A frequently asked question about this calculator is whether the final number is for maintenance, or whether a deficit needs to be applied to it. That question is understandable since people are generally not accustomed to finding out what the maintenance needs are of a given TARGET or GOAL bodyweight. So, the simple answer is, no, you do not need to apply a deficit to the final calculation, unless you want to apply the 10% “fudge factor.” If you have a weight loss goal, the calculations for your target bodyweight (which is lower than your current weight) have a deficit built into it. This is because in that case, you’re estimating the maintenance needs of a future bodyweight at a given level of physical activity. If you’re already at your target bodyweight, then simply plug in your current stats if you’re curious about what your theoretical caloric maintenance needs are.  

PS speaking of the theoretical, here’s something really important that online calculator pages fail to mention… All online calorie/macro calculators – including mine – are a way to make an educated guess. At best, calculators provide a starting point from which to adjust according to results. Another thing to note is that calorie calculators are mostly useful for folks who have had a haphazard intake, and have no clue what caloric intake maintains them. If you do have a solid grip on your current maintenance caloric requirement, then simply adjust your program up or down from this (known) baseline, and you can safely ignore the estimates that calculators spit out.
