A Roth IRA can be a useful tool for accumulating the funds needed to pay for a comfortable lifestyle in retirement. That’s because it permits growth without owing taxes on investment gains, and also allows savers to withdraw funds in retirement without paying taxes on their withdrawals. Three things generate Roth IRA growth. Those are your contributions, earnings from interest and dividends on investments and increases in the value of assets purchased and held in the Roth IRA.
If you want to build out your retirement plan, a financial advisor can help you use a Roth IRA and other retirement accounts to boost your nest egg.
Roth IRA Basics
A Roth IRA is a retirement account you fund with after-tax dollars. Later on, you can take money from the account without owing taxes as long as you have had the account for at least five years and are past age 59.5.
There is an annual maximum on Roth IRA contributions. For 2025, the limit is $7,000 for retirement savers younger than 50. Roth IRAs are also subject to income limitations that mean higher-earning retirement savers can’t contribute to them at all. For 2025, the top income you can have if you want to contribute any money to a Roth IRA is less than $150,000 for individuals and less than $236,000 for married couples filing taxes jointly.
Roth IRAs are free of the traditional IRA’s mandate to take required minimum distributions (RMDs) once you reach 73 (75 in 2033). Without RMDs, Roth IRA owners are free to leave their money in to grow tax-free for a longer period of time.
How a Roth IRA Grows
Roth IRAs historically return an average of 7% to 10% per year. However, this return doesn’t come from the Roth IRA itself. These accounts are just tax-advantaged places to keep funds. The growth is generated by investments made with funds in the account. The rate of growth depends on where the funds are invested, as well as other factors including fees.
Growth in a Roth IRA comes from three sources: contributions, interest and dividends and price appreciation. Here is more on these three factors:
Contributions
Your contributions will drive the growth of your IRA in the early years. For example, if you open a Roth IRA at age 35 in 2023 with an initial $5,000 and contribute $6,500 annually while earning 7% returns, your total contributions by 2040 would be $116,500. In this 17-year period, your account could grow to approximately $234,566, with $118,066 coming from earnings—slightly more than your contributions.
Interest and Dividends
Over time, growth from interest and dividends plays a bigger role in building your Roth IRA’s value. Around 18 years in, earnings begin to outpace contributions, and this growth speeds up as more interest compounds.
By 2053, when you turn 65 and retire, your Roth IRA could grow to $652,056, with $452,056 coming from earnings. Less than a third of the total would come from your contributions.
Compound interest drives this growth. As earnings stay invested, they generate even more interest, allowing your savings to grow faster. Over time, compounding becomes the main factor increasing the value of your Roth IRA.
Appreciation
Price appreciation is another source of potential growth in your Roth IRA. Bank certificates of deposit, interest-earning bonds, dividend-paying stocks and other income-generating investments such as dividend funds are part of many Roth IRA portfolios. But other common Roth IRA investments, such as common stocks, do not pay dividends or interest.
Gains to your Roth IRA from these investments result from price appreciation or capital appreciation. You buy them at one price and sell them later for a higher price. Over long periods of time, such as a few decades, investments in stocks have historically outperformed investments in bonds and other income investments.
Price appreciation from stock investments represent an important part of the overall 7% to 10% average growth shown by Roth IRAs in the past. Because stock market valuations fluctuate less predictably than interest returns, they are more difficult to accurately predict, but they can still be expected to be important for your Roth IRA’s growth.

Bottom Line
Growth of a Roth IRA comes from three sources: contributions, interest and dividends and price appreciation of the assets held in the account. Of the three, contributions are most important early on, interest and dividends usually are more important later on, and price appreciation is historically the biggest factor in long-term growth, although this factor is harder to reliably quantify in advance.
