I will say that this guide is very good, but it does bit miscalculate a bit on the price of LJ. It only calculates if you do 12 month at a time purchase (something that not a lot of RPers do due to uncertainty of if we'll keep a char a full year.)

The actual prices are:

WITH AUTO PAYMENTS
Basic Paid Account + 1 Icon Package (same icon number as basic paid DW account, 100 icons)
1 Month Increments = $4 per month = $48 a year
2 Months Increment = $7 every 2 months = $42 a year
6 Months Increments = $21 every 6 months = $42 a year
1 Year Increments = $29.95 every year = $29.95 a year

Paid Account + 3 Icon Packages (10 icons less than Dreamwidth Premium)
1 Month Increments = $6 per month = $72 a year
2 Months Increment = $11 every 2 months = $66 a year
6 Months Increments = $33 every 6 months = $66 a year
1 Year Increments = $49.95 every year = $49.95 a year


WITH MANUAL PAYMENTS
Basic Account + One icon package
2 Months Increments = $7 every 2 months = $42 a year
6 Months Increments = $21 every 6 months = $42 a year
1 Year Increment = $35 per year = $35 a year

Paid Account + 3 Icon Packages (10 icons less than Dreamwidth Premium)
2 Months Increment = $11 every 2 months = $66 a year
6 Months Increments = $33 every 6 months = $66 a year
1 Year Increments = $55 every year = $55 a year

So...yeah.
