Keep pension and savings separate.

Pension is a recurring payment. TSP is an account balance with investment uncertainty. The lump-sum scenario excludes exact retirement dates, taxes, installments and disability offsets. A future retirement would use the discount rate in effect at that time. Official comparison results are published in the methodology.
