I've found that 10-12 times your bodyweight in calories is about 'maintenance level'.
If you consider that we don't capture 100% of what we eat, or perhaps are off by some amount, I'd aim for 10x bodyweight, and weigh yourself three times a week. If you don't lose or gain, you've hit maintenance, which is a very important number to know.
Why? Because, dieting is a game of inches and ounces. If you know maintenance and can tweak some food (maybe a less fatty protein, or reducing some treat in half) you can take small steps which add up over time.
Trying to take big steps can be self-defeating.
