Calories Calculation

Im finding problems in calculating my total calories. Im 24, 167lb, ecto, have a light day, and 40 min. hard full body train 2x week.

At first, I`ve found BMR: 1850 cal
Added 50%: 925 cal
And 300 cal due to iron train.

So, eating 300 over, I came to:
Train days: 3075 + 300 = 3375 cal
Off days: 2775 + 300 = 3075 cal

Is that right?
Sorry for my English!
Thanks

The math is right from reading on here ive realized that only you can really only decide if your eating enough, if you have enough energy to have a good workout and see results than I guess so
