Cash Balance Plan vs. Defined Benefit Plan
Both let high earners deduct far more than a 401(k). The difference is how the benefit is defined, and that changes flexibility, cost, and how easy the plan is to live with.
We’ll show you which fits your business.

What’s the difference between a cash balance plan and a defined benefit plan?
A cash balance plan is a type of defined benefit plan. Both are funded by the employer, use an actuary, and allow large age-based contributions.
A traditional defined benefit plan promises a monthly benefit at retirement based on a formula, such as a percentage of pay. A cash balance plan instead credits each participant with a hypothetical account balance: a pay credit each year plus an interest credit. That makes it easier to understand, easier to design for different groups, and easier to roll over at retirement. For most small businesses with employees, it’s the better fit.
Side-by-side comparison
| Cash balance plan | Traditional defined benefit plan | |
|---|---|---|
| How the benefit is stated | An account balance | A monthly benefit at retirement |
| Contributions | Age-based, set by the actuary | Age-based, set by the actuary |
| Different benefits by group | Easy to design | Harder to design |
| Easy for employees to understand | Yes | Less so |
| Payout | Usually a lump sum, can be rolled to an IRA | Annuity or lump sum |
| Best fit | Businesses with employees, multiple owners | Solo owners or owner-only plans seeking the maximum deduction |
How a cash balance account grows
Each year, every participant’s account receives two credits set by the plan document:
- A pay credit: a dollar amount or percentage of pay. Owners can receive a large age-based credit, and staff a smaller percentage.
- An interest credit: a fixed rate, such as 4% or 5%, or a rate tied to Treasury yields, applied to the existing balance.
The plan’s actual investments are pooled. If returns beat the interest credit, future contributions can go down. If they fall short, contributions go up to make up the difference. That’s why cash balance plans are usually invested conservatively, aiming close to the crediting rate, and why investment oversight matters.

Which one should you choose?
A cash balance plan usually fits best if:
- You have employees and want to control their cost
- You have multiple owners or partners who want different contribution levels
- You want a plan that’s easy to explain and administer
A traditional defined benefit plan may fit if:
- You have no employees other than owners and spouses
- You’re older and want to push contributions to the maximum
What both plans have in common
- Contributions are deductible to the business and must be made each year within a range the actuary sets.
- Both work alongside a 401(k). See adding a defined benefit plan to your 401(k).
- Both are meant to be kept for several years, and both can be amended or frozen if needed.
- Professional service practices with 25 or fewer participants are generally exempt from PBGC premiums.

Asked Questions
Is a cash balance plan a defined benefit plan?
Yes. A cash balance plan is a type of defined benefit plan. It expresses each participant’s benefit as an account balance instead of a monthly pension.
Which allows bigger contributions, a cash balance or defined benefit plan?
Limits are similar because both are subject to the same IRS maximum benefit, $290,000 a year at retirement in 2026. A traditional design can sometimes allow more for an older owner with no employees.
Which is better for a business with employees?
Usually a cash balance plan. It makes it easier to give owners larger benefits while giving staff a fair, efficient benefit, and employees find it easier to understand.
How is interest credited in a cash balance plan?
The plan document sets an interest crediting rate, often a fixed rate or one tied to Treasury yields. Actual investment returns above or below that rate affect future contributions.
Can I switch from a defined benefit plan to a cash balance plan?
Often yes, through a plan amendment or by freezing one plan and starting another. Benefits already earned must be protected.
Do I still need a 401(k)?
Yes, in most designs. The 401(k) and profit sharing plan are part of passing nondiscrimination testing and give owners another $24,500 to $72,000 of contribution room.
What happens to a cash balance plan when I retire or close the business?
Participants can usually take their vested account as a lump sum and roll it into an IRA or another plan, which keeps it tax deferred. The plan is then terminated with a final filing.
