Planning for retirement is something many people think about, but it can be difficult to know exactly how much money will be needed. A common question is how much someone should save to retire comfortably. This is where a retirement calculator becomes useful. A retirement calculator is a financial planning tool designed to estimate how much money a person may need in the future based on their income, savings, and lifestyle expectations.

Understanding how a retirement calculator works can help people make smarter decisions about saving, investing, and preparing for life after work.
