Security Review Fees (aka Listing Fees):
As of September 1 2013, the security review for new paid apps is $2,700 USD per app, up from the previous cost of $300 USD.
The annual review fee (aka "AppExchange listing fee") for paid apps remains $150 USD per app.
This change will not impact partners with free AppExchange apps (which I believe currently get free security review and free annual review).
Here's the blog post from Salesforce announcing the price increase:

AppExchange Partner models:
You may also be interested in looking at AppExchange Partner models (aka "ISVForce" and "Force.com Embedded").
http://www.salesforce.com/partners/isv/program-models/
The more common of these two is ISVForce. ISVForce is used to sell apps to people who are already Salesforce customers. Force.com Embedded is used to sell your app to people who are NOT Salesforce customers - these people get a version of Salesforce along with your app.
As of September 2013, paid apps in ISVForce pay 15% revenue to Salesforce. In return the primary benefits that you get are:
- Two (2) Enterprise Licenses for Salesforce to use for your company
- Use of the Salesforce License Management App (LMA). The LMA gives you a way to manage licensing of your app for your customers
- The opportunity to participate in paid advertising on the AppExchange
In addition two these two partner models, you can choose to use AppExchange Checkout.
If you choose to be an AppExchange Checkout partner, you will still pay a 15% revenue share plus a small per transaction fee. You will get the first two benefits above (2 licenses and use of the LMA). You will also get the ability to use AppExchange Checkout to automatically charge your customers credit cards for payment. This is a great option for low cost apps that are simple for customers to set-up on their own.
