Part-time federal employment under FERS counts towards retirement eligibility, meaning it does not delay when an employee can retire. However, actual FERS pension payments will be reduced by a proration factor based on the ratio of hours worked part-time versus full-time. While the high-3 salary used for pension calculation considers full-time equivalent pay, the proration factor is applied afterward to reduce the final pension amount. The FERS supplement and survivor benefits are also subject to this reduction, but retirement health insurance benefits are unaffected.
