Both those links to the same one. But I think you mean this one for the "accurate" one:

I would use that one, and choose Katch McArdle formula and use body fat%. This will be more accurate than the calculators that do not factor in body fat %.

And since Scooby's site for BF% estimate is by skin-calipers only, here is a site to get BF%.

As long it's it's within 5%, there's hardly any difference to the end figures.

And if you don't want to use Katch BMR, at least use Mifflin, which is about 5% more accurate than Harris BMR, though both are inflated when overweight.

Thank you for the link.

There are 4 different "results" listed after I add in all my numbers. The "average" being 35% ...is that the number I would use ?

Yep. Just to comment, if they are separated by more than 5%, then one end of the range is more accurate.

So save the stats. Next measurements after you lose some inches, one end will move more than the other end of the range, the moving side is least accurate, other end is more accurate.

But keep using avg which should move more to correct side. So in theory, you could even appear to go up in BF% as accuracy increases.

If you want to log your stats and those calculators, just use spreadsheet linked in this topic.

Saving for later

This is what it states on his website:

All web based calorie calculators *estimate* your BMR based upon various research that has been done. These research studies have come up with various formulas that are used to estimate your calories. For example, two of the most commonly used equations come from the research done by Harris-Benedict in 1919 or Mifflin-St Jeor done in 1990. The Mifflin-St Jeor appears to be about 5% more accurate than the Harris-Benedict equations, this is probably because the older research was based upon a population that was much leaner and more active than we currently have. These equations based upon the research are easy to use but only get you to within about +/-10% accuracy on the caloric estimation which is accurate enough for most uses given the difficulty of counting the calories accurately. The reason for the +/-10% variation is twofold. First, because these equations use weight and not lean body mass in their calculations. The energy required to maintain muscle is higher than the energy required to maintain fat so both these equations will be off for either very lean or very fat people. To get around this problem there are two more sets of equations based upon the research by Katch-McArdle and Cunningham which are based upon Lean Body Mass (LBM) instead of weight. Everything has flaws and the Cunningham and Katch-McArdle equations do to. Their flaw is that they completley disregard the energy required to maintain the bodyfat so they are not accurate for untrained obese people. Whose equations should you use for best accuracy? If you are fairly muscular and lean (4-pack abs or better), I would recommend the Katch-McArdle formula. If you are just starting on your fitness journey and are not yet strong or lean then I recommend the Mifflin-St Jeor equation.

Thanks. Just embarking on eating more and adding more strength work. Today I calculated my TDEE as 1946 and this is about the same as my maintenance calories plus usual exercise with MFP so it won't work out too different for me. Now I've got to get the exercise sorted!
