GST is calculated by multiplying the base price of goods or services by the applicable GST rate percentage (e.g., 100 × 10 % = $ 10 1 0 0 × 1 0 % = $ 1 0 GST). To add GST, multiply the base amount by ( 1 + rate ) ( 1 + r a t e ) . To remove GST, divide the inclusive price by ( 1 + rate ) ( 1 + r a t e ) . Common rates are 5%, 12%, 18%, or 28%.
