To spend ₹50,000 a month in today's money from age 60 to 85, you need about ₹7,71,48,478 at retirement. Your savings are projected to reach ₹6,54,23,906, leaving a shortfall of ₹1,17,24,572.
Projected corpus vs corpus needed
- Projected corpus₹6,54,23,906 (84.8%)
- Shortfall₹1,17,24,572 (15.2%)
Show the calculation steps
- Years to retirement = 60 − 30 = 30; years in retirement = 85 − 60 = 25.
- Monthly expense at retirement = ₹50,000 × (1 + 6%)^30 = ₹2,87,175.
- Corpus needed = present value of 25 years of expenses that rise with inflation while the corpus earns 7%: ₹7,71,48,478.
- Projected corpus = savings grown ₹1,98,37,399 + SIP grown ₹4,55,86,506 = ₹6,54,23,906.
- Total monthly SIP needed to close the gap = ₹25,144 (₹5,144 more than you invest now).
- Assumes withdrawals at the start of each year that rise with inflation, and constant returns. Results are estimates, not advice. Plan for a margin of safety.
What the calculator does
It inflates today's expenses to your retirement date, works out the corpus needed to fund them until the age you choose while the money earns a post-retirement return, and compares that with what your savings and monthly investing are projected to reach.
Making the plan more robust
The plan is sensitive to inflation and returns, so test cautious values. Small changes in the years to retirement or in the life expectancy can change the result a lot. Reviewing your plan every year keeps it realistic.
Formula
Expense at retirement = Expense today × (1 + inflation)^years
Corpus = Σ (yearly expense × ((1 + inflation) ÷ (1 + return))^t) over the retirement years
Projected corpus = Savings × (1 + i)^n + SIP × ((1 + i)^n − 1) ÷ i × (1 + i)
Where:
- i
- = Monthly return before retirement
- n
- = Months until retirement
- t
- = Year of retirement, starting at 0

Frequently asked questions
How much money do I need to retire?
It depends on your spending, inflation, how many years you need the money to last and your returns. The calculator works it out from those inputs.
What return should I use after retirement?
A lower return than before retirement, because portfolios usually become more conservative. Try a few values.
What if I have a shortfall?
Increase your monthly investment, retire later, reduce planned spending or aim for a higher return. The calculator shows the extra SIP needed.
