Retirement Corpus

The Retirement Corpus Calculator estimates the total savings you need to retire comfortably and shows the monthly investment required to build that corpus. It factors in your current age, desired retirement age, expected annual expenses, inflation rate, and expected investment returns. The calculator models both the accumulation phase (while you are working and investing) and the distribution phase (after retirement when you are drawing down the corpus). It ensures the corpus lasts through your expected lifespan with inflation-adjusted withdrawals. This is one of the most important financial planning calculations. Starting early makes a dramatic difference — a 25-year-old needs to save far less monthly than a 35-year-old for the same retirement lifestyle because of the extra decade of compounding.
