What Is a Roth IRA and What This Calculator Shows
A Roth IRA is an individual retirement account funded with money you have already paid tax on. Investments inside it grow without yearly tax, and qualified withdrawals in retirement are completely tax free. That makes it one of the most valuable retirement accounts for people who expect their tax rate to stay the same or rise.
This Roth IRA calculator projects your balance at retirement from your age, current balance, yearly contributions, and expected return. It also checks how much you are allowed to contribute for 2026 based on your filing status and income, adds catch up contributions from age 50, converts the result to today's dollars, and compares the Roth with a regular taxable brokerage account to show the tax you could save.
A return comparison table, a growth chart, and a year by year projection show how contributions and compounding build the account over time.
Who can open a Roth IRA?
Anyone with taxable compensation, such as wages or self employment income, can contribute as long as their income is within the limits. There is no maximum age. A married couple filing jointly can also fund a spousal Roth IRA for a spouse with little or no income, using the working spouse's earnings. Parents can open a custodial Roth IRA for a child who has earned income from a job.
2026 Roth IRA Limits
Contribution limits
| Age | 2026 limit |
|---|---|
| Under 50 | $7,500 |
| 50 and older | $8,600 (includes $1,100 catch up) |
The limit is shared across all your traditional and Roth IRAs, and you cannot contribute more than your taxable compensation for the year. Contributions for a tax year can be made up to the tax filing deadline the following April.
Income phase out ranges (MAGI)
| Filing status | Full | Reduced | None |
|---|---|---|---|
| Single, head of household | Under $153,000 | $153,000 to $168,000 | $168,000+ |
| Married filing jointly | Under $242,000 | $242,000 to $252,000 | $252,000+ |
| Married filing separately* | None | $0 to $10,000 | $10,000+ |
*If you lived with your spouse at any time during the year. Confirm current figures on irs.gov before contributing.

Roth vs taxable account
Today's dollars
The taxable comparison taxes all growth once at the end, which flatters the taxable account slightly; in practice dividends are taxed every year, so the true Roth advantage is usually larger.
How to Use the Calculator: Worked Example
- Enter your ages. Our example investor is 30 and plans to retire at 65, giving 35 years of contributions.
- Check eligibility. As a single filer with $75,000 of MAGI, she is below the phase out range and can contribute the full $7,500.
- Enter balance and contributions. She has $5,000 saved and contributes $7,500 at the start of each year, plus the $1,100 catch up from age 50.
- Set assumptions. She assumes a 7% average return, 15% tax on taxable gains, and 2.5% inflation.
Results for the example
At 65 the Roth IRA is projected at about $1,192,311. She contributed $284,000 including her starting balance, so about $908,311 is tax free growth. The same investments in a taxable account would be worth about $1,056,064 after 15% tax on gains, so the Roth saves about $136,247.
In today's dollars the balance is worth about $502,405. Withdrawing 4% a year would provide about $47,692 of tax free income, or roughly $3,974 a month.
Why starting early matters
| Years of $7,500 at 7% | Contributed | Growth | Balance |
|---|---|---|---|
| 10 years | $75,000 | $35,877 | $110,877 |
| 20 years | $150,000 | $178,989 | $328,989 |
| 30 years | $225,000 | $533,048 | $758,048 |
| 40 years | $300,000 | $1,302,072 | $1,602,072 |
Roth IRA Withdrawal Rules
- Contributions: can be withdrawn at any time, for any reason, without tax or penalty.
- Earnings: tax and penalty free in a qualified distribution, which generally requires age 59ยฝ and five years since January 1 of the year of your first Roth IRA contribution.
- Early earnings withdrawals: may owe income tax plus a 10% additional tax unless an exception applies, such as disability or up to $10,000 for a first home purchase.
- No required minimum distributions: the original owner never has to withdraw, so the account can keep growing or pass to heirs.
Roth IRA vs Traditional IRA
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax break | Tax free withdrawals | Possible deduction now |
| Withdrawals | Tax free if qualified | Taxed as income |
| Income limit | Yes, to contribute | Only for the deduction |
| Required distributions | None for owner | Yes, from age 73 |
A Roth usually wins if you expect the same or a higher tax rate in retirement, and a traditional IRA usually wins if you expect a lower one. Many savers hold both for tax flexibility.
Over the income limit?
High earners sometimes use a backdoor Roth: a nondeductible traditional IRA contribution followed by a conversion to a Roth. Existing pretax IRA balances can make part of the conversion taxable under the pro rata rule, so speak with a tax professional first.
Common Roth IRA Mistakes
- Contributing over the limit. Excess contributions owe a 6% tax each year until removed. Use the eligibility check above before you contribute.
- Leaving contributions in cash. Money deposited into a Roth IRA must be invested to grow; uninvested cash earns little.
- Assuming fixed returns. A 7% average includes good and bad years. Test lower returns in the comparison table.
- Ignoring the five year rule. Opening a Roth early, even with a small amount, starts the five year clock sooner.
- Missing the deadline. You can contribute for a tax year until the filing deadline the next April, but not after.
