What is a Retirement Corpus Calculator?

Your retirement corpus needs to cover expenses that are both higher than today (due to inflation) and required for potentially decades after you stop earning. This calculator projects your future monthly expenses at retirement, then works out the corpus needed to sustain them for your expected years in retirement.

It accounts for the fact that your corpus keeps earning returns even during retirement — so you don't need to save the full sum of all future expenses, just enough that returns and withdrawals balance out over your retirement years.

Why Inflation Matters So Much

  • ₹50,000/month today could need to be ₹2,00,000+/month in 25 years at typical inflation.
  • Underestimating inflation is one of the most common retirement planning mistakes.
  • The 'real rate of return' (return minus inflation) is what actually determines how far your corpus stretches.

Frequently Asked Questions

How is this different from a simple savings target?+

It explicitly accounts for inflation eroding your expenses' purchasing power and for your corpus continuing to earn returns throughout retirement, both of which a flat 'save X amount' target usually misses.

What return rate should I assume for post-retirement?+

A more conservative rate than your pre-retirement portfolio is typical, since retirement portfolios usually shift toward safer, lower-return assets.

Does this account for a pension or other income in retirement?+

No — this calculates the corpus needed to fund 100% of your expenses. If you'll have pension or rental income, your actual required corpus would be lower.
