Rowing Machine Calories Burned Calculator

Calories burned on a rowing machine is the energy your body uses to drive the handle, slide back up, and keep going stroke after stroke. It depends mostly on your weight, how long you row, and how much power you put out.

What Rowing Machine Calorie Estimates Measure

The total covers every calorie you use on the rower, including what your body would burn at rest anyway, so it is a gross figure. Your heart rate and technique are not part of it. If you want your split, pace or finish times, use the Rowing Pace Calculator instead.

The Formula

Calories (kcal) = MET x body weight (kg) x time (hours)

1 MET = about 1 kcal per kg of body weight per hour

A MET compares rowing, or any activity, with sitting at rest. Rowing machine values are taken straight from a long list of energy costs for adults aged 19 to 59: the 2024 Adult Compendium of Physical Activities¹.

How This Calculator Computes Your Result

Start with your age group, your weight in pounds or kilograms and your rowing time. Then choose an effort, or type the average watts from your monitor and the tool picks the matching compendium band (the six options are in the table below). If you only know your split, the Rowing Pace Calculator turns it into watts.

Pounds become kilograms, the rowing MET is looked up, and the three numbers are multiplied. Rounding is to the nearest 5 kcal, and the MET is displayed to one decimal. The watt bands are wide, so the result jumps at 100, 150 and 200 watts. Next to your total, the tool lists calories per hour and per 30 minutes, and a table of all six rowing options at your weight. In watts mode you also see what a Concept2 monitor would show. Rowers under 18 get no result, because energy values for young people differ. At 60 and over you see a note that older adults may burn less.

Split my workout (optional). Interval sessions such as 8 x 500 m include rest between pieces. Enter your rowing minutes (counted) and rest minutes (left out), and the result is labeled "active time only".

What Your Result Means

Read the number as the energy that row used, not as a target. On the rowing machine, a 70 kg (154 lb) adult burns:

Most gym rowers doing a steady session sit in the first three rows. The top rows are hard efforts that few people hold for an hour. A heavier rower gets a higher estimate at the same effort.

Why Your Monitor Shows a Different Number

Concept2 monitors use this formula²:

Calories per hour = (4 x average watts / 1.1639) + 300

Dividing by 1.1639 turns watts into Calories per hour (one watt is about 0.86 kcal per hour), so you may also see it written as watts x 4 x 0.8604 + 300, with almost the same result. Multiplying by 4 means the formula assumes about a quarter of the energy you burn reaches the handle. The 300 is a fixed base rate that Concept2 sets for a 175 lb (79.4 kg) person, well above a true resting burn of about 80 kcal per hour, so your weight is not part of the monitor's number² ³.

This calculator starts from your weight and uses broad watt bands instead, so the two numbers drift apart:

Calories for 60 minutes of rowing¹ ². At easy and moderate watts, the monitor shows more than this calculator for most people. Concept2's own Calorie Calculator swaps the fixed 300 for a value based on your weight³.

Which is closer? Neither is exact. In 43 overweight and obese adults new to rowing, the monitor overestimated measured energy use by about 2.3 to 2.9 kcal per minute, roughly 140 to 175 kcal per hour⁴. The authors pointed to the monitor's general formula as a likely cause⁴.

What Changes Your Burn on the Rower

Power, not stroke count. The flywheel measures how much work you put in. Rowing more strokes per minute with a weak pull does not raise your watts, so use average watts when you have them.

A seated, non weight-bearing machine. In 30 recreationally active men, a Concept2 RowErg used about 11.5 kcal per minute at a hard effort (RPE 17), compared with 12.5 on a spin bike, 12.8 on an elliptical, and 15.2 on a treadmill at the same effort rating⁵. The authors explained this by rowing not being weight-bearing and by the lighter work in the recovery part of each stroke⁵. That 11.5 kcal per minute is about 690 kcal per hour for men averaging 73 kg.

Machine type. On Concept2's dynamic model, collegiate men used 5.1% more oxygen at the same race power than on the standard model⁶.

Skill and steady pacing. Rowing is a learned skill⁴, and a session with fast bursts and long easy stretches can average out to modest watts. Interval rest should go in the split helper, not the rowing time.

Rowing Machine Compared With Other Activities

Here is how the rowing machine stacks up over 60 minutes (2024 Adult Compendium values)¹:

A general vigorous row sits below a spin class or a 10 minute mile run. Once you hold 150 watts or more, rowing moves to the top of the list. Moderate kayaking and a moderate elliptical session match easy rowing under 100 watts.
