'It’s really helped with cash': The shaky economy has Americans flocking to sell their blood plasma for extra income. How much can you make?

In 2025 alone, Americans pocketed about $4.7 billion from more than 75 million plasma donations — over 200,000 donations per day, according to estimates compiled by the Georgetown Blood and Plasma Research Group (1).

Collections rose 8.4% last year and are projected to grow another 11% this year, signalling that this little-discussed side hustle is expanding rapidly.

Middle-class donors among those at plasma donation centers

Behind those numbers are people from across the income spectrum, including many middle-class families.

An NBC News report describes a couple in rural Idaho who sell plasma to cover expenses such as car repairs and medical bills (2). They have an annual income of $120,000.

Their story reflects a broader pattern economists sometimes call a “K-shaped” economy (3), where wealth grows at the top while middle- and lower-income households feel squeezed.

Even pop culture is playing a role. According to Rolling Stone (4), Harry Styles fans have turned to plasma donations specifically to afford expensive concert tickets that can be priced as high as $1,000.

The magazine documented students and young adults donating multiple times a month to save up for events they see as once-in-a-lifetime experiences.

Online forums suggest the trend may be noticeable on the ground. One Reddit user wrote (5) their local clinic is “about five times busier than it was a few years ago,” describing full stations and waiting lines even on weekday afternoons.

Another commenter said donating twice weekly has “really helped with cash (6),” and provided a reliable supplemental income.

Pros and cons of plasma donation

Hospitals use plasma for trauma care and to produce medications that treat immune disorders and bleeding conditions.

Plasma accounts for about 55% of the total blood volume (7). It is the liquid component of blood that carries proteins, antibodies and nutrients.

During plasma donation, clinicians draw blood and use a machine to separate the plasma, returning the remaining blood components to the donor.

Payments vary widely by location, weight and demand. Promotional rates for new donors can total $700 in the first month (8).

Interestingly, frequent donors can earn up to $1,000 per month (9). Some centers offer bonuses for returning within the same week.

Health authorities say the process is generally safe when done at certified facilities (10).

But donors must meet screening requirements and follow staff instructions for a safe and successful procedure.

The U.S. Food and Drug Administration allows for-profit plasma centers to collect plasma up to twice per week.

But the American Red Cross recommends no more than one donation in 28 days.

A Carolina News & Reporter investigation found medical specialists warning that donating too often may reduce important blood proteins or antibodies in some people, potentially leading to (11):
