Retirement Planning and Pension Systems
This domain tests retirement needs analysis, accumulation and withdrawal math, pension plan types, social insurance, annuities, inflation, longevity, sequence-of-returns risk, and retirement tax issues. Questions often ask whether a client is on track, how much to save, and how pension or annuity income changes the gap.
Core rules and concepts
- Retirement need is usually expressed as a replacement ratio of pre-retirement income, then adjusted for inflation and expected retirement expenses. A lower replacement ratio may suffice if debts are retired and work expenses disappear.
- Defined-benefit plans promise a benefit, usually based on salary and service; the employer bears investment and longevity risk. Defined-contribution plans provide an account balance; the employee bears investment and longevity risk.
- Accumulation math: future value of current savings plus future value of contributions. Withdrawal math: required capital equals annual need divided by a sustainable withdrawal rate, or is computed as a present value of an annuity.
- The 4% withdrawal rule is a heuristic, not a guarantee. Dynamic spending, guardrails, and bucketing can reduce sequence risk, which is the danger of poor returns early in retirement.
- Longevity, health care, long-term care, and inflation are the main risks. Annuities can insure longevity through mortality credits but carry fees and credit risk.
- Tax-deferred accounts reduce current tax but create required minimum distributions and ordinary-income taxation later. Withdrawal order should coordinate tax brackets, capital gains, and estate goals.
Worked example
A 40-year-old needs 50,000 of annual spending in today's dollars at age 65. With 2.5% inflation, the future need is 50,000(1.025^25) = about 92,700. At a 4% initial withdrawal rate, required capital is 92,700 / 0.04 = 2,317,500. Current savings of 250,000 at 6% grow to 250,000(1.06^25) = about 1,073,000, leaving a gap of 1,244,500. The annuity factor for 25 years at 6% is about 54.86, so annual savings needed are 1,244,500 / 54.86 = about 22,700. Reasoning: the gap is closed with level annual contributions; monthly saving would be slightly different, and a review should test lower returns and higher inflation.
Traps that cost marks
- Ignoring inflation or mixing real and nominal figures.
- Treating the 4% rule as guaranteed.
- Ignoring sequence-of-returns risk.
- Underestimating longevity and health-care costs.
- Forgetting early-withdrawal penalties and RMDs.
- Assuming a pension is fully vested or inflation-indexed.
