Excess Weight Loss calculator?

Does one exist somewhere out there? I know online BMI calculators are a dime a dozen, but I've yet to find one that will calculate EWL percentage.

Short of a calculator, would someone give me an easy way to figure this? I can write my way out of just about any cir****tance, but math?

~little whimper~

I'm its ***** It OWNS me. I cower at the sight of its cryptic symbols ... tremble with fear of fractions... go glassy-eyed at the mere suggestion of percentages.

Make it easy for me, please. A Web site where I can toss a few numbers into a few empty cells and hit a button that is clearly marked "caclulate my EWL."

Puh-leeease?

I love ya, man!

All you do is:
 
To get your total amount of excess weight, subtract your goal weight from your starting weight (I will use my own numbers as an example).
308.5 - 150 = 158.5

Then just divide how much you've lost so far by the total excess weight to get your %EWL so far.
66/158.5 = .4164

Convert to a percentage by moving the decimal point 2 spots to the right.
I have reach 41.64% EWL so far.

Maybe this helps?

I followed the link... it wants me to weigh 138lbs. according to the chart, I am waaaayy behind schedule, but I am a revision. sooo...

I'm not gonna sweat it... It will be what it will be. I haven't been this weight in over 20 years. So, I'm happy at the moment. : )

OK, Kathy -- you just had to ask!

Assuming that you have your goal weight (several options for what to use), you can use a small spreadsheet that I just wrote (3 blanks to fill in, clearly labeled). Take a look at this link, and PM me if you think it will work and I will grant you access to be able to just edit the numbers. The numbers in it are my numbers, just as an example.
