The short version is, rates went up an average of 8.3% across all site types. I have updated my Fort Rate Calc spreadsheet to include 2018 pricing. It is available here (click me).
Obviously, the 2018 rates are included in the spreadsheet, so if you just want to see those they are in the Rate Lookup tab. Rates include 12.5% tax. This was the easiest way I could think to share the data, but if you'd like it in some other form, just let me know.
