A Roth IRA is a widely used retirement savings account with key tax advantages. Unlike traditional IRAs, which may offer tax deductions upfront, Roth IRAs are funded with after-tax dollars, which means tax-free withdrawals in retirement. The calculator below can help you estimate your maximum annual Roth IRA contribution, as well as your balance at retirement.

About this Roth IRA calculator
How to fill out your Roth IRA details
Contribution year: Every year, the IRS reviews IRA contribution limits and Roth IRA income limits, which can affect whether or not and how much you can contribute to your Roth IRA. Most people will now be contributing for 2026. However, you can make 2025 contributions until Oct. 15, 2026 if you filed an extension — toggle to 2025 in the calculator to use this option.
Current age: The age you are now. Those 50 or older are eligible to contribute an extra $1,100 as a catch-up contribution in 2026.
Tax filing status: This is the filing status that you report to the IRS on your tax forms. Filing status is one of two factors considered when determining your Roth IRA contribution limit.
Annual income: For the purposes of this calculator, use your modified adjusted gross income (MAGI), which is your adjusted gross income with specific deductions added back in. It’s one of two factors used to determine your Roth IRA contribution limit (the other being filing status).
Starting balance: The total current balance in your Roth IRA.
Annual contribution: The amount that you plan to contribute to your Roth IRA each year. The maximum amount you can contribute to your Roth IRA depends on your age, your filing status and modified adjusted gross income.
Estimated rate of return: The annual rate of return is the amount the investments in your Roth IRA lose or gain in a year. The Roth IRA calculator defaults to a 6% rate of return, which can be adjusted to reflect the expected annual return of your investments.
Retirement age: Your retirement age is the age you hope to retire. The full retirement age ranges from 65 to 67, depending on your year of birth.

Roth IRA contribution and phase-out limits
The amount you can contribute to a Roth IRA depends on your annual income. The Roth IRA contribution limit is $7,500 for 2026 ($8,600 if aged 50 and older). At certain incomes, the contribution amount is lowered until it is eliminated completely.
While this restricts direct contributions to a Roth IRA, high earners can utilize other options to add to their Roth IRA, such as a backdoor Roth, or explore other retirement accounts.
