GST Calculation Formula
GST Exclusive Formula (When price does not include GST)
Amount without GST × GST Rate / 100
Example:
Amount without GST = ₹1,00,000.00
GST Rate = 12%
GST Amount = (₹1,00,000.00 × 12) / 100 = ₹12,000.00
GST Inclusive Formula (When price already includes GST)
Amount with GST × GST Rate / (100 + GST Rate)
Example:
Amount with GST = ₹1,12,000.00
GST Rate = 12%
GST Amount = (₹1,12,000.00 × 12) / (100 + 12) = ₹12,000.00
GST Inclusive Calculator
A GST inclusive calculator helps you determine the base price and GST amount when the total price already includes GST. This situation is common when a product price is advertised with tax included, and you want to find the original value before GST. To calculate GST inclusive price, you simply enter the total amount and select the applicable GST rate such as 5%, 12%, 18%, or 28%. The calculator automatically removes GST from the total and shows the taxable value, GST amount, and final breakdown of CGST and SGST. This is useful for businesses, accountants, and e-commerce sellers who need to accurately determine the tax component included in a selling price.
GST Exclusive Calculator
A GST exclusive calculator is used when you want to add GST to a base price that does not include tax. Businesses often use this method while preparing invoices or estimating the final price of goods and services. Simply enter the original amount and select the applicable GST rate such as 5%, 12%, 18%, or 28%. The calculator will instantly compute the GST amount and the total price including tax. It also provides the CGST and SGST breakup, which is required for GST invoices in India. Using a GST exclusive calculator helps ensure accurate billing and avoids manual calculation errors while preparing invoices.
Reverse GST Calculator
A reverse GST calculator helps you remove GST from a total amount to find the original taxable value. This calculation is useful when the total price already includes GST and you want to determine the base amount before tax. For example, if the total price is ₹1180 with 18% GST, the calculator can determine that the taxable value is ₹1000 and GST is ₹180. By entering the total amount and selecting the GST rate, the tool quickly shows the GST amount, taxable value, and CGST and SGST breakup. This feature is particularly helpful for businesses, accountants, and sellers who need to verify GST included in invoices or product pricing.
