01 / GST MODE

Calculate GST your way

Exclusive adds GST to discounted taxable value; inclusive extracts GST from the discounted price.

02 / SETTINGS & ITEMS

Search the named systems, or choose Custom / Other Country. Comparable systems are labeled separately from GST; this is a generic estimate, not country-specific tax advice.

Country suggests a display currency only. Enter your rate or choose an example preset; rates are never inferred from the country. Select India’s transaction type yourself.

Example rates:

Discounts apply to the full line after quantity and before GST. Rates can differ per item. Currency changes display and decimal precision, never exchange rates.

Choose a transaction type if needed, then enter a price to see an instant GST estimate.

GST estimates use per-line currency rounding. For India intra-state, any odd minor unit goes to CGST and the remainder to SGST/UTGST. Local rules, exemptions and rounding can vary; verify your transaction. No live rates, tax filing or uploads.

Frequently asked questions

How does inclusive GST differ from exclusive GST?

Exclusive adds GST to the discounted taxable amount. Inclusive extracts the tax already included in the discounted total by dividing by 1 plus the GST rate.

How does the India CGST and SGST/UTGST breakdown work?

Choose intra-state yourself. The calculator divides each rounded line's GST into CGST and SGST/UTGST, assigning an odd minor currency unit to CGST so the parts add up.

When does it show IGST?

Choose inter-state for an India transaction. The rounded GST amount is shown as IGST. The tool does not determine your tax jurisdiction.

Are the GST preset rates current for the selected country?

No. They are editable examples, not live tax rates or tax advice. Check the rate and exemptions that apply to your transaction.

Can different items have different rates or discounts?

Yes. Multi-item mode accepts a quantity, price, rate and optional percentage or fixed discount per line, then sums the rounded line results.

How are discounts, currency and rounding handled?

Discounts apply to the line after quantity and before GST extraction or addition. Values are rounded per line to the display currency's minor unit; no exchange-rate conversions occur.
