SST calculator (Malaysia): add or remove SST
By the Lejar team · Updated
To add SST, multiply the price before tax by the rate: RM100 at 8% is RM8 of tax and RM108 in total. To take SST out of a price that includes it, divide by 1 plus the rate: RM108 / 1.08 = RM100 before tax. Service tax is 6% or 8%, and sales tax is 5% or 10%.
Enter an amount and a rate. Add SST to a price before tax, or take SST out of a price that already includes it.
Your result
SST RM8.00 at 8%
- Before SST
- RM100.00
- SST 8%
- RM8.00
- Total
- RM108.00
