Retirement savings advice is often either too vague ("save as much as you can") or too intimidating ("you need $2 million"). Neither helps you make a decision today. What you need are calibrated benchmarks and a rule of thumb that adjusts to your real situation — and a way to know if you're roughly on track without a spreadsheet degree.
What changed in 2026
- Longevity risk increased. Improved healthcare means retirement can last 25–35 years for many people. Planning for a 30-year retirement is prudent, not pessimistic.
- Social Security's long-term picture remains uncertain. The 2026 Trustees report projects continued funding pressure; financial planners broadly recommend building savings that could support retirement independently of Social Security.
- Target-date funds matured. They're now the default choice in most 401(k) plans and represent a sound, low-maintenance approach for the bulk of retirement savings.
- Inflation awareness increased. Post-2022 inflation reminded savers that a retirement income that looks adequate today may feel different in 15 years — inflation-adjusted planning matters.
The core rules of thumb
The 15% rule: Save 15% of your gross income for retirement, including employer match. This is the most widely validated benchmark for a career-spanning savings rate that produces a comfortable retirement for most workers.
The 4% rule: In retirement, you can withdraw ~4% of your portfolio per year and expect it to last 30 years historically. This means: your retirement savings target = annual retirement spending × 25.
Example: If you expect to spend $60,000/year in retirement, you need roughly $1.5 million ($60,000 × 25).
Age-based savings benchmarks
These are targets as a multiple of your current salary — useful checkpoints, not pass/fail grades:
| Age |
Savings target (multiple of salary) |
| 30 |
~1× annual salary |
| 35 |
~2× annual salary |
| 40 |
~3× annual salary |
| 45 |
~4–5× annual salary |
| 50 |
~6× annual salary |
| 55 |
~7× annual salary |
| 60 |
~8× annual salary |
| 65 |
~10× annual salary |
These assume retiring at ~65 with Social Security as a supplement. If you want to retire earlier or expect no Social Security, the multiples increase.
How to estimate your actual retirement number
- Estimate your annual retirement spending. Use 70–80% of your current pre-retirement gross income as a starting point (expenses typically decrease in retirement). Adjust up if you plan extensive travel; adjust down if you expect a paid-off home.
- Subtract predictable income sources. Estimate your Social Security benefit (check ssa.gov for your projection), any pension, or other guaranteed income. Your savings need to cover the gap.
- Multiply the gap by 25 (the 4% rule). That's your savings target.
- Inflate for time. If you're 25 years from retirement, that number needs to grow; your investments will compound, but your target also rises with inflation.
How to get on track if you're behind
| Gap type |
Action |
| Small savings rate |
Increase by 1–2% per year until you hit 15% |
| Late start |
Catch-up contributions (age 50+); work additional years; reduce expected spending |
| High expense ratios |
Switch to low-cost index funds inside your 401(k) |
| No employer match |
Prioritize maxing IRA + increasing contributions |
| Variable income |
Percentage-based saving; a windfall savings rule (save X% of any bonus) |
How to pick a savings approach
- Capture the full employer 401(k) match first — guaranteed return beats all alternatives.
- Max a Roth IRA if eligible ($7,000/year in 2026) for tax-free growth.
- Return to the 401(k) and increase contributions toward the annual limit ($23,500 in 2026).
- Taxable brokerage for anything beyond those limits.
Common mistakes
Anchoring on a round number without context. "I need a million dollars" is only useful if you know what you'll spend in retirement. A couple spending $40,000/year needs $1M. One spending $80,000/year needs $2M.
Ignoring investment returns on current savings. Your existing balance compounds. A retirement calculator (use one from your brokerage) shows projected future value — don't ignore it.
Counting on Social Security as a primary income source. Treat it as a bonus. Build savings that could fund retirement independently, and anything from Social Security adds margin.
Stopping contributions during market downturns. Downturns are when you buy more units at lower prices. Stopping contributions during a drop is one of the most reliable ways to underperform.
What to skip
- Complex alternative investments in your retirement accounts. A total market index fund or target-date fund handles the hard work; exotic alternatives add fees and complexity.
- Paying for expensive actively managed funds inside your 401(k). Check expense ratios; anything above ~0.50% in a retirement account deserves scrutiny.
- Delaying retirement savings to pay off a low-rate mortgage first. The math usually favors investing simultaneously when mortgage rates are below historical stock returns.
FAQ
What if I'm starting at 40 with almost nothing saved?
Maximize contributions immediately, especially catch-up contributions at 50. You may need to work a few years longer and plan a slightly leaner retirement — but it's recoverable. The worst move is continuing to delay.
Does the 4% rule still hold?
It's a guideline, not a guarantee. Some planners use 3.5% for longer retirements or uncertain markets. The key insight is that you need a large enough portfolio that withdrawals are a small percentage of it.
Should I prioritize retirement savings or paying off debt?
High-interest debt (credit cards, personal loans) should typically be addressed simultaneously with at minimum capturing the employer match. Low-interest debt (mortgage) can generally run alongside retirement saving.
Can I retire early with this framework?
Early retirement requires a larger multiple (you need more savings and fewer working years). FIRE (Financial Independence, Retire Early) planning typically targets savings rates of 40–60% and spending-based portfolio sizes of 30–40× annual expenses.
