My Savings Tripled Over 25 Years—Is That Good Enough for Retirement?

Core Insights - Tripling savings over 25 years results in a 4.5% annual return, which is only slightly above inflation and significantly lower than the average returns of a simple index fund [1][3][7] - The adequacy of savings for retirement is determined more by the total amount saved and its ability to cover expenses rather than the growth rate [2][7] Investment Performance - A 4.5% annual return is reasonable for low-risk investments like high-yield savings accounts or Treasury bonds, but it is substantially lower than the S&P 500's average return of 8.15% from 2000 to 2025 [3][4] - Inflation reduces the real return to approximately 2%, which is insufficient for wealth accumulation unless starting with a large sum or maintaining low spending [5] Retirement Readiness - Retirement readiness is assessed by whether savings can replace 70% to 80% of pre-retirement income throughout life expectancy [6][8] - Key benchmarks include saving eight to ten times annual salary or enough to cover 25 times estimated annual retirement expenses [9][10] Personal Financial Situations - Tripling savings may suffice if fixed expenses are low, such as having no mortgage or debt, and if there are additional income sources like Social Security or pensions [9]
