"Save more" is universal financial advice. "Save enough" requires math. Most people have a vague sense that they should be saving more, but no concrete idea of whether what they're doing now is on track, behind, or ahead. This guide gives you both the standard benchmarks and the framework to calculate your own personal sufficiency number.
The Standard Benchmarks (and What They Actually Mean)
The 20% Rule (50/30/20)
The most widely cited savings benchmark: save 20% of gross income, split across emergency fund, retirement, and other goals. The 50/30/20 budget allocates 50% to needs, 30% to wants, and 20% to savings and debt payoff.
When it works: Starting in your 20s with no existing savings and standard retirement goals.
When it falls short: Starting late, or targeting early retirement, or living in a high cost-of-living area where 50% needs is impossible.
The 15% for Retirement Rule
Fidelity and Vanguard both suggest saving 15% of gross income for retirement (including employer match) as a general target. This assumes you start at 25, retire at 67, and want to replace 45% of pre-retirement income from savings (with Social Security covering the rest).
| If You Start Saving at... | Target Savings Rate for Retirement |
|---|---|
| 25 | 15% (including match) |
| 30 | 18% |
| 35 | 23% |
| 40 | 30%+ |
| 45 | 40%+ (very aggressive saving required) |
Starting 10 years late roughly doubles the required savings rate. Compound interest is generous to early starters and punishing to late ones.
The Savings Milestone Benchmarks (Fidelity)
Age-based savings milestones give you a checkpoints-based way to assess retirement track:
| Age | Retirement Savings Target | On a $75,000 Salary |
|---|---|---|
| 30 | 1× annual salary | $75,000 |
| 40 | 3× annual salary | $225,000 |
| 50 | 6× annual salary | $450,000 |
| 60 | 8× annual salary | $600,000 |
| 67 | 10× annual salary | $750,000 |
These are rough guides, not precise targets. They assume Social Security covers a significant portion of retirement income and that you'll spend about 55–80% of pre-retirement income in retirement.
The Right Way to Know If You're On Track
Benchmarks tell you where the average person should be. Your number depends on your specific situation. Here's how to calculate it:
Step 1: Define your retirement target
Use the framework from How Much Do You Actually Need to Retire?: estimated annual spending minus Social Security minus any pension income, multiplied by 25 (4% rule). This gives your required portfolio at retirement.
Step 2: Project what you'll have with current savings rate
Open the Retirement Calculator and enter your current balance, monthly contribution (including employer match), expected return, and years to retirement. The projected balance is what you'll have if you continue exactly as you are now.
Step 3: Compare projected to required
If projected ≥ required: you're on track. If projected < required: you have a gap. The gap tells you exactly how much additional monthly saving is needed ??? run the calculator again with different contribution amounts until the projected balance hits your target.
Projected balance at 65: ~$1,240,000
Required portfolio (spending $70k/year − $32k SS = $38k from portfolio × 25): $950,000
Result: On track ??? with $290,000 of buffer. This person could reduce contributions temporarily if needed, or retire earlier.
Beyond Retirement: Am I Saving Enough for Everything?
Retirement isn't the only thing you're saving for. A complete savings picture includes:
| Goal | Savings Status to Aim For |
|---|---|
| Emergency fund | 3–6 months of expenses fully funded in HYSA |
| Employer 401(k) match | Contributing enough to capture 100% of match |
| High-interest debt | Zero balances above ~7–8% APR |
| Near-term goals (1–3 years) | Dedicated account with monthly contributions on calculator-verified track |
| Retirement | On track per your personal projection (see above) |
If all five are green, you're saving enough. If any are red, that's where your next savings dollar should go ??? in roughly the priority order shown.
Signs You're Falling Behind
- Your retirement savings are below the age-based milestones by more than one income multiple and you're not compensating with a higher savings rate
- You don't have an emergency fund ??? every unexpected expense goes on credit, preventing savings from accumulating
- You're not capturing the full employer match ??? declining free money is the clearest sign of insufficient saving
- Your savings rate hasn't increased as your income has increased ??? lifestyle inflation consuming every raise is a common trap
- You've run the retirement calculator and there's a significant gap ??? the math doesn't lie
The One-Number Test
If you want a single quick test: take your total monthly savings (401k + IRA + HYSA + other dedicated savings, including employer match) and divide by your gross monthly income. If that number is below 15% and you're under 40, you probably need to save more. If it's above 20%, you're almost certainly on track unless you started very late or have an unusually expensive retirement target.
