Calorie goal seems absurdly high

You're trying to put on mass AND are active, so it makes sense. Just eat more calorie dense stuff.

After you hit your protein macro, if you need some fats, unrefined coconut oil is sooo good. Peanut butter. Any kind of nuts or nut butter. Avocados.

And then there are the delicious, delicious carbs. Anyone here who can't eat 500 calories of bread? I doubt it.

It sounds about right.

If 2000 Cals per day is difficult, then it also sounds like ice cream just became your new best friend.

Recently, I have been trying to put on more muscle mass to help with sport/general health as I am a little underweight (50kg at 165cm; 110lb at 5"5'). I have an active lifestyle (I honestly can't remember the last time I had a day without exercising) but apparently my resting calorie need is around 2300, so when I factor in my olympic lifting and cycling it can sometimes be has high as 3200! This seems ridiculous, I can just about manage to reach 2000 let alone 3000! Do I really need to eat this much?

Putting on muscle means adding mass. Adding mass has to come from somewhere. It just doesn't magically appear when one works out.
You should be happy. You get to eat more food.

My currently weight loss caloric intake is 2500ish calories, and it's going to increase as I get more active over the summer.

Eating 3000+ to put on mass? That sounds about right.

My goal weight maintenance is going to be around 2800 calories so yours isn't surprising at all.
My goal is 6'2 200 pounds and lightly active.

I don't question this. I've had the goal number on biking days come up past 2800... -after- taking out for intended weight loss. This is what happens when you rack up a lot of exercise, and if you're ramping up the workouts on top of it the numbers will only get crazier. Yes, eat them all.

at 110lbs there is no way your resting calories are 2300. I weigh 145 and my maintenance without exercise in he the 2000 cal range, I thing the 2300 is either a surplus, or includes your exercise.

go to goal, look at calories burned from normal daily activity. that is maintenance with no exercise, so you would have to eat more than that plus exercise calories to gain weight.

that's a lot of chicken and rice.
<< jealous!

Don't rely on MFP's calculations for this stuff as they are generally geared in the national generic public range of these things and is not reflective in my experience of people who are very active.
What you need to do is get someone to measure your fat percentage using calipers or some other physical method; your gym should have suggestions; (not online tools that are more worthless than farting in the wind) and that together with your weight, I can accurately calculate your BMR (Basal Metabolic Rate - the calories you would burn if you laid in bed all day). This is your starting point for weight loss/maintenance/gain.

The more you workout each day, the more calories you burn on top of your BMR. PM me if you want some help on figuring out your BMR and how much you should eat to gain.

The only way to know for sure is to give it a try. MFP originally told me maintenance was somewhere around 2300 a day. I'm tall (5'10 female) and very active (runner, lifter, casual soccer player), but this amount would have caused my weight to skyrocket. There's no way a computer can know your metabolism exactly as it is.
