Barry and Samantha Harris – Retirement Savings
You must work on your own spreadsheet with Excel skills or concepts.
Barry and Samantha are starting to take their retirement planning seriously. They are both 45 and plan to retire in 20 years at the age of 65. They expect to live 15 years in retirement (a life expectancy of 80). Between their 401k accounts they currently have $66,000 in retirement savings.
They currently have a combined income of $80,000 per year and expect to be able to live comfortably in retirement with 80% of their current purchasing power. They expect inflation to be 2% per year for the rest of their lives. They also expect to earn an averaged 11% per year on their investments, both now and in retirement.
What amount of annual income will they need (after adjusting for inflation) in each of the fifteen years of retirement to have the purchasing power of 80% of their current income?
Assuming they will continue to earn 11% on their investments, how much money will they need to have in their retirement accounts when they retire so that it will provide the fifteen years of income?
Taking into account what they currently have in savings, how much will they have to save each month to meet their retirement needs?
Sensitivity analysis: Redo the analysis assuming that they only earn 8% per year on their investments, instead of 11%. Determine the needed amounts so they have the money they need in retirement.
Note: Assume that all payments will be made at the end of the period (ordinary annuity).
