Retirement Calculator

What is the Retirement Calculator?

A comfortable retirement needs a corpus large enough to pay for 25–30 years of expenses that keep rising with inflation. The retirement calculator works out how much you need and whether your current savings plan will get you there.

Enter your age, planned retirement age, current savings, monthly contribution, expected return, inflation and current monthly expenses. The calculator inflates your expenses to your retirement date, sets the target corpus at 25 times that yearly expense (the 4% rule) and compares it with your projected savings.

How to use the Retirement Calculator

1. Current Age (sample: 30)
2. Retirement Age (sample: 60)
3. Current Retirement Savings (₹) (sample: 15,00,000)
4. Monthly Contribution (₹) (sample: 25,000)
5. Expected Return (% per year) (sample: 10)
6. Inflation (% per year) (sample: 6)
7. Current Monthly Expense (₹) (sample: 50,000)
8. Press Plan Retirement (results also refresh as you type). The result card shows the Projected Retirement Corpus, along with Projected Corpus at Retirement, Shortfall, Annual Expenses at Retirement and Years to Retirement.

Formula used

Target corpus = 25 × Annual expenses at retirement

• Annual expenses at retirement = current monthly expenses × 12 × (1 + inflation)^years to retirement
• Projected corpus = current savings and monthly contributions compounded monthly at the expected return

The 25× multiple corresponds to a 4% first-year withdrawal rate. For early retirement or low-return portfolios, a larger multiple (30–33×) is safer.

Tips for using the Retirement Calculator

• Start early — 10 extra years of compounding can halve the monthly saving you need.
• Count EPF, PPF and NPS balances in current savings.
• Plan for healthcare costs separately; medical inflation often runs at 10–14%.
