CPF Life: Is it a worthwhile investment?

CPF Life: Is it a worthwhile investment?

In a previous post, CPF Life: A Primer, we described the features of the CPF Life scheme. Singapore has phased out pension schemes for most of the citizens and residents. Hence, CPF Life will play an important role in post-retirement finances of the CPF members, being a mandatory annuity which serves as a cross between the defunct defined benefits pension schemes, and a the defined contribution scheme which the CPF has been associated with. But it is common to view CPF Life as an investment, and whether it is a worthwhile investment.

In particular, as a life-long annuity, it hedges the post-retirement finances of the CPF members against longevity risk, i.e. the risk of outliving financial resources. Therefore, CPF Life should be evaluated, not as an investment (i.e. what is the return on investment, when is the breakeven longevity), but rather as a hedge (i.e. does it protect against longevity risk – yes, is it actuarially fair, or value for money). In the following, we address the second metric for evaluating CPF Life – what is the value of CPF Life, and is it a worthwhile investment?

Calculating the Value of CPF Life

The assessment of the value of CPF Life is a straightforward present valuation of the cashflows:

  1. At the age of 55, the CPF member “invests” a sum of money into a deferred annuity. We assume this is the Full Retirement Sum (FRS) of members turning 55 in 2019, $176,000
  2. At the age of 65 onwards, the CPF member receives a monthly stream of payments. This is projected by the CPF Board based on various assumptions regarding the returns it achieves on the funds
  3. Should the CPF member pass on before starting to receive the monthly payments at the age of 65, the CPF Board refunds the entire FRS plus the accumulated interest to deceased member’s nominees
  4. Should the CPF member pass on after starting to receive the monthly payments at the age of 65, the CPF Board pays the projected bequest to the deceased member’s nominees. The amount of the bequest depending on the age of the member.

We need two further parameters to evaluate the value of CPF Life:

  1. The discount rate. This is derived by computing the discount rate on a stream of payments over time from the age of 65 onwards until the exhaustion of the funds in a member’s Retirement Account (RA) such that the present value is equal to the minimum sum of $176,000. This works out to be 4.27%, which is a blend of the RA interest rate, plus the extra 1% paid to balances up to $60,000 and the additional 1% paid on balances up to $30,000.
  2. The likelihood that the member will pass on at a specific age. This is derived from the preliminary Life tables for Singapore 2017

950.1803119,0543,4363.8
100+1.000005,5485,5482.6

From these tables, we can compute the likelihood of a person surviving up a particular age by dividing the Number of Survivors at exact age x by the same number at an earlier age. For example, the chance that a 55-year old male will survive to the age of 90 is:

I90/I55 = 24,137/95,636 = 25.24%

We now have the pieces to value the CPF Life Scheme for a 55 year old setting aside his/her Full Retirement Sum.

To find the present value of a future payment at the age of 90 say, P90, we discount this payment for the time until the receipt of the payment. So for a 55 year old person, the value of this payment at the age of 90 (i.e. in 35 years time) is:  

Present Value = P90 / (1 + Discount Rate)t

where t = 35 years, and Discount Rate = 4.27%. For an annuity, the payment at age 90 is only received if the person survives until age 90. Hence, we need to further adjust this by the likelihood of this payment happening, which is 25.24% for a male, as computed earlier. In the case of CPF Life, there is also a bequest payable if he/she passes away in the same year. The likelihood of this bequest being received (by the nominees, of course!) is the chance that the person survives until age 90 (which is 25.24%) and the chance that he/she then passes on in the same year q90, which is 14.73% from the life table above.

Putting things together

Let’s compute the present values for the payments in the future at different ages for a male aged 55 years today. We assume the CPF Life payment is at the higher level projected by the CPF Board. We also assume that the entire amount of the CPF Life’s payments for a particular year is paid at the start of the year. And if the person passes away in a particular year, he does so at the end of the year (so he receives both the annuity payments and the bequest).

100$53$53

If we do this for every single age starting from 55 onwards, and sum up all the present values, we arrive at the value of the CPF Life for a person aged 55 putting aside the Full Retirement Sum. What do these values look like? These are below:

For Males:

Full Retirement Sum Plan
$176,000
Present Value at Age 55% Value form Monthly Payments% Value from Bequest
Standard$163,244 - $178,41682.4%17.6%
Basic$173,267 - $188,75370.7%29.3%
Escalating$148,482 - $174,44880.2%19.8%

For Females:

Full Retirement Sum Plan
$176,000
Present Value at Age 55% Value form Monthly Payments% Value from Bequest
Standard$160,954 - $177,46989.1%10.9%
Basic$170.598 - $187,22679.6%20.4%
Escalating$155,082 - $172,40087.2%12.8%

Now, these values are the average values to the entire cohort of males and females under the CPF Life scheme. They can be very different for each individual, depending on when the person passed away. A longer-lived person would get more benefit and value than a shorter-lived one, as is the nature of annuities and longevity risk pooling. The tables following provide another view of the present value of the CPF Life Plans, depending on how long the person survived:

85$166,467 - $184,750$164,702 - $182,710$157,936 - $177,024
90$182,443 - $202,481$172,214 - $191,411$179,249 - $200,911

What can we conclude?

What do these values for the tell us? Is CPF Life a worthwhile investment? There are a number of conclusions:

  1. We need to see if the inaugural cohort in the CPF Life scheme gets the higher payout projected. Only at this higher level of payouts is the CPF Life Scheme worth the Full Retirement Sum. In other words, if the payouts under CPF Life are less, the CPF Board has replaced the Retirement Sum Scheme with something that is of lesser value in practice.
  2. A significant amount of the value of CPF Life is for bequests, which diminish over time. In the worst case, the bequest disappears exactly when a CPF member passes away, leaving little or nothing to his/her loved ones. So even while the Basic Plan has a higher present value compared to the Standard or Escalating Plans, the additional value comes form the bequests which may not be paid out ultimately.
  3. In an annuity scheme, those who live the longest gain the most. In the case of CPF Life, it is the lucky 50% who live past their life expectancy who will gain. Therefore, CPF members in poor health before the age of 65 (which could reduce life expectancy by 3 years or more), should choose a Plan which maximizes the value to them and their loved ones given their expected lifespans.

These conclusions should not detract from the fact that the CPF Life scheme is a valuable addition to the retirement planning tools and products, which have been lacking in many aspects previously, available for CPF members. However, there is still room to improve in terms of product design, communication, and understanding of the CPF Life Scheme for the benefit of CPF members. It is in this spirit that we present these conclusions.
