Americans who postpone retirement saving face a compounding penalty that can triple monthly contributions needed, even as 2026 IRS limits raise 401(k) caps to $24,500 and IRA caps to $7,500.

Retirement delay costs 3x more as 2026 limits rise to $24,500
Postponing retirement saving until your 30s can triple the monthly contribution needed to catch up, yet median savings for Americans aged 55 to 64 stand at just $185,000 against a perceived $1.46 million retirement target.
"For every 10 years you delay before starting to save for retirement, you may need to save three times as much each month to catch up because you lose years of compound growth," David Poole, head of Citigold North America, said.
The gap between what Americans have saved and what they believe they need is widening. Median retirement savings for those aged 55 to 64 is $185,000, while those 65 to 74 hold $200,000, according to the Federal Reserve's most recent Survey of Consumer Finances. Yet Americans believe they need about $1.46 million to retire comfortably — up more than 15 percent from the prior year — per Northwestern Mutual's 2026 Planning & Progress Study. Nearly half, 48 percent, say it's somewhat or very likely they'll outlive their savings.
The IRS raised 2026 contribution limits across multiple retirement account types in November, giving savers more room to close that gap. The 401(k) cap rose to $24,500 from $23,500, while the IRA limit increased to $7,500 from $7,000, according to the IRS announcement on November 13, 2025.
The Compounding Cost of Delay
The math behind Poole's warning is straightforward. A 25-year-old who saves $500 monthly at a 7 percent annual return would accumulate roughly $1.2 million by age 65. Starting at 35 with the same monthly contribution yields only about $570,000 — less than half. To reach the same endpoint, the later starter would need to save roughly $1,100 monthly, more than double the original amount.
The average American starts saving for retirement at age 31 and aims to retire at 65, according to the Northwestern Mutual study. That means most workers have already lost several years of compounding before their first contribution. The study also found that 46 percent of Americans don't expect to be financially prepared at retirement, yet 36 percent haven't taken any steps to address the shortfall.
Retirement account balances hit a record average of $167,970 in 2025, according to Fidelity data, showing that those who do save are benefiting from market gains. But the median figures from the Fed's survey tell a different story — half of American households have far less than the average suggests.
2026 Limits Offer a Catch-Up Path
For workers 50 and older, the new limits provide a concrete mechanism to accelerate savings. The catch-up contribution limit for 401(k) plans rose to $8,000 in 2026 from $7,500, enabling workers 50 and older to contribute up to $32,500 total. The SECURE 2.0 Act's enhanced catch-up provision allows those aged 60 to 63 to contribute an additional $11,250, bringing their total to $35,750.
IRA catch-up contributions increased to $1,100 for those 50 and older, raising the total IRA limit to $8,600. SIMPLE plan catch-up limits also rose, with workers 50 and older able to contribute up to $4,000 extra and those 60 to 63 up to $5,250.
Financial advisors recommend several benchmarks to gauge progress. Fidelity suggests saving three times your pre-retirement salary by age 40, six times by 50, eight times by 60 and 10 times by 67. The "25x rule" targets 25 times expected annual retirement spending, while the "80 percent rule" aims for retirement income at 80 percent of pre-retirement earnings.
Poole says it's never too late to start, though the strategy may need adjustment. "That could mean saving more aggressively, delaying retirement or thinking carefully about when to claim Social Security," he said. Four in 10 Americans plan to work during retirement, according to the Northwestern Mutual study, with more than half saying they want to stay active rather than purely for income.
