How to use this SST calculator
- Start by entering an amount in Single amount mode. For separate items with their own quantities and rates, select Multiple items and enter a quantity and unit price for each row.
- Choose Add SST if your prices exclude SST. Choose Remove SST if your prices already include it. This choice applies to all items.
- In Multiple items mode, use Add item for the next row. Leave an unfinished row blank until you are ready to enter its price.
- Choose the product or service category for each amount. If you select a manual category, enter the percentage you want to use.
- Review the breakdown, then use Copy result or Print result to keep a copy. Complete every item before copying or printing the combined total.
How to add or remove SST
These examples use 8% to show the calculation. Use the rate that applies to your item. The percentage formulas below do not apply to a fixed-amount tax.
Add SST to a price before tax
For an amount of RM1,000 before SST at an example rate of 8%, choose Add SST and enter 1000.
- SST amount
- RM1,000 × 0.08 = RM80
- Total including SST
- RM1,000 + RM80 = RM1,080
SST amount = amount before SST × (rate ÷ 100)
Remove SST from a price including tax
For a total of RM1,080 that already includes 8% SST, choose Remove SST and enter 1080.
- Amount before SST
- RM1,080 ÷ 1.08 = RM1,000
- SST amount
- RM1,080 − RM1,000 = RM80
Amount before SST = total including SST ÷ (1 + rate ÷ 100)
To remove 8% SST, divide by 1.08. Subtracting 8% from RM1,080 would give RM993.60, which is not the original RM1,000 price. The tax was calculated on the price before SST.
Calculate several items with different SST rates
Select Multiple items when you need separate amounts or rates. Each row's amount is its quantity multiplied by its unit price. The calculator applies that row's SST rate, rounds its amounts to two decimal places, then adds the rows together.
For example, suppose you have two RM100 items at 8% and three RM50 items at 5%. In Add SST mode, the breakdown is:
| Items | Before SST | Rate | SST | Including SST |
|---|---|---|---|---|
| 2 × RM100 | RM200.00 | 8% | RM16.00 | RM216.00 |
| 3 × RM50 | RM150.00 | 5% | RM7.50 | RM157.50 |
| Combined total | RM350.00 | Mixed | RM23.50 | RM373.50 |
Use a separate row for each rate, rather than applying one rate to the RM350 subtotal. In Remove SST mode, enter each item's unit price including SST. Because amounts are rounded per row, combining items into one row can produce a small rounding difference.
Which SST category should you choose?
SST includes sales tax and service tax. Sales tax generally applies to taxable imported or locally manufactured goods. Service tax applies to prescribed taxable services. The treatment depends on your item and the applicable rules, rather than one percentage for every purchase.
The calculator offers preset percentages of 0%, 5%, 6%, 8%, and 10%, plus a manual percentage option. They are calculation choices, not a complete list of Malaysian SST treatments. Choosing the exempt or 0% option does not confirm that your goods qualify for an exemption.
The credit or charge card option uses a fixed RM25 per unit in this calculator. In Multiple items mode, its fixed tax is RM25 multiplied by quantity, rather than a percentage of the price. This fixed option requires MYR; enter prices in ringgit. Changing the selected currency does not convert your entered amounts. Check the official card guidance for when the tax applies.
Before using an estimate on an invoice or return, confirm the taxable category, rate, and any exemption using the Royal Malaysian Customs Department (RMCD) guidance. For help with registration, read our SST registration guide.

SST Calculator Malaysia FAQs
What is an SST calculator used for?
An SST calculator helps you estimate the SST amount, the total including SST, or the amount before SST. It is useful when checking invoice amounts, quotations, and simple business records.
How do I calculate SST from an amount before tax?
For percentage SST, multiply the amount before SST by the rate divided by 100. Then add that tax amount to the original amount to get the total including SST. The fixed RM25 option uses a fixed amount instead of this percentage formula.
How do I remove SST from a total that already includes SST?
For percentage SST, divide the SST-inclusive total by 1 plus the rate divided by 100. For example, with 8% SST, divide the total by 1.08 to estimate the amount before SST. For a fixed-amount tax, remove the fixed tax amount instead.
What SST rate should I use in Malaysia?
Choose the category and rate that apply to your item. The calculator has preset percentages, a manual percentage option, and a fixed RM25 option. These choices do not cover every SST treatment or confirm whether your item is taxable. Check the current MySST industry guides and tax orders before selecting a rate.
Can I calculate several items with different SST rates?
Yes. Select Multiple items, enter each item's quantity and unit price, and choose its SST category or manual rate. The calculator works out each item separately, rounds its amounts to two decimal places, and adds them to get the combined totals. Add SST or Remove SST applies to every item in the list.
How do I copy or print my calculation?
After entering valid values, choose Copy result to copy the amount breakdown, or Print result to open your browser's print dialog. In Multiple items mode, both include the individual items and combined totals. You can save a PDF if your browser offers that print option.
What is the difference between sales tax and service tax?
Service tax generally applies to prescribed taxable services provided by a taxable person in Malaysia. Sales tax is a single-stage tax on imported or locally manufactured goods, depending on the goods classification and current rules.
Can this SST calculator confirm whether my item is taxable?
No. The calculator only performs the arithmetic. Taxability depends on the service category, goods classification, exemptions, registration status, and current SST rules.
Can I use this result for SST filing?
Use the result as a checking estimate only. Before filing or issuing tax documents, confirm the SST category, rate, taxable period, and invoice treatment using official guidance or a qualified tax adviser.
