How It Works & Screenshots

Select call or put. Enter strike, underlying price and option price. You may also enter dividend yield and interest rate.

You can set time to expiration either as current and expiration date, or as number of days left to expiration. Intraday is fine – the calculator can work with fractions of days.

Click the big button and see implied volatility immediately. It is shown annualized, as well as per month, per week, per day and for the time period left to expiration. You can also see the Greeks for the given option price and IV.

With the chart you can model the effects of volatility changes on option price or individual Greeks.

The example below shows the effect of volatility changes on a (slightly-in-the-money) call option’s delta.

Volatility is the most important factor driving option prices and thereby option trading success. This calculator helps you better understand volatility and work with it effectively when making decisions.

Frequently Asked Questions

Is it a one-time payment or monthly/recurring?
One-time payment, yours forever.

Does it work in my version of Excel?
The calculator works in all versions of Excel from Excel 97 to Excel 2016. It was developed in Excel 2010 and tested in other versions. For older versions you may need to use a different version of the calculator, which is also included.

Does it work in OpenOffice / LibreOffice / Apple Numbers / other spreadsheet software?
It may work in some, but unfortunately we can’t guarantee it and can’t provide support for software other than Microsoft Excel. Generally you need your software to support Excel formulas and macros.

How do I pay? Is it secure?
You can pay by credit/debit card or PayPal. All payments are processed by PayPal, which provides world-class security and buyer protection. You don’t need a PayPal account to check out when paying with a card.
