Applying Accounting Concepts to an Author’s World by D. F. Hart, MBA

Today we welcome a new guest writer to Writer’s Fun Zone, D. F. Hart who is stopping by to chat with us about “Applying Accounting Concepts to an Author’s World.” Enjoy!


As an accountant, I get asked a lot of questions from fellow authors once they realize that my ‘day job’ and background deals heavily with numbers. 

Below are two common questions I’ve fielded over time. Hopefully, at least one answer here can help you on your author journey.

Q. What types of data should I be tracking? 

A. While you want to track production costs (cover design, editing, proofreading, formatting, etc.) you also need to keep track of your overhead costs (website build/domain, newsletter list builds, any money you spent to set up your business structure, etc.). 

I call these things ‘the costs of doing business‘. The things that you’re going to spend money for, regardless of how many books you publish and sell, even if you don’t publish and sell any. 

You’re also going to want to allocate that overhead against your books. 

By “allocate” I mean, make each title ‘carry its fair share’ of the overhead cost by portioning out that expense across your revenue streams. If you like, you can take each title’s portion and split it out even further against each of that title’s formats. Such as applying a portion of expense against Z title’s eBook, paperback, large print, and audiobook. 

As your number of titles and formats increases, the ‘overhead’ costs assigned to each will go down.

The Allocation Example

I spend $300 per year for my website, and I currently have sixteen titles out on the market.

$300 / 16 = $18.75 per title

Let’s say for each title, I offer them in eBook, paperback, and large print. So, I could take that $18.75 per title, and put one-third toward each format of each title:

$18.75 / 3 formats = $6.25 per title’s format

In other words, each of my 16 eBooks would be responsible for helping me recoup $6.25 of my annual website costs.

Then, when you run a break-even calculation, you can be more comfortable knowing that once that title (or title’s format, if you broke it down to format level) reaches that # of units sold, it’s operating in the black (absent any recurring ad spend specifically for that title, that is).

Q. What’s a good way to help me decide how to spend my budget dollars? Where should my focus be?

A. I believe first and foremost in running a break-even point calculation for every revenue stream that I do or am considering. 

Once I know the number of sales past which something would become profitable for me, then I compare results to help me decide where best to focus my budget dollars – and my time. 

The break-even formula

Break-Even Units = Total Fixed Costs / (Sales Price per Unit – Variable Cost per Unit). 

Or in plain language:

How many units I need to sell = My total costs to produce / My net royalty per sale

For example, I have book one of my thriller series out in eBook, paperback, large print, and audio formats. 

I know the break-even ‘magic number’ for each one and I can tell you that by far, eBook is the best performing with regards to how quickly it surpassed its break-even point (no big surprise). But large print’s second place ranking did surprise me, as did audio coming in dead last. 

Those trends tell me that right now, I’m better off not worrying so much about audio for other books in that series just yet. 

In addition to different formats, some authors also have things like merchandising in place. And once again, break-even point calculation is a good place to start. 


A custom-designed pin costs you $500 for a set of 100, and you sell each pin for $7. You’d only have to sell 72 of them to recoup your $500. (Formula: X units = $500/$7, or, X=72). The other 28 out of the 100 you bought would be 100% profit for you when they do sell.

But you also need to ask yourself: what is the demand for that pin versus a custom bookmark, or mouse pad – or hardcover, or translation, or audiobook? 

And that’s going to vary from audience to audience. 

Acctg for Authors CoverScented candles might work well for a romance audience. 

Urban fantasy? Maybe not so much. Hardcover formats might be a better investment.

So, learning your genre’s fan base matters just as much as knowing your break-even numbers.
