Activity level?

When I first joined my activity level was sedentary and I was getting in maybe 3500 steps a day. I've now worked up to about 8800 to 9800 steps a day so would my activity level now be lightly active or moderately active?

My fitbit also says that i burn about 2300 calories a day but I'm not sure how to figure out the activity level from that because I don't want to choose the wrong one.
