as VAT: businesses charge it on their sales and generally claim credits for the GST they pay on purchases.
The standard rate in Singapore is 9%, charged in SGD. Reduced or zero rates may apply to some goods and services. Use the calculator's custom rate for those, and confirm current rates with the tax authority before you file.
