The client has an income need of €30,000 per year and an expected pension of €20,000 per year, creating a shortfall of €10,000 per year in today’s money. Because retirement is in 10 years and inflation is expected to average 2% over that period, the annual shortfall must be inflated to the amount required at the start of retirement. The inflated shortfall is calculated as €10,000 × 1.02^10, which equals approximately €12,189.94. The question then asks for the lump sum required to fund retirement assuming the investments earn 4% per year. In this style of exam question, the lump sum at retirement is typically calculated as a perpetuity that can generate the required annual amount from investment returns, using Lump sum = Required annual income ÷ expected return. Therefore, €12,189.94 ÷ 0.04 ≈ €304,748.5, which rounds to €304,749. A common trap is choosing €250,000, which is €10,000 ÷ 4% and ignores inflation over the next 10 years.
