Calories Burned Jump Rope Calculator

The MET formula in one line

One line does the work: kcal per minute = MET x 3.5 x body weight in kilograms / 200. The 3.5 is the oxygen cost of sitting still in milliliters per kilogram per minute, the 200 turns milliliters of oxygen into kilocalories, and the MET is how many times harder the activity is than rest.

Convert pounds first: 130 lb / 2.20462 = 58.97 kg. Moderate skipping carries 11.8 METs in the 2024 Adult Compendium, so 11.8 x 3.5 x 58.97 / 200 = 12.18 kcal per minute. Fifteen minutes of that is 182.65, which rounds to 183 calories.

Body weight is the only personal input. Age, sex and fitness shift the true cost by a few percent, but none of them appear in the equation. The output is gross energy, so it counts the calories you would burn sitting still; the net figure subtracts that baseline.

Two worked examples at 130 and 180 pounds

Same cadence, different bodies. At 130 lb the moderate pace costs 12.18 kcal per minute, so 15 minutes burns 183 calories. At 180 lb the same quarter hour costs 16.86 kcal per minute and lands at 253 calories, 70 more for the session.

Weight and calories move together in a straight line, because the formula multiplies by kilograms. A 180 lb skipper carries 38.46 percent more mass than a 130 lb skipper and burns about 38 percent more per minute at the same rhythm. Ten minutes scales the same way: 122 calories at 130 lb, 169 at 180 lb.

The rate holds as the block grows. Thirty minutes at 130 lb is 365 calories, the same half hour at 180 lb is 506, and at 220 lb it reaches 618. The 180 lb figure rests on 81.65 kg of body mass, which is the only conversion the formula needs. Nothing in the formula drifts, because it assumes a steady cadence for the whole block.

MET values for slow, moderate and fast skipping

The 2024 Adult Compendium of Physical Activities lists rope jumping in three cadence bands plus a double under entry (2024 Adult Compendium of Physical Activities). The codes matter when you compare calculators, because some sites still quote the older 2011 table.

The 2011 edition put slow rope work at 8.8 METs; the 2024 update lowered it to 8.3. That one change cuts a slow pace estimate by about 6 percent, which is enough to explain a disagreement between two calculators given the same weight and minutes.

At 130 lb the three bands cost 8.56, 12.18 and 12.69 kcal per minute, and double unders 10.32. At 180 lb the same rows read 11.85, 16.86, 17.57 and 14.29.

General rope skipping is sometimes listed at 11.0 METs. Use the cadence bands when you know your rhythm, since 11.0 sits between slow and moderate and hides a real difference at either end.

Weight scales the total, cadence sets the band

The grid below comes straight from the formula, with body weight across the rows and cadence across the columns.

Read it by column and the power of weight shows up fast. Going from 100 lb to 220 lb multiplies body mass by 2.2 and calories by the same 2.2, which is why two people can skip side by side for the same 15 minutes and finish 100 calories apart.

Cadence moves the number less than most people expect. Across the full range, 8.3 to 12.3 METs, the rate rises 48.19 percent. From moderate to fast the step is only 4.24 percent, so a slightly quicker rhythm barely changes the total. A longer block or a heavier body moves it far more than a faster rope.

Double unders sit between slow and moderate at 10.0 METs. The extra effort per jump does not translate into a higher per-minute burn, because the rope turns once for every two jumps and the overall rhythm slows.

How 15 minutes of rope work compares with other cardio

Eleven point eight METs is close to twice the 6.0 MET line the CDC draws for vigorous activity, and one minute at that pace counts like two minutes of moderate work in the weekly guidelines (CDC, Physical Activity Guidelines for Americans, 2018). A 15 minute block therefore fills 30 minutes of the 150 minute weekly target.

Calorie for calorie, 183 is about what a 130 lb person spends in 51 minutes of walking at 3.5 METs, the value the same guidelines assign to a 3 mph pace. A 30 minute walk at that pace is 108 calories, so the rope returns 183 in half the time. The rope packs that burn into a quarter hour, which is the trade most people accept: less clock, more effort, more load on the feet.

That trade is why rope work suits a busy week and why it punishes a cold start. The 150 minute target is reachable in five 15 minute blocks if the cadence stays moderate; two of those blocks land the same calories as an hour of walking.

Intervals, double unders and rest breaks

Most sessions are not steady. A 40 second fast burst followed by 20 seconds of standing rest averages (12.3 x 40 + 1.5 x 20) / 60 = 8.7 METs. At 130 lb that is 8.98 kcal per minute, or 135 calories for 15 minutes, against 190 for the same quarter hour at a continuous fast pace.

Shorten the rest to 10 seconds and the same burst averages 10.14 METs, which recovers most of the gap. The work interval matters less than the ratio of work to rest, and the ratio is the number to write down if you want repeatable sessions.

Double unders land at 10.0 METs. Per minute they cost less than fast skipping, even though each jump is harder, because the rope passes under the feet once for every two jumps. Per skip they cost more. Expecting a bigger number from a double under set and getting a smaller one is normal.

Rest is not wasted time in the estimate, either. The formula prices the whole block at one MET, so a session with long pauses needs its average cadence rather than its peak cadence to come out right.

Skips per minute, sets and calories per 100 skips

At 110 skips per minute, 500 skips take 4.55 minutes and burn 55 calories at 130 lb, or 77 at 180 lb. Per 100 skips that is 11.1 and 15.3 calories, a figure that travels well between sessions of different lengths.

A 15 minute moderate block at 100 to 120 skips per minute holds 1,500 to 1,800 skips. Beginners often sit nearer 70 to 90 skips per minute, which is the slow band, and the 8.3 MET value already accounts for that lower rhythm.

Four 15 minute sessions a week come to 732 calories at 130 lb and 1,012 at 180 lb, which is 60 minutes of rope work against the 150 minute weekly guideline.

Count a 30 second sample and double it instead of counting a whole block. Trips and resets interrupt the rhythm, and the formula assumes a steady cadence, so a block with four stops burns less than the raw minute count suggests.

For a 100 calorie target at 130 lb, the moderate pace needs 8.21 minutes, which is about 903 skips. At 180 lb the same 100 calories arrive in 5.93 minutes, or 652 skips.

What the formula cannot see

The equation prices steady work at a fixed MET. It cannot see a beginner's extra arm swing, a higher jump or tension in the shoulders, and all three raise the true cost. It cannot see efficiency either: a skilled skipper at 120 skips per minute may spend less energy than the table value, because the movement has become economical.

It ignores the small rise in metabolism after hard intervals. That bump is real but modest, and it does not turn a 15 minute session into a 30 minute one.

Wrist trackers add their own error. Optical heart rate lags on short bursts, and most devices estimate from heart rate rather than cadence, so a rope session with brief spikes often reads high. Use the formula to plan and the tracker to spot trends.

Impact is the other blind spot. Rope work loads the feet and calves more than cycling at the same calorie cost, and a 180 lb skipper landing 253 calories worth of jumps takes more pounding than the number suggests. Build up slowly, pick a forgiving surface, and treat shin or heel pain as a reason to cut the minutes.
