Where to find your purchase price on Vanguard's website

Your purchase price appears in your account under the Holdings or Positions section, listed as Cost Basis or Average Cost. Log into your Vanguard account, select the account holding the ETF, and look for a column labeled "Cost Basis Per Share" or similar. This is the average price you paid per share across all your purchases of that ETF.

If you bought the ETF in multiple transactions, Vanguard calculates the average cost across all those purchases. For example, if you bought 10 shares at $50 and 10 shares at $60, your average cost basis would show as $55 per share. This average is what Vanguard uses to calculate your gain or loss when you sell.

The cost basis information is available on both the web platform and the Vanguard mobile app. On the web, it typically appears in a table format when you click into a specific holding. On the mobile app, you may need to tap into the individual position to see the detailed cost information.

Key Takeaways

  • Cost basis is shown in your Holdings section as either "Cost Basis Per Share" or "Average Cost," representing the average price you paid for each share.
  • If you made multiple purchases of the same ETF, Vanguard automatically calculates the weighted average across all transactions.
  • You can view cost basis on both the Vanguard website and mobile app by navigating to your account positions.
  • Your cost basis is used to calculate capital gains or losses when you sell the ETF, which matters for tax reporting.

How Vanguard calculates cost basis for multiple purchases

When you buy an ETF more than once, Vanguard uses the average cost method by default. This means it adds up the total amount you spent on all shares and divides by the total number of shares you own. The result is your average cost per share, which appears in your account.

This method is straightforward and is what most investors use. It differs from other cost-tracking methods like FIFO (first in, first out) or specific identification, which some investors use for tax purposes. Vanguard allows you to change your cost basis method if you want to use a different approach, but average cost is the standard starting point.

The cost basis updates each time you make a new purchase. If you buy more shares at a higher price, your average cost per share will increase. If you buy at a lower price, it will decrease. Vanguard recalculates this automatically.

Viewing cost basis in your account statements

Your cost basis also appears on your account statements, which Vanguard sends monthly or quarterly depending on your account activity. The statement shows the cost basis per share for each holding as of the statement date. This gives you a record you can keep for your files.

If you need historical cost basis information from a specific date in the past, you can download older statements from your account. Vanguard typically keeps statements available for several years in your online account history. This is useful if you sold an ETF and need to verify the cost basis you used for tax reporting.

Why cost basis matters for taxes

Your cost basis determines how much capital gain or loss you have when you sell. If you sell an ETF for $75 per share and your cost basis was $50 per share, you have a $25 per share gain. This gain is taxable in a regular brokerage account (though not in retirement accounts like IRAs or 401(k)s).

Keeping accurate records of your cost basis is important for tax time. When you file your taxes, you will report the sale price, the cost basis, and the resulting gain or loss. The IRS matches this information against what your broker reports on Form 1099-B, so the numbers need to match. Vanguard provides this information to the IRS automatically, so using the cost basis shown in your account is the safest approach.

What to do if cost basis is missing or incorrect

Cost basis information should always be present for ETFs you bought through Vanguard after 2011, when brokers began tracking this information. If you transferred an ETF to Vanguard from another broker, the cost basis may not transfer with it, or it may show as unknown. In that case, you will need to contact Vanguard to provide the historical purchase information if you have it.

If you believe your cost basis is incorrect, contact Vanguard's customer service with documentation of your original purchases. They can review your account history and correct it if there was an error. Keep records of your purchase confirmations so you can provide proof if needed.

Checking cost basis before you sell

Before you sell any ETF shares, take a moment to review your cost basis in your account. This helps you understand whether you will have a gain or loss, which can affect your tax situation for the year. If you are selling at a loss, you may want to hold off if you plan to buy the same or a substantially identical ETF soon, because the wash-sale rule could prevent you from deducting that loss.

Knowing your cost basis also helps you make informed decisions about which shares to sell if you own the same ETF in multiple accounts or bought it at different times. Some investors deliberately sell shares with higher cost basis to minimize their tax bill, though this requires specific identification rather than the default average cost method.

Frequently Asked Questions

Can I change my cost basis method after I buy an ETF?

Yes, you can change from average cost to specific identification or FIFO, but only before you sell. Once you sell shares, the cost basis method for that sale is locked in. Contact Vanguard if you want to change your method for future sales. This is mainly useful for tax planning if you have bought the same ETF at very different prices.

Does cost basis include dividends I reinvested?

Yes. When you reinvest dividends to buy more shares, those new shares are added to your cost basis calculation. The price you paid for those dividend-purchased shares becomes part of your average cost. This is automatic and requires no action on your part.

What if I inherited an ETF from someone else?

Inherited securities receive a "stepped-up" cost basis, meaning your cost basis is the value of the ETF on the date of death, not what the previous owner paid. Vanguard should reflect this automatically, but verify it in your account or contact them to confirm the stepped-up basis was applied correctly.

Is cost basis the same as my purchase price?

Cost basis is your average purchase price per share if you bought multiple times. If you bought only once, they are the same. Cost basis includes any fees or commissions Vanguard charged at purchase, though most ETF purchases at Vanguard have no commission.
