Are You Getting Your Full 401(k) Employer Match?

Your savings rate may not earn everything your employer offers.
If your employer matches your 401(k) savings, you earn the full match by saving at least a certain percentage of your pay. A match is money your employer adds when you save, and each plan has its own terms. Some employers enroll you automatically at a preset rate until you change it. That’s the default rate, and since they set it separately from the match, it may fall below what earns the full match.
Below, we’ll run one example so you can check your own rate, then explain where to find your plan’s terms.
How Matching Formulas Work
A matching formula is the rule your retirement plan uses to turn what you save into what your employer adds.
Plans vary, so here’s a hypothetical example:
The employer adds 50 cents for every dollar you save, up to 6% of your pay. We’ll pair it with a $60,000 yearly salary.
If you save 3% of your pay, say because your employer automatically started you there, that’s $1,800 a year. Since the employer adds 50 cents per dollar, the match is $900.
If you save 6%, that’s $3,600 a year, and the match is $1,800, the most this formula pays. Saving more than 6% wouldn’t raise the match.
Together, your savings and the match come to $2,700 a year at 3% and $5,400 at 6%. So staying at 3% would leave $900 a year in match unclaimed.
To try the math with your own numbers, you’ll need your salary and savings percentage (from your pay stub or plan statement), plus your plan’s formula. You’ll usually find that in the Summary Plan Description, a booklet that explains the plan’s rules in plain terms.
Eligibility and Vesting
Saving enough isn’t the whole story, since two rules also affect your match. Eligibility is when you can start in your plan. Vesting is when your employer’s contributions become yours to keep.
Look for these four things in your plan’s Summary Plan Description:
- Which employees the plan covers
- Any age or time-on-the-job requirement for joining
- The matching formula
- The vesting schedule
A plan can require you to be at least 21 and to have worked there a year before you join. Some set a lower bar. For the match, an employer can require three years before you own all of it. Or it can use a gradual schedule that reaches 100% after six years. Automatic enrollment plans that require an employer contribution vest faster, at two years. If you leave before you’re vested, you may lose part of the match, but your own savings stay yours either way.
Try This Today
Pull up your plan’s Summary Plan Description and find the matching formula. Then compare the highest matching percentage with the percentage you’re saving now, which you can find on your pay stub or plan statement. If your rate falls below that percentage, you may be leaving some match on the table.
Keep in Mind
Our example shows just one way a match can work, and yours may differ. Maybe there’s a waiting period before you can join, or a different vesting schedule. That’s normal. Your plan administrator can walk you through yours, and the plan documents have the final say.
