The IRS just announced a 2018 maximum 401K contribution limit of $18,500, which is the max you can contribute to a 401K in a given calendar year. This is an increase over the 2017 maximum 401K contribution limits (where it was stuck in its 3rd year in a row at $18,000).
The IRS adjusts maximum contribution limits according to changes in the consumer price index (CPI).
The maximum 401K limit is set annually by the IRS and it applies to your personal employee contributions to both traditional 401K’s and Roth 401K’s (or a shared combination of the two types of accounts, if you have both). It is separate from the maximum employer 401K contribution (which has its own limit). If you have self-employment income, this maximum also applies for the “employee” contribution portion of Solo 401K’s.
2018 Maximum 401K Contribution Limits
The base 2018 maximum 401K contribution limit is $18,500 (an increase of $500).
Similar pension plans, like the 403B, 457B, and government TSP have the exact same maximum contribution limit.
The catch up contribution is only available to those age 50 and older who are trying to “catch up” for retirement in their latter years.
2018 401K Catch-Up Contribution
The 2018 401K catch-up contribution is $6,000 (no increase). This catch-up contribution also stays the same for 403B’s, 457B’s, and the government TSP. The catch-up contribution is in addition to the standard contribution limit, making the total contribution amount $24,500.
Historical 401K Maximum Contribution Limits
How do these maximums compare to previous years? Here’s the IRS’s recent history on maximum 403B, 457B, TSP, and 401K maximum contribution limits over the last few years:
|Year||403B, 457B, TSP, & 401K Contribution Limits (under age 50):||403B, 457B, TSP, & 401K Contribution Limits (over age 50). Includes catch-up contribution:||Total Defined Contribution Limit (employee + employer):|
The max contribution limit has increased in all but eight years going back to its inaugural year in 1987 (over 75% of the time). Five of those eight years without an increase happened in the last 7 years (2010, 2011, 2014, 2016, and 2017). It’s also worth nothing that the maximum 401K contribution limit amount has never declined from one year to the next.
How to Max your 401K
If you would like to make the max 401K contribution (a wise move, especially if your employer offers a 401K match), you’ll need to first do some simple math.
In 2018, for example, take $18,500 and divide it by your total salary or expected wages from your employer. For example, if you make $74,000 per year (before tax), then take $18,500 and divide by $74,000 to calculate the percentage of your pay you would need to contribute to max your 401K.
In the above example, the result would be 0.25, or 25%. Next, work with your HR department or your 401K administrator (often within your 401K account) to update your 401K contribution percentage.
Taking your Retirement Contributions Further
Not everyone will be able to contribute the maximum 401K contribution. If you can, however, it is one of the best things you can do for your financial future, particularly when a possible employer 401K match is at stake. Matching funds are free money and can quickly boost your retirement outlook.
If you do contribute the maximum and want to add even more to your retirement, you can also create a Traditional or Roth IRA (note: the maximum IRA contribution is $5,500 for 2018).
If you have changed employers and have old 401K’s sitting around, you may want to consider a 401K rollover to an IRA or your current 401K, in order to consolidate your 401K’s. You may be able to save money on fees in an IRA versus your 401K.
