Retirement Planning and Pension Arrangements
Domain overview
Retirement planning and pension arrangements tests retirement needs analysis, pension plan types, contribution and vesting rules, and withdrawal planning. Questions often require you to convert today's spending into a future income need and then into a capital target.
Pension arrangements
Defined benefit (DB) plans promise a formula-based benefit, typically linked to salary and service; the employer bears investment risk. Defined contribution (DC) plans provide an account balance; the employee bears investment risk. Vesting determines ownership of employer contributions. Know the difference between accumulation and decumulation, and the role of state or social security benefits.
Building the projection
Estimate replacement income, adjust for inflation, subtract guaranteed income, and apply a sustainable withdrawal assumption. Test longevity and healthcare costs. A lower withdrawal rate preserves capital longer but requires more savings.
Worked example
A client needs $40,000 per year in today's dollars at retirement in 25 years. At 3% inflation, the future need is $40,000 × 1.03^25 = $83,751. Using a 4% initial withdrawal rate, required capital is $83,751 ÷ 0.04 = $2,093,775. If guaranteed pension income covers $30,000 of that annual need, the portfolio only needs to fund $53,751, or $1,343,775 at 4%. The reasoning separates inflation, income replacement, and guaranteed income.
Traps that cost marks
- Projecting in today's dollars but withdrawing in future dollars.
- Ignoring inflation or longevity.
- Assuming a DB benefit is secure without considering plan funding.
- Using an average return with no volatility or sequence risk.
