Calorie confusion

[Babyfaced Assassin]

I'm a bit confused about calories. Ok i see guides that you should multiply your weight by 12 for each lbs to get your base well i'm male 23 and 130lbs (i fight at a low weight class and dont intend to go up weight classes this year)
so 130 * 23 = 1560 calories
that seems ridiculously low especially since i train high intensity at least 12 hours a week
right now i would estimate im getting about 2500 calories, maintaining weight but i often feel weak
my estimate that some of my sessions burn over 1000 calories and yet i maintain my weight.
also protein, i've been recomended to eat 1g of protein per lbs of body weight so im at around 130grams, fine but then if i plug this into a ratio of what i'm following at the moment (40p. 30c. 30f)
it comes to 1300 calories!!!

ack
what's a good estimation?
should I eat more than 2500 calories or use it as a base and then eat more depending on my workout (by estimating how much i burn during the workout?) or should i be eating something else?
I keep my carbs to 30% because i seem to put on alot of weight if i eat too many carbs!

it's all so confusing!

I thought it was between 1.5 and 2 grams of protein per bodyweight.

Considering age, training frequency, and whether or not your diet is clean...I think you could cut eating closer to 2500 cals.

Your gonna have to weigh your self, eat 2500 cals per day for a week and see what happens, if your not losing, cut it back a couple hundred cals.
