"So teach us to number our days, that we may get a heart of wisdom." - Psalm 90:12 If you're a few years from retirement and your savings aren’t quite where you want them, you might feel like you've run out of time. But maybe you don’t need a time machine to solve the problem. Today, Matt Bell joins us with some encouraging words about beefing up retirement savings.Matt Bell is the Managing Editor at Sound Mind Investing, an underwriter of Faith & Finance. The Surprising Power of Working a Little LongerIn 2018, a Stanford study called The Power of Working Longer made a compelling discovery: delaying retirement by just three to six months can have the same impact on retirement readiness as saving an additional 1% of income every year for 30 years.Yes, really.This is largely due to two factors:Higher Social Security Benefits – For every month you delay past full retirement age, your benefit increases by 2/3 of 1% (8% annually). Better Annuity Rates – The older you are when purchasing an annuity, the more monthly income you’ll receive for the same investment.But there’s a caveat: the study is based on specific assumptions that may not match your financial situation.What the Study Assumes—and Why It MattersThe Stanford study uses a fictional worker named “John” who:Started saving at age 36Saved 6% of income and received a 3% matchRetired at 66 and claimed Social Security immediatelyUsed all savings to buy an inflation-indexed annuityIn reality, your income, savings rate, Social Security timing, and withdrawal strategy may differ widely. Not to mention, indexed annuities like the one in the study are no longer widely available. So while the study provides encouragement, its specifics shouldn’t be universally applied.If you can delay claiming Social Security, it can significantly boost your lifelong income. For example, waiting until age 70 instead of 66 could result in a monthly check that’s 24% higher. You’d need to live roughly 12 more years to “break even,” but many retirees today are living well into their 80s and beyond.Social Security is essentially a government-backed, inflation-adjusted annuity, making it a powerful foundation for retirement income.More Benefits to Working LongerBeyond Social Security, staying employed offers additional financial and emotional perks:More Contributions – Additional working years allo
