Rowing Calorie Calculator: How Many Calories Does Rowing Burn?
A 75 kg rower holding a 2:10 split burns roughly 800 kcal per hour on the erg, and a hard 2:00 split pushes past 1,000. Rowing is one of the highest calorie burns in sport, which is exactly why rowers are famous for eating more than almost any other athletes.
Most rowing calculators guess from vague effort levels. This one works the way rowers actually think: enter your average split per 500m and the calculator converts it to watts, then to calories, using the same published formulas Concept2 performance monitors are built on, corrected for your body weight. The monitor itself assumes a 79.5 kg rower, so lighter rowers see their burn overstated on screen and heavier rowers see it understated. This calculator fixes that, which is the number that matters when you're planning food around training.
If you row on the water, switch the top setting and it estimates from published exercise-science energy values for easy, steady and race-pace rowing instead.

Why rowers struggle to eat enough
Twice-daily sessions can push a serious rower's needs to 5,000 kcal a day or more, and there's a limit to how much porridge, pasta and rice anyone can face. That's the gap Phoenix Bars were built for: high-calorie bars that pack up to 557 kcal into one 120g bar you can eat between the boathouse and the bus. One bar after each session quietly closes a deficit that three extra plates of food can't.

FAQs
How many calories does 30 minutes of rowing burn?
At a steady 2:20 split, a 75 kg rower burns roughly 320 to 350 kcal in 30 minutes. At 2:05, that rises to around 450.
Is the calorie figure on the erg screen accurate?
It's accurate for a 79.5 kg rower, because that's the weight the monitor assumes. Enter your split and real weight above for your corrected number.
Does rowing burn more calories than cycling?
At equal effort they're close, but rowing works more muscle at once, so most people sustain a higher burn per hour on the erg. You can compare using our cycling calorie calculator.
