Step 3 – Calculate benefits & tax impact
Scenario 1 – future years at current salary
–
Estimated monthly SS benefit at claiming age.
Scenario 2 – future years at plug-in salary
–
Estimated monthly SS benefit at the same claiming age.
| Remaining working years (to claiming age) | – |
| Years receiving benefits (claim age → life expectancy) | – |
| Extra monthly SS benefit (Scenario 2 − Scenario 1) | – |
| Extra lifetime SS benefit (monthly × years of benefits) | – |
| Extra tax per year (Scenario 2 − Scenario 1) | – |
| Extra tax total (until claiming age) | – |
| Net: extra SS − extra tax (nominal) | – |
