A Part-Time Paycheck Can Cut $100,000 Off What Couples Need To Retire

Retirement does not always have to mean stopping work completely. Even earning a modest amount from a part-time job could make a surprisingly large difference to how much money couples need to save before leaving the workforce.

For this estimate, $10,000 in annual earnings over 10 years is treated as reducing the modeled savings target by $100,000. Here is how this plan could help boost a fixed income. 

Why a part-time paycheck changes the math

The estimates use the widely discussed 4% withdrawal rule, a common retirement-planning guideline that suggests withdrawing about 4% of a portfolio in the first year of retirement and adjusting that dollar amount for inflation afterward.

Under this model, the rule provides a starting point for estimating the nest egg couples may need after accounting for average expenses and Social Security income. The calculation also assumes that one spouse works part time during the first 10 years of retirement.

Earning $10,000 annually over that period adds up to $100,000, which is subtracted from the estimated savings target. Under the same assumption, a part-time paycheck of about $400 per week, or roughly $20,000 per year, would total around $200,000 over 10 years and reduce the modeled target by about $200,000.

The remaining savings target depends on where you live

Although the same part-time income produces the same reduction in every location, the amount couples still need varies considerably by state.

The highest savings targets appear in New Jersey, Hawaii, California, and Washington, D.C., while New York, Washington state, and Massachusetts are also among the more expensive locations. Couples in these areas often need larger retirement portfolios because housing, health care, and everyday expenses cost more than the national average.

Without any earned income, a typical retired couple needs at least $1 million in savings in 23 states and Washington, D.C., based on average spending and Social Security benefits. Adding $20,000 of annual part-time income changes that picture dramatically, leaving only four locations with estimated savings requirements of at least $1 million.

In New Jersey, for example, the estimated target falls from roughly $1.33 million to about $1.13 million. Hawaii, California, and Washington, D.C., remain close behind at roughly $1.07 million each, despite the same $200,000 reduction.

Working early in retirement matters most

The timing of that income might be just as important as the amount. Many retirees who continue working do so during the first several years after leaving full-time employment, when avoiding portfolio withdrawals could have the greatest long-term impact.

Every dollar left invested has more time to compound. Relying on a paycheck instead of investment withdrawals early in retirement may reduce pressure on a portfolio and leave more money available to participate in future market recoveries.

That is particularly valuable when retirement begins during a market downturn. Selling fewer investments at depressed prices gives the remaining portfolio more time to recover.

Part-time work remains common among older Americans

Retirement is also increasingly becoming a gradual transition rather than a single stopping point. According to the Bureau of Labor Statistics, about one in five Americans age 65 and older participated in the labor force in 2024.

Some retirees generate income through consulting or freelance work. Others take seasonal jobs, work a few days each week, or turn long-time hobbies into small businesses.

Even modest earnings could meaningfully reduce the pressure on retirement savings while allowing retirees greater flexibility over when and how much they withdraw from their portfolios.

Social Security affects the calculation

Part-time earnings may also interact with Social Security differently depending on when benefits are claimed.

Workers who receive Social Security before reaching full retirement age may have some benefits temporarily withheld if their wages or self-employment income exceed the annual earnings limit. In 2026, that limit is $24,480 for someone under full retirement age throughout the year. For someone reaching full retirement age in 2026, a higher $65,160 limit applies to earnings before the month they reach that age.

Beginning with the month a worker reaches full retirement age, employment earnings no longer reduce Social Security benefits. Benefits withheld under the earnings test also aren't necessarily lost permanently, as Social Security recalculates benefits at full retirement age to account for months in which benefits were withheld.

The paycheck may not be fully available

Part-time earnings are not the same as extra spending money. Wages may be subject to federal and state income taxes, along with Social Security and Medicare payroll taxes.

Retirees may also face work-related costs such as transportation, clothing, equipment, or meals. Someone earning $10,000 annually may therefore have less than that amount available to replace portfolio withdrawals.

Those taxes and expenses should be considered when estimating how much a part-time job could realistically reduce the savings needed for retirement.

Retirement still depends on where you live

Even after accounting for part-time income, location remains one of the biggest factors determining retirement costs.

Housing expenses vary far more between states than groceries or gasoline, making them one of the biggest drivers of retirement budgets. Couples living in lower-cost states naturally require smaller portfolios than those retiring in coastal markets with higher housing costs.

Part-time earnings lower the required savings target everywhere, but they cannot completely eliminate the impact of local living costs.

Bottom line

Working part time during retirement may not sound like a major financial strategy, but the numbers suggest otherwise.

Earning $10,000 annually during the first 10 years of retirement could reduce a couple's modeled savings target by about $100,000. For retirees willing and able to continue working for a few years, that modest paycheck could make it easier for them to eliminate some money stress.
