What this result does not account for
- The duty cycle is an estimate unless you measure it with a stopwatch or a skip count.
- Compendium values describe steady two-foot skipping and cannot distinguish a relaxed bounce from double unders at the same nominal cadence.
- Double unders are probably understated, because the Compendium groups them with fast single skipping.
- The 3.5 ml/kg/min resting constant is a population average from a single reference subject.
- Rope length, weighted ropes and jumping surface all affect cost and are not modelled.
In short: At 70 kg and 110 skips a minute the rate is 14.46 kcal per minute of rope-turning — about 0.131 kcal per skip. But a MET value describes time with the rope MOVING. A 20-minute session at a realistic 60% duty cycle is 12 minutes of work, not 20, so the honest figure is 174 kcal rather than the 289 a naive calculator reports.
Formula
The MET value is multiplied by the minutes the rope was actually turning, not by the length of the session. The remaining minutes are costed as standing recovery at 1.8 MET rather than as nothing, because someone catching their breath is not at rest.
Worked Example
- Time the whole session. First jump to last, including every rest and every trip. That is the wall-clock figure.
- Estimate honestly what share the rope was moving. Beginners are often near 40%; a skilled skipper in long sets reaches 80% or more.
- Pick the pace band. Under 100 skips a minute is slow, 100 to 120 moderate, 120 to 160 fast. Double unders sit with the fast band in the Compendium.
- Read net rather than gross. Net removes the resting metabolism you would have spent anyway.
- Compare against the naive figure. The page shows what a calculator that ignores the duty cycle would have told you, which is usually far more.
70 kg, 20-minute session, moderate pace, 60% duty: 174 kcal net against the 289 a naive calculator reports.
Strengths & Limits Of This Model
Where this engine is strong
- Applies the MET value to rope-turning time rather than to the wall clock, which no other jump rope calculator does.
- Costs the rests as standing recovery instead of ignoring them entirely.
- Shows the naive figure alongside, so the size of the usual error is explicit.
- Converts the duty cycle into a prescribable work-to-rest ratio.
Where it stops
- Requires an honest estimate of a quantity most people have never measured.
- Inherits the MET convention's weaknesses, including the resting constant.
- Cannot price the skill component, which is often the real reason to skip.
Practical Use Cases
Costing a realistic beginner session
A beginner tripping every few jumps may be skipping for a third of the session. Assuming otherwise inflates the answer by a factor of three.
Prescribing intervals
Setting a work-to-rest ratio makes the duty cycle a plan rather than a guess, and the interval card shows the ratio that produces the figure you entered.
Comparing jump rope against running
Skipping matches running minute for minute while the rope turns. The honest comparison accounts for the fact that runners do not stop.
Tracking progress that is not weight loss
Rising duty cycle at the same session length is a clean measure of skill improvement, independent of how many calories anything burned.
Methodology & Editorial Standards
Energy is estimated with the MET relationship, kcal = MET × 3.5 × body mass in kg ÷ 200 × minutes, using rope-jumping values from the 2024 Adult Compendium of Physical Activities: 8.8 for under 100 skips per minute, 11.8 for 100 to 120, and 12.3 for 120 to 160 and for double unders. The departure from every other jump rope calculator is that those MET values are applied only to the minutes the rope was actually turning, obtained by scaling the session length by the duty cycle, rather than to the full wall-clock duration. The remaining minutes are costed as standing recovery at 1.8 MET, on the basis that an athlete catching their breath is neither working nor at rest. Both gross and net figures are reported, net subtracting one MET so the resting metabolism the user would have spent anyway is excluded. Skip counts use band midpoints of 85, 110 and 140 turns per minute.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Jump Rope Calories Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How many calories does jumping rope burn?
While the rope is turning, about 14.5 kcal per minute net for a 70 kg adult at 100 to 120 skips a minute. Across a whole session it is far less, because nobody skips continuously: at a realistic 60% duty cycle a 20-minute session is about 174 kcal net, not the 289 that multiplying the MET value by twenty minutes would suggest.
What is a duty cycle and why does it matter so much?
It is the share of the session the rope was actually moving. MET values for rope jumping describe rope-turning time, but every calculator multiplies them by the wall clock. For a beginner who trips every few jumps, those two numbers differ by a factor of two or three, and the calorie figure differs by the same factor.
How many calories is 1,000 skips?
At 110 skips a minute a thousand skips takes about 9.1 minutes. For a 70 kg adult that is roughly 120 kcal net, or about 0.131 kcal per skip. Skip count is the most reliable thing to track, because unlike session length it does not depend on how often you stopped.
What MET value should I use for jump rope?
The Compendium gives 8.8 for under 100 skips a minute, 11.8 for 100 to 120, and 12.3 for 120 to 160. Double unders are usually grouped with the fast band, which probably understates them — the Compendium does not distinguish them properly.
Does jumping rope burn more calories than running?
Minute for minute while the rope is turning, yes: moderate skipping is about MET 11.8 against roughly 9.8 for running at 10 km/h. Across a real session the runner usually wins, because running is continuous and skipping is not. That is the whole point this page exists to make.
How do I measure my real duty cycle?
Two ways. Run a stopwatch and stop it every time the rope stops, which is fiddly but exact. Or count your skips and divide by your cadence: 1,200 skips at 110 a minute is 10.9 minutes of work regardless of whether the session lasted 15 minutes or 25.
Is jump rope good for weight loss?
It is time-efficient and needs almost no equipment, which are real advantages. But a hard 20-minute session at a realistic duty cycle is under 200 kcal net — about 23 grams of fat. Exercise of any kind is a slow lever on body composition, and skipping is no exception however much it hurts.
Why does the calculator still count calories during rest?
Because someone standing and breathing hard between sets is not at rest. Recovery is costed at 1.8 MET, which is a little above quiet standing and well below skipping. Counting it as zero would understate the session in the opposite direction to the error this page exists to fix.
Do double unders burn more calories?
Almost certainly, but the Compendium does not give them their own value and groups them with fast single skipping at 12.3 MET. They demand more power per jump and are usually done in shorter sets, so the duty cycle tends to fall even as the intensity rises. Treat the figure as conservative.
Does body weight change how many calories I burn skipping?
Yes, close to linearly. At moderate pace a 55 kg person burns about 11.4 kcal per minute of rope-turning and a 95 kg person about 19.6. Weight is the single most important input in any MET calculation, which is why every calculator that assumes a default weight is wrong for almost everyone.
Is this jump rope calories calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
Which currency does it use?
Amounts display in US$ accounting format, but the underlying mathematics is currency-agnostic. The result is identical in any currency, so simply read the figures in your own.
Why does a result show an em-dash?
An em-dash indicates the calculation is not defined for the inputs given — typically a division by zero or a value outside the valid domain. We show a dash rather than a misleading number.
How do I report an error?
Email apexconverter.praxiscalc@gmail.com with the tool URL, your exact inputs, the output received and the output you expected. Verified mathematical errors are patched within 72 hours.
