Where to find implied volatility on your broker

The one option input you cannot read off the stock price

Implied volatility (IV) is the market's estimate of how much a stock will move, quoted as an annualized percentage. It drives an option's price, and unlike the strike or the stock price you cannot just look it up on a ticker: you read it from your broker's option chain. These short guides show exactly where each broker puts it.

Robinhood

Robinhood does not show implied volatility on the main option chain grid. You have to open a specific contract to see it. Here is exactly where to tap.

  1. Open the stock or ETF you want in the Robinhood app and tap Trade, then Trade Options.
  2. Pick an expiration date at the top, then choose Call or Put.
  3. Tap the specific strike you are interested in to open that contract’s detail screen.
  4. Scroll to the contract’s stats. Implied Volatility is listed there alongside the Greeks (delta, gamma, theta, vega).
  5. Read the percentage. That is the number to type into a calculator as your IV input.

Schwab and thinkorswim

Schwab and its thinkorswim platform both show implied volatility per contract once you add the column. On thinkorswim you can also chart it as a study.

  1. Open the option chain for your ticker (Trade tab on thinkorswim, or Research then Options on Schwab.com).
  2. Open the column layout menu. On thinkorswim, click the small gear or right-click a column header and choose Customize.
  3. Add the Impl Vol column (sometimes shown as “IV”) to the layout and apply.
  4. Read implied volatility per strike directly in the chain. Each contract now shows its own IV.
  5. Optional on thinkorswim: add the ImpVolatility study to a chart to see IV over time for the whole symbol.

Fidelity

Fidelity shows implied volatility on the option chain once you switch the column on in the chain's settings. It takes about thirty seconds.

  1. From Fidelity.com or the app, search your ticker and open Research, then the Options chain.
  2. Find the chain's column settings (a gear icon or a “Customize columns” link above the table).
  3. Enable the Implied Volatility column and save the layout.
  4. Read implied volatility next to each strike and expiration in the chain.
  5. Use the IV of the specific contract you are considering, not an average, when you price it.

Interactive Brokers (IBKR)

Interactive Brokers (IBKR) shows implied volatility once you add the column in the Option Chain or OptionTrader. It is also on each contract's info panel.

  1. Open the Option Chain or OptionTrader for your symbol in Trader Workstation or the IBKR app.
  2. Right-click a column header (or use the columns menu) and choose to insert a column.
  3. Add Implied Vol % from the list of available option fields and apply.
  4. Read implied volatility per contract in the chain.
  5. Alternatively, right-click a contract and open Financial Instrument Info, where the implied volatility is also shown.

Webull

Webull shows implied volatility on each contract's detail panel, and it can also display an IV column on the chain. Here is where to look.

  1. Open the ticker in Webull and go to its Options tab to bring up the chain.
  2. Choose an expiration date, then tap the specific contract (strike) you want.
  3. On the contract's detail panel, read the IV field shown with the Greeks.
  4. To compare across strikes, open the chain's column or display settings and enable an IV column if you prefer it on the grid.
  5. Use that contract's IV percentage as your input when you price the option.
Broker apps get redesigned often, so a menu name here may not match yours exactly. If a step looks different, search your broker’s own help for “implied volatility column” or “IV” and you will usually find it in a minute.

Frequently asked questions

What is implied volatility, and why do I need it?

Implied volatility, or IV, is the market's estimate of how much a stock will move, quoted as an annualized percentage. Every option pricing model needs it, and it is the one input you cannot read off the stock price. You take it from your broker's option chain, then feed it into a calculator.

My broker isn't listed here. Where do I look?

The idea is the same everywhere: open the option chain, then find or enable an implied volatility column, or open a single contract's detail view. If it is not obvious, search your broker's help for “implied volatility column” or “IV.”
