About Retirement Planning on Utilia

Retirement planning spans two phases: accumulation (building savings) and decumulation (spending them down strategically). Most people focus almost entirely on the first phase and underestimate the complexity of the second. How much you withdraw, when you claim Social Security, how you manage RMDs, and how you allocate your portfolio in retirement can make a difference of hundreds of thousands of dollars over a 20–30 year retirement.
