About This Calculator
Retirement planning is crucial for financial security in your golden years. Our calculator helps you determine how much you need to save and invest to maintain your desired lifestyle after retirement, with region-specific defaults for India, the US, and the UK.
The calculator considers inflation, life expectancy, current savings, and expected returns to provide a comprehensive retirement plan with monthly investment requirements. It uses the 4% safe withdrawal rule (based on the Trinity Study) to compute the required corpus, then calculates monthly investments needed to reach that goal.

- Safe Withdrawal Rate: 4% rule for sustainable withdrawals (Trinity Study)
- Life Expectancy: Plans for post-retirement years
- Current Savings: Includes existing retirement corpus

Frequently Asked Questions
How much corpus do I need for retirement?
A common rule is needing 25-30 times your annual expenses at retirement. For monthly expenses of ₹50,000, you need approximately ₹1.5-2 crore corpus. This assumes 4% annual withdrawal rate. Our calculator provides precise calculations based on your specific expenses, inflation, life expectancy, and expected returns.
At what age should I start retirement planning?
Start as early as possible - ideally in your mid-20s when you start earning. Starting at 25 vs 35 can reduce your monthly investment requirement by 40-50% due to compounding. Even if you start late, begin immediately - it's never too late to start planning for retirement.
What is the 4% rule for retirement?
The 4% rule suggests you can withdraw 4% of your retirement corpus annually without depleting it over 30 years. In India, considering higher inflation (6%) and returns (8-10%), a 3.5-4% withdrawal rate is recommended. For a ₹1 crore corpus, this means monthly withdrawal of ₹35,000-40,000.
How much should I save monthly for retirement?
Save at least 15-20% of your income for retirement starting in your 20s, 20-25% in 30s, and 30-40% if starting in 40s. For a target corpus of ₹2 crore in 25 years, you need to invest approximately ₹15,000-20,000 monthly assuming 12% returns. Use our calculator to find your exact requirement.
Is 1 crore enough for retirement in India?
₹1 crore may be sufficient for modest retirement in smaller cities with monthly expenses of ₹25,000-30,000. For metro cities with expenses of ₹50,000+, you need ₹2-3 crore. In the US, the equivalent target is $1-2 million for comfortable retirement. In the UK, £500,000-£1 million is a typical target depending on lifestyle and location. The adequacy depends on your lifestyle, healthcare needs, and inflation. Our calculator helps determine the exact amount for your situation.
What retirement investment options are best?
In India: NPS (9-12% returns, tax benefits), PPF (7.1%, EEE tax status), EPF (8.25%), equity mutual funds via SIP (12-15% long-term). In the US: 401(k) with employer match, Traditional/Roth IRA, taxable brokerage accounts. In the UK: Workplace pension (auto-enrolment, minimum 8% total), SIPP, and State Pension. Diversify across equity for growth and fixed income for stability in your retirement portfolio regardless of country.
How does inflation affect retirement planning?
Inflation erodes purchasing power over time. At 6% inflation, ₹50,000 monthly expenses today will be ₹2.9 lakh in 30 years. Our calculator adjusts for inflation to show you the future value of expenses and the corpus needed to maintain your lifestyle. Always plan with realistic inflation assumptions (6-7% for India).
What life expectancy should I use for planning?
Use 80-85 years for conservative planning. With increasing life expectancy and healthcare advances, many people live into their 90s. Planning for 85 years ensures you don't outlive your savings. If you have family history of longevity, consider planning for 90 years to be extra safe.
What are the tax benefits for retirement planning?
India: Section 80C (₹1.5L deduction for PPF, ELSS, NPS, EPF), Section 80CCD(1B) (₹50K additional NPS deduction), NPS maturity (60% lump sum tax-free). US: 401(k) and Traditional IRA contributions are tax-deductible; Roth accounts offer tax-free withdrawals. UK: Pension contributions receive 20-45% tax relief at source; 25% of pension can be withdrawn tax-free lump sum. Check local tax rules for current limits.
How to calculate retirement corpus if I'm starting late?
If starting late (40s or 50s), you'll need to save more aggressively. Increase savings rate to 30-50% of income, consider delaying retirement, work part-time post-retirement, downsize lifestyle expectations, and focus on higher-return investments while managing risk. Our calculator shows required monthly investment for any starting age.
