Complete Guide to GST Calculations (FY 2026-27)
GST (Goods and Services Tax) calculation business management ka ek core hissa hai. Tederr Tools ka ye **Smart GST Engine** specially design kiya gaya hai un entrepreneurs ke liye jo accuracy aur speed dono chahte hain. Is tool mein humne latest Finance Act 2026 ke rules ko integrate kiya hai.
Protocol Architecture
01. Mode Selection
Aap **GST Excluded** (Price + Tax) ya **GST Included** (Tax hidden in price) choose kar sakte hain. Engine automatically back-calculation perform karta hai.
02. Slab Selection
India mein 4 primary slabs hain (5%, 12%, 18%, 28%). Engine har slab ke liye CGST aur SGST ko 50:50 ratio mein distribute karta hai.
GST Tax Slabs & Categories 2026
| Tax Slab | Usage Type | CGST / SGST |
|---|---|---|
| 5% GST | Essential Items (Sugar, Oil, Tea) | 2.5% Each |
| 12% GST | Standard Items (Butter, Cheese) | 6% Each |
| 18% GST | Services & Most Goods (Default) | 9% Each |
| 28% GST | Luxury Items (Cars, Tobacco) | 14% Each |
Rounding Off & Precision
Ek common issue jo billing mein aata hai wo hai decimal points. Tederr Engine **Mathematical Rounding (to the nearest whole number)** ka use karta hai. Agar aapka total ₹100.49 aata hai, toh engine ise ₹100 rakhega, aur ₹100.50 ko ₹101 kar dega. Isse manual ledger maintain karne mein aasani hoti hai.
Humne isme **Number-to-Words** conversion bhi add kiya hai taaki cheque writing ya formal invoice generation mein galti ki gunjayish na rahe. Ye feature hamare engine ko baaki simple calculators se alag banata hai.
Frequently Asked Questions
GST Inclusive vs Exclusive mein kya farq hai?
Exclusive ka matlab hai ki tax base price ke upar add hoga. Inclusive ka matlab hai ki total price mein tax pehle se shamil hai, aur hum base value nikal rahe hain.
Kya ye data kahin save hota hai?
Nahi. Tederr Engine client-side calculation par chalta hai. Aapka financial data aapke browser tak hi mahdood hai.
