Social Security Estimator

Use this educational tool to compare retirement assumptions. The interactive calculator loads with JavaScript; the explanation below is available to every visitor. Quantos LLC publishes MyFedPlan independently of the U.S. government. Estimates are not official benefit determinations.

Read the methodology and model limits and our federal retirement guides.

Interpreting Social Security estimates responsibly

Social Security estimates should be treated as planning inputs, not fixed guarantees. Claiming age, work history updates, and policy changes can affect outcomes. Use this estimator alongside your pension and TSP projections so total retirement cash flow is evaluated as a system rather than as disconnected numbers.

  • Compare claiming ages to understand the monthly benefit tradeoff.
  • Revisit estimates after substantial earnings changes.
  • Use conservative assumptions when building long-term retirement budgets.

Frequently asked questions

Can Social Security alone close my retirement gap?

For most federal retirees, it should be analyzed as one component of a broader multi-income plan.

How often should this estimate be refreshed?

At least annually and any time you materially change retirement timing assumptions.
