How long will it take me to lose at least 3 % body fat?

Im around 155 and im 5 11 and im around 13% body fat . I play handball almost everyday and i play soccer almost every weekend. I just started to do some pushes ups around 30 in the morning and 30 at night and been lifting some weights. I also just started to take in a lot less calories around 1500 per day breaking it up in to 3 meals per day with 2 snacks. Im just curious on how long it will take me to lose that amount of body fat.
