How much do I need to retire?

Multiply your expected annual retirement expenses by 25. This is based on the 4% safe withdrawal rate. For example, $60,000/year in expenses requires a $1,500,000 portfolio. Subtract guaranteed income like Social Security before calculating — if you expect $24,000/year from Social Security, you only need to fund $36,000/year from savings, requiring a $900,000 portfolio.

What is the 4% rule for retirement?

The 4% rule states you can withdraw 4% of your portfolio in year one of retirement, adjust for inflation each year, and your money should last 30+ years in most historical market scenarios. It originated from the 1998 Trinity Study. For retirements longer than 30 years, a 3.5% withdrawal rate is considered safer.

When should I claim Social Security?

Claiming at 70 vs 62 increases your monthly benefit by approximately 77%. The break-even point — where delaying pays off — is typically around age 78-80. If you expect to live past 80 and have other income to bridge the gap, delaying to 70 is usually the better financial choice. For married couples, the higher earner should generally delay to maximize the survivor benefit.

How much should I have saved for retirement by age?

According to Federal Reserve data, US median retirement savings by age are approximately: age 35: $45,000; age 40: $93,000; age 45: $145,000; age 50: $203,000; age 55: $290,000; age 60: $368,000. A common benchmark is to have 1x your salary saved by 30, 3x by 40, 6x by 50, and 10x by retirement.

What is a Monte Carlo simulation for retirement?

A Monte Carlo simulation runs your retirement plan through thousands of randomly generated market scenarios to show the probability your savings will last. Instead of assuming average returns every year, it models the full range of possible outcomes including bad sequences of returns. A success rate above 90% is considered very safe; above 80% is generally acceptable.

What are the 401k contribution limits for 2026?

For 2026, the 401k employee contribution limit is $24,500 (under age 50) or $32,500 (age 50+). Workers aged 60-63 can contribute up to $35,750 under the super catch-up provision. The IRA contribution limit is $7,500 ($8,600 if 50+). The HSA limit is $4,400 for individuals and $8,750 for families.

How does inflation affect retirement savings?

At 3% annual inflation, your purchasing power is cut in half every 24 years. For a 30-year retirement, $60,000 in expenses today would cost over $145,000 in year 30. To protect against inflation: stay invested in stocks throughout retirement, delay Social Security to maximize COLA-adjusted benefits, consider TIPS bonds, and use a realistic 2.5-3% inflation assumption in your retirement calculator.

Yes, retiring at 55 is achievable but requires more savings than a traditional retirement. With a 40-year retirement horizon, use a 3.5% withdrawal rate (28-30x annual expenses instead of 25x). Key challenges: no Medicare until 65 (budget $800-1,500/month for health insurance), no Social Security until 62 at earliest, and no penalty-free 401k access until 59.5 (except via the Rule of 55 for your current employer's plan).

Pension Lump Sum vs Monthly Annuity: How to Decide

A shrinking but still significant share of workers face a consequential retirement decision: take the pension as a single lump sum, or receive a guaranteed monthly check for life? There's no universal right answer — but there is a right process for deciding.

What Each Option Actually Is

Lump sum: your employer pays out the present value of your pension in cash, which you roll into an IRA and invest. You control it, you can leave it to heirs, but you bear all the market and longevity risk.
Annuity (monthly benefit): you receive a fixed (sometimes inflation-adjusted) payment for life. It's essentially longevity insurance — you can't outlive it — but it typically ends or shrinks at death, and it's exposed to the employer's or insurer's solvency.

Step 1: Calculate the Implied Payout Rate

The first sanity check is the payout rate: annual annuity payment ÷ lump sum. For example, a $400,000 lump sum that pays $24,000 a year implies a 6% payout rate.

Now compare that to what a comparable single-premium immediate annuity (SPIA) would cost in the open market for someone your age. If the pension's implied rate is much higher than a commercial annuity's, the monthly benefit is generous. If it's lower, the lump sum may be the better deal.

Step 2: Check the breakeven age

Divide the lump sum by the annual payment to get the breakeven in years — the point at which cumulative payments equal the lump sum. A $400,000 lump sum paying $24,000 a year breaks even at about 16.7 years. If you'd need to live past that age (plus the return you could have earned investing the lump) for the annuity to win, weigh your health and family longevity honestly.

The Factors That Tip the Decision

Health and longevity. The annuity wins big if you live a long time. If you have a shortened life expectancy, the lump sum (which passes to heirs) is usually better.
Other guaranteed income. If Social Security already covers your essential expenses, you may not need another lifetime guarantee — the lump sum's flexibility and legacy value can matter more.
Inflation protection. A level pension loses purchasing power every year. A cost-of-living-adjusted pension is worth far more than its headline number. Always compare like with like.
Employer/insurer credit risk. Some pensions are federally backstopped by the PBGC, but often only up to a cap. A financially stressed plan adds risk to the annuity option.
Legacy goals. A lump sum can be inherited; a single-life pension usually can't. If leaving money to family matters, that's a point for the lump sum.
Survivor benefits. A joint-and-survivor annuity keeps paying your spouse after you die, at a lower monthly amount. Value that protection explicitly.

Why the "Free Lunch" Is Real for Some

Annuities carry a mortality credit: the pool of annuitants shares the risk that any one of them dies early, which lets insurers pay more than a bond portfolio could sustain on its own. For a healthy person who wants maximum guaranteed income and has no strong legacy motive, that credit can make the pension annuity genuinely the higher-value choice.

Run Both Scenarios Before You Decide

The right way to decide is to model your retirement both ways and compare outcomes across a range of lifespans and market returns. A lump sum invested aggressively might fund a bigger lifestyle — until a bad sequence of returns hits early. A pension might guarantee income — but leave a smaller estate.

Use our retirement planner to enter the pension as either an income source or a lump-sum asset, and compare the projections side by side. You can also read our guide to withdrawal strategies for how guaranteed income changes the rest of the plan.

The Bottom Line

Compare the implied payout rate to open-market annuities, calculate your breakeven age, weigh health and legacy goals, and stress-test both paths. There's no formula that decides it for you — but a disciplined comparison will make the choice obvious for your situation.
