A Silicon Valley Survey Shows Housing Is a Major Burden, While Social Security Pays the Same No Matter Where You Retire

A Silicon Valley survey found that almost all residents view housing costs as a major problem, but one retirement income source stays the same regardless of where you live. That detail could influence where you decide to spend your retirement years.

Housing and everyday expenses are putting pressure on people in Silicon Valley. A Joint Venture Silicon Valley poll found that 95% of residents regard housing and affordability as serious problems, according to a release. For anyone nearing retirement, that raises an important question about the one income stream that does not change based on location.

Consider a hypothetical longtime tech worker named Mark. After three decades with San Jose employers, he expects to receive a Social Security benefit of $3,000 a month. He is weighing whether to remain near his children in San Jose or relocate to Tupelo, Mississippi, where a college friend retired. In either place, the benefit equals $36,000 a year before taxes and deductions.

Your Benefit Formula Never Asks for Your Address

Social Security retirement benefits are determined by two things: your lifetime earnings subject to payroll tax and the age at which you claim. Your ZIP code is not part of the calculation. Mark would receive the exact same payment whether he lived in a San Jose condo or a Tupelo ranch house.

Annual increases work the same way. Social Security has announced a 3.6% cost-of-living adjustment for 2027. It is a single national adjustment tied to an inflation measure based on what workers in cities around the country spend. On a $3,000 check, that amounts to about $108 more each month in both places, even though local prices have not moved at the same pace.

How Far $36,000 Goes in Each State

Federal price data highlights the difference. The 2024 regional price index places California at about 111 and Mississippi at about 87, with 100 representing the national average. California is the most expensive state in the dataset, while Mississippi ranks second lowest, behind Arkansas.

Adjusted for those price levels, Mark’s $36,000 benefit has the purchasing power of about $32,500 in California versus about $41,400 in Mississippi. That is roughly $8,900 more in annual buying power based on statewide averages, even though his Social Security payment does not change.

These figures are statewide averages that combine costly metro areas with cheaper rural regions, so the difference between two individual cities could be larger or smaller. Housing accounts for much of the gap, including rent or mortgage payments, property taxes, and homeowners insurance. Moving changes the bills Mark faces, while the check itself stays the same.

What Moves With You and What Changes at the State Line

Some federal costs follow you wherever you go. The standard Medicare Part B premium is $202.90 a month and is usually deducted from the benefit. That leaves Mark with about $2,797 in either city.

Federal taxation of benefits also follows national rules. For a single filer, the IRS adds other income to half of Social Security benefits. Once that total exceeds $25,000, part of the benefit becomes taxable, and above $34,000, as much as 85% may be taxed. Since half of Mark’s benefit is already $18,000, even modest 401(k) withdrawals could push him over those thresholds in either location.

State rules are where location starts to matter. California and Mississippi both exempt Social Security benefits from state income tax, so this move would not change that part of the picture. Supplemental Security Income, the separate program for retirees with very low income, is different: California provides a state supplement, while Mississippi does not.

Two Choices That Determine What Your Check Can Do

The first step is to compare the expenses. Because the benefit amount is fixed either way, the real comparison is housing, property taxes, insurance, and proximity to family and doctors. It is better to estimate what you would actually spend in each place than to rely on average prices.

The second step is to separate the two decisions. The age you claim Social Security determines the size of the check, and delaying increases it for the rest of your life. Where you live determines what that check can buy. Claiming is harder to reverse: you can move again later, but filing early permanently locks in a smaller benefit.

Mark’s monthly deposit will be $3,000 in either city. In Tupelo, that amount might cover housing costs and leave room for trips back to see his children in San Jose. In California, the same check could struggle to cover rent. Before moving, Mark would need to balance those savings against the cost of living farther from family.
