401(k) savings plan

The Merck U.S. Savings Plan is a 401(k) plan, a voluntary retirement plan provided through Merck that helps you save toward retirement. You fund your personal 401(k) plan account through paycheck contributions. Then, Merck matches a portion of your contributions up to certain limits. You manage how the funds in your account are invested, which means – unlike the pension – you assume the risk associated with gains and/or losses in your account balance.

You are eligible to participate in the 401(k) on your date of hire. Your contributions, company match and earnings are 100% vested immediately.

If you do not actively enroll in the 401(k) within 60 days of your date of hire, you are automatically enrolled as follows:

  • 6% base pay contribution rate on a before-tax basis
  • 6% AIP/SIP contribution rate on a before-tax basis
  • Invested into the plan’s Designated Fund – a target-date fund based on an assumed retirement age of 65
  • Enrolled in the Annual Increase Program with a 1% per year election (until your before-tax base pay and before-tax AIP/SIP contribution rates each reach 10%)

Tip: To maximize your 401(k) match, don’t forget to elect the spillover feature (see Financial planning tools and resources).

Employee contributions

  • You can contribute up to 25% of your total pay*, up to the IRS elective deferral limit, through combined before-tax and Roth after-tax contributions.
  • You can contribute up to 50% of your total pay*, up to the IRS total contributions limit, through combined before-tax, Roth after-tax and traditional after-tax contributions.
  • You may change your contribution elections or stop contributions at any time.
  • You can make an affirmative election under the Annual Increase Program, which will allow your annual increases to continue past the 10% cap, up to the Plan’s maximum of 25%.

Merck contributions

  • Merck provides a company match of $0.75 for every $1.00 you contribute, up to the first 6% of your total pay (and up to IRS limits).
  • To maximize the 401(k) match, you must elect 6% pay PLUS 6% AIP/SIP and elect spillover, which automatically rolls over your before-tax contributions to after-tax contributions once the before-tax contribution limit is reached.

* Total pay is your total annual cash compensation, which includes base pay, commissions, paid cash bonus, overtime and shift differential.

  • Before-tax — Contributions are taken from your pay before taxes come out; lowers your taxable income today.
  • Roth after-tax — Contributions are taken from your pay after taxes come out; lowers your taxable income at distribution because withdrawals and earnings are tax-free.
  • Traditional after-tax — Contributions are taken from your pay after taxes come out; up to 25% of total pay; lowers your taxable income at distribution because withdrawals (but not earnings) are tax-free.
  • Catch-up — If you will be at least age 50 by the end of a year, your annual before-tax/Roth after-tax contribution (elective deferral) limit will be increased by $7,500 (catch-up contribution limit in 2023).

The IRS limits how much you can contribute into your 401(k) each year. The limits are adjusted annually.

The plan offers a three-tiered approach to investing, ranging from fully directed to self-directed:

  • Retirement portfolios: Target date funds based on your estimated retirement date; portfolios adjust risk profile automatically as you get closer to your retirement date. Watch a quick video explaining target date funds.
  • Core funds: Nine investment funds are available
  • Brokerage account: Self-directed brokerage option that provides thousands of investment options beyond the core fund lineup

Note: If you do not elect investment options, your contributions and the company match will default into the plan’s Designated Fund, a retirement portfolio that best matches an assumed retirement age of 65.
