Retirement Calculator (Nest Egg Target & 4% Safe Withdrawal)
Calculate your retirement nest egg goal, required savings rate, and projected retirement income.
TL;DR: Retirement Calculator determines your total required retirement savings nest egg based on expected annual spending, the 4% safe withdrawal rule, and inflation.
How Much Money Do You Need to Retire and What Is the 4% Rule?
Under the Trinity Study's 4% Rule, you need an investment nest egg equal to 25 times your desired annual retirement spending (e.g., spending $60,000/year requires a $1.5 million nest egg: $60,000 × 25 = $1,500,000). Withdrawing 4% in year one and adjusting for inflation annually provides a 95%+ probability of funds lasting 30+ years.
