You can use these example charts to roughly estimate a goal body fat percentage.
You can also use them for now to roughly estimate your current body fat %, before you have the necessary tools to properly measure body fat % accurately. However, you should obtain an accurate body fat % measurement at some point to get accurate results. Read the fully detailed instructions for how to cheaply take body fat percentage (%) measurements on your own at home here: Body Fat Percentage(%) Measurement Guide

Proper Exercise is important for the best physical appearance while losing fat (for both men and women), for overall good health, for reaping the functional benefits of having muscle, and for raising TDEE (meaning you can eat more calories without gaining fat). But exercise should just not be considered a way to "burn" any calories.

As accurate as the information you provide. If you provide very accurate body weight and body fat percentage measurements, it will be very accurate.
Figure 1. Summary of Fat Gain, Fat Loss, & Muscle Loss Produced Depending on the Amount of Calories Consumed in a Day
Total Daily Energy Expenditure (TDEE): This is how many calories (energy) your body needs per day to function. Consume this many calories per day to maintain the same amount of body fat.
Calorie Deficit: This is when you consume less calories in a day than your TDEE. Producing a calorie deficit causes your body to break down tissue, including body fat (which creates fat loss), to get the rest of the energy it needs for that day.
