I'm by far no expert on cutting, but I know there's a big variance between individuals due to body volume, metabolism, body type, amount of muscle mass, activities of daily living, exercise programming, etc. I'd try x amount of calories for two weeks and if you do not see results, change that to x-y.
Sorry I can't be more helpful but I tend to carry some extra fat and not worry about it too much as long as my lifts are improving.
