Pension vs Lump Sum: Which Should You Choose?
When retiring with a pension, your employer may offer you a choice: take a guaranteed monthly payment for life, or take the lump sum value of your pension and manage it yourself. This is one of the most important financial decisions in retirement.
Choose the monthly pension if: You value guaranteed income, don't want to manage investments, or have health concerns (pension stops at death unless you have a survivor benefit).
Choose the lump sum if: You want control over the money, have a long life expectancy, or can invest the lump sum for higher returns.
This calculator shows your break-even age — the age at which the total pension payments exceed the invested lump sum value. If you expect to live past the break-even age, the monthly pension may be the better choice.
Understanding the Break-Even Analysis
The break-even age is the age at which the total pension payments received equal the future value of the lump sum if invested. Here's how to think about it:
Example Calculation
Suppose your pension pays $2,000/month ($24,000/year) and your lump sum offer is $300,000. If you invest the lump sum at 6% return: (1) At age 65: Pension pays $24,000; Lump sum grows to $318,000. (2) At age 75: Pension pays $240,000 total; Lump sum grows to $537,000. (3) At age 85: Pension pays $480,000 total; Lump sum grows to $965,000. (4) Break-even: Around age 78-80 (depending on exact assumptions).
Factors That Affect Break-Even
- Investment return: Higher returns favor the lump sum; lower returns favor the pension.
- Inflation: Most pensions are NOT inflation-adjusted. Over 20 years, 3% inflation cuts purchasing power by half. The lump sum (invested in stocks/bonds) may keep up with inflation better.
- Life expectancy: If you (and your spouse) live a long time, the pension pays more total dollars. If you die early, the lump sum leaves money for heirs.
- Tax rate: Pension payments are fully taxable. Lump sum in a Traditional IRA is also taxable when withdrawn, but you control the timing and amount.

Risks to Consider
1. Employer Solvency (Pension Risk)
If your employer goes bankrupt, your pension is insured by the PBGC (Pension Benefit Guaranty Corporation). However, PBGC has limits — for 2026, the maximum guaranteed benefit for workers retiring at 65 is ~$7,500/month. If your pension is higher, you could lose the excess. With a lump sum rolled into an IRA, your money is not dependent on your employer's solvency.
2. Inflation Risk (Pension Risk)
Most corporate pensions are NOT inflation-adjusted. A $2,000/month pension today will have the purchasing power of ~$1,200 in 20 years (at 2.5% inflation). Some public sector (government) pensions have COLA (cost-of-living adjustment), but private sector pensions typically don't. The lump sum, if invested in a diversified portfolio, has better potential to keep up with inflation.
3. Investment Risk (Lump Sum Risk)
With a lump sum, you bear the investment risk. If the market crashes, your balance could shrink. However, you can choose a conservative allocation (bonds, CDs) to reduce risk. The pension has no investment risk — the employer bears it.
4. Longevity Risk (Lump Sum Risk)
With a lump sum, you could outlive your money (if you withdraw too much or earn too little). The pension eliminates this risk — you (and your spouse) receive payments for life. To mitigate longevity risk with a lump sum, consider buying an annuity (though annuities have their own risks and costs).
Making the Decision
There's no one-size-fits-all answer. Consider: (1) Your health & family history: If you have a short life expectancy, lump sum may be better. (2) Your risk tolerance: If you're risk-averse, pension may be better. If you're comfortable investing, lump sum may be better. (3) Your spouse's needs: If you want to provide for your spouse after your death, consider a joint-and-survivor annuity (pension) or leave the lump sum in your estate. (4) Get professional advice: This is a complex decision. Consider hiring a fee-only financial planner to run the numbers for your specific situation.
