Retirement Planning Basics for NISM certification
Retirement is the biggest and longest goal anyone plans for, and the only one that can't be funded with a loan. This chapter explains why retirement needs early planning, the steps in working out the income and corpus required, how inflation and returns pull in opposite directions, the replacement ratio and expense methods, and how employer superannuation schemes work. Tax references follow the Income-tax Act, 2025 as given in the NISM X-B workbook (Sept 2026 version); worked figures were checked by calculation.

Key formulas
| Future cost | Today's cost × (1 + inflation)^years |
|---|---|
| Real (inflation-adjusted) rate | (1 + return) ÷ (1 + inflation) − 1 |
| Corpus at retirement | PV of the first year's expense, growing with inflation, for the years in retirement, at the real rate (payments at the start of each year) |
| Replacement income, year 1 | Pre-retirement income × replacement ratio |
| Each later year | Previous year's income × (1 + inflation) |
Concepts explained
Retirement corpus
The retirement corpus is the sum needed at retirement to fund rising expenses for all the years in retirement.
What it means
- Grow today's expenses to retirement with inflation.
- Discount the rising expense stream at the real rate for the years in retirement.
- Then work out the SIP or lump sum needed to build it.
- ₹50,000 a month today → ₹2,14,594 at 60 (6%, 25 years)
- Annual ≈ ₹25,75,122; real rate 1.89%; 25 years
- PV at start of each year
Answer: Corpus ≈ ₹5.19 crore; SIP ≈ ₹39,100 a month at 10%
Related terms
- Longevity risk: living longer than the corpus lasts
- Real rate: (1 + return) ÷ (1 + inflation) − 1
Exam tip: Higher inflation or a longer retirement increases the corpus; a higher return reduces it.
Replacement ratio method
Retirement income in year 1 is a fixed percentage of pre-retirement income, then rises with inflation.
What it means
- Common ratios are 70–80%.
- Below 100% because loan EMIs, school fees, work costs and taxes fall.
- Less accurate the further away retirement is.
- ₹80,000 a month growing 8% for 15 years → ₹2,53,774
- 70% → ₹1,77,641 in year 1
- × 1.06 → ₹1,88,300 in year 2
Answer: Income target rises with inflation each year

- Expense protection method: builds the target from a retirement budget instead
Inflation and the real rate in retirement
Inflation raises the money needed; returns reduce it; the real rate combines the two.
What it means
- At 6%, ₹100 today costs ₹179 in 10 years, ₹321 in 20 and ₹574 in 30.
- Expenses keep rising during retirement too.
- Health and travel costs often rise faster than general inflation.
- Return 8%, inflation 6%
- 1.08 ÷ 1.06 − 1
Answer: ≈ 1.89%

Approved superannuation fund
An employer pension trust approved under the Income-tax Act, so contributions are deductible and the fund's income is tax-free.
What it means
- Irrevocable trust; 90% of employees in India; employer contributes; benefits payable in India.
- Sole purpose: annuities on retirement, incapacity or for dependants.
- Annuities bought from an IRDAI-registered life insurer.
- Company pays pensions from yearly profits
- No fund, no accrual provision
Answer: Pay-as-you-go fails AS 15 and exposes pensioners to the employer's fortunes
Related terms
- AS 15: ICAI standard requiring accrual of retirement benefits
- Section 2(11), Insurance Act: superannuation annuities are life insurance business
Memory tricks
No lender funds retirement, so it must be saved for, unlike education, home or car goals.
At 6%, ₹100 grows to about ₹179, ₹321 and ₹574 after 10, 20 and 30 years.
Real rate = (1 + return) ÷ (1 + inflation) − 1.
Approval needs an irrevocable trust, at least 90% employees in India, annuities as sole purpose, employer contributions and benefits payable in India.
Replacement ratio uses a percentage of pre-retirement income; expense protection builds a retirement budget.
Try 3 NISM-style questions
Q1. Other things being equal, a higher expected return on the retirement corpus
- Increases the corpus needed
- Has no effect on the corpus, which depends only on expenses and inflation
- Removes the need to consider inflation at any stage of the plan
- Reduces the corpus and savings needed, but usually with more risk
Show answer
Answer: (4) Reduces the corpus and savings needed, but usually with more risk
Higher returns reduce what has to be saved, but come with higher risk, which retirees can bear less.
Q2. The expense protection method estimates retirement income by
- Taking a fixed percentage of the last salary drawn before retirement
- Adjusting a detailed current budget for costs that rise or fall in retirement
- Using the HLV of the earner
- Applying the replacement ratio to the current monthly expenses of the family
Show answer
Answer: (2) Adjusting a detailed current budget for costs that rise or fall in retirement
It builds a retirement budget: add medical, travel, gifting, maintenance; remove EMIs, school fees, taxes.
Q3. Rekha invests ₹10,000 a month from age 30 to 60; her brother invests the same from 40 to 60. At 10% a year, Rekha's corpus is about ₹2.26 crore and her brother's about ₹76 lakh. This shows
- Investing for 20 years always beats investing for 30 years at the same rate
- Both corpuses are equal once inflation over the period is considered
- Starting early has a far bigger effect than the extra amount invested
- SIPs don't benefit from compounding
Show answer
Answer: (3) Starting early has a far bigger effect than the extra amount invested
Ten extra years (only ₹12 lakh more invested) nearly triples the corpus thanks to compounding.
