GST Calculation Formula

Two scenarios — adding GST to a base price, or removing GST from a price that already includes it.

➕ Add GST to Price (Exclusive GST):
GST Amount = Price × GST Rate ÷ 100 Total Price = Price + GST Amount

Example: ₹1,000 at 18% → GST = ₹180 → Total = ₹1,180

➖ Remove GST from Price (Inclusive GST):
Base Price = Total ÷ (1 + GST Rate ÷ 100) GST Amount = Total Price − Base Price

Example: ₹1,180 at 18% → Base Price = ₹1,000 → GST = ₹180

CGST vs SGST vs IGST — Kya Difference Hai?

Whether CGST+SGST or IGST applies depends on where your buyer is. Accountune detects this automatically on every invoice.

CGST
Central GST — Same State Sale Half of total GST. Goes to Central Govt. Delhi → Delhi at 18% → CGST 9%
SGST
State GST — Same State Sale Half of total GST. Goes to State Govt. Delhi → Delhi at 18% → SGST 9%
IGST
Integrated GST — Interstate Sale Full GST rate. Goes to Central Govt. Delhi → Mumbai at 18% → IGST 18%

Frequently Asked Questions — GST Calculator India

20 most common questions about GST calculation, rates, and compliance in India 2026

GST calculator kaise use karein?
Mode select karo — "Add GST to Price" ya "Remove GST from Price". Amount enter karo. GST rate select karo (0%, 5%, 12%, 18%, 28%). Calculator automatically GST amount, CGST, SGST aur IGST breakdown show karega.
18% GST ka matlab kya hai? Example ke saath batao.
₹1,000 ke product pe 18% GST = ₹180 tax. Total amount = ₹1,180. Agar intra-state sale hai toh CGST ₹90 + SGST ₹90. Agar interstate sale hai toh IGST ₹180 lagega.
GST inclusive aur exclusive mein kya fark hai?
Exclusive GST = price mein GST shaamil nahi hai, baad mein add karna hoga. Inclusive GST = price mein GST pehle se shaamil hai, sirf nikalna hoga. MRP India mein hamesha inclusive hoti hai.
Kya MRP mein GST included hota hai?
Haan. India mein packaged goods ki MRP (Maximum Retail Price) mein GST already included hoti hai. Jo price tag pe likha hai woh final consumer price hai — usmein GST already add hai.
CGST aur SGST hamesha equal hote hain kya?
Haan — hamesha. Intra-state (same state) sale mein CGST aur SGST dono total GST ke exactly aadhe aadhe hote hain. 18% GST = CGST 9% + SGST 9%. 12% GST = CGST 6% + SGST 6%.
Interstate aur intrastate sale mein GST ka kya fark hai?
Intrastate (same state) = CGST + SGST lagta hai dono equal parts mein. Interstate (alag state) = sirf IGST lagta hai full rate pe. Total GST amount dono cases mein same hota hai — bas division alag hoti hai.
Footwear pe GST rate kya hai India mein?
Footwear ke liye GST slab selling price pe depend karta hai. ₹1,000 ya usse kam pe 5% GST. ₹1,000 se zyada pe 12% GST. Agar sale ke time discount di aur price ₹1,000 se neeche aa gaya toh GST rate 5% ho jaata hai automatically.
Medicine aur pharma products pe GST rate kya hai?
Most medicines (drugs listed in essential medicines list) pe 5% GST lagta hai. Ayurvedic medicines pe bhi generally 5% hai. Medical devices aur equipment pe 12% ya 18% ho sakta hai depending on product type. HSN code se exact rate verify karo.
GST ke liye HSN code kya hota hai aur kyun zaroori hai?
HSN (Harmonized System of Nomenclature) code ek 4-8 digit ka product classification code hai. Har product ka apna HSN code hota hai jo uski GST rate determine karta hai. GST invoice mein HSN code mandatory hai. Wrong HSN code lagane pe penalty ho sakti hai.
GST calculate karne ka sabse aasaan tarika kya hai?
Iss calculator se — amount enter karo, rate select karo, result milega. Lekin daily business ke liye Accountune jaisa billing software use karo jahan GST automatically calculate hota hai har invoice pe — no manual calculation needed. ₹799/year mein.
Kya GST exempt goods pe invoice banana padta hai?
Haan. 0% GST wale goods pe "Bill of Supply" banana padta hai — Tax Invoice nahi. Bill of Supply mein GST amount nahi hota but GSTIN, HSN code aur other details required hoti hain. Accountune automatically correct document type select karta hai.
What is Input Tax Credit (ITC) in GST?
Input Tax Credit woh GST hai jo aapne purchases pe pay kiya — aap use apni sales pe collected GST se minus kar sakte ho. Net GST payable = GST collected on sales minus GST paid on purchases. ITC claim karne ke liye supplier ka GSTR-1 filed hona zaroori hai.
GST registration kab zaroori hota hai?
Annual turnover ₹40 lakh (goods) ya ₹20 lakh (services) se zyada hone pe GST registration mandatory hai. Special category states mein limit ₹10-20 lakh hai. Interstate supply, e-commerce sales ya certain notified services pe turnover limit ke bina bhi registration zaroori hai.
GSTR-1 aur GSTR-3B mein kya fark hai?
GSTR-1 = outward supplies ka detail return, har invoice wise. 11th of next month tak file karna hota hai. GSTR-3B = summary return jismein total sales, purchases, ITC aur net tax payable hota hai. 20th of next month tak file karna hota hai. Accountune dono auto-generate karta hai billing data se.
GST late filing penalty kitni hoti hai?
Late filing fee ₹50 per day (CGST ₹25 + SGST ₹25) hoti hai — maximum ₹5,000 per return. Iske upar unpaid tax pe 18% per annum interest bhi lagta hai from due date. Nil return late filing pe ₹20 per day (maximum ₹500) lagta hai.
Composition scheme kya hai aur kiske liye sahi hai?
Composition scheme small businesses ke liye ek simplified GST scheme hai. Annual turnover ₹1.5 crore tak wale goods traders aur ₹50 lakh tak wale service providers opt kar sakte hain. Fixed rate pe tax pay karo (1-6%), quarterly return file karo. ITC nahi milta. Simple compliance chahiye walon ke liye sahi hai.
E-invoicing kya hai aur kiske liye mandatory hai?
E-invoicing matlab government ke Invoice Registration Portal (IRP) se IRN (Invoice Reference Number) generate karna. Annual turnover ₹5 crore se zyada wale businesses ke liye mandatory hai. Accountune Growth aur Pro plans mein e-invoicing built-in hai — invoice create karo, IRN automatically generate hota hai.
GST invoice mein kya kya hona zaroori hai?
Mandatory fields: Supplier aur buyer GSTIN, invoice number, date, HSN/SAC code, taxable value, GST rate, CGST/SGST/IGST amount separately, total amount, place of supply. B2C invoice mein buyer GSTIN optional hai. Accountune automatically sab fields fill karta hai.
GST invoice automatically kaise banayein bina manual calculation ke?
