Cash Balance Plans Explained: How They Work and When They Make Sense

David K. Aneja, Retirement Plan Solutions & Strategic Relationships Manager

What is a Cash Balance Plan?

A cash balance plan is a hybrid retirement account. It acts like a traditional pension plan where the employer promises a specific benefit, but it looks like a 401(k) with a hypothetical individual account balance.

How does it work?

  • Pay Credit: The employer adds a set percentage of your annual pay or a flat dollar amount into the account.
  • Interest Credit: The account earns a guaranteed annual return, either at a fixed rate or tied to an index like Treasury bonds.
  • Employer Risk: The employer manages the pooled funds and takes on all investment risk. Market drops do not lower your promised balance.
  • Payouts: At retirement or when leaving the job, you can take the balance as a lump sum or convert it to a lifetime annuity.

Why Cash Balance instead of a 401(k)?

Cash Balance plans allow much higher contributions than 401k plans do, since they are pension plans. The downside is that pension plan contributions are mandatory, sizeable, and inflexible. Business downturns are unforgiving to pension plans.

Why Cash Balance instead of in addition to a 401(k)?

Cash balance plans are often implemented beside a 401(k) plan to allow for employees to defer and receive a match in addition to their cash balance plan benefits. Often the plans are paired together to allow for the cash balance plan to discriminate in favor of the HCEs while providing offsetting benefits to the NHCEs in the 401k plan.

When does a Cash Balance plan make sense?

Ultimately, a Cash Balance plan – or any pension plan – only makes sense if you meet the following criteria:

  • The primary target beneficiaries, one or more HCEs/owners, are in their 50s or older
  • The rank-and-file workforce is younger
  • The business can afford large contributions even if there’s a downturn
  • The HCEs/owners want more benefits than the statutory limits allow a 401(k)

Qualified Plan Design is an active, growing field, as much an art as a science. Chances are that a skilled TPA can create a plan design that meets the needs of your workforce and owners.
