Enter your body weight, step height, and number of step-ups to calculate your calories burned doing step-ups. A 155 lb person burns about 10 calories for every 100 step-ups on a 6-inch step.

Step-Up Calorie Formula
The calculator uses a mechanical work model based on body weight, step height, and the number of step-ups completed. The result is converted from foot-pounds of work into kilocalories.
Calories (kcal) = Weight (lb) × Step Height (in) × Reps × 0.000108
- Weight: body weight in pounds (kg is converted at 1 kg = 2.2046 lb)
- Step Height: platform height in inches (cm and ft are converted internally)
- Reps: total number of step-ups completed
- 0.000108: conversion factor that bundles gravity, the inch-to-foot conversion, the foot-pound to kcal conversion, and an efficiency adjustment for the down-step phase
Assumptions: you fully step up onto the platform with both feet, you control the descent, and your mechanical efficiency is roughly 22 percent. The model counts the up phase as positive work and adds a smaller contribution for the eccentric down phase. It does not account for added load (dumbbells, weighted vest), arm swing, or extra impact at very fast cadences. For weighted step-ups, add the load to your body weight before entering it.
The three modes use the same core equation:
- By reps: solves the formula directly for calories.
- By time: estimates reps as duration × cadence, then solves for calories.
- Calorie goal: rearranges the formula to Reps = Calories ÷ (Weight × Height × 0.000108), then divides by your cadence to estimate workout time.
Reference Tables
Use these to sanity check the result and to pick a realistic pace.
| Body Weight | 12 in step | 16 in step | 20 in step |
|---|---|---|---|
| 130 lb | 16.8 | 22.5 | 28.1 |
| 160 lb | 20.7 | 27.6 | 34.6 |
| 190 lb | 24.6 | 32.8 | 41.0 |
| 220 lb | 28.5 | 38.0 | 47.5 |
Calories burned per 100 step-ups (kcal).
| Pace | Step-Ups / Minute | Best For |
|---|---|---|
| Slow | 10 to 14 | High platforms, weighted reps, beginners |
| Moderate | 18 to 24 | Steady cardio, circuits |
| Fast | 28 to 35 | Low platforms, conditioning intervals |
Example Problems
Example 1: By reps. You weigh 170 lb, use a 16 in box, and finish 200 step-ups.
Calories = 170 × 16 × 200 × 0.000108 = 58.8 kcal.
Example 2: By time. You weigh 150 lb, use a 12 in step, and work for 15 minutes at 20 step-ups per minute.
Reps = 15 × 20 = 300. Calories = 150 × 12 × 300 × 0.000108 = 58.3 kcal.
Example 3: Calorie goal. You weigh 200 lb, use a 20 in box, and want to burn 100 kcal at 20 step-ups per minute.
Reps = 100 ÷ (200 × 20 × 0.000108) = 232 reps. Time = 232 ÷ 20 = 11.6 minutes.
FAQ
Does step height really matter that much? Yes. Calories scale linearly with height. Doubling the box from 10 in to 20 in doubles the work per rep.
How do I count weighted step-ups? Add the external load to your body weight in the weight field. A 165 lb person holding 25 lb dumbbells enters 190 lb.
Why is the result lower than my fitness watch? Watches estimate calories from heart rate, which includes recovery cost, elevated breathing, and post-exercise burn. This calculator only models the mechanical work of lifting your body. The watch number is usually higher.
Does alternating legs change the result? No. Each full step-up is one rep regardless of which leg leads.
Is one leg up and one leg down counted as one rep? Yes. One rep is one complete up and down cycle.
