Publisher Breakeven Formula
The breakeven formula for a publisher finds the total number of book copies (Q) that must be sold for a specific title to cover all its fixed and variable costs.
Q = F / (P – V)
Solve for Total Fixed Costs (F):
F = Q * (P – V)
Solve for Net Revenue per Book (P):
P = (F / Q) + V
Solve for Variable Cost per Book (V):
V = P – (F / Q)
Variables Explained
- Total Fixed Costs (F): The total *upfront* investment to create the book, before any copies are sold. This includes the author’s advance, editing, cover design, interior layout, and marketing.
- Net Revenue per Book (P): The *actual amount* the publisher receives for one copy. This is the cover price *minus* the retailer/distributor discount.
- Variable Cost per Book (V): The direct cost of one copy. This is primarily the printing cost, but also includes the author’s royalty (if paid per copy) and shipping/fulfillment costs.
- Breakeven Units Sold (Q): The total number of copies the publisher needs to sell to earn back their initial investment.

What is a Publisher’s Breakeven Point?
A **Publisher’s Breakeven Point** is the most important number for a single book title. It represents the exact number of copies (Q) that must be sold to completely recoup the publisher’s initial, one-time investment. Until this number is reached, the book is “in the red” (unprofitable). Every copy sold *after* the breakeven point generates pure profit.
**Fixed Costs (F)**, also known as “plant costs” in publishing, are all the expenses incurred *before* the book is printed. The largest is often the **author’s advance**. This also includes professional editing, cover design, typesetting/interior layout, proofreading, and any initial marketing budget (e.g., sending review copies).
**Net Revenue (P)** is *not* the cover price. If a book’s cover price is $25, a bookstore buys it at a 50% discount ($12.50). This $12.50 is the publisher’s net revenue, or (P). **Variable Costs (V)** are the costs to produce that single copy, primarily the printing cost (e.g., $2.50) and the author’s royalty (e.g., 8% of the cover price, or $2.00). In this case, V = $4.50.
The **Contribution Margin** (P – V) is the profit from a single book sale that goes toward paying back the fixed costs. In our example, `$12.50 (P) – $4.50 (V) = $8.00`. This calculator finds how many $8.00 “profit chunks” are needed to cover the total (F).
How to Calculate Publisher Breakeven (Example)
Let’s calculate the breakeven point for a new hardcover title.
-
Identify Total Fixed Costs (F):
The publisher pays a $10,000 author advance, $5,000 for editing, $3,000 for cover/interior design, and $2,000 for marketing. Total (F) = $20,000.
-
Identify Net Revenue per Book (P):
The book’s cover price is $28. The average retailer discount is 55%, so the publisher’s net revenue (P) is $12.60 ($28 * 0.45).
-
Identify Variable Cost per Book (V):
The printing cost is $3.00 per book. The author’s royalty is 10% of the *net revenue* ($1.26). Total (V) = $4.26.
-
Apply the Formula: Q = F / (P – V)
First, calculate the contribution margin per book: $12.60 (P) – $4.26 (V) = $8.34.
Next, divide the fixed costs by this margin:
Q = $20,000 / $8.34 = 2,398.08 -
Conclusion:
The publisher must sell 2,399 copies (rounding up) to cover their entire $20,000 investment. The 2,400th copy sold will be the first one that generates actual profit.
Frequently Asked Questions (FAQ)
You should calculate a separate breakeven for each format, as the (P) and (V) are completely different. For an ebook, (V) is very low (just the author’s royalty and a small transaction fee). This means the breakeven quantity (Q) is often much lower.
You can use this calculator in reverse. Decide on a realistic sales goal (Q) for the first year (e.g., 5,000 copies). Enter your (P) and (V). Then solve for (F). This tells you the *maximum* fixed cost (including the advance) you can afford while still breaking even at 5,000 copies.
The author’s royalty is a **Variable Cost (V)** *if* it is paid as a percentage of each sale. The author’s **advance** is a **Fixed Cost (F)**. The royalties earned on each sale are first used to pay *back* the advance; the author doesn’t receive additional royalty checks until the advance has “earned out.”
This is the most important part of publishing finance. Retailers (like Amazon or Barnes & Noble) and distributors take a large percentage (40-55%) of the cover price. The publisher’s revenue (P) is only what’s left over *after* those discounts.
