How Pension Options Work
| Option | Description | Pros | Cons |
|---|---|---|---|
| Lump Sum | One-time payment you invest on your own | Control, potential growth, inheritance | Investment risk, longevity risk |
| Annuity | Monthly payments for life | Guaranteed income, no investment risk | No control, no inheritance, inflation risk |
The Break-Even Concept
The break-even age is when the total value of the lump sum (if invested) equals the total annuity payments received. After the break-even age, the annuity option becomes more valuable.
Example:
| Variable | Value |
|---|---|
| Lump Sum Offer | $250,000 |
| Monthly Annuity | $1,200 |
| Investment Return | 6% |
| Current Age | 65 |
| Life Expectancy | 85 |
| Break-Even Age | ~79 years |
- If you live to age 79, both options are equal.
- If you live past age 79, annuity is better.
- If you die before age 79, lump sum is better.
