How do I accurately calculate my daily calorie burn ?

So I am female, 41years old, 5’8” and about 194 lbs.
According to my new Fitbit my calorie burns for the last three days are:
3,142 calories 3,528 calories and 3,415 calories.
My step counts are high (18,000-20,000 per day) but STILL these calorie counts seem very high for me? I would love to believe I burn that many calories but is it too good to be true?
How do you guys determine an accurate calorie burn for the day?
(Also I checked the Mayo Clinic - it says I would burn 1950 calories a day if I’m inactive and 2,750 if I was very active.).

About right.. I'm 6'+ and walk avg of 10k steps.. daily total burn is 3000 more or less using Fitbit tracker2

Are you just walking or are you doing any higher impact cardio? If it's simply walking, I'd put you at 2800-3000. If you're doing other cardio, it may be close though.0

Why not sync your device to MFP, set goal (weight loss rate or maintenance) in your profile, and try it for 4-6 weeks, while logging eating as accurately as you can? Then you'll know how accurate it is, by comparing your target weight loss rate to your actual weight loss (adjusting via math for any materially over/under days by assuming 3500 calories = roughly one pound of gain or loss).
If you want to eat the same number of calories every day, average the data from your device over a number of days, and use that as your starting estimate.
No matter where you come up with an initial calorie goal, it's an estimate. Actual experience after that 4-6 weeks lets you adjust to a more real-data-based estimate. Keep using your own data and adjusting, and you'll have a plenty accurate enough estimate to achieve your weight management goals, whatever they may be.3 -
Sounds accurate to me. I'm 5'3", 112 pounds, and I maintain on 2000 to 2300 calories per day on average. I have been maintaining for three years.2

I have found my fitbit to very accurate with its estimation.3

So you're well beyond MFPs definition of Very Active... and you get more calories than MFPs very active setting...
Whether the figures are accurate for you will ultimately depend on your logging and your body.
So eat as if your Fitbit is correct, and 4 weeks or so later evaluate if you're losing at the expected rate based on how your weight trend has changed.5 -
I linked my Fitbit to MFP and started out by eating back half the calories i earned through the “adjustment” Fitbit gave me each day (roughly, since it’s a moving target). I had MFP set to sedentary so this was a sizable adjustment most days.
But after 6 weeks, I did the math and realized I was losing faster than expected. I could actually eat back all the adjustment calories.
But based on other threads, it sounds like the reliability of Fitbit can depend on the person and the model, so you need to get your own data and see what works for you.0 -
I'm 29. 5ft6 and 220ish I burn about 3500 average (2700 to 3800 ish) and this has been pretty accurate for me. I get pretty highstep counts. 12000 to15000 average. I work on my feet 8 hours a day. Lots of bending and lifting. I also have four young children. I'm a natural fidgeter. I NEVER sit still lol. This has been pretty accurate for me. When I think to when I was gaining weight. .. I was eating ALOT ( like whole pizzas and 2 whoppers at a time)2

Personally I never rely on tech to determine calorie counts nor the numbers you see on the internet. People simply can't be grouped into one category and so determining how many calories you have burned doing any particular exercise (or none at all) is usually not highly accurate.
Age, size, metabolism, gender all play a part in how many calories you burn per day. Fitbit and other tech have been known to be inaccurate and shouldn't be relied on. Use common sense, healthy eating and plenty of exercise combined with a scale (or tape measure) to determine weight loss.
The "tech" could be very misleading... https://www.fool.com/investing/2018/08/27/can-you-trust-your-fitbit-tracker.aspx

Sync it, log food accurately, eat back at least half of your adjustment and review in 4-6 weeks against your actual weight loss and adjust as necessary. Real world results are what matter but generally the numbers aren't that far out in my experience.
There's no reason that wouldn't be that accurate, I regularly burn those sort of numbers and lose weight as expected I'm a little younger, a little shorter and about 20lbs heavier, but only walking about 10-14000 steps per day.
A lot of the studies like those in the articles above, do not take into account the fact that most devices have a settling in period and are just strapped on brand new. I used a spreadsheet (I think @PAV8888 put together) to determine how accurate my own was by logging food as accurately as possible and tracking my weight and trendweight for 5 weeks, found that my Garmin was about 2% underestimating my calorie burns.1 -
I found my Fitbit overestimated my total calorie burn - I would often get 3000+ since swapping to Garmin I am usually around the 2700 mark0

And my Garmin dramatically underestimates mine (like 25-30%, as compared with almost 4 years of food logging and weight loss/maintenance data).
That's the nature of very good statistical estimates (which is all that fitness trackers can give us): They come close for most people, are further off for a few, and way off for a very small minority. Different devices are likely to differ a bit for any given individual: Different sensors, different algorithms, maybe slightly different research as the foundation.3 -
my 28 day average is 15,254 steps and 2785 calories.0

My fitbit versa has been spot on for my calorie burns, daily and exercise burn. I average 16000 steps on a slow day and 25000 on my 10k training days. I base my daily calories off of my burn, and I have lost 60lbs now at the exact time line I've expected from using my Fitbit as a guide.2
