How This Calculator Works

This tool models the after-tax value of two strategies, assuming you invest all net Social Security income.

  • Scenario 1: Claim at 62 & Invest (Blue Line)
    • - Starts with a reduced benefit (70% of PIA).
    • - **(Tax Impact 1)** While working, your salary and filing status are used to calculate "provisional income." This determines how much of your benefit is taxed (at your Marginal Tax Rate) *before* you can invest it.
    • - **(Tax Impact 2)** The Earnings Test (2025 limit: $23,400) further reduces your benefit.
    • - **(Tax Impact 3)** Your investment growth is taxed at the Capital Gains Rate annually.
    • - After stopping work, your "Other Retirement Income" is used to see if benefits are *still* taxable.
  • Scenario 2: Wait until 70 & Invest (Red Line)
    • - You receive $0 in benefits from age 62 to 69. Your investment pot is $0.
    • - At age 70, you start receiving a permanently larger, tax-free gain (124% of your PIA) thanks to Delayed Retirement Credits.
    • - This larger benefit is then taxed based on your "Other Retirement Income" to find the net amount to invest.
    • - This investment's growth is also taxed at the Capital Gains Rate annually.
