Why plan for retirement?
Inflation quietly raises the cost of living every year, so the monthly budget that supports you today will buy far less by the time you retire. A retirement calculator helps you estimate the size of the corpus you need so your savings can fund your lifestyle for the rest of your life.
How this retirement calculator works
The tool inflates your current monthly expenses to their value at retirement, then works out the lump sum required to fund an inflation-adjusted income for your expected retirement years. It uses the "real" rate of return — your post-retirement return net of inflation — to size the corpus.
How to use the Retirement Calculator
- Enter your ages. Type your current age and the age you plan to retire.
- Add your monthly expenses. Enter what you spend each month in today's money.
- Set the assumptions. Choose an inflation rate and the return you expect after retirement.
- Read your target. See your future monthly expense and the corpus you need to build.
Frequently asked questions
Why is the future expense so much higher?
Inflation compounds every year, so even a modest rate can double your cost of living over a few decades.
What is the real rate of return?
It is your post-retirement return adjusted for inflation; using it keeps the corpus in today's purchasing-power terms.
How many retirement years should I assume?
Plan generously — 25 to 30 years is common — so you do not outlive your savings.
Does this account for existing savings?
No. It sizes the total corpus you need; subtract any savings you already have to find the gap.
