Imagine Making $9,000 A Day From Something You Did 50 Years Ago… That's What Harper Lee Did With "To Kill a Mockingbird"

In December 1956, Harper Lee was 30 years old, living in New York City and working at an airline reservation desk. She wanted to become a writer, but after a full day at a job she disliked, there was only so much time and energy left for fiction.

Then, on Christmas morning, Lee found an envelope hanging from a tree at the home of her friends Michael and Joy Brown. Inside was a note:

"You have one year off from your job to write whatever you please. Merry Christmas."

The Browns had enjoyed a good year financially and offered to cover Lee's living expenses for the next 12 months. Their gift allowed her to leave her job, concentrate entirely on writing and complete the manuscript that eventually became one of the most successful novels of all time.

More than half a century later, court documents would reveal just how valuable that Christmas present had become.

During one six-month period in 2009, Harper Lee earned exactly $1,688,064.68.

That's equal to $9,250 in royalties every day. From a book she had completed roughly 50 years earlier.

Before "To Kill a Mockingbird"

Nelle Harper Lee was born on April 28, 1926, in Monroeville, Alabama. Her father, Amasa Coleman Lee, was an attorney, newspaper editor and member of the Alabama legislature. Elements of his legal career and personality later helped inspire Atticus Finch.

Lee grew up near Truman Capote, who became one of her closest childhood friends. Capote later provided some of the inspiration for Dill in "To Kill a Mockingbird," while Lee helped him conduct research for his true-crime masterpiece, "In Cold Blood."

Lee attended Huntingdon College for one year before transferring to the University of Alabama. She studied law but left six months before completing her degree, having decided that she wanted to write rather than practice law.

She moved to New York in 1949 and worked as a reservation clerk for Eastern Air Lines and British Overseas Airways. Outside of work, she wrote short stories and submitted them to publishers.

Literary agent Maurice Crain saw promise in her work and encouraged her to continue. Lee also became close with Broadway composer and lyricist Michael Brown and his wife, Joy. It was the Browns who ultimately gave her the extraordinary Christmas gift that changed her life.

The Yearlong Gift

Imagine receiving a check covering an entire year of your salary, with one condition: You must spend those 12 months completing the passion project you otherwise never have time to pursue.

Would you record an album? Start a company? Make a film? Launch a website?

Harper Lee used her year to write.

The manuscript she produced was originally called "Go Set a Watchman." It followed an adult Jean Louise "Scout" Finch returning to her Alabama hometown and confronting the views of her aging father, Atticus.

Lee submitted the manuscript to J.B. Lippincott & Co. Editor Tay Hohoff saw talent in the young writer but believed the novel needed substantial work. She was particularly interested in the childhood flashbacks and encouraged Lee to rewrite the book from the perspective of Scout as a young girl.

Lee spent more than two years revising the manuscript. At one stage, it was called "Atticus." Eventually, the story evolved into "To Kill a Mockingbird."

It was not merely a matter of changing the title. Characters, structure, tone and perspective were extensively reworked through multiple drafts. The final novel became a very different book from "Go Set a Watchman."

An Instant Classic

"To Kill a Mockingbird" was published on July 11, 1960. Lee's editors had warned her that the novel might sell only a few thousand copies.

Instead, it became an immediate sensation.

The book won the 1961 Pulitzer Prize for Fiction and was quickly translated for international readers. Its story of Scout and Jem Finch, their fascination with the mysterious Boo Radley, and their father's defense of a Black man falsely accused of raping a white woman became one of the most widely read narratives in American literature.

"To Kill a Mockingbird" has sold more than 40 million copies worldwide and has been translated into more than 40 languages. It has remained a fixture in classrooms, libraries and bookstores for generations.

In 1962, the novel was adapted into a film starring Gregory Peck as Atticus Finch and featuring Robert Duvall in his film debut as Boo Radley. The movie received eight Academy Award nominations and won three, including Best Actor for Peck and Best Adapted Screenplay.

Legal Dispute Exposes Royaties

Most books enjoy their strongest sales immediately after publication and then gradually disappear. "To Kill a Mockingbird" did the opposite: It became an enduring institution.

Decades after its release, the book was still selling hundreds of thousands, and during some years, more than one million copies annually. Every new school year introduced the novel to another generation of students.

For many years, the exact size of Lee's royalty income remained private. That changed during a legal dispute with Samuel Pinkus, the son-in-law of her longtime literary agent.

Lee accused Pinkus of taking advantage of her declining health and persuading her to assign him the copyright to "To Kill a Mockingbird." Court filings associated with the dispute offered an unusually detailed glimpse into the book's finances.

The documents showed that Lee received $1,688,064.68 in royalties during the six months ending in December 2009.

Doubling that amount produces annual income of $3,376,129.

Divided across 365 days, that works out to $9,250 per day.

That figure should be understood as an annualized snapshot of one particular royalty period, not a guaranteed daily payment that remained identical every year. Book sales, royalty rates and licensing income naturally fluctuate.

But the larger point remains remarkable. Nearly 50 years after completing "To Kill a Mockingbird," Harper Lee was still earning millions of dollars annually from it without publishing another conventional novel.

The Price of Success

Lee did not enjoy the attention that came with literary fame. After giving interviews and making appearances during the years immediately following publication, she largely withdrew from public life.

By 1964, she had stopped discussing herself with the press. She divided her time between New York and Monroeville and became famous for guarding her privacy.

Lee attempted other projects, including a second novel and a nonfiction book about an Alabama murder case, but neither was completed to her satisfaction.

Her reluctance to publish again was often described as a case of writer's block, but Lee suggested that publicity was part of the problem. The success of "To Kill a Mockingbird" had given her financial freedom while also subjecting her to a level of scrutiny she never wanted to experience again.

Lee made a rare public appearance in 2007 when President George W. Bush awarded her the Presidential Medal of Freedom.

"Go Set a Watchman"

For decades, Harper Lee was known as the author of a single published book.

That changed in 2015 with the publication of "Go Set a Watchman."

The book was initially promoted as a newly discovered sequel to "To Kill a Mockingbird," but it was actually the earlier manuscript Lee had submitted before rewriting the story under Tay Hohoff's guidance.

Its publication became controversial. Lee was 89, had suffered a stroke and experienced problems with her eyesight, hearing and memory. Friends and commentators questioned whether she had knowingly approved the book's release, although representatives for Lee maintained that she had.

"Go Set a Watchman" also shocked readers with its depiction of an older Atticus Finch holding racist views. The contrast demonstrated just how dramatically Lee and Hohoff had transformed the original manuscript while creating "To Kill a Mockingbird."

Lee died in her sleep in Monroeville on February 19, 2016, at the age of 89.

A Literary Estate That Keeps Earning

Lee never married and had no children. Control of her copyrights and unpublished writings passed through her estate and trust.

The financial value of those rights extends far beyond ordinary book sales. The estate can earn money from hardcover and paperback editions, digital books, audiobooks, foreign translations, educational editions, theatrical productions, film licensing and merchandise.

Because "To Kill a Mockingbird" was published in 1960 and its copyright was renewed, it is expected to remain protected in the United States through the end of 2055. That gives the estate decades to continue collecting income before the novel enters the public domain.

And the estate has found new material to publish.

In October 2025, HarperCollins released "The Land of Sweet Forever," a posthumous collection featuring eight previously unpublished short stories and eight pieces of nonfiction. The stories were written during Lee's early years in New York and Alabama, before the publication of "To Kill a Mockingbird."

Nearly a decade after her death—and almost 70 years after her friends gave her the freedom to spend a year writing—Harper Lee's work was still generating new books and new revenue.

Who Receives Harper Lee's Royalties Today?

Harper Lee never married and had no children. Under the estate plan she left behind, most of her assets—including the rights to "To Kill a Mockingbird" and her other writings—were transferred to the Mockingbird Trust, a private trust she created in 2011.

Court records identified Lee's closest surviving relatives, a niece and three nephews, as beneficiaries entitled to undisclosed portions of the estate. Her attorney, Tonja Carter, was named executor and given broad authority to manage Lee's literary properties, although Carter's role as manager does not necessarily make her the ultimate recipient of the royalties.

Today, payments from book sales, theatrical productions, adaptations, foreign editions, and other licensing agreements flow to the Mockingbird Trust. Because the trust agreement is private, the precise beneficiaries, distribution percentages, and amounts paid to individual family members have never been publicly revealed.

Postscript: Sting + "Every Breath You Take"

When we first published this article back in 2013, we compared Lee's income with the royalties earned by Sting from "Every Breath You Take."

Sting wrote the Police hit and received the song's primary songwriting credit, leaving his bandmates without a share of its publishing royalties. The song became even more lucrative after Puff Daddy sampled it extensively for his 1997 hit "I'll Be Missing You." For years, Sting was said to earn approximately $2,000 per day in royalties from "Every Breath You Take."

That is an extraordinary financial achievement. But during the royalty period exposed in Harper Lee's court records, "To Kill a Mockingbird" was producing more than four times that amount.
