How professional retirement planning works
1) Grow today's expenses by inflation until retirement — that is the income you will actually need. 2) Calculate the corpus whose real return (return minus inflation) funds that income for your whole retirement. 3) Compare that corpus with the projected value of your current savings plus monthly contributions. The difference is your shortfall or surplus.

Retirement Calculator — build your retirement plan like a professional
This professional retirement calculator projects your savings at retirement, the inflation-adjusted corpus you will actually need, your monthly income, and the shortfall or surplus of your current plan. It uses the real (inflation-adjusted) return method used by financial planners — not a rough guess.
The professional method explained
Step 1: grow today's annual expenses by inflation until retirement to find future expenses.
Step 2: calculate the corpus needed to fund those expenses for life — using real return as the annuity factor over your retirement period.
Step 3: project what your current savings and monthly contributions will grow to at your expected return.
Step 4: subtract. The difference is your shortfall (or surplus).
The 4% rule and why it's just a shortcut
The 4% rule (corpus = 25× annual expenses) comes from US data and assumes a 30-year retirement with a balanced portfolio.
In India, with 6% inflation and longer retirements, a safer planning band is 3–3.5% or a corpus of 28–33× expenses.
This calculator is more precise because it uses your actual age, retirement age, life expectancy and real return.
How much should you save?
The 15% rule: start saving 15% of gross income in your 20s for a comfortable retirement at 60.
Start at 35? You may need 25–30%. Start at 45? 40%+ or a delayed retirement.
Tax-advantaged accounts (PPF, NPS, EPF) should be maxed first because the compounding inside is tax-free.
How to use this calculator
- Enter your current age and planned retirement age.
- Set your life expectancy (use 85 if unsure).
- Enter current annual expenses and current retirement savings.
- Add your monthly contribution and expected return before tax.
- Enter the inflation rate and read your corpus, shortfall and monthly income.
Pro tips
- Use a conservative expected return of 7–8% and inflation of 5–6% for India.
- Rebalance annually: shift 5% from equity to debt each 5 years as retirement nears.
- Include NPS and PPF in the 'monthly contribution' along with mutual fund SIPs.
