Anvilon: Option Vest Calculator

Fill out one row for each option grant. Select [Add Grant] to add new rows.
grant options	Number of shares granted.
strike price	Exercise price per share. This is the cost to you.
vest start	Vesting commencement date; the date when vesting began in the format YYYY/MM/DD.
vest months	Number of months over which the options vest starting from the "vest began" month (4 years is 48 months). Append "/3" if vesting occurs every 3 months.
cliff months	If the grant has a one year cliff (25% of four years), then enter 12.
options exercised	Number of shares in the grant which have been exercised (purchased).

The following two fields apply to the entire calculation:
stock price	Current (or speculative) selling price of the stock. Enter a ticker symbol for a delayed quote lookup.
as of date	The "current" month or date for the calculations; in the format YYYY/MM (or use YYYY/MM/DD to break out individual grant vesting days in the results).

This software may have bugs or errors in it. You should verify all calculations by hand or using other tools before making major decisions. There are quite a few rounding operations which take place, possibly affecting the accuracy of final numbers.

Some of the displayed numbers may not show all significant digits, especially in the case of monthly value, cost, and earnings.

Trading costs and tax considerations are not taken into account. For more information, please talk to a qualified accountant, lawyer, and broker. Especially for tax considerations as there are many and they are not simple.

Some of your option grants may vest at different times during the month. This program groups all of these together, so you may have to wait until the middle or end of a month to be able to excercise them.

This program does not account for stock you have sold.
