Way too many variables for even a vague idea my man. In this area, dieting, everyone is unique. First of all you provided no stats or training methodology. That has a lot to do with caloric needs. There is no way to determine this other than through experimentation on your part. It takes time and patience to learn what it takes to trigger fat loss in your body while at the same time maintaining your lean body mass. Everybody's needs are drastically diferent. When I begin my diet(in several months) I will be 280. The first four weeks I will gradually ease into restricted calories by slowly omiting various foods and thus gradually dropping calories. This process won't actually be part of the diet, but it will prime my body for restricted cals so I can maintain my muscle mass. After the first four week phase I will be at 3000 calories per day. 420g protein, 200g carbs, 30g fat. No cardio until the last six weeks or so...until absolutely needed. I have a hard time preserving muscle mass so I don't even look at a treadmill. I rely soley on diet for as long as I can to induce the fat loss. On Sundays I have a high calorie day during the all out dieting phase. This day is 5000 cals and it is to re-stoke my metabolism and replenish my muscles with desparatly needed glycogen. I will stick with this for as long as it's working. If I'm dropping weight too fast I will add in carbs to slow the process and keep the muscles full. When fat loss halts instead of cutting calories or adding mindless hours of muscle wasting cardio I will take two weeks and eat 5000 cals a day. This will upregulate my metabolism as that is the source of the ceased weight loss. Then I will go back on the diet. The final step will be to cut another 200 calories the final four weeks to get the last ounces of fat burned off. The total process for me takes 20 weeks. It took me a while to figure this out. Lots of experimenting and learning. I learn something new every time I diet so It's aqnever ending quest for perfection. Like I said though, no two body's are the same. This one's up to you to figure out.
