According to most experts, your retirement income should be around 80% of your pre-retirement annual income. For example, if you have an annual income of $100,000, you'll need at least $80,000 annually to maintain a comfortable retirement life.
However, to estimate how much retirement income you need, you must first be aware of your retirement objectives. Imagine the sort of lifestyle you wish to have when you retire, and most importantly, what retirement means to you. Being realistic, as well as having precise and quantifiable retirement objectives, may allow you to have a more accurate evaluation of how much you need to set aside.
