Hello folks. Can someone estimate what my caloric requirement is, I am:

43 years old
175 lbs
About 18% BF (very approx)
Doing weights a couple of times a week
Doing sprints once/twice a week.
Prob eat <50g carbs a day. Though do a bit of wine.
Sitting on my arse the rest of the time.

I want to experiment eating up to a certain amount of calories and seeing what happens to my fat levels.

Thanks if you can help.
