GSP110 Introduction to Personal Financial Planning ECA July 2026 SUSS Assignment Sample Singapore

For information and reference only – not to be submitted as your own work.

This extract shows how a strong answer can be built for the SUSS GSP110 Introduction to Personal Financial Planning End-of-Course Assessment (ECA) in the July 2026 semester. It covers one retirement calculation (Question 1b), one savings-goal calculation (Question 2a) and short model points for the mortgage servicing ratio (Question 3a) and Supplementary Retirement Scheme withdrawals (Question 4c). Your own inputs, assumptions and wording must replace everything here.

The original assessment brief is available on our question page: GSP110 Introduction to Personal Financial Planning ECA July 2026: Poly-Crisis Retirement and Housing Plan.

The full brief is not reproduced. If you want the wider set of GSP110 questions we have on file, see the Singapore assignment questions library, and the related GSP110 tutor-marked assignment question. A step-by-step strategy guide sits in our GSP110 ECA approach blog.

Question 1(b): Retirement income calculation (illustrative inputs)

Important: the figures below are illustrative only. The real question asks you to supply your own age, required income, inflation rate and post-retirement return, and to justify them. Do not copy these numbers.

Illustrative assumptions

The payment period is counted as ages 67 to 91 inclusive plus the age-92 payment, giving 26 start-of-year withdrawals. State your own counting convention so the marker can follow it.

Step 1: Future value of the first year’s income at 67

The income need rises with inflation until the first withdrawal. Formula: FV = PV × (1 + g)ⁿ.

FV = 40,000 × (1.03)³⁷ = 40,000 × 2.9852 = S$119,409 (rounded).

Step 2: Net interest rate for the withdrawal period

Because withdrawals keep growing with inflation while the fund earns a nominal return, use the real (net) rate: i* = (1 + r) ÷ (1 + g) − 1.

i* = 1.05 ÷ 1.03 − 1 = 1.9417% a year.

Step 3: Lump sum needed at 67 (annuity due)

Withdrawals are taken at the start of each year, so use the present value of an annuity due: PV = PMT × [1 − (1 + i*)^−N] ÷ i* × (1 + i*).

As a check, discounting each growing withdrawal at 5% and summing all 26 gives the same S$2,466,708.

Why annuity due, and what changes with the wrong choice

Income is needed at the start of each year to live on, so the first withdrawal happens on the retirement date. Treating it as an ordinary annuity would give S$2,419,724 (119,409 × 20.2642), which is about S$46,985 too low. That shortfall is the common error markers look for.

A single sentence in the answer should link the choice to the cash-flow timing: payments at the beginning of each period, so each one earns one fewer year of return.

Question 2(a): Annual contribution for a down payment

The scenario: a 32-year-old wants a cash down payment of S$400,000 in 15 years, has S$50,000 now, expects inflation of 3.5% and a unit-trust return of 7.5%. Contributions are made at the start of each year.

Decision: is S$400,000 in today’s dollars?

The brief gives an inflation rate, and an inflation rate has no role if the target is already a future amount. The better reading is that S$400,000 is today’s price, so the goal is inflated first. We state this assumption openly and show the other reading for comparison.

Working for Reading A

Formula (future value of an annuity due): FV = PMT × [((1 + r)ⁿ − 1) ÷ r] × (1 + r).

1. Inflated goal: (1.035)¹⁵ = 1.67535, so 400,000 × 1.67535 = S$670,140.
2. Growth of the existing S$50,000: (1.075)¹⁵ = 2.95888, so 50,000 × 2.95888 = S$147,944.
3. Amount the new savings must produce: 670,140 − 147,944 = S$522,196.
4. Annuity-due factor: ((2.95888 − 1) ÷ 0.075) × 1.075 = 26.1184 × 1.075 = 28.0772.
5. PMT = 522,196 ÷ 28.0772 = S$18,599 at the start of each year (about S$1,550 a month).

Check: S$18,599 deposited at the start of each of 15 years at 7.5%, plus the S$50,000 lump sum, accumulates to S$670,140.

If the contributions were wrongly treated as end-of-year payments, the answer would be S$19,993, which overstates the need. Note also that a 7.5% unit-trust return is an expectation, not a guarantee, and your answer should say so.

Question 3(a)(ii): Mortgage Servicing Ratio (model points)

• Definition: the MSR compares monthly property-loan repayments with gross monthly income. The Monetary Authority of Singapore (MAS) caps it at 30% for HDB flats and executive condominiums bought with a loan.
• Formula: MSR = monthly mortgage repayment ÷ gross monthly household income × 100.
• Illustrative use: on a combined income of S$8,000, the repayment ceiling is S$2,400 a month (30%).
• Significance: it limits borrowing so that housing debt does not squeeze the budget, protects against house-poor outcomes, and leaves room for emergency savings and retirement contributions.
• Link to the case: in a high-inflation period, other costs rise while the repayment is fixed or tied to rates, so a buyer close to the cap has little buffer.

The Enhanced CPF Housing Grant for eligible first-timer families can reach S$120,000 and is income-tested (household income ceiling of S$9,000 a month at the time of checking). It reduces the loan needed and so eases the MSR, but confirm the latest figures yourself before quoting them.

Question 4(c): SRS withdrawals (model points)

• Penalty-free age: the age is the statutory retirement age prevailing when the first SRS contribution was made.
• Tax at that age: only 50% of each withdrawal is taxable income.
• Spreading: withdrawals can be made over up to 10 years from the first penalty-free withdrawal.
• Early withdrawal: the full amount is taxable and a 5% penalty applies, apart from limited exceptions such as medical grounds.
• Tax benefit of spreading: Singapore uses progressive resident tax rates, so a smaller annual taxable amount stays in lower bands. Illustratively, S$400,000 taken in one year leaves S$200,000 taxable at high marginal rates; S$40,000 a year for 10 years leaves S$20,000 taxable annually, which sits in the lowest band.

Show a short two-column comparison of lump sum versus 10-year plan in your answer and name the assumption that other income is low in retirement.
