Is my data safe when using Gst Calculator?

What is the difference between exclusive and inclusive GST?

Exclusive GST means the amount entered is before tax â€” GST is added on top. Inclusive GST means the amount entered already includes tax â€” GST is extracted to find the base price.

What is the difference between CGST+SGST and IGST?

CGST (Central GST) and SGST (State GST) apply to intra-state transactions (within the same state), split equally. IGST (Integrated GST) applies to inter-state transactions (across states), collected as a single tax.

What GST slabs are available in India?

India has six main GST slabs: 0% (essential goods), 3% (gold/diamond), 5% (basic necessities), 12% (standard goods), 18% (majority of goods/services), and 28% (luxury/demerit goods).

Can I use a custom GST rate?

Yes, click the Custom button and enter any rate. This is useful for special rates or non-Indian GST calculations.

How does the Invoice Itemizer work?

Add multiple items with different prices, quantities, and GST rates. The itemizer calculates the taxable value, total GST, and grand total for the entire invoice.
