A body fat scale? Are we talking calipers or are we talking a scale that you input height and weigh yourself on? Because that's not fat that's BMI and having a high BMI just means you've got more of something on your body than a normal healthy person your height. The scale doesn't know how much of that is fat, muscle or bone. Also you're ripping yourself off if you're paying for a special scale to get BMI.
Neither, calipers are inaccurate and it's hard to test on yourself; and I'm not talking about a regular scale. How it works is you stand on the metal part and the scale passes an electrical current through your body. Fat is a poor conductor, while the rest of your body is more efficient at conducting electricity. The scale uses electricity to gauge your body density. The scale takes this number and uses a formula to convert that density figure to a body fat-exclusive figure. Obviously that last step is where the discrepancy can occur, but it's far more effective than measuring BMI. BMI is a really poor way of measuring fitness because a really muscular person would be considered "overweight" by BMI comparisons, but a body fat scale accounts for this, so you're more likely to get an accurate representation of your health. If I wanted BMI I could just go on the internet and get it for free.
