How Much Should I Contribute to My IRA Each Month?
Divide the annual IRS limit by 12: a $7,000 limit works out to about $583 a month — and consistency matters more than the exact number.
At a glance
Start with the Annual Limit, Divided by 12
The simplest target is the IRS annual IRA contribution limit split into monthly deposits — for example, a $7,000 annual limit works out to about $583 a month (or $538 if you round down and top up in December). Savers 50 and older get a higher limit with catch-up contributions. Limits are adjusted periodically, so check current IRS guidance each year and divide whatever the limit is by 12.

What $7,000 a Year Builds at 7%
The calculator above takes annual contributions, so the figures below use $7,000 deposited each year at a 7% average return:
| Years Contributing | Total Deposited | Projected Balance | Share That Is Growth |
|---|---|---|---|
| 20 years | $140,000 | $286,968 | 51% |
| 25 years | $175,000 | $442,743 | 60% |
| 30 years | $210,000 | $661,226 | 68% |
| 35 years | $245,000 | $967,658 | 75% |
Notice the growth share climbing: the longer you contribute, the more compounding does the work for you. Maxing out for 35 years approaches the million-dollar mark on $245,000 of actual deposits.
Can't Afford the Maximum? Contribute Anyway
Half the limit — about $292 a month against a $7,000 cap — still builds roughly $484,000 over 35 years at 7%, exactly half of the full-limit result. Contribution amounts scale linearly, so anything you automate is worth automating. A common escalation strategy: start with what fits your budget now, then raise the monthly amount every time you get a raise.
Why Monthly Beats a Year-End Lump Sum
Depositing $7,000 every December 31 means each dollar waits up to a year before it starts compounding. Spreading the same total across monthly deposits gets every dollar invested sooner, and over 35 years the difference compounds into tens of thousands of dollars. Set up an automatic transfer for the day after each paycheck and the decision is made for you.
Frequently Asked Questions
Can I contribute to an IRA if I have a 401(k) at work?
Yes, anyone with earned income can contribute. However, if you or your spouse are covered by a workplace plan, the tax deductibility of traditional IRA contributions phases out above certain income levels — check the current IRS thresholds.
What's the deadline for IRA contributions?
You can contribute for a given tax year up until the federal tax filing deadline the following spring — typically mid-April. Contributions for last year and this year can even be made in the same deposit if you designate the years correctly.
Should I contribute to an IRA or pay off debt first?
High-interest debt like credit cards usually comes first — paying off a 20% APR balance beats a 7% expected investment return. But capture any employer 401(k) match first, since that's an instant 100% return.
What happens if I contribute more than the limit?
Excess contributions trigger a 6% IRS penalty for every year they remain in the account. If you over-contribute, withdraw the excess plus its earnings before the filing deadline to avoid the penalty.
