best diet to maintain body weight?

[BiggerisBetter]

My stats:
20 years old, 240, 6'4", 10pbf

I currently just want to maintain my body weight and want some advice on what route i should take.
First off, i am thinking i should consume about 3500 cal (240*15)?
Is this about right or should i multiply my bodyweight by 12 instead?
Second i am thinking i am going to do the isocaloric split (33, 33, 33)
What are your thoughts on this?
Also i weight train 5 days a week, and 3 days of light cardio post workout (30min on treadmill, 3mph 8%incline)
I am looking for any suggestions, i just want to maintain my muscle mass and not increasing by body fat

come on bros, no one can tell me which way of maintaining worked best for you
for the past year and a half i've either been bulking or cutting, so i'm not really used to maintaining
i'm happy where i'm at...at least until i start my next cycle lol

Your calorie level looks right on. You'll just have to try it out and see if you're maintaining your weight. If not make the necessary adkustments to calories. Everything looks fine here in written words, but the actual outcome can only be determoned with experimentation. It looks to be a solid foundation to start with and you have a plan to work with. Weigh in once a week and see how the scale is moving, or in your case hopefully not moving.
