💡 GST Calculation Guide & Tips

🧮 How to Calculate GST

GST Exclusive (Add GST):

  • GST Amount = Base × (Rate ÷ 100)
  • Total = Base + GST Amount
  • Example: ₹1000 + 18% = ₹1000 + ₹180 = ₹1180

GST Inclusive (Remove GST):

  • Base = Total ÷ (1 + Rate ÷ 100)
  • GST Amount = Total - Base
  • Example: ₹1180 ÷ 1.18 = ₹1000 base, ₹180 GST

🏢 CGST vs SGST vs IGST

Intra-state Supply (Same State):

  • CGST = GST ÷ 2 (Central Government)
  • SGST = GST ÷ 2 (State Government)
  • Example: 18% GST = 9% CGST + 9% SGST

Inter-state Supply (Different States):

  • IGST = Full GST Rate (Central Government)
  • Example: 18% GST = 18% IGST

📊 GST Rate Categories

0% (Exempt): Essential items like rice, wheat, milk

5%: Basic necessities - sugar, tea, coffee, spices

12%: Processed foods, medicines, computers

18%: Most goods and services, electronics

28%: Luxury items, automobiles, tobacco

Special Rates: Some items have rates like 0.25%, 3%, 7.5%

💼 Business Tips

  • Rounding: Most businesses round to nearest rupee for invoicing
  • Input Tax Credit: Registered businesses can claim GST paid on purchases
  • Compliance: File GSTR returns on time to avoid penalties
  • Record Keeping: Maintain proper GST invoices and receipts

📝 Practical GST Examples

Example 1: Restaurant Bill

Scenario: Food bill of ₹500 + 5% GST

Calculation:

  • Base Amount: ₹500
  • GST (5%): ₹500 × 0.05 = ₹25
  • Total Bill: ₹500 + ₹25 = ₹525
  • CGST: ₹12.50, SGST: ₹12.50

Example 2: Electronics Purchase

Scenario: Laptop priced at ₹59,000 (GST inclusive)

Calculation:

  • Total Amount: ₹59,000
  • Base: ₹59,000 ÷ 1.18 = ₹50,000
  • GST (18%): ₹59,000 - ₹50,000 = ₹9,000
  • CGST: ₹4,500, SGST: ₹4,500

How this GST calculator works

Enter an amount and choose a GST rate (5%, 12%, 18%, 28% or custom). Select whether the amount is GST-inclusive or exclusive, and whether the supply is intra-state (CGST+SGST) or inter-state (IGST). For GST-inclusive, the base is back-calculated as amount � (1 + rate), and GST is the difference between total and base. For GST-exclusive, GST is base � rate and total = base + GST. When intra-state is chosen, GST splits equally into CGST and SGST; for inter-state, IGST applies.

Examples

Inclusive 18%: Amount ?1,180 inclusive . base = 1180/1.18 = ?1,000; GST = ?180 (CGST ?90 + SGST ?90, or IGST ?180).

Exclusive 12%: Base ?2,000 exclusive . GST = 2000 � 12% = ?240; total = ?2,240.

You can round to the nearest rupee for invoices or keep paise for precise calculations. Share a link or export CSV for records.

FAQs

CGST/SGST vs IGST?

Intra-state supplies split GST into equal CGST and SGST components. Inter-state supplies levy IGST. This is a display split and doesn�t change the total.

Which rates are common?

Many essentials are 0% or 5%; services and goods often fall under 12% or 18%; luxury items may be 28%. Always verify the applicable rate for your item/service.

Is this a filing tool?

No. It�s a quick calculator to estimate base/GST/total for quotes and invoices; it does not file returns.
