✅ Why Use a GST Calculator?
Every item or service you purchase includes GST. Being aware of the exact tax amount you’re paying helps you make informed decisions.
Here’s how a GST calculator can help you:
🧮 Instant GST estimation based on your inputs
⏱️ Saves time by automating calculations
🛡️ Protects against overcharging or miscalculated tax
📊 Transparency in every transaction
💡 GST Calculation Methods
A GST calculator helps you with both inclusive and exclusive tax computations using standardized formulas:
1. When GST is Exclusive (Tax to be Added)
Formula:
GST Amount = (Original Price × GST%)
Total Price = Original Price + GST Amount
Example:
For a product priced at ₹100 with 18% GST:
GST = 100 × 0.18 = ₹18
Total = ₹100 + ₹18 = ₹118
2. When GST is Inclusive (Tax Included in Price)
Formula:
GST Amount = Price – [Price × 100 / (100 + GST%)]
Base Price = Price – GST Amount
Example:
If a product costs ₹118 inclusive of 18% GST:
Base Price = 118 × 100 / 118 = ₹100
GST = ₹18
🌐 How to Use an Online GST Calculator
Using a GST calculator is simple and quick:
Enter the amount and choose the GST rate.
Select whether the value is inclusive or exclusive of GST.
The calculator instantly displays the tax amount and the total or base value.
🔍 GST Inclusive vs. Exclusive Amounts
GST Inclusive
The price already includes the GST. The customer doesn’t pay anything additional for tax—it’s part of the final price shown.
GST Exclusive
The GST is added separately on top of the product’s base price. The final amount is higher than the listed base price.
