About This Tool
Goods and Services Tax (GST) is a unified destination-based consumption tax applied to sales of goods and commercial services. When creating client quotes, issuing commercial tax invoices, or reconciling purchase receipts, accountants and business operators need to switch between adding GST to a net base price (exclusive) or extracting embedded GST from a gross total price (inclusive).
This calculator supports both operational tax modes directly in your browser: - **Add GST (Tax Exclusive)**: Computes the tax surcharge added on top of a net base amount: $$ ext{GST Amount} = rac{ ext{Base Amount} imes ext{GST Rate}}{100}$$ $$ ext{Total Amount} = ext{Base Amount} + ext{GST Amount}$$ - **Remove GST (Tax Inclusive)**: Extracts the embedded tax component from a gross sales price: $$ ext{Base Amount} = rac{ ext{Gross Total}}{1 + ( ext{GST Rate} / 100)}$$ $$ ext{GST Amount} = ext{Gross Total} - ext{Base Amount}$$
### Distinct Worked Calculation Examples 1. **Adding 18% GST (Exclusive Mode)**: - Base Price: $5,000.00 - GST Rate: 18% - GST Amount: $(5,000 imes 18) / 100 = $900.00 - Total Invoiced Amount: $5,000 + $900 = $5,900.00
2. **Removing 18% GST (Inclusive Mode)**: - Gross Total: $5,000.00 - GST Rate: 18% - Extracted Base Price: $5,000 / (1 + 0.18) = $5,000 / 1.18 approx $4,237.29 - Extracted GST Component: $5,000 - $4,237.29 = $762.71
### How Your Data Is Processed Every calculation runs 100% client-side in your web browser using JavaScript arithmetic. Invoiced amounts, commercial tax rates, and accounting figures are calculated entirely on your local computer and are never transmitted to external servers or recorded in databases.

Frequently Asked Questions
What is the difference between GST inclusive and exclusive prices?
An exclusive price is the raw base cost before tax is added. An inclusive price is the final retail price that already contains the GST amount.
How does dual GST (CGST and SGST) split in intra-state transactions?
In domestic intra-state transactions, the total GST rate splits equally between Central GST (CGST) and State GST (SGST), each taking half the statutory percentage.
Are your accounting numbers or invoice amounts uploaded to any server?
No. All tax calculations execute strictly inside your local browser memory.
