India VIX Calculator: Turn Volatility into an Expected NIFTY Range
Use this free India VIX calculator to turn the current India VIX into a clear expected move for the NIFTY. Enter the NIFTY spot price, the India VIX value and the number of days, and you will instantly see the expected percentage move, the approximate move in points and the expected price range.
That range is useful before you trade options, set a stop loss or judge whether a big move is already priced in. A higher VIX means a wider expected range, while a lower VIX points to a calmer market — but it never tells you the direction of the move.

What is a India VIX Calculator?
India VIX is an annualised implied-volatility index published by NSE. It is calculated from NIFTY option prices and shows the market’s expected volatility over the next 30 days, expressed as an annual percentage.
Expected move % = VIX x sqrt(days/365). Expected range = Spot ± (Spot x move% / 100). For example, a VIX of 14 means an expected move of about 4% over 30 days, because 14 x sqrt(30/365) is about 4.01%.
How to Use the India VIX Calculator (Step by Step)
1. Enter current NIFTY spot.
2. Enter current India VIX (published by NSE).
3. Enter period in days (30 = standard VIX horizon).
4. Press Calculate.
Example Calculation
Spot 25,000, VIX 14, 30 days gives an expected move of 4.01 percent (about 1,003.42 points), with an expected range of 23,996.58 to 26,003.42. This is an expected range, not a prediction that the market will reach either end.
Features
Expected percentage, points and price range together; any period you choose; standard square-root-of-time scaling; and a free, instant result with no sign-up.
Benefits
This calculator gives option-trading context, helps you set realistic move expectations, and makes event risk easier to judge around results or budget days, all without manual maths.
Final Thoughts
The India VIX calculator turns a single volatility number into a practical expected range for the NIFTY. Use it to plan trades, size positions sensibly and avoid overreacting to normal market movement. For related tools, try the TDEE Calculator and the Groww Average Calculator.
Frequently Asked Questions (FAQs)
What is India VIX?
India VIX is a volatility index computed by NSE from NIFTY option order book quotes. It shows the market’s expected volatility over the next 30 days, in annualised percent.
Does a high VIX mean the market will fall?
No. VIX measures expected movement size, not direction. High VIX means big moves are expected either way; it often spikes during falls because fear rises.
Why is the 30-day move smaller than the VIX number?
Volatility scales with the square root of time. A 14% annual figure becomes 14 x sqrt(30/365) = about 4% for 30 days.
Can I calculate India VIX myself from option prices?
The official VIX uses a full weighted formula over many option strikes and is published by NSE. This calculator uses a VIX value to find the expected move – it does not recompute the index.
