Understanding How Annual Cash Balance Plan Contributions Are Really Calculated
Many physicians are told that a Cash Balance Plan allows them to make a large annual tax-deductible contribution often $200,000, $300,000, or even more. While that is true, many are surprised to learn that their annual contribution is not simply a fixed amount that they choose every year.
A Cash Balance Plan is a defined benefit pension plan, which means annual contributions are determined by an actuarial funding calculation. The goal is not merely to maximize a tax deduction today it is to systematically fund the retirement benefit you want tomorrow.
The Three Factors That Determine Your Annual Contribution
Your annual Cash Balance Plan contribution is primarily driven by the relationship between:
1. Your Cash Balance Liability (What the Plan Owes You)
Your Cash Balance account is a hypothetical retirement account that grows annually based on two components:
- Pay Credit – the annual contribution amount allocated to your account under the plan design.
- Interest Credit – the annual growth credit applied to your existing balance.
Example:
A 55-year-old physician has:
- Beginning Cash Balance account: $1,000,000
- Annual Pay Credit: $250,000
- Interest Credit: 5%
During the year:
- Existing balance grows by 5% = $50,000
- New Pay Credit = $250,000
The plan liability increases by $300,000
That increase must ultimately be supported by assets inside the pension trust.
2. Investment Performance (What Your Assets Actually Earn)
The pension trust holds real investments that rise and fall with the markets.
For example:
- Beginning assets: $1,050,000
- Investment return: 10%
- Investment gain: $105,000
The plan now has approximately $1,155,000 in assets before any new contribution.
Because investments performed well, the physician may need to contribute less than expected to maintain proper funding.
3. The Plan’s Funding Position
At year-end, the actuary compares:
Cash Balance Liability vs. Pension Trust Assets
Example:
Liability
- Beginning balance: $1,000,000
- Interest credit: + $50,000
- Pay credit: + $250,000
Total Liability: $1,300,000
Assets
- Beginning assets: $1,050,000
- Investment growth: + $105,000
Total Assets: $1,155,000
The difference is approximately $145,000 and the required contribution is $145,000
In reality, the calculation also considers IRS funding rules, actuarial assumptions, funding corridors, and minimum and maximum deductible contribution limits.
Why Some Physician Cash Balance Plans Become Unpredictable
One of the most common issues we see when reviewing small physician Cash Balance Plans is a mismatch between the plan’s interest crediting rate and its investment strategy.
For example:
A physician may have a plan that credits participants a fixed 5% annual return, but the pension assets may earn:
- +15% in a strong market year
- -10% during a difficult market year
The result can be a growing gap between assets and liabilities.
When investments outperform the fixed crediting rate:
- The plan can become overfunded.
- Annual contributions may need to be reduced.
- The physician may lose valuable tax deductions.
- Excess assets at plan termination can create significant tax consequences.
When investments underperform the fixed crediting rate:
- The plan may become underfunded.
- Required contributions may increase.
- Retirement goals may become harder to achieve.
A Modern Approach: Market Return Crediting
Recent regulatory changes have expanded the ability of Cash Balance Plans to use Market Return Crediting (MRC) designs.
With a properly designed MRC plan, the interest credited to the physician’s Cash Balance account is tied to the performance of the underlying investments.
In simple terms:
When assets go up, liabilities generally go up.
When assets go down, liabilities generally go down.
This alignment can create:
- Better asset-liability matching
- More predictable funding outcomes
- Reduced risk of chronic overfunding or underfunding
- More efficient use of tax-deductible contributions over time
MRC is not appropriate for every physician, but many established plans designed with a fixed crediting rate should be evaluated to determine whether a modern crediting design may improve long-term results.
The Biggest Misunderstanding About Cash Balance Plans
Many physicians believe:
“My Cash Balance Plan contribution is $300,000 per year.”
In reality, the correct statement is:
“My plan is designed to achieve a retirement objective, and my annual contribution will change based on my liabilities, investment results, and funding status.”
The most successful Cash Balance Plans are not necessarily those with the largest annual contributions. They are the plans where the plan design, investment strategy, and actuarial funding strategy work together to consistently deliver the physician’s retirement goals.
Is Your Cash Balance Plan Optimized?
Many small physician Cash Balance Plans receive excellent tax planning advice but limited ongoing fiduciary oversight of the relationship between:
- Investment performance
- Interest crediting method
- Funding status (FTAP and AFTAP)
- Annual contribution stability
- Long-term retirement outcomes
At Physicians Pension Fiduciary, we perform an independent Cash Balance Funding Risk Review to identify whether a physician’s plan is properly aligned or whether hidden risks of overfunding, underfunding, or contribution volatility may exist.
