🧾 GST Slab Selector – Formula & Working Method

GST (Goods and Services Tax) India ka ek indirect tax system hai jo goods aur services par lagta hai.

📊 GST Slabs in India

  • 0%

  • 5%

  • 12%

  • 18%

  • 28%

🔢 GST Calculation Formula

GST Amount = (Amount × GST Rate) / 100

Total Amount = Amount + GST Amount

✅ GST Calculation Example

Agar product price ₹5,000 hai aur GST slab 18% hai:

  • GST = (5,000 × 18) / 100 = ₹900

  • Total Amount = 5,000 + 900 = ₹5,900

🛠 GST Slab Selector Use Karne Ka Tarika

  1. Amount enter karein

  2. GST slab select karein

  3. Calculate button dabayein

  4. GST aur total payable amount turant milega

👉 Ye calculator business owners, shopkeepers, freelancers ke liye kaafi useful hai.

💰 Income Tax Calculator (Basic) – Formula & Slab Logic

Income Tax aapki annual income par depend karta hai aur slab system par kaam karta hai.

📊 Basic Income Tax Slabs (Example)

Income Range Tax Rate
₹0 – ₹2.5 lakh 0%
₹2.5 – ₹5 lakh 5%
₹5 – ₹10 lakh 20%
Above ₹10 lakh 30%

🔢 Income Tax Formula

Total Tax = Slab Wise Tax – Deductions

✅ Income Tax Example

Annual Income = ₹7,00,000

  • ₹2.5L → No tax

  • ₹2.5L (5%) → ₹12,500

  • ₹2L (20%) → ₹40,000

Total Tax = ₹52,500

🎂 Age Calculator – Date Difference Formula Explained

Age Calculator aapki Date of Birth se current date tak ka exact difference nikalta hai.

🔢 Age Calculation Formula

Age = Current Date – Date of Birth

Is calculation me:

  • Years

  • Months

  • Days

automatically calculate hote hain.

✅ Age Calculator Example

  1. DOB select karein (mm/dd/yyyy)

  2. Calculate button click karein

  3. Exact age turant milegi

👉 Useful for school forms, exams, insurance, government documents.

🔬 Physics Calculator – Motion & Electricity Formulas

Physics ke formulas students ke liye kaafi confusing hote hain. Calculator inhe easy bana deta hai.

🚀 Motion (Speed & Velocity) Formulas

1️⃣ Speed Formula

Speed = Distance / Time

Example:
Distance = 120 m
Time = 30 sec
Speed = 4 m/s

2️⃣ First Equation of Motion

v = u + at

3️⃣ Second Equation of Motion

s = ut + ½at²

4️⃣ Third Equation of Motion

v² = u² + 2as

⚡ Electricity Formulas

1️⃣ Ohm’s Law

V = I × R

2️⃣ Electric Power

P = V × I

3️⃣ Electric Energy

Energy = Power × Time

🛠 Physics Calculator Use Kaise Kare

  1. Distance, time, voltage ya current enter karein

  2. Calculate button press karein

  3. Result instantly milega

👉 Helpful for Class 9–12, JEE, NEET & competitive exams.
