As retirement approaches for millions of Americans, the financial landscape is increasingly shaped by their personal savings — and government programs.

Nearly half of households headed by someone aged 55 or older have no retirement savings in a 401(k) plan or an IRA, according to the U.S. Government Accountability Office (GAO).

Meanwhile, the Social Security trust fund is projected to be depleted by 2033, potentially triggering benefit reductions of more than 20% if no legislative action is taken.

These sobering statistics underscore the importance of strategic planning, particularly around Medicare enrollment, which carries lifelong financial consequences if mishandled.

Understanding the nuances of Medicare Parts A, B, C, and D — and the penalties for late enrollment — is essential for securing a stable retirement.

Jean Chatzky focuses on Medicare enrollment and Social Security

Jean Chatzky, a personal finance author and founder of HerMoney, has consistently emphasized the importance of informed decision-making in retirement.

Her guidance focuses on the intersection of Medicare and Social Security, urging Americans to take proactive steps to avoid costly mistakes.

In her analysis of Medicare options, Chatzky outlines the risks of missing enrollment windows and the variability in coverage across different plan types.

Her insights are especially relevant as retirees face rising health care costs and increasing life expectancies, both of which demand careful financial preparation.

Chatzky explains Social Security planning

Chatzky cautions that claiming Social Security benefits prematurely can lead to significant long-term reductions in income.

“Waiting to claim benefits until at least full retirement age is generally a good rule of thumb because your payments will be larger,” she said.

The Social Security Administration defines full retirement age based on birth year. For individuals born in 1960 or later, full retirement age is 67, while those born earlier may qualify between ages 66 and 67. Claiming benefits before reaching this threshold can result in a permanent reduction in monthly payments.

Chatzky estimates that early filers could see their benefits reduced by up to 30%, a cut that persists throughout retirement. She underscores the importance of understanding how timing affects benefit amounts, noting that even a few years’ difference in claiming age can have a lasting financial impact.

This reduction not only affects monthly income but can also influence broader retirement planning decisions, especially for those relying heavily on Social Security as a primary source of support.

Chatzky clarifies important facts on Medicare enrollment

Medicare enrollment is not automatic for everyone, Chatzky explains, and failing to sign up during the designated periods can result in penalties that last a lifetime.

The Initial Enrollment Period begins three months before an individual turns 65 and ends three months after that birthday month. Missing this window without qualifying for a Special Enrollment Period can lead to monthly premium increases for Medicare Part B and Part D.

The Medicare Part B penalty adds 10% to the monthly premium for each full 12-month period a person was eligible but did not enroll. For example, someone who delays enrollment by two years would pay 20% more each month for Part B coverage, according to medicare.gov.

Medicare Part D, which covers prescription drugs, also carries a penalty. If an individual goes 63 days or more without creditable drug coverage after becoming eligible, they may face a monthly surcharge of 1% of the national base beneficiary premium for each month they were uncovered.

In 2025, the base premium is $36.78, meaning a 14-month delay would result in an additional $5.20 per month, added to the plan’s premium. These penalties are not one-time fees — they persist for as long as the individual maintains Medicare coverage.

Medicare Part B late enrollment penalties increase by 10% for each year of delay.
Medicare Part D penalties add 1% per month of delay to the base premium, which is $36.78 in 2025.
Defined-benefit pension plans now cover only 13.5% of working-age Americans.
