Understanding Pension Lump Sum vs Annuity
What's the decision? Many pension plans offer a choice: take a one-time lump sum or receive monthly payments for life (annuity).
- Longevity Risk: Live longer than expected? Annuity wins. Die early? Lump sum better for heirs.
- Investment Risk: Annuity is guaranteed. Lump sum depends on market performance.
- Inflation: Fixed annuity loses purchasing power. Lump sum can potentially grow.
- Taxes: Both are taxable as ordinary income when received
- Spouse Protection: Consider survivor benefits in annuity vs inherited lump sum
- Pension Solvency: PBGC insures most pensions up to ~$74k/year
Important: This is a major financial decision. Consult a financial advisor and consider tax implications before choosing.
