Q: I am 24. I want to retire at 65. I plan to live to 85. How much do I need to save every year if I want to spend $100K every year after retirement?
A:
To retire at 65, live until 85, and spend about $100,000 per year in retirement, you would need to save roughly $6,700 per year starting at age 24. That is about $560 per month. This estimate assumes your investments earn about 7% annually before retirement and about 4% during retirement, with your retirement spending measured in today’s dollars.
The estimate was calculated in two steps. First, I found how much money would be needed at age 65 to fund $100,000 of annual spending for 20 years in retirement, treating retirement withdrawals like a 20-year annuity discounted at a 4% annual return. That gave a required retirement balance of about $1.36 million. Second, I calculated the fixed annual savings needed from age 24 to 65 to grow to that amount, assuming a 7% annual investment return during the saving period.
