Roth IRA Growth (They are not investments by themselves. Your account can grow even in years when you can't contribute. You earn interest, which is added to your balance, and then you earn interest on interest, and so on. Stocks are a popular option for IRAs because the profits made are basically additional contributions to the IRA.
Stocks also increase IRAs through dividends and increases in share price. While no one can predict the future, the annual range of return on equity investments has historically been between 8 and 12%. A traditional IRA can be a great way to increase your savings by avoiding taxes while you build up your savings. You get a tax cut now when you make deductible contributions.
In the future, when you withdraw money from the IRA, you will pay taxes based on your ordinary income rate. That means you can end up with hundreds of thousands of dollars more by maximizing contributions to an IRA each year compared to putting the funds in a regular savings account. Non-spousal beneficiaries who have inherited an IRA, either a traditional or Roth IRA, after that date must now withdraw money from the account within a decade. If you don't qualify to deduct your IRA contributions, you can still accumulate money up to the annual limit in a traditional IRA.
Very few experts are very clear in telling you that you really need to invest your money when you have a Roth IRA, or even explain the differences between a traditional IRA and a Roth IRA.
