Every book I know of makes the rollover based on deposit plus bonus. So if you have a 50% bonus up to $500 with a 5x rollover and deposit $1000; you'll get $500 in bonus money = $1500 starting balance. Multiply the starting balance by 5 gives you $7500 which is how much you must bet before you can withdraw.
Another thing to keep in mind- They also count towards the rollover requirement the lesser of your bet amount or your profit if you were to win the bet. So if you bet $110 at -110 to profit $100 using standard vig, only $100 will count towards the rollover. Likewise, if you bet $100 at +500 to profit $500, you'll only get $100 credited towards the rollover. This is to prevent people from betting super high chalk to meet the rollover (or at least make it more difficult).
