What working another year is actually worth
A paycheck is not just salary minus tax. Near retirement, work can change healthcare, Social Security, Medicare premiums two years later, retirement savings, and how much you draw from the portfolio.
What RetireRebel separates
Gross pay comes first. Then the model separates payroll tax, federal tax, state tax, health premium or ACA subsidy changes, Social Security earnings-test withholding, work-related costs, and other current-year reductions.
Retirement contributions and employer match are not treated as money lost. They may reduce cash you can spend this year, but they remain household wealth. Employer health coverage is also handled carefully: if it replaces marketplace coverage, the model uses the actual modeled premium change instead of inventing a separate benefit.
What can show up later
Extra income can affect IRMAA two years later, Social Security withholding before full retirement age, ACA premiums before Medicare, taxes, withdrawals avoided, investment growth, and survivor results. That is why RetireRebel shows spendable cash separately from saved or benefit value.
Part-time or flexible income can reduce portfolio withdrawals, leave more money invested to grow, create a health-insurance bridge before Medicare, or make it easier to delay Social Security. That does not mean paid work belongs in your retirement; it is just one optional lever to model.
A plan that says work until 70 also needs a backup if layoffs, health, caregiving, or job availability intervene. Retirement can still include flexible income, but the plan should not depend on work being required.
Run this with your numbers or ask the Rebel what working one more year changes.
