You deposit $1,000 into a traditional brokerage account and invest in a stock you like. In five years, the stock is worth $3,000, so you sell. If you're in the 15% capital gains tax bracket, you'd owe $300 in federal income tax on the profit, leaving you $2,700 to reinvest. Now, let's say that investment triples in another five years, giving you an account value of $8,100. You'd owe another $810 in capital gains tax on this sale, giving you an ending value of $7,290.
Meanwhile, the same investments in an IRA would be worth more at the end. You would have been able to reinvest the full $3,000 in proceeds from the first, and the second would have grown to $9,000. And no capital gains tax would be due if you left the money in the account.
Obviously, this is a simplified example. You generally don't invest in just one stock, for instance. But the point is that investing in an IRA can help your retirement nest egg grow faster than it otherwise would be able to.
Benefits of an IRA vs. a 401(k)
There are also some big advantages to using an IRA as opposed to a 401(k).
- An IRA allows you to invest in virtually any stocks, bonds, mutual funds, or ETFs you want, as opposed to limiting you to a small menu of investments.
- An IRA has some early-withdrawal exceptions that don't apply to a 401(k), such as the ability to take money out to pay for college or to use toward a first-time home purchase.
