i know how everyone puts 5f to 1m. without removing them. but what is the max he can be kept with? i have lots of space in a new cage i brought, also what if you did remove the females and just got them bred once every 2 months by him how many females could he breed each month? i'm looking for the max amount of females males can breed per age. like the max for 4 mths, 6mths, 8mths, etc.

well, of the 2 tanks I keep of rats.... I have mine as 1.1 and never remove the males. for MICE I have 1.3, 1.4 and 1.4 .... but since rats dont fight new partners like the mice do... I would assume he would breed as many as he could 
Thats about all I can help with but I know there are others on here who have many more rat colonies and I hope they can be of better help to you

What is your goal? Are you trying to impregnate as many females as possible or produce as many rats as possible? The two may not be one in the same.
I keep mine at 1.3 with the male in all the time. I have found this is what will produce the most rats possible. The problem comes when you have a male, 3 females, and 30 babies about ready to wean. This is the number your cage has to house. If you allow the babies to grow to 4 weeks like most do, then your females will be giving birth before you wean the first batch. Now you have one male, 3 females, 30 weaners, and 30 pups. That’s 64 rats in your cage. This is if you have a ratio of 1:3.
I have found that if you rotate the male between females, it is better for the female’s longevity, but they spend a lot of time with no babies and are therefore less productive. I have chosen to replace my female breeders more often in favor of producing more rats.
I think the male could probably keep 20 females fat and happy if that is your goal. It would take a rather large cage
