Not long ago, I released a simple Rucking Calorie Calculator — and it’s helped a lot of people finally understand how many calories they’re really burning with a weighted pack.
Recently, I updated that tool to also include pack type — weighted vest vs backpack — because it matters. A rear-loaded pack (like most rucksacks) changes your center of gravity, posture, and strain. In fact, it can burn 7% more calories than a balanced vest. That update made the calorie calculator even more accurate.
But something still felt missing.
So I built a new tool — the Rucking Weight Loss Calculator.
🔍 The Bigger Question
People don’t just want to know how many calories they’re burning on a single ruck.
They want to know:
“How long will it take to lose this weight if I keep doing this?”
This new tool gives you that answer.
🛠️ What It Does
You enter:
- Your current weight, target weight, height, age, and sex
- Your daily calorie intake
- Your rucking distance, pack weight, pack type, and intensity level
It tells you:
- 🔥 How many calories you’re burning from rucking
- 💪 Your total daily calorie burn (including BMR and activity)
- 📉 Your daily calorie deficit
- ⏳ Estimated days to reach your fat loss goal
It’s not a gimmick — it’s the math.
And the numbers reflect what most smart watches miss: the weight you’re carrying, the terrain you’re on, and the real effort it takes to ruck consistently.
⚖️ This Is How I Lost 90 Pounds
This isn’t theory.
I used rucking — and consistency — to drop over 90 pounds. Or even better… get below 10% body fat. I used rucking to burn the last bit of fat, the hardest bit.
Now I’m a certified personal trainer building the tools I wish existed when I started.
Whether you’re using the calorie calculator to estimate your next session, or the weight loss calculator to plan your long-term goal — these tools are for you.
Because nobody else is giving you accurate numbers.
And inaccurate numbers can kill your momentum.
This gives it back and It’s free 🙂

Thanks for this calculator! One hidden problem in weight loss, is the extra weight wh3n you start, helps speed loss. As you lose weight, you lose rhe extra momentum the excess weight provided and got you off to a great start. The ruck weight, counteracts that.
