10-Year Cost of Buying vs. Borrowing Books

The power of the library choice compounds over time. Here is what a reader spending on books at various levels would save over a decade by switching to library borrowing:

Reading Level Books/Year Annual Cost (buying new) 10-Year Cost Library Cost 10-Year Savings
Light reader 12 $228 $2,280 $0 $2,280
Average reader 24 $456 $4,560 $0 $4,560
Avid reader 48 $912 $9,120 $0 $9,120
Heavy reader 96 $1,824 $18,240 $0 $18,240
Family (children + adults) 180+ $3,420+ $34,200+ $0 $34,200+

These figures assume average trade paperback pricing ($19) and do not include the additional savings from ebooks, audiobooks, and digital services that come with a library card. The real 10-year savings could easily be 2 to 3 times higher when all library services are factored in.

Barnes & Noble vs. Library: Is a B&N Membership Worth It?

Barnes & Noble's Premium Membership costs $39.99 per year and provides 10% off nearly all in-store and online purchases. This is a legitimate discount for book buyers, but how does it compare to a library card?

Metric B&N Premium Membership Public Library Card
Annual cost $39.99/yr $0 (free for residents)
Book discount 10% off cover price 100% off (free to borrow)
Ebook access NOOK ebooks at retail price Free via Libby (thousands of titles)
Audiobooks Purchase required ($15-$35) Free via Libby/Hoopla
Streaming movies Not included Free via Kanopy & Hoopla
Research databases Not included Free (JSTOR, ProQuest, etc.)
Cost for 48 books/yr ($19 avg) $859 ($39.99 + $820.80 discounted) $0
Annual advantage Saves $91 vs. no membership Saves $859 vs. B&N membership
Verdict: A B&N Premium Membership saves you money compared to paying full price at B&N — but only if you buy books there regularly. A library card saves you nearly everything, because borrowing is free. The library wins on price for any reader who is willing to wait for popular titles or use interlibrary loans.

Amazon vs. Library: The Real Comparison

Amazon is the dominant book retailer in the U.S. with low prices and fast shipping. However, even Amazon's rock-bottom prices cannot beat free. Here is how Amazon compares to library borrowing across different reading scenarios:

Scenario 1: Light Reader (1 book/month)

At Amazon's average paperback price of $13 with Prime, reading 12 books per year costs approximately $156 annually. A library card provides those same 12 books for $0 — a savings of $156. Not dramatic, but already free money.

Scenario 2: Average Reader (3 books/month)

Three books per month at $13 average (Amazon) = $468 per year. Library cost: $0. Annual savings: $468. Over 10 years: $4,680.

Scenario 3: Avid Reader (8 books/month)

Eight books per month at $13 average = $1,248 per year. Adding Kindle Unlimited ($144) for ebook convenience = $1,392. Library cost with Libby for ebooks: $0. Annual savings: $1,392. Over 10 years: $13,920.

Scenario 4: Family (parents + 2 school-age children)

Two adults at 4 books/month ($832/yr) + two children at 8 books/month ($1,248/yr) + audiobooks and ebooks = approximately $2,500+ annually at Amazon. Library cost: $0. Annual savings: $2,500+.

The Kindle/Libby trick: You can send borrowed Libby ebooks directly to your Kindle device. This means you get the Kindle reading experience — same device, same app — without paying for a single ebook. Just link your library card in the Libby app and send books to your Kindle email address.

When Buying a Book Makes More Sense Than Borrowing

The library is not always the right choice. There are legitimate reasons to buy books instead of borrowing:

  1. Books you will re-read or reference regularly. A recipe book, a coding reference, a self-help book you plan to work through multiple times — these justify ownership.
  2. Books you want to annotate heavily. If you are a student or researcher who marks up margins, writing in a borrowed book is not an option. Buy your own copy.
  3. Popular new releases with long waitlists. If a book has 200 holds at your library and you need it now, purchasing may be worth it rather than waiting months.
  4. Gifts. A beautifully wrapped book is a thoughtful gift. A library card borrow receipt is not.
  5. Supporting authors directly. Buying books, especially from independent bookstores, puts money directly in an author's pocket. Library borrowing does support authors through lending rights programs, but the per-borrow amount is smaller.
  6. Collector's editions or signed copies. Collectible books have investment value that borrowed copies cannot provide.
Hybrid strategy: Many avid readers use the library to "test" books before buying. Borrow first — if you love it enough to read again or recommend to others, buy it to own and support the author. This approach minimizes wasted purchases while still supporting the writing community.

The Environmental Case for Borrowing vs. Buying

The cost comparison is not only financial. Each new book requires paper, ink, energy, and transportation. A single library copy may be read by 50 to 100 people over its lifetime, dramatically reducing the environmental impact per reader compared to 50 to 100 individual purchases.

The environmental savings per library user are estimated at several pounds of paper and carbon emissions per year by the American Library Association. For heavy readers, the environmental benefit of library borrowing can be equivalent to reducing several car trips' worth of carbon emissions annually.

Frequently Asked Questions

Is the library always cheaper than buying books?
Yes, for any book you read once or rarely revisit, the library is cheaper — borrowing is free while even the cheapest used copy costs money. The only scenario where this might not hold is if your library charges a high non-resident fee and you only read 1 or 2 books per year. But for resident cardholders, the library is always the more economical choice for any amount of reading.
What is the average book price at Barnes & Noble vs. Amazon?
In 2025, Barnes & Noble hardcovers typically cost the full publisher's price ($29.99-$39.99). Amazon typically discounts new hardcovers 10-30% ($19.99-$27.99). Used Amazon copies can be $3-$12 plus shipping. The library remains the cheapest option at $0, regardless of format.
How long is the wait for popular books at the library?
Wait times vary dramatically. Older and backlist titles often have no wait at all. Extremely popular new releases (like a major celebrity memoir or blockbuster novel) can have hundreds of holds and wait times of 2-6 months at busy library systems. However, most libraries also purchase multiple copies of high-demand titles. If a wait is too long, you can request the title via interlibrary loan, which may be faster.
Can I use my library card to read books on my Kindle?
Yes. Through the Libby app, you can borrow ebooks from your library and send them directly to your Kindle device or Kindle app. The ebook appears in your Kindle library and disappears automatically at the end of the loan period — no fines, no returns required. This is arguably the most convenient way to read borrowed ebooks.
Does the library have new releases?
Yes. Most public libraries purchase new releases, including bestsellers, on or near publication day. Popular titles may have waitlists due to demand. You can place a hold on a book before it is released so you are first in queue. Many libraries also offer digital new releases through Libby with no physical waitlist constraints (though digital holds also exist for popular titles).
Does buying books support authors more than borrowing?
Per transaction, yes — an author earns royalties on each sold copy (typically 10-15% of the cover price, or $1.50-$4.50 per book). Library lending does compensate authors through programs like the Public Lending Right in some countries, but the per-borrow payment is smaller. However, libraries purchase their copies at full or near-full price, which generates the initial royalty. If supporting authors financially is your goal, buying from independent bookstores gives the most direct benefit.
Are used books cheaper than the library?
Used books can be very inexpensive — sometimes $1 to $5 at thrift stores or used bookshops. For books you want to own permanently, used purchases can be a great value. However, you still pay something, whereas library borrowing is free. Also, for recent or popular titles, used copies may not yet be available or may still be priced at $8-$15. The library wins on price for any book in its collection, though used books win when you want to own a title permanently for a low price.
