Fees are one of the biggest killers of portfolio performance.  Over 30 years, the difference between a 2% cost and a 0.04% fee might result in your portfolio losing half its value.

FXAIX has a 0.015% expense ratio, whereas VTSAX has a 0.04% expense ratio.

In this case, both of these funds have a similar cost.

The Vanguard Total Stock Market Index Fund Admiral (VTSAX) is less expensive than 96% of rival funds.

Which Is Better FXAIX or VTSAX?

FXAIX and VTSAX are similar in performance.  In addition, FXAIX offers exposure to the S&P 500 at a lower expense ratio of 0.015%.  However, if you are not a Fidelity investor, you must pay commissions to buy FXAIX.

VTSAX, on the other hand, can be purchased commission-free by purchasing its equivalent ETF (VTI) with Vanguard or M1 Finance. ***(Get $100 When You Use This Link)***

It is important investors buy FXAIX or VTSAX commission-free.  Fees can take away from your portfolio returns and compound over time.

I expect FXAIX and VTSAX to perform similarly over the next 10 years.  The expense ratio isn't a significant difference.


Is FXAIX a Good Fund?

If you are seeking exposure to the S&P 500, FXAIX is a good fund option consistent with low fees.

A good investment aims to replicate the target index returns at the lowest cost possible.

Therefore, investors should seek the lowest-cost fund that meets their investment goals.

My Winner: VTSAX

VTSAX and FXAIX are similar in dividend yield and annual returns.  They also offer low fees.

Yet, VTSAX is a Vanguard fund, while FXAIX is a Fidelity fund.  Vanguard's ownership structure provides an incentive to continue to offer low-cost options.

Fidelity is not guaranteed to keep their prices low.  As a result, they could increase the expense ratio of FXAIX in the future.

This shouldn't discourage you from considering FXAIX, especially if you buy the fund through Fidelity.

The decision might come down to which brokerage you prefer.

If you already have an account at Vanguard, VTSAX might fit you best.

FXAIX is an excellent option to consider if you are with Fidelity.
