How Goods and Services Tax (GST) Calculations Work
GST is a multi-stage tax imposed on the sale of goods and services. Calculations depend on whether the baseline cost already includes or excludes the tax amount.
Formula: Add GST (Exclusive)
GST Amount = (Base × Rate) ÷ 100
Total Value = Base + GST Amount
Formula: Remove GST (Inclusive)
Base Value = Total ÷ (1 + (Rate ÷ 100))
GST Amount = Total – Base Value
For domestic trade (such as inside India or Pakistan), GST splits equally into Central Goods and Services Tax (CGST) and State Goods and Services Tax (SGST).
