401(k) by Age: How Much Should You Have Saved in 2026?

"How much should I have in my 401(k) by age?" is one of the most searched retirement questions in the United States — and one of the most anxiously typed into a search bar at 11pm. The honest answer is that any benchmark is a simplification of a complex personal calculation, but having benchmarks is still valuable because they force the question: am I on track?

This guide provides the most widely used 401(k) savings benchmarks, explains the assumptions behind them, shows what to do if you are behind, and helps you calculate your own personalised target using the 2026 IRS limits.

The Fidelity Rule of Thumb: 401(k) Savings by Age

Fidelity, which administers more 401(k) plans than any other provider in the United States, publishes widely-followed savings benchmarks based on a multiple of your annual salary.

These assume you start saving at 25, save 15% of gross income (including employer match), retire at 67, and plan to live on 45% of pre-retirement income from savings (with Social Security covering the rest).

How Do Most Americans Compare?

The Federal Reserve's 2022 Survey of Consumer Finances and Vanguard's 2023 "How America Saves" report provide a clearer picture than averages, which are skewed by very high-balance accounts.

The gap between median and mean is enormous — a small number of very wealthy savers pulls the average up. The median is the more realistic comparison point for most workers.

The Real Benchmark: Your Personal Retirement Number

Salary multiples are a useful starting point but they do not account for your lifestyle, planned retirement age, expected Social Security benefit, or actual expenses. A more precise approach:

Step 1: Estimate your desired annual retirement income. Most planners target 70–80% of pre-retirement income. If you earn $100,000, target $70,000–$80,000/year in retirement income.

Step 2: Subtract expected Social Security income. The average Social Security benefit for a retired worker in 2025 is approximately $1,907/month ($22,884/year). Check your personalised estimate at ssa.gov/myaccount.

Step 3: Calculate how much your portfolio needs to provide. If you want $75,000/year and Social Security covers $23,000, your portfolio must cover $52,000/year.

Step 4: Apply the 4% rule. Multiply your annual portfolio draw by 25. $52,000 × 25 = $1,300,000 required portfolio.

Step 5: Use the 401(k) calculator to see if your current balance and contributions are on track to reach $1,300,000 by your target retirement age.

2026 401(k) Contribution Limits

The IRS increased employee contribution limits for 2026:

If you are behind on savings, the catch-up contribution provisions — especially the SECURE 2.0 super catch-up for ages 60-63 — are among the most valuable tools available.

What to Do If You Are Behind

At age 30: Start immediately and increase by 1% per year.

Being behind at 30 is recoverable because time is still on your side. Compound growth does most of the heavy lifting in years 20-35 of investing. Even starting from zero at 30 and contributing $800/month at 7% return reaches $998,000 by age 65.

At age 40: Maximise contributions and reduce fees.

A 1% annual fee difference on a $150,000 balance at 40 costs approximately $120,000 in foregone wealth by age 65. Switch to low-cost index funds if your plan allows. Target-date funds through Vanguard, Fidelity, or Schwab typically charge 0.10–0.15% annually.

At age 50: Use catch-up contributions and delay Social Security.

The $8,000 catch-up contribution starts at 50. At 7% return, contributing the full $32,500/year from age 50 to 65 adds approximately $850,000 to your balance. Delaying Social Security from 62 to 70 increases your monthly benefit by approximately 76% — one of the highest guaranteed returns available.

At age 60-63: Use the SECURE 2.0 super catch-up.

Workers aged exactly 60, 61, 62, or 63 can contribute $35,750/year to their 401(k) in 2026 — $11,250 more than other 50+ employees. This provision started in 2025 and remains underused. Over 4 years at 7% return, this additional $11,250/year contributes approximately $50,000 extra to your retirement balance.

The Employer Match: Free Money You May Be Leaving Behind

The most expensive 401(k) mistake is failing to capture the full employer match. If your employer matches 50% of contributions up to 6% of your salary and you contribute only 3%, you are declining part of your compensation.

Over 20 years at 7% return, $1,200/year in foregone match equals approximately $49,000 in lost retirement wealth — from a $60,000 salary worker simply not knowing to contribute 6% instead of 3%.

401(k) by Age: The Honest Conversation

Most Americans are behind the Fidelity benchmarks. The 2023 Vanguard data shows the median 55-64 year old has $185,000 saved against a benchmark of 7× salary — implying a $185,000 median against a $700,000+ target for a median wage earner.

The benchmarks are not a source of shame — they are a planning tool. The earlier you know the gap, the more options you have to close it: higher contributions, lower fees, working slightly longer, adjusting spending expectations, or building additional income streams (rental income, part-time work, Social Security optimisation).
