Pre-Retirement Growth
Higher returns expected from equity-heavy portfolio during accumulation phase
Post-Retirement Growth
Conservative returns from debt-heavy portfolio for capital preservation
Inflation Impact
Your expenses will grow with inflation over time, eroding purchasing power
Future Expense = Current × (1 + inflation)^years
Corpus = Expense × ((1 - (1+r)^-n) / r)
Where r = real return rate (post-retirement return adjusted for inflation) and n = retirement duration in years

What is Retirement Planning?
Retirement planning is the process of determining your retirement income goals and the actions necessary to achieve those goals. It involves identifying sources of income, estimating expenses, implementing a savings program, and managing assets and risk. The earlier you start planning, the more time your money has to grow through the power of compound interest.
How is Retirement Corpus Calculated?
The retirement corpus is calculated based on your expected expenses at retirement, adjusted for inflation, and the duration you need those funds to last. The calculator uses the present value of annuity formula to determine how much you need at retirement to sustain your lifestyle. It considers both the growth of your expenses due to inflation and the returns you can earn on your corpus post-retirement.
Key Factors Affecting Retirement Planning
Several factors influence your retirement plan:
- Time Horizon: The number of years until retirement significantly impacts how much you need to save monthly
- Inflation Rate: Even moderate inflation can dramatically increase your future expenses over decades
- Expected Returns: Higher returns during accumulation phase can reduce required monthly savings
- Life Expectancy: Planning for a longer retirement ensures you don't outlive your savings
- Lifestyle Expenses: Your current and expected lifestyle determines the corpus needed
The 4% Rule Explained
A popular retirement guideline is the 4% rule, which suggests you can withdraw 4% of your retirement corpus annually (adjusted for inflation) without running out of money over a 30-year retirement. For example, if you have a corpus of $1,000,000, you could withdraw $40,000 in the first year. However, this rule has limitations and may need adjustment based on market conditions, personal circumstances, and your specific retirement duration.
Tips for Successful Retirement Planning
- Start Early: Even small contributions in your 20s can grow significantly due to compound interest
- Maximize Tax-Advantaged Accounts: Use 401(k), IRA, or equivalent accounts in your country for tax benefits
- Diversify Investments: Spread your investments across different asset classes to manage risk
- Review Regularly: Reassess your retirement plan annually and adjust contributions as needed
- Consider Healthcare Costs: Factor in rising healthcare expenses, especially in later years
- Plan for Contingencies: Maintain an emergency fund separate from retirement savings
- Reduce Debt: Aim to enter retirement debt-free, especially high-interest debt
Retirement planning is the process of determining retirement income goals and the actions necessary to achieve those goals. It includes identifying sources of income, estimating expenses, implementing a savings program, and managing assets and risk. The earlier you start planning, the more time your money has to grow through compound interest, making it easier to reach your retirement goals.
A comprehensive retirement plan accounts for inflation, expected investment returns, life expectancy, and your desired lifestyle in retirement. The goal is to accumulate enough wealth (your retirement corpus) to sustain your living expenses throughout your retirement years without depleting your savings prematurely.
Enter your current age, desired retirement age, and life expectancy to establish your planning timeline. Input your current monthly expenses — the calculator will adjust these for inflation to project what you will need at retirement. Provide your current savings and planned monthly contributions (SIP) to see how your wealth will grow over time.
Adjust the expected return rates for both pre-retirement (accumulation phase) and post-retirement (distribution phase). Pre-retirement returns are typically higher as you can afford more risk, while post-retirement investments are usually more conservative. The calculator will show whether you are on track to meet your retirement goals or if adjustments are needed.
Inflation erodes purchasing power over time, meaning that the same amount of money will buy fewer goods and services in the future. If your current monthly expenses are $5,000 and inflation averages 6% annually, you will need approximately $16,000 per month in 20 years to maintain the same lifestyle. This is why retirement planning must account for inflation-adjusted expenses.
Investment returns help combat inflation by growing your savings faster than prices rise. A diversified portfolio historically returns 8–12% annually over long periods, though with significant year-to-year variation. The difference between your expected return and inflation rate is your "real return" — the actual growth in purchasing power. Conservative estimates help ensure you do not fall short of your goals.
