There are many ways to calculate body fat. But if you want to do it at home, there are only two methods that are really convenient and reliable.
Calculate Body Fat With Accu Measure Body Fat Calipers
This is all about taking a skin fold measurement – otherwise known as the 'pinch an inch' method.
It's based on the fact that most of the fat on the body is located directly underneath the skin.
Pinch the skin about one inch above your hip bone, and measure how thick the skin fold is with the body fat calipers.
Then look up the measurement of your skin fold in the conversion table that comes with the fat calipers to work out your body fat percentage. It'll also tell you whether you're lean or average.
Now, this poses a bit of a challenge for you to calculate body fat. You'll need to practise pinching the right amount of skin in the same place every time.
One way to be sure is to use a ruler and a felt pen to mark the spot where you're going to pinch. Test it several times on the trot to see if you get any variation in the results. If you get wild fluctuations in the results, you'll just need to practise more.
(By the way, this is not recommended for obese people as the results will not be accurate.)
This is the most affordable way to get your own body fat measurement fairly accurately.

There's a lot of debate about the accuracy of these two methods.
A lot of different factors can affect how accurate the results are. Such things as age, sex, race, body temperature, body water level etc. The thing is, there is as yet no way to measure the body fat percentage exactly (apart from dissection, that is!).
But these two methods will at least give you a ball park figure to work with.
To remove as many variables as possible, try these two tips:
