An easy to estimate your body fat level is the Anthropometric / U.S. Navy method / YMCA formula

This method takes waist, neck, and height circumference for men and
hips, neck, and height for women. A U.S. Navy Method calculator is available on this website

The Navy Body Fat test and the YMCA formula are accurate within 1-3% for most people.
Otherwise for a more accurate measure of your body fat. Ask a gym trainer to do it with a skin fold caliper.
However the water displacement test is the most accurate way to determine body fat percentage. This method is expensive and requires special equipments.
