Many seniors see retirement as a pause, not the finish line. AARP's latest survey of adults 50 and over found that 7% of retirees returned to work in the past six months, up from 6% the previous summer. The reason isn't boredom. Instead, they want to get ahead financially.
A total of 48% said making money was their primary motive, while just 14% said they wanted to stay active.
Getting hired is another matter. The same survey found that 67% of older workers believe finding a new job right now would be difficult, and 35% of them point to age discrimination as the main reason.
So where are retirees actually landing? It depends on what they have to offer. Here are the four tiers, with what each pays.
Licensed professional work
If you have current credentials, you've been dealt the strongest hand. Advanced practice nursing and pharmacy are two examples, although many retirees may shun long hours on their feet.
Median pay for nurse practitioners is $134,920 a year, and for pharmacists, it is $140,910 a year, according to the Bureau of Labor Statistics (BLS). Since these are licensed roles, part-time and per diem arrangements could provide you with a few shifts a month at a professional rate.
Consulting and advisory roles
If you want to return to your pre-retirement career, you don't have to re-apply for your old job. Engineers, finance veterans, compliance specialists, and expert witnesses have the perfect background to become advisors or consultants.
Expert witness work shows the upside: SEAK's 2024 fee survey found median hourly rates of $450 for file review, $475 for depositions, and $500 for court testimony.
Part-time engineering consultants in IEEE-USA's 2025 survey reported regional median rates as high as $250 an hour.
Now, bear in mind that hourly rates aren't income. As a consultant, you must spend unpaid time finding clients unless you contract for a former employer.
Administrative and hearing officer positions
Administrative law judges, adjudicators, and hearing officers had a national median of $117,860 a year in May 2025, though this higher tier didn't apply in all geographical locations.
These jobs are scarce, since projections point to a slight decline in the field, so retirees with legal or regulatory backgrounds may need to be patient during their job search.
Retail, customer service, seasonal, and school-adjacent jobs
These jobs represent the lowest-barrier tier, but they work for flexible retirees looking for something to do rather than would-be high earners. Retail salespersons earn a median of $35,410 a year, customer service representatives $44,770 a year, and cashiers $16.66 an hour. Seasonal retail usually pays near that cashier level.
School-adjacent jobs may offer higher pay. Recent district postings show substitute bus drivers at roughly $30 an hour. These jobs may require extras, such as a commercial driver's license.
What happens to your paycheck
Knowing what potential jobs pay helps, but pay isn't the same as take-home wages, especially if you're already collecting Social Security.
The earnings test
In 2027, if you're under full retirement age all year, you may earn up to $25,560 before Social Security withholds $1 for every $2 above that. In the year you reach full retirement age, the limit is $67,920, with $1 withheld for every $3 above it, counting only earnings before the month you reach that age. Full retirement age is 67 if you were born in 1960 or later.
For example, a 63-year-old collecting benefits takes a retail job that pays $35,410. That's $9,850 over the limit, so the Social Security Administration withholds $4,925 in benefits.
That money isn't lost. Social Security recalculates your benefit at full retirement age to account for the months it withheld, so your monthly check gets bigger. After that age, the earnings test no longer applies.
The Medicare lookback
Medicare sets income-related surcharges using your income from two years earlier. Your 2027 premiums are based on your 2025 tax return, which means work you take on in 2027 would shape your 2029 premiums.
For 2026, surcharges start above $109,000 for single filers and $218,000 for joint filers. Even $1 across that line triggers the full bracket. A full year at a nurse practitioner's median pay could put a single filer into that bracket, while retail work wouldn't even come close. If your income drops after you stop working, you may ask Social Security to reconsider using Form SSA-44.
Bottom line
Unretirement is mostly about money, and any credentials you hold may determine your first move. If you still have a current license or professional credential, start there. Check your renewal and continuing-education status, then contact your former employer, a staffing agency, or your professional network about part-time, per diem, or project work. That's where the pay gap works in your favor.
If you're starting fresh, begin with the school district or retail employer closest to home. Ask about substitute lists, seasonal hiring, and flexible hours, since the application and background-check process may take weeks.
Before you accept any offer, estimate your total yearly earnings and compare them with the $25,560 and $67,920 limits. Then check where your income would land against the Medicare thresholds two years from now. A few hours a week could make a real difference, but a few hours too many might be one of the costliest financial mistakes you make.
