How Much Can I Contribute to an IRA?

An IRA calculator projects the future value of your individual retirement account from your current balance, annual contributions, time horizon, and expected return.

Traditional vs. Roth

An IRA is a tax-advantaged retirement account you open yourself. A traditional IRA may deduct contributions now and taxes withdrawals later; a Roth IRA takes after-tax contributions and pays out tax-free in retirement. Roth generally wins if you expect a higher tax rate later. Both let investments grow without annual tax drag, which powers long-term compounding.

Contribution limits and growth

The IRS sets an annual IRA limit that changes over time, with a catch-up amount at 50 and older, and Roth eligibility phases out at higher incomes. The keys to growth are contributing consistently, ideally the maximum, and starting early so compounding has time to work. Small annual contributions can grow into a large balance over decades.

How to use it

  1. Enter your current IRA balance.
  2. Enter your annual contribution.
  3. Set years to retirement and expected return.
  4. See the projected balance and growth.
