📘 About the Retirement Savings Rule

Two rules of thumb make retirement planning easier. Save about 15% of your income every year, and aim for a corpus of about 25 times your yearly expenses, the idea behind the 4% withdrawal rule.

Enter your income, age, planned retirement age and yearly expenses to see your monthly savings target, the corpus needed and the years left.

🧮 Formula

Monthly savings target
Savings = Annual income × 15% ÷ 12
Corpus needed
Corpus = Annual expenses ÷ 4% (that is, 25 × expenses)
Years to retirement
Years = Retirement age − Current age

Where

  • Annual expenses = what you expect to spend each year in retirement
The 4% rule comes from US research. Inflation and returns differ in India, so use it as a starting point.

❓ Frequently asked questions

Are today's expenses enough to plan with?

No. Expenses will rise with inflation. Use the inflation calculator to project them to your retirement date.

Why 4%?

Historically a portfolio could support withdrawals of about 4% a year for decades. It is a guideline, not a guarantee.

What if I cannot save 15%?

Start with what you can and increase it each year as your income grows.

How much do I need to retire in India?

About 25 times your yearly expenses at retirement. With 6% inflation, ₹6 lakh of expenses today becomes about ₹34 lakh a year in 30 years, needing a corpus of about ₹8.6 crore.
