The 90/10 rule—investing 90% in a low-cost S&P 500 index fund and 10% in short-term government bonds—is generally considered excellent for long-term growth and younger investors but too aggressive for many retirees. It maximizes returns and battles inflation, but high volatility makes it risky for those needing immediate, steady income.
In his article for the Journal of Retirement, titled "Global Asset Allocation in Retirement: Buffett's Advice and a Simple Twist," Estrada argues that a 90/10 (stock/bond) allocation has a low failure rate, good downside protection, and high upside potential — a winning combination.
Buffett argues that stocks will continue to provide higher returns over the long run than bonds or cash. Invest the remaining 10% in short-term government bonds such as U.S. Treasury bills. This ensures liquidity (your ability to buy or sell with relative ease) while reducing your overall risk in market downturns.
Buffett recommended something strikingly simple: put 90% of the money in a low-cost S&P 500 index fund and the remaining 10% in short-term government bonds. This is a rather straightforward approach, and it has been dubbed the 90/10 rule.
Only a small fraction of retirees, around 3.2%, have $1 million or more in retirement savings, according to recent Federal Reserve data, making it a rare achievement despite many people believing it's necessary for comfort. The majority have significantly less; the median savings for households aged 65-74 is much lower, around $200,000, highlighting a large gap between the goal and reality, though high-income households fare better.
The top ten financial mistakes most people make after retirement are:
With $900,000 saved, and factoring in an average annual rate of return between 10–12%, you'll have between $90,000 and $108,000 to live off of each year, not including your Social Security benefits.
Between 1926 and 2022, a 90/10 portfolio produced average returns of 9.9%. By comparison, an evenly split 50/50 portfolio produced returns of 8.1%, a significantly lower amount.
Buffett's 90/10 rule works best for long-term investors with a horizon of at least 10 years. It suits those comfortable with stock market swings and confident in U.S. economic growth. However, the strategy may be too aggressive for retirees or conservative investors.
Investing solely in the S&P 500 may work for young investors, but it won't provide diversification for retirement security. Overlapping holdings in different funds can result in redundancy rather than true diversification. Diversification involves seeking uncorrelated sources of return using different asset classes.
The "27.39 rule" (often rounded to $27.40) is a simple financial strategy to save $10,000 in one year by consistently setting aside $27.40 every single day, making it an achievable micro-saving habit to build wealth or an emergency fund. It turns the daunting goal of saving $10,000 into a manageable daily action, emphasizing consistency over large lump sums.
A good retirement income is often cited as 70% to 80% of your pre-retirement income, but many experts now suggest aiming for closer to 100%, especially in early retirement, to cover varying lifestyles, travel, and healthcare costs, with a solid starting point being around $5,000-$8,000/month depending on your current earnings and desired lifestyle. This number isn't universal; adjust upward for luxury travel or high-cost areas, and downward if downsizing or paying off debts.
Only a small percentage of Americans retire with $1 million or more in retirement savings, with figures from the Federal Reserve and Employee Benefit Research Institute (EBRI) showing around 3.2% of retirees hitting that mark, though some sources cite slightly lower numbers for all Americans (around 2.5%) or higher estimates for households nearing retirement (over 10% of older households have $1M+ net worth, not just retirement funds). The reality is most retirees have significantly less, with the median for ages 65-74 being around $200,000-$609,000 in retirement accounts.
Retirement Regret #1.
Retiring as soon as possible can be a priority, but retiring too early can be a big mistake. For one, premature retirement can mean gambling with your financial security in the future. If you leave work too early, you could be forfeiting some key, higher-earning years to build up your savings.
Suze Orman's key retirement advice emphasizes starting early (15% savings from age 25), prioritizing Roth accounts for tax-free withdrawals, maximizing employer matches, waiting until age 70 for Social Security, building a large emergency fund (2-3 years' expenses after 50), and considering home equity (reverse mortgages) for income if needed, all while living below your means to save more today for less spending tomorrow.
