Am I doing this right?

I'd like to make sure im doing this right before I start eating more calories than I should be or not eating enough. My BMR is 1538 according to MFP calculator. I multiplied it with 1.2 for sededary which makes it 1845.6. SO I set my net calorie goal as 1845 right? Then I eat the 1538 leaving me with a deficit of 307. If I want to lose 2lbs a week I have to exercise & burn 693 calories right so my net ends up 1000 right? Thanks!
