The following macro calculator applications are the best – carefully designed and coded:

Can I calculate my own macros?

Yes you can.

If you really want to do your own calculations – read the guide to counting macros. Note that there is a bit of math involved.

Are macro calculators accurate?

No calculator can be 100% accurate as there are many variables that govern our unique metabolism.

This is why many of the best sites offer macro coaching where one-on-one assistance will increase accuracy.

Why are results different even though I enter the same stats?

Different macro calculator apps may show different results. This is because formulas have been tweaked slightly – often due to real feedback from clients.

What is the most accurate calculator?

The best calculators are based on standard formulas for calculating BMR, REE, and TDEE.

However some adjustment comes in the form of your activity level. Different calculators may apply different multipliers.

We stand by our own macro calculator as it has formed the basis of excellent results from many hundreds of clients.

Getting more precise macros

If you want a more precise calculation, you can have metabolic testingdone by a certified testing facility. This is expensive and is generally not covered by insurance.

Rest assured, most people can use estimations to accomplish their fitness goals without the need for costly metabolic testing.

If none of the macro calculator app formulas are working for you (give it a few months), try metabolic testing. You could also take a metabolic panel blood test to find other reasons why your metabolism is slow.
