What is Retirement Planner Calculator?
A retirement planner calculator estimates how much you need to save each month to build a comfortable retirement corpus. It accounts for your current age, retirement age, expected monthly expenses after retirement, inflation, and the return you expect on your investments.
Retirement planning is one of the most important financial decisions you will make. This calculator shows you the gap between what you have and what you need, and gives you a clear monthly saving target so you can start today.
How does the Retirement Planner Calculator work?
Your monthly expenses are first inflated to the retirement year, then multiplied to estimate the total corpus needed. The calculator then works backwards to find the monthly investment required to build that corpus at your expected return rate.
A common rule of thumb is that you can safely withdraw about 4% of your corpus every year in retirement.
