$1,000,000 in retirement savings sounds like a lot today — but in 25 years at 3% inflation, that $1M has the purchasing power of only $478,000. Inflation is the silent destroyer of retirement plans. This calculator shows the real purchasing power of your projected retirement savings and helps you determine if you are saving enough to account for inflation.
The standard advice of having $1M to retire comfortably was calibrated for a specific time. With 3% average inflation: in 30 years, today's $60,000 lifestyle costs $145,000. Your retirement savings must grow faster than inflation — which means keeping the majority in growth assets throughout retirement, not just bonds.
Healthcare inflation runs 5-7% annually — nearly double general CPI inflation. A retiree spending $12,000/year on healthcare at 65 will spend $30,000-$40,000/year by age 80. This specific inflation category must be specifically planned for in retirement budgets beyond general inflation assumptions.
At 3% average inflation, money loses half its purchasing power every 24 years. $2,000,000 in 2026 has the purchasing power of $1,000,000 in 2050. This means retirees need much more than they think — roughly double the nominal amount for a 25-year retirement at 3% inflation.
Historically stocks have outpaced inflation by 7% annually: 10% returns minus 3% inflation. TIPS guarantee inflation protection but lower returns. Real estate and REITs also outpace inflation over long periods. Pure cash and bonds consistently lose to inflation.
A common adjustment: increase your retirement number by 50-75% to account for inflation. If you calculated $1M needed, target $1.5M-$1.75M. Alternatively use an inflation-adjusted return rate: 7% nominal minus 3% inflation = 4% real return in all retirement calculations.
