Existing savings compound at the pre-retirement return rate. Post-retirement corpus uses real return (after inflation). Results are indicative only.
What is a Retirement Corpus Calculator?
A Retirement Corpus Calculator helps you estimate how large a corpus you need to accumulate by retirement to sustain your lifestyle for the rest of your life — without running out of money. It accounts for inflation (which erodes purchasing power), your post-retirement investment returns, and your expected life span to compute the exact corpus required.
This calculator goes further by factoring in your existing retirement savings — EPF balance, NPS corpus, PPF, mutual fund investments, and any other assets earmarked for retirement. It compounds your current savings at the pre-retirement return rate, shows you how much they will grow to by retirement, and calculates only the additional monthly SIP needed to bridge the remaining gap.
How to Use This Retirement Corpus Calculator
- 1
Enter your personal details
Current age, planned retirement age, and life expectancy. India's average life expectancy is ~70 years, but planning to 85-90 is prudent for financial security.
- 2
Set your current monthly expenses
Enter today's expenses. The calculator inflates this to your retirement date using the inflation rate you specify to find your monthly expense at retirement.
- 3
Add your existing retirement savings
Enter the total of your EPF, NPS, PPF, mutual funds, and any other investments set aside for retirement. This reduces the gap and the SIP you actually need.
- 4
Set inflation and return assumptions
Use 6% inflation. Pre-retirement return: 10-12% (equity-heavy). Post-retirement return: 6-8% (conservative, debt-heavy for capital protection).
- 5
View your gap and required SIP
The calculator shows the required corpus, how much your existing savings will grow to, the remaining gap, and the additional monthly SIP needed to bridge it.
How Much Do You Really Need? Age-Based Benchmarks
These benchmarks assume retirement at 60, life expectancy of 85, 6% inflation, and 7% post-retirement return. Use them as a quick sanity check against what the calculator computes for your specific inputs.
| Monthly Expenses (Today) | Start at 25 | Start at 30 | Start at 35 | Start at 40 |
|---|---|---|---|---|
| ₹30,000 | ₹4,200/mo | ₹7,500/mo | ₹14,000/mo | ₹28,000/mo |
| ₹50,000 | ₹7,000/mo | ₹12,500/mo | ₹23,500/mo | ₹47,000/mo |
| ₹80,000 | ₹11,200/mo | ₹20,000/mo | ₹37,500/mo | ₹75,000/mo |
| ₹1,00,000 | ₹14,000/mo | ₹25,000/mo | ₹47,000/mo | ₹94,000/mo |
SIP amounts shown are approximate and assume 11% pre-retirement return, zero existing savings, and no step-up. Your actual number may be lower if you already have EPF/NPS/PPF savings.
Key Principles of Retirement Planning
Inflation is the Biggest Risk
At 6% inflation, monthly expenses of ₹50,000 today become ₹1.6 lakh in 20 years. Your corpus must generate enough to keep pace with rising costs — not just survive the first few years.
Existing Savings Matter
Your EPF, NPS, PPF, and mutual funds are already compounding. Including them in your plan shows the real gap — not the theoretical worst case — and gives you a realistic SIP target.
Healthcare Costs Skyrocket
Medical expenses grow faster in old age, at 10-14% annually. Ensure you have comprehensive health insurance and a separate healthcare buffer within your retirement corpus.
Start Early, Retire Comfortably
Starting at 25 vs 35 can reduce the required monthly SIP by 50-60% for the same retirement goal. Time in market is more powerful than any single investment decision.
Where to Park Your Retirement Corpus in India
EPF + VPF (8.15% tax-free)
Your mandatory EPF contribution compounding at 8.15% tax-free is one of the best risk-free returns available in India. Consider maxing out VPF (Voluntary Provident Fund) for additional tax-free growth — up to ₹2.5L annual contribution stays fully tax-exempt.
NPS (National Pension System)
Extra ₹50,000 deduction under Section 80CCD(1B) beyond the ₹1.5L 80C limit. Choose the aggressive lifecycle fund (75% equity) if you're under 40. NPS locks in until 60 but offers the lowest-cost equity exposure in India (0.01% fund management charge).
Equity Mutual Funds via SIP
For the growth portion of your retirement corpus, index funds (Nifty 50, Nifty Next 50) or flexi-cap funds via SIP provide the best long-term wealth creation. LTCG above ₹1.25L is taxed at 12.5% — still better than FD taxation for most people.
PPF (for the conservative bucket)
PPF's 7.1% return is fully tax-free under EEE status (exempt at investment, growth, and withdrawal). Max ₹1.5L/year. Ideal for the debt portion of your retirement plan if you're in the 30%+ tax bracket.
