Congrats on your loss! I would suggest you read the "how many calories maintainers eat" thread at the top of this forum. It can help give you an idea of how many calories many maintainers eat, and the large range of calories maintainers eat. I think that to figure out their maintenance calories, many maintainers slowly added back calories to their daily intake, 100-200 per week or so, until their body told them they were "there".
I would caution paying attention to calories burn by exercise trackers like those on myfitnesspal, or on cardio machines, etc. I have found myfitnesspal GROSSLY innacurate, and if I ate all of the activity calories it tells me I've early, well, it wouldn't work. I just ignore that feature, too. Or the elliptical machine that tells me I burned 700 calories in an hour... yeah. No. (If you are really interested in figuring out how many calories you burn I believe a heart rate monitor with a band that really tracks your heart rate is much more accurate.) And stick around! We love new maintainers.
