This does not replace the official estimate. Verify service, compensation, age or tier rules, option reductions and plan-specific limits.

Tier still controls the inputs

Tier 1 and Tier 2 use different final-average-salary periods, retirement ages and annual increases. Tier 2 also applies a statutory pensionable salary limit.

Older service can differ

Some pre-July 1998 Tier 1 service may use a graduated formula if it was not upgraded. Use the Benefits Report to identify each service category.
