10 Best Free (or Cheap) Online Classes for Seniors and Retirees
Unlock new skills and keep learning for free (or nearly free). These online classes are perfect for curious, knowledge-loving retirees.
Every state in the U.S. offers free or almost free college courses for retirees — either on-campus or online; some for credit and some for just the fun of it.
Either way, using your brain to learn new things, gain a new talent, or pass the time can help you stay ageless, curious, and engaged. And learning new skills can help you stay youthful, boost your cognitive function and memory, and safeguard your emotional well-being.

An older, but still relevant, study published on the National Library of Science website indicates that older adults’ participation in lifelong learning is independently and positively associated with their psychological well-being.
A May 2025 Scientific American study found that gaining new knowledge sustained improvements in attention and working memory among adults aged 58 to 86, effectively countering age-related mental declines. After a year, participants achieved skill levels equivalent to those of people 50 years younger.
Harvard Health (updated December 2025) notes that building cognitive reserve through lifelong education, curiosity, and mentally engaging activities — like learning new skills — helps the brain improvise and maintain functions such as focus and memory despite age-related changes.
Nonprofits such as Chicago-based Mather help older people find a new sense of purpose in retirement. By providing thousands of hours of virtual programming, the organization helps older adults stay active and creative, forming meaningful connections and discovering new skills.
So, if your goal is to stay active and engaged, but you're not interested in attending in person at a university, then check out these 10 online learning platforms offering courses that range from learning a new language to private markets and investment strategies, and nearly everything in between.
Some platforms charge a fee per course, while others are offered at no charge.
1. AARP Senior Planet
If you want a program specifically geared to older adults, check out AARP's Senior Planet. From technology and health to finance and creativity, you're likely to find a class that meets your learning style, making the experience fun and educational without the stress of weekly tests.
On the site, you'll also find a guide that includes helpful tips and tricks on how to navigate online learning platforms and maximize the benefits of these courses.
2. Open Learning Initiative
The Open Learning Initiative is a series of independent learner courses through Carnegie Mellon University. The courses are self-paced and self-guided. You can't earn credit for the classes you take, but they do provide an opportunity to gain new knowledge and learn new skills. Study a new language, upskill your understanding of math, or explore human anatomy so you can impress the doctor on your next visit. Many classes are free, but some charge a small fee per class.
3. EdX
EdX offers 70,000 free online education courses from MIT, Berkeley, Harvard and other well-known colleges and universities, serving more than 140 million learners.
The courses are self-paced, meaning you can learn at your own speed. Topics include nutrition science, private markets, AI and investment strategies. Want something a bit flashier? Try introduction to music theory or graphic design.
You won't pay for EdX open courses when you enroll in the free audit track; however, this version doesn't offer certificates and you won't be graded for your work. If you want to earn a certificate, there is a fee that ranges from about $90 to $300 or more, depending on the course — much less than a class at a two- or four-year college.
4. Coursera
If you want to further your knowledge with degrees and professional certificates from world-class universities like Duke and the University of Michigan, then Coursera might be for you. It offers thousands of paid and free online courses. For example, you can learn the basics of bookkeeping and balance your budget like a pro, or learn basic grammar in less than four weeks. You can start with a free trial, but you'll pay a small fee after the trial ends.
5. LinkedIn
LinkedIn is best known as a social media platform that offers networking opportunities for working adults. But the platform also offers a mixed bag of courses — 26,500 by over 3,900 industry experts and thought leaders — through LinkedIn Learning. Develop the critical skills you need to start a new career if you decide to unretire or learn something new to keep up with the grandkids.
Even if you have no intention to return to work, you can stay on top of the latest advancements in AI or learn how to create a spreadsheet in Excel, which can come in handy when preparing next month’s budget.
6. Academic Earth
Academic Earth is a good resource for retirees looking to dive into high-quality education from top universities like Princeton and Oxford. The self-paced, at-home setup with no time or location restrictions is perfect for flexible online learning. Subjects (over 750) available to study include business, science, humanities and law. Anything specific you want to explore, free of charge? That’s another advantage for retirees on a budget.
7. Skillshare
Skillshare is an online learning community where you, along with your kids and grandkids, can discover a new skill, take a new course, or even teach a class. Explore a new passion or hone your talent with classes that range from beginner to expert. Pricing varies (after your initial free trial ends), and you’ll have to create an account to see how much each course costs.
For instance, after the 7-day free trial, you will pay a recurring annual membership charge of $167.88 (plus tax, where applicable), automatically applied to your payment method. Still, when you consider that the average cost of a college course is approximately $1,234 at public four-year universities, this annual charge is very reasonable.
8. Great Courses
The Great Courses offers hundreds of courses across almost every subject, from Ancient Cities of the Mediterranean and a Field Guide to the Planets to Learning French and the Art of Travel Photography. Taught by leading experts and professors, courses offer self-paced learning via Apple TV, Kindle Fire, or DVD. Each course is a one-time purchase that includes lifetime access. At various times of the year, you can also find discounts on many of the best courses, so check back.
9. YouTube
YouTube is an amazing platform (and personal favorite) with hundreds of videos on a variety of topics. You can pick up a new hobby, learn to cook pasta, find out about climate change, or take a yoga class. Most classes are free, but some charge a small subscription fee. The only drawback? They are videos. So while you can bookmark your favorites, they might not be available to view forever.
10. Learn Out Loud
Learn Out Loud is a one-stop destination for audio and video learning. It has over 50,000 audiobooks, podcasts, and videos covering politics, history, business, science and more. Most courses are free. Like YouTube, the drawback is that everything is audio or video, so you can’t save a course transcript for later review. Even so, with such an extensive library of learning opportunities, it’s hard to pass it up.
Why take an online course in retirement?
Retirement is the perfect time to keep your mind sharp and chase your curiosity. If you're ready to learn something new, explore these top online platforms.
