Should I take the lump sum or the annuity?

Most financial planners suggest taking the annuity if you want guaranteed lifetime income and your spouse would receive meaningful survivor benefits. Take the lump sum if you can earn more than the annuity's implicit rate through investing, want flexibility for legacy planning, or have a shorter life expectancy (health factors, family history). A common rule of thumb: if the annuity offers a 5%+ payout rate relative to the lump sum (a $30,000/year annuity on a $500,000 lump = 6% payout rate), it is usually a strong offer.

What is the break-even point for a pension?

The break-even point is the age at which the cumulative annuity payments equal the lump-sum amount. Calculation: break-even years = lump sum ÷ annual annuity. Example: $500,000 lump sum and $30,000/year annuity → break-even at 16.7 years. If you die before break-even, the annuity loses; after break-even, the annuity wins. Most retirees with average life expectancy (78-85) and typical annuity terms reach break-even before death, making the annuity the better choice for many.

What is a survivor benefit in a pension?

A survivor benefit continues payments to your spouse (or another beneficiary) after your death. The most common form is the "50% joint and survivor" option, where your spouse receives 50% of your monthly benefit for the rest of their life. Choosing this option reduces your monthly benefit during your lifetime — typically by 5-15% — but provides income to a surviving spouse. The 100% joint-and-survivor option leaves your full benefit to a spouse but cuts your payments more, usually 10-20%. Our pension calculator estimates a 50% survivor benefit by default.

Is my private pension protected if the company fails?

Private-sector defined-benefit pensions are typically insured by the PBGC (Pension Benefit Guaranty Corporation) up to certain limits. As of 2026, the maximum annual guarantee for a 65-year-old retiree is roughly $7,000-$7,500 per month for a single-life annuity, with lower caps for earlier retirees. State and local government pensions are usually NOT covered by PBGC but are backed by the issuing jurisdiction. Lump-sum offers from a troubled employer sometimes reflect funding pressure rather than fair value — consult a financial advisor before accepting.

How are pensions taxed?

Pension annuity income is taxed as ordinary income at your marginal federal and state tax rates. If you roll the lump sum into an IRA, future withdrawals are taxed as ordinary income. If you take the lump sum and it includes employer stock, you may qualify for Net Unrealized Appreciation (NUA) treatment — the employer stock portion is taxed at long-term capital gains rates when distributed, rather than ordinary income rates. This can save significant tax if the stock has appreciated substantially. Our pension calculator shows gross payouts; actual tax depends on your total income and filing status.

What is a defined-benefit pension?

A defined-benefit pension pays you a guaranteed monthly income for life after you retire, based on a formula using your salary and years of service. Many plans also offer a one-time choice at retirement: take the lifetime monthly payments, or take a lump sum that you can roll into an IRA. The right choice depends on the lump-sum-to-annuity payout rate, your life expectancy, your other income sources, and the importance of spousal survivor benefits. The calculator below projects the present value of each option and the break-even age at which the annuity overtakes the lump sum.

Estimates only. Pension guarantees are typically insured by the PBGC up to certain limits for private-sector defined-benefit plans. Tax treatment differs: annuity income is fully taxable, while lump sums may qualify for net unrealized appreciation (NUA) treatment or roll into an IRA.

Which option fits you?

Choose the annuity if...

You want predictable lifetime income
You have a spouse who would benefit from survivor coverage
You worry about outliving your savings
You do not want to manage investments

Choose the lump sum if...

You can earn more than the implicit annuity rate
You want flexibility for legacy or RMD planning
You have a short life expectancy (health factors)
You want to use NUA tax treatment on employer stock

Most financial planners recommend the annuity when the "mortality credit" — the return earned on pooled survivor benefits — exceeds what you can safely earn on your own. For a healthy 65-year-old, this often favors the annuity; for someone in poor health or with above-average investment skill, the lump sum usually wins.

A pension calculator is a free tool that compares a defined-benefit pension offer against two choices: take a monthly annuity stream for life, or take a lump-sum payout. It computes the present value of the annuity stream (using your assumed discount rate), the break-even age, lifetime annuity totals, and the spousal survivor benefit. The pension calculator helps you decide which option better fits your financial situation and life expectancy.

How it works

How to compare a pension lump sum to a monthly annuity

Our pension calculator compares a lump-sum pension offer against a monthly annuity stream, showing the present value, break-even point, lifetime totals, and survivor benefits.

1
Enter the monthly pension offer
Type the gross monthly amount the plan sponsor is quoting for the single-life annuity option. This is the base benefit before any survivor reduction.
2
Enter the guaranteed payout years
Type the number of years the annuity is guaranteed to pay (often 'for life', modeled as 25-30 years; or a specific period certain like 10 or 20 years).
3
Enter the lump sum and discount rate
Type the lump-sum cash offer and your assumed investment return if you took the lump. The pension calculator discounts the annuity stream at that rate to find its present value, then compares to the lump sum.
4
Set life expectancy and retirement age
Type your retirement age and life expectancy in years. The pension calculator uses these to show lifetime totals and the break-even point where cumulative annuity payments exceed the lump sum.
5
Read the side-by-side comparison
The pension calculator shows the present value of the annuity, the lump sum, the break-even year, the lifetime annuity total, and the spousal survivor benefit. It also gives a guidance summary of which option generally fits which kind of retiree.
