Calculate GST amount and final price
What Is a GST Calculator
A GST Calculator helps you quickly calculate the tax amount and final price.
Depending on the calculator, you may be able to calculate:
- GST amount
- Price including GST
- Price excluding GST
- Original price before GST
- Total price after tax
You can enter the amount and GST percentage to get the result instantly.
GST Formula
When GST is added to a price, the basic formula is:
The final price is:
For example, if the original price is โน1,000 and GST is 18%:
โน1,000 ร 18 รท 100 = โน180
Final price:
โน1,000 + โน180 = โน1,180
GST Calculator Example
Suppose a product costs โน5,000 before GST and the GST rate is 18%.
GST amount:
โน5,000 ร 18 รท 100 = โน900
Final price:
โน5,000 + โน900 = โน5,900
So, the GST amount is โน900 and the final price is โน5,900.

GST Inclusive Price
A GST-inclusive price already contains the tax.
For example, if a product is listed at โน1,180 including 18% GST, the price before GST is lower than โน1,180.
To find the original price from a GST-inclusive amount, the calculation is different from simply subtracting 18%.
The basic formula is:
For example:
โน1,180 ร 100 รท 118 = โน1,000
GST amount:
โน1,180 โ โน1,000 = โน180
GST Exclusive Price
A GST-exclusive price does not include GST.
For example, if the price is โน1,000 before 18% GST, the GST amount is โน180 and the final price becomes โน1,180.
This distinction is important when comparing product prices or invoices.
GST Calculator for Businesses

GST Calculator for Shopping
Customers can use a GST calculator to understand how much tax may be added to a listed price.
For example, if a product costs โน2,500 before 18% GST:
GST:
โน2,500 ร 18 รท 100 = โน450
Final price:
โน2,500 + โน450 = โน2,950
This makes it easier to understand the actual cost.
