Esker net revenue so far

I'm going to add a graph here for folks interested in the business of self-publishing a game. I'll update this over the next year or so as the project continues.

The graph here shows all my expenses to date (all the stuff below zero) and all my net revenue from sales (the stuff above zero). The sales income already has the fees deducted (for sales on my site, that's credit card processing and shipping; for sales on Amazon, that's their fees). I'll break even when the stuff above the line matches the stuff below the line.

Note that the dates here aren't evenly spaced, so while time advances to the right, its speed isn't even. The net revenue (income minus expenses) figure now is -$3,109, so I have a lot of ground to cover to break even. Here's a representation of that.

At my current price of $14.99, which is the same on my site and on Amazon, I net the following:

PlanktonGames.com: about $10.99
Amazon.com: $9.54

In both places, the shipping is free to customers, meaning that I pay for it. Initially, I was going to charge shipping on my site, but I changed it once I learned that even non-Prime Amazon sales had shipping included when you do fulfillment by Amazon. I thought (a) people might resent the extra shipping charge, since folks are getting used to free shipping, and (b) it was nice to have the same price on my site and Amazon.

At those prices, I'll need to sell a bit more than 300 more games to break even, although I'll obviously incur more expenses as I go if I continue to do advertising, send out review copies, and run into other stuff such as NC sales tax.
