Cash Balance vs. Traditional Defined Benefit
A cash balance plan is a defined benefit plan under the same section of the Code, with the same limits, so the comparison is between the traditional annuity-style design and the account-style one. This guide covers what differs day to day: communication, portability, and how each behaves at termination.

| Feature | Traditional defined benefit | Cash balance |
|---|---|---|
| Benefit statement reads as | "$X per month starting at 65" | "Your account balance: $X" |
| Participant comprehension | Poor — annuity language baffles staff | High — looks like a 401(k) balance |
| Payout at termination/exit | Annuity-first; lump sums need conversion math | Balance rolls cleanly to an IRA |
| Age discrimination optics | Accruals concentrate late in careers | Level pay credits test cleanly across ages |
| Modern usage | Legacy plans; rare for new small designs | The default for new owner plans |
Both plans live under the same section of the law, share the same contribution and benefit limits, and require the same actuary. What differs is the packaging: a traditional defined benefit plan promises a monthly annuity at retirement ("60% of final average pay at 65"), while a cash balance plan states each participant's benefit as an account balance that grows by pay credits and a guaranteed interest credit.
The packaging matters more than it sounds, for communication, for portability, and for how the plan behaves when it ends.

What's identical
The tax mechanics don't move: identical IRS maximums (the 2026 limits in the table above), the same actuarial funding requirements, the same deduction treatment, the same ability to pair with a 401(k), and the same nondiscrimination testing. At the same age and compensation the ceilings match, so the choice between the designs never turns on deduction size.
What's different
The differences are experiential, and they compound over a plan's life:
Why new plans are almost always cash balance
For an owner covering employees, the account format solves the communication problem that sank traditional pensions: staff can see a number that grows, which makes the benefit feel real, aids retention, and keeps the annual notices legible. When the plan eventually terminates (every owner plan does), balances roll to IRAs without annuity-conversion friction. The traditional design still appears where a fixed final-pay promise fits the goal, and in the fully insured 412(e)(3) structure, where guaranteed contracts express the benefit.
Same pension framework
Both designs use the same actuarial funding, deduction, testing, and benefit limits.
Account-style benefit
A cash balance plan expresses the pension as a hypothetical account that grows over time.
Clearer communication
Participants can follow a visible balance instead of translating a future monthly annuity.
Simpler exit experience
At termination, account balances can roll to IRAs without an annuity-conversion step.
Frequently asked questions
Is a cash balance plan legally a defined benefit plan?
Yes — it is a defined benefit plan that expresses the benefit as a hypothetical account balance. It files the same forms, uses the same limits, and needs the same actuary as a traditional pension.
Do the two designs have different contribution limits?
No. Both fund a benefit up to the same IRS annual cap, so an owner's maximum contribution is the same under either design at the same age and compensation.
Can a traditional defined benefit plan be converted to cash balance?
Yes. Conversions are common, and participant-protection rules govern how accrued benefits carry over. It is actuary-led work, often done when a legacy plan's communication or payout mechanics have become a burden.
Which design does MyPensionTree typically build?
Cash balance for market-invested plans, and 412(e)(3) fully insured structures where carrier-backed guarantees (subject to the issuer's claims-paying ability) and maximum deductions are the goal. Traditional annuity-style designs mostly appear as legacy plans we take over or convert.
