401(k) Save the Max Calculator
Find out how much to contribute per paycheck to max out your 401(k) this year.
About the 401(k) "Save the Max" Calculator
Maxing out your 401(k) is a powerful strategy for accelerating your retirement savings. It involves contributing the maximum amount allowed by the IRS each year. This calculator is designed for individuals who want to ensure they hit that maximum limit by the end of the year. It's particularly useful if you've received a raise, got a late start on saving, or simply want to adjust your contributions to take full advantage of your tax-advantaged savings space.
How Is the "Save the Max" Amount Calculated?
The calculation is a straightforward process to determine your required contribution rate for the rest of the year:
- Determine Your Max Limit: First, we determine your personal IRS contribution limit. For 2025, this is $23,000, plus an additional $7,500 "catch-up" contribution if you are age 50 or over.
- Calculate Remaining Contribution Room: We subtract your year-to-date contributions from your maximum limit to see how much more you can save this year.
- Determine Remaining Salary: We calculate your estimated remaining salary based on your annual salary and the number of pay periods left.
- Find the Required Contribution Rate: Finally, we divide your remaining contribution room by your remaining salary to find the exact percentage you need to contribute from each paycheck to hit the max.
Frequently Asked Questions (FAQ)
Does the IRS limit include my employer's match?
No, the annual contribution limits ($23,000 or $30,500 for those 50+ in 2025) apply only to your own employee contributions. Your employer's matching contributions do not count toward this limit. There is a separate, much higher limit for the combination of employee and employer contributions.
What is a "catch-up" contribution?
The IRS allows individuals who are age 50 or older at any point during the calendar year to make additional contributions to their 401(k) above the standard limit. For 2025, this "catch-up" amount is $7,500. This is designed to help those closer to retirement boost their savings.
What if the calculated percentage is too high?
If the required contribution rate is not feasible for your budget, don't be discouraged. The goal is to save as much as you comfortably can. Any amount you contribute is a positive step. The most important first step is to contribute enough to receive your full employer match, as this is an instant, guaranteed return on your investment.
