Essay Nine: Mortgage Debt and 401(k)
Assets in Retirement
Increasingly, many Americans nearing the end of their work life find they have a large mortgage and must choose between paying off the mortgage or contributing more funds to their 401(k) plan. A large number of financial advisors advise their clients to increase 401(k) contributions rather than pay off their mortgage.
My view is that it is essential for people nearing retirement to eliminate their mortgage debt even if this goal requires some reduction in 401(k) contributions. I have two reasons for this view. First, as noted and explained in the previous section 401(k) plans are not capable of mitigating the impact of market down turns at the end of a career or during retirement. Intuitively, a person with no debt is much better able to withstand market downturns than a person with a mortgage. The Wall Street analysts always say don’t sell on a panic the market will come back. Well retirees with a large mortgage often have no choice but to sell.
Second, the financial risk considerations interact with another factor, the tax treatment of 401(k) plans. During working years mortgage interest and 401(k) contributions reduce income tax burdens. During retirement a person with a large mortgage payment and most financial assets inside a 401(k) plan will pay more in tax than a person without a mortgage.
All disbursements from a 401(k) plan are fully taxed at the ordinary income tax rate. A person with no mortgage disburses enough to cover discretionary expenses and taxes A person with a mortgage must disburse enough to cover discretionary expenses, the mortgage and taxes.
The disbursement to cover the mortgage leads to additional taxes because all disbursement from the 401(k) plan is taxed. MOREOVER, THE DISBURSEMENT ON FUNDS USED TO COVER THE TAX ON THE 401(K) DISBURSEMENT IS ALSO TAXED.
Part of Social Security is taxed for people with income over a certain threshold. A quick way to find out if part of Social Security benefit is taxable is to compare your income to the threshold for your filing status — $25,000 for filing status single and $32,000 for filing status married.
Higher disbursements from the 401(k) plan can increase your adjusted gross income beyond the threshold and increase the amount of the Social Security benefit subject to tax. Of course any 401(k) disbursement used to pay the income tax is also taxed.
So let’s take a household with all financial assets in their 401(k) plan with a $30,000 annual mortgage. This monthly mortgage is $2,500, not huge. Let’s assume that the person has to pay around $1,000 more in tax on Social Security benefits because of the additional disbursement to pay down the mortgage. A first order approximation of the amount of additional tax needed because of the additional $31,000 disbursement is $31,000 x the marginal tax rate for the taxpayer. For most filers the marginal tax rate would be around 25 percent in 2014.
So the taxpayer with the mortgage and the additional tax burden because of the additional 401(k) disbursement will probably disburse $39,000 more per year from their 401(k) plan.
This analysis puts a whole new wrinkle on the question how much money does one have to save in their 401(k) to have a secure retirement. The answer is much more if you have not paid off your mortgage.
Note that the disbursement to cover the unpaid mortgage must occur whether the market falls or rises.
Many people who choose to add to their 401(k) plan rather than pay off their mortgage prior to retirement are going to have sell their home and downsize. Downsizing may make sense but most people don’t want to downsize until they are fairly old.
Some people who end up selling their home may choose to rent rather than buy a new home. The main risk of choosing to rent throughout retirement is that home prices and rents may rise. This exacerbates longevity risk.
Downsizing should be a choice not an outcome from a failed financial plan or worse the result of financial advisors putting their interests over your interests
Concluding thoughts on mortgage debt in retirement: An increasing number of households are retiring prior to their mortgage being entirely paid off. Surprisingly, the existence of a mortgage in retirement is often consistent with a financial plan developed by a financial planner. Many financial analysts and planners advise their clients to increase savings in their 401(k) plan rather than retire their mortgage.
These financial planners are not being upfront with their clients. Retirees with mortgage debt and all or most financial assets in a 401(k) plan are at the whim of the market and have a substantial tax obligation. The advice that put people in this position is in my view a form of malpractice.
Appendix to Essay on Mortgage Debt and 401(k) Assets in Retirement
The issue of whether to pay off a mortgage or contribute to a 401(k) plan for an older worker is related to the issue of mortgage choice, especially for older homebuyers. The following question addresses the interaction between mortgage choice and 401(k) investment strategy for an older worker.
Question: A 50 year-old person is buying a house and must choose between a 15-year mortgage and a 30-year mortgage. The mortgage choice will impact how much money the person can contribute to his or her 401(k) plan.
The person makes $80,000 per year. The initial mortgage balance is $400,000. The person’s 401(k) balance at age 50 is $200,000. The 30-year FRM rate is 3.9 percent and the 15-year FRM rate is 3.1 percent.
Discuss the advantages and disadvantages of two strategies (1) taking the 30-year FRM and investing 15% of salary in the 401(k) plan and (2) taking the 15-year FRM and investing 5% of salary in the 401(k) plan.
Let’s start with a reiteration of mortgage choice issues a subject previously broached in essay four.
Observations and Thoughts on Mortgage Choice Issues:
- The monthly payment on the 30-year FRM is nearly $900 less than the monthly payment on the 15-year FRM. The higher mortgage payment on the 15-year FRM will all else equal require the person who chooses the 15-year FRM to make a smaller 401(k) contribution than the person who chooses the 30-year FRM.
- After 15 years the 15-year FRM is completely paid off. The remaining loan balance on the 15-year FRM is around $257,000.
- Note that gains from the quicker pay down on the 15-year mortgage are not dependent on market fluctuations. The gain from debt reduction occurs regardless of whether the market is up or down and regardless of when bear or bull makers occur.

Observations and Thoughts on Two 401(k) Contribution Strategies:
As noted in essay eight, the final 401(k) balance after 15 years depends on both the rate of return of the market and the sequence of the returns in the market. Outcomes are presented for two market scenarios. The first involves 7% returns for the entire 15-year period. The second involves 7% returns for 10 years followed by -4% returns for 5 years.
- The difference in the final 401(k) balances (high contribution minus low contribution) under the 15-year bull market scenario is around $211,000.
- The difference in the final 401(k) balance (high contribution minus low contribution) under the 10-year bull and 5-year bear scenario is around $131,000
|Analysis of Different 401(K) Contribution Strategies|
|5% Contribution Rate||15% Contribution Rate||Difference|
|7.0% Return for 15 Years||$675,442||$886,752||$211,309|
|7.0% Return for 10 years followed by -4.0% return for 5 years||$394,339||$525,090||$130,751|
The initial balance in the 401(k) plan for both scenarios is $200,000.
Additional insights on the tradeoff between 401(k) contributions and mortgage retirement:
- The 30-year mortgage/high 401(k) contribution strategy results in major tax savings during working years compare to the 15-year mortgage/low 401(k) strategy. All mortgage interest is tax deductible and the 401(k) contribution is not taxed.
- The 15-year mortgage/low 401(k) contribution strategy results in major tax savings during retirement compared to the 30-year mortgage/high 401(k) strategy. The previous example in this section demonstrated exposures for the person with mortgage debt in retirement when the person is dependent on 401(k) disbursements. Remember all disbursements from a conventional 401(k) plan including disbursement used to pay the mortgage and disbursements used to pay taxes are fully taxed at ordinary income rates. By contrast, the money gained from paying off the mortgage and most capital gains on owner-occupied real estate is not taxed.
- Financial risks associated with a bull market persist through retirement as long as the saver allocates 401(k) assets into equity.
