A pre-tax election may reduce Social Security-covered earnings. These examples compare a potential retirement benefit change with setting aside your estimated monthly paycheck increase.
Social Security assumptions. Educational comparison, not a personal benefit estimate. Assumes 35 years at the employee’s current monthly wage base (income minus other pre-tax deductions, following the paycheck model), with the selected 10, 20, or 30 years included in those highest 35 years. Uses the 2026 covered-wage limit of $184,500 and the 2026 benefit formula: 90% of the first $1,286 of average indexed monthly earnings, 32% from $1,286 to $7,749, and 15% above $7,749. Compares benefits at full retirement age, before SSA rounding. Spouse income is excluded.
The model freezes wages and SSA parameters in 2026 dollars and does not perform historical wage indexing or forecast inflation, future wage limits, bend points, or cost-of-living adjustments. Actual effects depend on your earnings record, whether affected years enter your highest 35 years, retirement age, and program rules. Other pre-tax deductions may not all reduce Social Security wages; confirm covered wages with payroll. This illustration does not assess eligibility credits, disability benefits, or survivor benefits.
Savings assumptions. Constant deposits at month-end for the same 10-, 20-, or 30-year period, with a hypothetical 8% nominal annual return compounded monthly, before taxes and fees. Retirement assumes 4% nominal annual growth compounded monthly and equal month-end payouts for 25 years (300 payments). Each payout uses both investment growth and principal, drawing the balance down to zero after the final payment; this is not a 4% withdrawal rule and does not reserve an ending balance for heirs.
Social Security retirement benefits generally continue for life and may receive cost-of-living adjustments, while this modeled investment payout ends after 25 years and does not increase with inflation. Social Security may also provide eligible survivor benefits, which are not modeled here. Investment balances and payouts are future nominal dollars; Social Security changes use frozen 2026 parameters, so the comparison is not inflation-adjusted. Returns are hypothetical, can be negative, and are not guaranteed; variable returns, taxes, and fees could exhaust funds sooner. These examples do not guarantee replacement of Social Security benefits and are not investment or tax advice.
