Systematic Unit Redemption
Also written SUR · Systematic Unit Redemption (SUR) · SUR Equal Units
An NPS exit mode that redeems a fixed number of units every period over the chosen drawdown period — minimum six years — so the rupee payout moves with the NAV.
In plain language
Instead of taking an NPS lump sum in one go, a subscriber can sell it down in equal slices of units. That is Systematic Unit Redemption (SUR).
The number of units redeemed each period is fixed at the start. The rupees received are not: each payout is those units multiplied by the NAV on the day. When the NAV is up, the payout is larger; when it is down, smaller.
SUR was introduced by the PFRDA (Exits and Withdrawals under NPS) (Amendment) Regulations, 2025, as an additional mode of exit, with a withdrawal period of at least six years.
How it works
Two places SUR appears.
| Context | Role |
|---|---|
| Exit regulations | An approved systematic withdrawal option, alongside SLW, for the lump-sum portion — and for part of the corpus-based options |
| RIS drawdown (May 2026) | Option (b), SUR — Equal Units, one of two drawdown methods; SPR is the default |
The six-year rule in the corpus bands. On normal exit, where accumulated pension wealth is more than Rs 8 lakh and up to Rs 12 lakh, the subscriber may withdraw up to Rs 6 lakh as lump sum and use the balance for annuity or through SUR for a minimum period of six years. This applies in both the Government and Non-Government exit rules.
Equal Units under the RIS. The total unit balance is liquidated in equal instalments over the selected drawdown period; units from each asset class are redeemed in proportion to the corpus held in it. The drawdown can run up to age 85.
The formula
Units per period = Total units at start ÷ (Drawdown period × Payout frequency)
Rupee payout = Units per period × NAV on the redemption date
A worked example
The workbook's example. A subscriber with a Rs 80 lakh corpus — 8,00,000 units at an NAV of Rs 10 — exits at 60 with a 25-year drawdown period and monthly payouts.
Units per month = 8,00,000 ÷ (25 × 12) = 8,00,000 ÷ 300 = 2,666.67 units
That unit count never changes. The rupees do (NAVs below are illustrative):
| Month | NAV | Payout |
|---|---|---|
| A | Rs 10 | 2,666.67 × 10 = Rs 26,667 |
| B | Rs 11 | 2,666.67 × 11 = Rs 29,333 |
| C | Rs 9 | 2,666.67 × 9 = Rs 24,000 |
The corpus-band case. A Non-Government subscriber exits with Rs 10,00,000. It falls in the Rs 8 lakh to Rs 12 lakh band:
Lump sum (maximum) = Rs 6,00,000
Balance = Rs 4,00,000 → annuity, or SUR over at least 6 years
If she picks SUR over exactly six years with monthly payouts, the balance is redeemed over 72 instalments — or she may follow the standard route of up to 80 per cent lump sum and at least 20 per cent annuity instead.
Why NISM asks about it
Chapter 4, section 4.2.4, introduces SUR as an exit mode under the 2025 amendment, applies it in the Rs 8 lakh to Rs 12 lakh corpus band for both sectors, and defines SUR — Equal Units as drawdown option (b) with its formula and the Rs 80 lakh worked example. Chapter 9 repeats the corpus-band rules in the Exits and Withdrawals Regulations. Expect the units-per-period calculation and the six-year minimum.
Common exam traps
- SUR fixes units, not rupees. The payout changes with every NAV.
- Six years is a minimum, and it is attached to the Rs 8 lakh to Rs 12 lakh band, where the balance after a Rs 6 lakh lump sum goes to annuity or SUR.
- SUR is not the default drawdown method — SPR is.
- 2,666.67 units, not Rs 2,666.67. The worked example is a unit count.
- Multiply the drawdown years by the payout frequency before dividing: 25 × 12 = 300.
- SUR is not SLW. Both are approved systematic withdrawal options named together in the workbook; only SUR has the equal-units definition and the six-year minimum.

1.A subscriber to the NPS receives the pension for income in retirement from:
- a)An annuity purchased on retirement
- b)The corporate employer
- c)PFRDA
- d)The government
Show the answer
Answer: (a) An annuity purchased on retirement
This is the workbook sample question. At retirement the subscriber draws the corpus so created TO BUY AN ANNUITY THAT WILL PROVIDE REGULAR INCOME IN RETIREMENT.
The annuity is issued by an Annuity Service Provider — one of 15 IRDAI-regulated life insurance companies empanelled by PFRDA. PFRDA regulates but pays no pension; the employer contributes during service but pays nothing after; the government contributes 14% for its own employees but does not pay the pension.
⚠️ Two places where a guarantee does come from the government are worth keeping separate in your mind: in the Atal Pension Yojana, the pension is guaranteed by the Government of India; and the Unified Pension Scheme carries an assured payout of 50% of the last 12 months' average basic pay. Neither is how a standard NPS pension arises.
2.Under the Systematic Payout Rate drawdown method, a subscriber exits at 60 with a Drawdown End Age of 85. What is his SPR at 60, how does it change, and what is reset annually?
- a)A constant 4.00% throughout, with nothing reset
- b)4.00% at 60, rising progressively to 100% at 84; both the rate and the amount are reset on his birthday using the prevailing market value of the drawdown corpus
- c)3.50% at 60, falling as the corpus depletes
- d)100% at 60, since the whole corpus is available immediately
Show the answer
Answer: (b) 4.00% at 60, rising progressively to 100% at 84; both the rate and the amount are reset on his birthday using the prevailing market value of the drawdown corpus
The formula: ⚠️ SPR at Current Age = 1 ÷ (Drawdown End Age − Current Age) %
At 60: 1 ÷ (85 − 60) = 1/25 = 4.00%. At 84: 1 ÷ (85 − 84) = 100%. The workbook confirms — the SPR at age 60 is 4.00%, RISING PROGRESSIVELY TO 100% AT AGE 84.
The rate rises every year because the remaining period shrinks. By construction the corpus is drawn to exhaustion at the end age.
Payout per period = (SPR ÷ Payout Frequency) × Market Value of Drawdown Corpus, and ⚠️ "the payout rate and payout amount are RESET ANNUALLY ON THE SUBSCRIBER'S BIRTHDAY, based on the PREVAILING MARKET VALUE... BETWEEN TWO BIRTHDAYS, THE SUBSCRIBER RECEIVES CONSTANT PERIODIC PAYOUTS."
Contrast SUR Equal Units: units are fixed at the start (Total Units ÷ (Drawdown Period × Frequency)) and the actual rupee payout varies each month depending on the NAV. SPR fixes rupees for a year and varies units; SUR fixes units and varies rupees.
⚠️ And crucially, drawdown has NO IMPACT ON THE MANDATORY ANNUITISATION REQUIREMENT of 20% or 40% — it phases only the lump-sum portion.
3.Which of these expenses are likely to be higher in retirement?
- a)Housing
- b)Transportation
- c)Personal needs
- d)Health related expenses
Show the answer
Answer: (d) Health related expenses
This is the workbook sample question, and one sentence answers it: the level of expense may go down in some categories LIKE TRANSPORTATION AND PERSONAL UPKEEP, while it may go up in other categories SUCH AS LEISURE AND HEALTH.
That disposes of options (b) and (c) directly. Housing is not listed as rising, and the workbook expects mortgages and other large debt obligations to be paid off before retirement.
Health is flagged twice more in the chapter: it is the expense most likely to be underestimated, and health costs and travel typically increase at a HIGHER RATE than standard inflation.
