An excellent calorie calculator, which estimates the amount of calories burned based on your body weight and activity is provided here:

You will be amazed on how many calories can an indoor rower burn!
This is also an excellent way to find out how much training you need to complete to get rid of unnecessary weight!
Notice that indoor rower is a great calorie-burner! Below I quote the results for my body characteristics inputting 3 indoor rowing sessions (note, that I normally execute separately each of those training sessions, but for illustration purposes I've added them together on a single day to outline their calorie expenditure).
Example - Basal Metabolic Rate Calculator(s) for a 105kg active person
The BMR for a 105 kg Male, 30-59 years old, is
2080.5 kcal.
Your energy expenditure for the day (excluding exercise) is your BMR (2080.5) multipled by your activity level (2.0)2080.5 x 2.0 =
4,161.0
Your hourly metabolic rate (HMR) is 2080.5 divided by 24.HMR = 2080.5/24 =
86.7
The
training cost in activity of each exercise is calculated as your HMR
multiplied by the Physical Activity Ratio of the exercise multiplied by
their time in hours. See the
Energy Costs page for a table of the different PARs for each pace.
ROWING SESSIONS considered:
Session 1 = 86.7 x 14.2 x (45/60) =
923 kcals (45min at 2:00/500m)
Session 1 = 86.7 x 21 x (8/60) =
243 kcals (8min at 1:45/500m)
Session 1 = 86.7 x 33.6 x (6/60) =
291 kcals (6min at 1:30/500m)
The total energy cost of your day is, therefore
5,618 (that is to say, your overall BMR plus all your exercise sessions).
Food Groups
The process outline here is a guide to your energy output and is a
good place to start if you are interested in weight management. The
other aspect is knowing the calorie balance. Energy is provided by three
food groups, carbohydrates, protein and fats. The relative balance
between these groups is 60% carbohydrates, 17% protein and 23% fats.
Carbohydrates and protein provide 4.3 calories per gram and fat provides
9 calories.
The dietary requirements for a daily output of 5,618 kcals
is therefore:
Carbohydrates = 5618.427 multiplied by (60/100) divided by 4.3 =
784.0 grams
Proteins = 5618.427 multiplied by (17/100) divided by 4.3 =
222.1 grams
Fats = 5618.427 multiplied by (23/100) divided by 9 =
143.6 grams
