Building a Sustainable Retirement Nest Egg

Retirement planning is about ensuring your accumulated wealth outlives your retirement years. Balancing savings rates, asset allocation, and withdrawal strategies guarantees financial independence.

The 4% Rule & Spending Targets

The classic Trinity Study suggests that withdrawing 4% of your investment portfolio in your first retirement year, and adjusting that dollar amount for inflation annually, provides a 95%+ probability that your savings will endure for at least 30 years in a balanced stock/bond portfolio.

Target Retirement Corpus (Rule of 25)

Target Nest Egg = Anticipated Annual Retirement Expenses * 25

If you anticipate needing $60,000 per year from your portfolio to cover living expenses, your target retirement fund is $1,500,000 ($60,000 * 25).

  • Delay Social SecurityDelaying Social Security retirement benefits from age 62 to age 70 increases your guaranteed lifetime monthly payout by up to 77%.
  • Diversify Tax BucketsHolding assets in taxable, tax-deferred (Traditional), and tax-free (Roth) accounts provides maximum tax flexibility in retirement.
