First, let me clarify - you're asking about body fat - not Body Mass Index. BMI is helpful in estimating whether you're overweight or not, and can be checked with a calculator online - but does not give you any real indication of body fat percentage. For that, you'll need a Body Fat Caliper tool. There are more accurate methods of determining body fat percentage, but this is the best solution if you're on a budget. Calipers are simple to use, fairly accurate, and don't hurt
You can get a rough estimate of your body fat by using an online measurement program. The way to get a true measurement though is by using a body fat caliper..
There are a number of charts online which calculate one's ideal amount of body fat based on sex and age. The numbers will differ slightly from site to site but not too much; one such chart can be found at http://www.fatfreekitchen.com/weightloss/body-fat.html.
