Money Market Vs Mutual Fund

If a money market investment returns and a 2.35% expense ratio of 0.56% is it better to put money in the online savings account that returns 3.14 %? The answer is obvious. However, if the money market mutual fund is in a 401K. Suppose no consideration is involved to make the problem simpler. Put the money in the 401K to 2 tax benefits. It lowers your taxable income and the money earned by the Fund, the deferred taxes. Is that enough to overcome the decline in yield and the rate of expenditure?

Although it is not the case today, the average yield of the stock market over the last 100 years is about 10%, so it's a great time to buy mutual fund shares and not even think about any type of money market account

put your money in a money market or savings account once you are older and I hope to have accumulated a lot of money by investing

Depends on your tax bracket. But remember that with a 401 (k), you do not avoid the tax bite - just a reporter.
