What should my TDEE be?

I'm really REALLY bad at math, so I just need a little help with figuring out my goals.

My estimated BMR (based on Mifflin and Fitbit) is 1610. This is the number of calories I want to eat a day.

I want to eat a 20% reduction of my TDEE?

How many calories should I burn a day in order for 1,600 to equal my TDEE-20%?

    BMR is not TDEE. We need to know how active you are to figure TDEE, then figure TDEE-20%

    No. You misunderstood me.

    I am a lazy bum, My TDEE-20% is less than my BMR. I don't want to go under my BMR, nor do I want a deficit of less than 20%. So, instead, I want to INCREASE my activity level enough so that I can eat my BMR and still be eating a 20% reduction of my TDEE. I'm just not sure how to figure that out.

    Or basically x-(20%x)=1610

    How do I solve for X?

    This is the formula 1610/(.8)

    2012.5 TDEE

    Basically your living of your life needs to total 400 calories.

    Edit to add: that's not 400 calories of exercise. That's probably less than 200 of "exercise." Most if that 400 you'll get from living your life.

    Thank you.

    I know how to figure out the percentage of something (ie: I know how to find out the price of a shirt that's on sale for 15% off if I know the original price. However, I don't know how to figure out the original price if I know the final price and that the shirt was discounted by 15%.

    multiply it by 1.15

    multiply it by 1.15

    $100-15%=$85

    But 85 x 1.15 =\= 100

    yup, you're right. i messed up.

    multiplying 1.15 by 85 actually adds 15% of 85 to 85.

    Just take the discounted price ($100) and multiply by 100. Then take that number and divide it by the difference in the percentages. (100 - 15% off = 85). See Below.

    so if you buy a shirt for $85, and you know it was discounted for 15% then...

    $85 x 100 = 8500
    8500 / 85 = 100

    The shirt was originally $100.

    Divide it by .85

    I.e. If the discount is x%, then divide by (100-x)%
