What Is A Stock Basis Calculator?

Good question and I’m glad you asked. A stock basis calculator helps the user determine a stock’s average price, also known as a stock cost basis.

 Some calculators vary in usage, but all tend to be somewhat similar in what they do. With this calculator, you can enter the amount of money invested/invested in the stock, the broker fees, and other trading expenses.

This also can be adjusted for corporate actions like mergers, stock splits, and dividend payments.

 As you can see, using a stock basis calculator brings many advantages and simplicity to the sometimes overwhelming and confusing procedure of calculating it all the traditional way.

What Happens If I Don’t Know My Cost Basis?

It’s advised that you search all your personal information and records and try to find the brokerage statements that will contain your actual cost basis.

If this fails, you can also try the brokerage firm’s website or contact them to see if they can provide you with the necessary information you require.

How Can I Calculate My Cost Basis If I Cannot Get The Needed Information From My Broker Or Statement?

I Have Sold Some Stock But Don’t Know The Original Purchase Price. How Could I Report The Cost Basis For The Transaction That’s Already Been Completed?

If a publicly-traded company issued the share, look up the historical rate for the shares online and report the share price at the same time as when you executed the purchase of the shares.

If a private company sold the share, contact the company to request the historical price of the stock in question. They should help you with what you need providing you can prove certain credentials.

If options 1 and 2 are not feasible (the share was issued by a company that has since changed ownership or name, or you can not find the historical rate), then report a cost basis of zero for sale.

If options 1 and 2 are not feasible and you are not willing to report a cost basis of zero, then you will pay a long-term capital gains tax of 10% to 20% depending on your tax bracket on the entire sale amount.

 Alternatively, you can estimate the initial price of the share. However, it would be best if you were prepared to explain to the IRS when asked how you calculated this price and so forth.

Do I Have A Cost Basis For A Stock I Received For Free?

The basis in the free stock is equal to the income you received when given the stock. You may need to adjust the cost basis as listed.

The cost basis of the stock you received as a gift or “gifted stock” is determined by the sender’s original cost basis and the stock’s fair market value at the time you received the gift.

If the full market value of when you received the gift was more the original cost, use the original cost basis when you sell. 

If the full market value of when you received the gift was less than the original basis, and you later sold the stock for:

  • More than the original cost.
  • More than the fair market value at the time of the gift but less than the original basis cost.

 Your selling price becomes the cost basis. You won’t report a gain or loss in this situation, Less than the total market value at the time of the gift.

When you enter the gift stock sale, select the appropriate situation when we ask if you bought the stock.
