Estimate the walk, without pretending the number is exact.
Short answer
This walking calorie calculator estimates the calories a walk uses from your weight, minutes and pace, with a standard MET formula. Treat the result as a range, not an exact number. It is most useful next to your BMR, what your body burns at rest, and a daily walk you repeat with a team.
Use your weight, walking time, and effort to get a transparent MET-based estimate.
How the estimate works
The calculator uses MET values from the 2024 Adult Compendium of Physical Activities. A MET is how hard an activity is compared with resting. Calories ≈ MET × 3.5 × your weight in kg ÷ 200 × minutes.
Example: 30 minutes at a moderate 3 mph pace (MET 3.8) for a 180-pound woman is about 160 calories in total, including what her body would burn at rest anyway.
Why your watch shows a different number
Watches use their own formulas, heart rate and stride data. Neither number is exact. Pick one method and compare like with like over time.
What to do with the number
Use it as context, not as permission to eat more. The Get Your BMR quiz sets your daily calorie target assuming a lightly active week, so walks beyond your usual routine are a bonus on top.
Find your number first
Your BMR estimate, a daily calorie target & Coach Josh’s protein range, from four quick questions.
Two to four of you on one team: a friend’s, your own, or one you join in the app. Your team gets a name, a crest & a spot on the live leaderboard.
2. Walk + water, 3 days
Tuesday, Wednesday & Thursday. A step goal & a water goal sized to where you are today. The board updates as you walk & closes Thursday at midnight, Arizona time.
3. Friday winners
Friday morning the results go up. The winning team’s card glows gold, badges land beside names on the board, and a new round starts Tuesday.
Bigger isn’t better. Teams rank on their AVERAGE.
A team’s score is its average per woman, not its total. So two friends can beat a team of four, and every walker’s day counts the same. When one of you goes quiet, the others notice & send a nudge in team chat.
Your team card. The big number is the average per woman.The live leaderboard. Solo, team & global ranks for this round.
A transparent walking estimate
Choose your weight, time and effort. The result uses MET × body weight × duration and is an educational estimate.
1
Use actual walking time
Enter moving time, not the full time away from home if you stopped a lot.
2
Pick effort honestly
Comfortable & brisk mean different things to different people. Choose what matched your walk.
3
Compare like with like
Use the same method over time instead of comparing numbers from different devices.
Questions
Why is my watch different?
Wearables use different sensors, personal data & formulas, so estimates often differ.
Does terrain matter?
Yes. Hills, surface, weather, pace & fitness all change the real number.
Should I eat back the estimate?
This calculator cannot make personal nutrition recommendations. Use qualified guidance for that.

I’m Josh. I built Get Your BMR so you could see what your body burns at rest, & I built Walk & Water so you’d have somewhere to use it with people who notice when you show up.
I walk every round too: same board, same three days, on my own team. I don’t always win. Tap Chat with Coach in the app & it’s me who answers.
About 7 in 10 women who finish a round come back & play the next one.

Get Your BMR is Coach Josh’s free calculator. The 3-Day Walk & Water Challenge is where you put the number to work, and it runs inside the APEX: Walk & Water app on iPhone and Android.
