Retirement Calculator
📜 Retirement modelling assumptions
The corpus model uses inflation-adjusted future value and the 4%-style sustainable-withdrawal heuristic from the Trinity study literature, applied conservatively for Indian inflation. Returns are assumptions, not guarantees — stress-test with lower rates before deciding. Last verified: June 2026.

How Much Do You Need to Retire?
The 4% rule suggests saving 25 times your annual expenses. This calculator projects your savings growth to your target retirement age. See also: the NPS Calculator and the 401K Calculator.
Reading your retirement estimate
Retirement planning depends heavily on assumptions. Inflation, investment returns, lifestyle changes, healthcare costs, and job changes can all affect the final number. Treat this result as a planning range, not as a guaranteed target.
How can you apply these results practically?
The Retirement Calculator is built for people who want a fast answer without losing context. It keeps the calculation simple, shows the result clearly, and helps you understand what the number means before you use it in a real decision.
Investment and interest calculators make long-term numbers easier to compare. Small changes in time, contribution amount, rate, or compounding frequency can create large differences over many years.
How to calculate the retirement corpus you need
Estimating the right retirement corpus requires answering three questions: How much will I spend per month in retirement? How long will I live in retirement? What return will my corpus generate during retirement? The interaction of these three variables determines whether a corpus will last or run out.
Step 1 — Estimate monthly expenses at retirement (in today's money): Start with your current monthly expenses and remove work-related costs (commuting, professional clothing, lunches out). Add healthcare (which typically increases significantly in retirement). A common estimate: 70–80% of pre-retirement monthly expenses.
Step 2 — Adjust for inflation to find future value: At 6% annual inflation, $60,000/month today = $60,000 × (1.06)^25 = $257,163/month in 25 years
Step 3 — Apply the 4% withdrawal rule: A corpus of 25× your annual retirement expenses can sustain 4% withdrawals indefinitely (assuming a balanced portfolio generating ~7% nominal with ~3% real return). Required corpus = $257,163 × 12 ÷ 0.04 = $77,100,000
How much to save monthly to reach your target
Once the target corpus is known, the required monthly monthly investment can be calculated using the future value of annuity formula at your expected investment return.
For $77,100,000 in 25 years at 12% CAGR (equity mutual fund historical average):
Monthly monthly investment = 7,71,00,000 ÷ [((1.01)^300 – 1) ÷ 0.01] = 7,71,00,000 ÷ 1,878.85 = approximately $41,037/month
Starting 10 years earlier (35 years instead of 25 years to retirement) at the same 12% CAGR would reduce the required monthly monthly investment to approximately $19,800 — less than half — due to the compounding advantage of an extra decade.
The three pillars of global retirement savings
- employer retirement fund (Employee Provident Fund): Mandatory for employees earning below $15,000 basic; both employee and employer contribute 12% of basic salary. Current interest: 8.25% p.a. Tax-free on withdrawal after 5 years of continuous service. Track your balance at unifiedportal-mem.epfindia.gov.in.
- pension fund: Government-backed scheme with equity exposure up to 75%. Contributions qualify for retirement/savings deductionCD(1) (within 80C limit) and retirement/savings deductionCD(1B) (additional $50,000 deduction). At retirement (age 60), up to 60% of corpus can be withdrawn tax-free; the remaining 40% must purchase an annuity.
- Equity Mutual Funds via monthly investment: The highest potential return vehicle for the growth phase of retirement savings. Index funds (Nifty 50, Nifty 500) provide diversification at low cost. tax-saving mutual fund funds provide retirement/savings deduction benefits with a 3-year lock-in.
Retirement savings benchmarks by age
- By age 30: Aim for 1× annual salary in retirement savings
- By age 35: 2× annual salary
- By age 40: 3× annual salary
- By age 45: 5× annual salary
- By age 50: 7× annual salary
- By age 55: 9× annual salary
- By retirement (60): 12–15× annual salary
The 4% withdrawal rule explained
The 4% rule (Bengen, 1994): withdraw 4% of your retirement corpus in Year 1, then adjust for inflation each year. Research shows this sustains a portfolio for 30+ years across historical market conditions. For India: 5–6% withdrawal may be sustainable due to higher equity returns (12–14% vs 10% US) but also higher inflation (6–7% vs 2–3%). Plan conservatively at 4% — extra corpus is never a problem.
Traditional EPF/NPS vs equity investment for retirement in India
EPF earns 8.25% (FY2024-25), tax-free, government-guaranteed. NPS offers 9–12% historically with tax benefits under 80CCD. Equity mutual funds: 12–14% CAGR historically but market risk. Optimal Indian retirement strategy: EPF + voluntary PF for guaranteed base, NPS for additional tax-advantaged equity exposure, and SIP in diversified equity funds for the remaining retirement corpus. Never put all retirement savings in FDs — inflation erodes purchasing power over 25–30 years.
When to start — the compounding cost of delay
Starting at 25 vs 35 with $500/month at 12% return: age 25 start = $3,247,635 at 60. Age 35 start = $948,818 at 60 — only 29% as much. Each decade of delay reduces the final corpus by 65–70%. If you are over 40, your only lever is increasing the monthly investment amount — typically 3–5× what a 25-year-old would need to accumulate the same retirement corpus.

Frequently asked questions about retirement planning
Is $10,000,000 enough to retire? At 4% withdrawal rate, $10,000,000 generates $400,000 per year ($33,333/month) in year one. With inflation, this purchasing power erodes over time. For most urban middle-class families, $10,000,000 is insufficient. A minimum of $3–5 million (×10) is a more realistic target for comfortable retirement in a tier-1 city.
When should I shift from equity to debt as retirement approaches? The standard approach is gradual rebalancing — reducing equity allocation from 70–80% in the accumulation phase to 40–50% as retirement approaches (5–10 years before) and 30–40% in early retirement. This reduces sequence-of-returns risk (the danger of a market crash just before or after retirement).
What is the safe withdrawal rate for global retirees? The 4% rule is based on US market data. For global retirees with a portfolio in rupees subject to global inflation (typically 5–7%), a withdrawal rate of 3–3.5% is more conservative and sustainable over a 30-year retirement horizon.
