Most of the materials I use are found on the internet for free.
Generally speaking, we calculate the amount of time while learning is boring.
As for time spent every day, I try to do something in my target languages for least one hour every day.
I wish I spent 2-3 hours for my foreign languages.
But actually I spend for all my languages about one hour a day.
It's maybe good for one language, but for 4 languages it's too little.
But as a teacher I know that it's better 15 minutes on daily basis that 2 hours once a week.
