25,000 in debt at 23, $900 a month, How many years will it take to be debt free?

My student loans and relocation bonus from an old job total $25,000 in debt. Currently, I just started a job that pays 60,000 a year. I have about $900 left over each month before groceries but after all my bills. Anyone who was in a similar situation, how long did it take to save/make more money? How long did it take to pay off your debts and what were the amounts?
