Bmr tdee help

Debx12345

ive read through a few old posts, but being a bit thick and need help.

My bmr is 1198, I have a body composition monitor which I put my activity as moderate, then it gave me my tdee as 1698. Now is tdee including exercise?

Mfp says I need to eat 1370 cals to lose 1/2 pound a week, and eat my exercise cals, which some days puts me at eating nearly 1500, this then puts me close my tdee which is what I understand as maintenance ( and includes exercise).

So starting to wonder if my lack o weight lose is due to me eating maintenance , hope you understanding what I'm getting at.
