Your e‑book break-even price is the minimum retail price you need to charge so that your royalties cover your upfront publishing costs (editing, design, formatting, marketing, etc.) plus any profit you want to earn. This calculator is designed for self‑published authors and small presses who sell primarily through major digital platforms.
Instead of guessing whether $2.99, $4.99, or $9.99 is “right,” you can enter your real numbers and see the minimum price that recoups your investment at your expected sales volume and platform fee.
The calculator focuses on four key inputs that match the form labels above:
The general formula used is:
Break-even price = (Upfront production costs + Desired profit) / (Expected copies × (1 − Platform fee% / 100))
In math notation, if we call costs C, desired profit P, expected copies N, and platform fee percentage f, then the price per copy p is:
This calculation assumes a constant royalty percentage across all sales and ignores taxes and refunds (see Assumptions & Limitations below).
Enter your Upfront Production Costs ($). Sum everything you do not pay per copy, such as:
Set the Platform Fee (%). This is the retailer’s cut. For many e‑book platforms:
Type the percentage as a whole number, for example enter 30 for a 30% fee.
Estimate your Expected Copies Sold. Use your genre, mailing list, and marketing plan to make a realistic guess. Debut authors often choose a conservative figure; more established authors might use past launch data.
Add your Desired Profit ($) if you want to earn more than break-even. Leave this at 0 if you only want to recover your costs, or enter a target profit (for example, $1,000) to see what price would cover both costs and that profit.
Click “Calculate Price.” The tool computes the minimum price per copy that lets you reach your goal at your specified sales volume and fee.
Review and adjust. Once you see the result, you can test different scenarios: lower or higher sales, different platform fees, or alternative profit goals, and see how the recommended minimum price changes.
Imagine the following situation, similar to the default values in the form:
First, calculate your total revenue target:
Total needed = Upfront production costs + Desired profit = 3,000 + 0 = $3,000
Next, find your net revenue per copy. With a 30% platform fee, your royalty rate is 70%, or 0.70 of the retail price:
Net per copy = Price × (1 − 30 / 100) = Price × 0.70
Now plug everything into the formula:
Break-even price = 3,000 / (1,000 × 0.70) = 3,000 / 700 ≈ $4.29
You would need to price your e‑book at roughly $4.29 just to recover your $3,000 investment if you sell exactly 1,000 copies.
If you also want a $1,000 profit on top of those costs, the total needed becomes $4,000:
Break-even price with profit = 4,000 / (1,000 × 0.70) = 4,000 / 700 ≈ $5.71
In practice, you might round these figures to market-friendly price points such as $4.99 or $5.99 and then re‑run the numbers to see the implied profit at those prices.
The calculator shows you the minimum sustainable price based on your assumptions. You can think of the output as a decision support tool rather than an exact prediction:
Use the estimate alongside your knowledge of genre norms and reader expectations to choose a final retail price.
The table below compares a few common pricing scenarios for illustration. These are not recommendations, but they show how the same project looks under different strategy choices.
| Scenario | Upfront Production Costs | Platform Fee | Expected Copies Sold | Desired Profit | Approx. Break-Even Price |
|---|---|---|---|---|---|
| Budget launch in a popular genre | $1,500 | 30% | 1,500 | $0 | ≈ $1.43 |
| Standard indie launch (similar to defaults) | $3,000 | 30% | 1,000 | $1,000 | ≈ $5.71 |
| High-production niche nonfiction | $6,000 | 35% | 800 | $2,000 | ≈ $15.38 |
Your own numbers may differ significantly. The key insight is that higher fees, lower sales, and higher production budgets all push your minimum viable price upward.
This e‑book break-even pricing calculator is an educational estimation tool. It simplifies real‑world publishing in several ways:
Because of these simplifications, the results should not be treated as financial, legal, or tax advice. They are best used as a planning aid to understand how changes in costs, fees, and sales volume affect your minimum sustainable e‑book price.
