Maintenance in your case is most likely somewhere around 12-13
calories per
pound of bodyweight, assuming exercise.
That said, you would cut 35% or so from there and see how things progress.
Keep it simple.
And remember, you're not signing any contracts here. If the first intake you pick isn't working (either losing too fast or too slow) you simply readjust accordingly. That's why it's silly to spend a ton of time on figuring out a starting point. All these calculations are mere estimates and regardless of how fancy the formula, you're going to have to play 'this game' of adjusting based on bodily feedback.
