Step-by-Step Examples
Example 1
Standard Pension
$2,500/mo, 20 years, 4% discount, $350k lump sum offered.
- Total nominal: $600,000
- PV at 4%: ~$413,000
- Lump sum $350k < $413k PV
- Monthly payments win in this case
✓ PV $413k > lump sum $350k — take monthly
Example 2
High Discount Rate
$2,500/mo, 20 years, 7% discount, $350k lump sum.
- PV at 7%: ~$319,000
- Lump sum $350k > PV $319k
- At aggressive return assumption, lump sum wins
✓ Lump sum wins at 7% alternative return
Example 3
Short Collection
$3,000/mo, 10 years only (health concern), 4% discount.
- PV: ~$295,000
- Shorter horizon favors lump sum if offered near this figure
✓ PV ~$295k — lump sum may be preferable

Common Mistakes to Avoid
⚠️
Ignoring survivor benefit reduction
Joint-and-survivor pension reduces monthly payment but continues after your death. Include that value.
⚠️
Too-high discount rate justifying lump sum
Aggressive return assumptions can make any lump sum look attractive. Use realistic retirement-appropriate return.
⚠️
Forgetting pension insurance
Private pensions backed by PBGC (up to ~$7,107/mo in 2024) are safer than many assume.
