1. What is Goods and Services Tax (GST)?
GST is a comprehensive destination-based indirect tax levied on the manufacturing, sale, and consumption of goods and services across India. As highlighted in digital business standards on Google Search Central, offering transparent financial calculators simplifies compliance workflows for consumers and commercial enterprises alike.
2. Inclusive vs. Exclusive GST Calculation Formulas
Our algorithmic GST Calculator applies official mathematical taxation models:
- GST Exclusive (Add GST): $\text{GST Amount} = \frac{\text{Net Price} \times \text{GST Rate}}{100}$ | $\text{Gross Price} = \text{Net Price} + \text{GST Amount}$
- GST Inclusive (Remove GST): $\text{Net Price} = \frac{\text{Gross Price}}{1 + (\text{GST Rate} / 100)}$ | $\text{GST Amount} = \text{Gross Price} – \text{Net Price}$
3. Understanding CGST, SGST, and IGST Splits
For intra-state transactions (sales within the same state), the total GST evaluated by the GST Calculator is divided equally into Central GST (CGST) and State GST (SGST). For inter-state sales, Integrated GST (IGST) is applied directly to the central government account.
4. Frequently Asked Questions (FAQs)
