Retirement Calculator

Retirement planning comes down to two numbers: how big a fund (corpus) you need on the day you retire, and how much to invest each month until then to build it.

About this calculator

Enter your age, when you plan to retire, how long to plan for and your monthly expenses today. The calculator grows your expenses with inflation, works out the corpus that can pay them for the whole retirement while still earning a return, and shows the monthly SIP to reach it after counting the savings you already have.

How to use it

  1. Enter your current age, retirement age and the age to plan until.
  2. Enter your monthly expenses today and expected inflation.
  3. Enter what you have saved so far for retirement.
  4. Enter expected returns before and after retirement, then read the corpus and SIP.

The formula

Corpus = E × [1 − ((1 + g) ÷ (1 + r))n] ÷ (r − g) × (1 + r)
E
yearly expenses in the first year of retirement, after inflation
g
inflation during retirement
r
the return the corpus earns after retirement
n
years in retirement

This is the present value of expenses that rise every year, paid at the start of each year.

Worked example

Age 30, retiring at 60, planning until 85

  1. Expenses of ₹40,000 a month today become ₹2,29,740 a month at 60, with 6% inflation.
  2. To pay that for 25 years while earning 7%, you need ₹6,17,18,783 at 60.
  3. Savings of ₹5 lakh growing at 10% become ₹87,24,701. The rest needs a monthly SIP of ₹23,250 from now.

What the result means

The corpus looks very large because of inflation over 30 years. Starting earlier lowers the SIP sharply, as does a few more years of work.

Count EPF, NPS and other retirement savings in “savings so far”, and reduce expenses by any pension or rent you will receive.

Assumptions

  • Expenses rise with inflation every year.
  • Returns and inflation stay constant.
  • The corpus is fully used up by the end of the planning age.

Limitations

  • Medical costs often rise faster than general inflation; consider a higher figure.
  • Taxes on returns and withdrawals are not included.
  • Real returns vary year to year, and a fall early in retirement matters most.

Frequently asked questions

How much money do I need to retire in India?

It depends on your expenses, age and returns. As a rough check, many planners suggest a corpus of 25 to 35 times your first-year retirement expenses.

What inflation should I use?

6% is a common long-term assumption for India; use 7% or more if you want a safety margin.

Should I plan until 85 or 90?

Plan for longer than you expect to live. Running out of money is a bigger risk than leaving some behind.
