Your plan includes Schwab PCRA

Schwab Personal Choice Retirement Account (PCRA) is a self-directed brokerage feature within your 401(k) plan. It lets you invest a portion of your 401(k) balance outside the standard fund menu, into individual stocks, ETFs, or a broader universe of mutual funds. The PCRA is a separate sleeve within your plan, but money held there remains inside your 401(k) and retains its tax treatment.

Who uses it

  • Participants who want exposure beyond the plan's core menu, such as specific sector ETFs, individual stocks, or low-cost index funds not offered in the menu.
  • Participants who want to consolidate the management of their 401(k) alongside other investment accounts.
  • Participants with meaningful balances who want more direct control over allocation.
  • Self-directed accounts can be actively managed by the participant directly, or by an advisor if the participant chooses to work with one.

Important considerations

  • Additional costs. Brokerage windows often carry additional fees, and trading commissions vary by provider and security type.
  • Allocation limits. Many plans cap the percentage of your balance that can be moved into the brokerage sleeve. Some require a minimum balance in the core menu.
  • Plan rules still apply. Loan and distribution rules, vesting schedules, and contribution limits are unchanged. The brokerage window changes what you can invest in, not the underlying retirement account rules.
  • Confirm details with your plan administrator. The specifics of your plan's brokerage window, including which securities are eligible and any account-level fees, are governed by your plan documents.

Why our allocations use only index funds

The actively managed funds in this plan cost more per year than the plan's index funds, which run roughly 0.02% to 0.06%. Decades of research on long-term active fund performance do not support reliable outperformance net of fees, which is why the allocation ideas below may consider using only the low-cost index options.

100% match on the first 6% of eligible pay Contributing less than 100% of your eligible pay leaves part of Black Hills Corporation's match unclaimed.

Estimates assume a constant salary and the match formula shown above. Your actual match depends on your plan's exact terms.

The cost of contributing only --%

On a $60,000 salary, contributing just half the match threshold would leave about -- in employer match unclaimed each year. Invested over 20 years at a hypothetical 7% annual return, that forgone match could have grown to roughly -- (a hypothetical illustration, not a projection). The match is the highest-return contribution you will make all year.
