The 15% Target
The broadly recommended savings rate for retirement is 15% of gross income per year, including any employer match.
This guideline assumes:
- Starting to save consistently in your mid-20s
- Targeting retirement around age 65
- A balanced portfolio with equity exposure growing at ~6–7% annualized long-term
- Social Security providing some income replacement in retirement
If you started saving late, plan to retire early, or want a more conservative projection, you need to save more than 15%.
What 15% Looks Like in Practice
| Gross Income | 15% Target | Your Contribution (if 4% match) | Employer Match |
|---|---|---|---|
| $50,000 | $7,500/yr ($625/mo) | $5,500/yr ($458/mo) | $2,000/yr |
| $70,000 | $10,500/yr ($875/mo) | $7,700/yr ($642/mo) | $2,800/yr |
| $100,000 | $15,000/yr ($1,250/mo) | $11,000/yr ($917/mo) | $4,000/yr |
| $150,000 | $22,500/yr ($1,875/mo) | $16,500/yr ($1,375/mo) | $6,000/yr |
Example assumes 4% employer match included in total.
The Two Tests
Test 1: Savings Rate Test
Add up all retirement contributions (your portion + employer match), divide by gross annual income:
(Your retirement contributions + employer match) ÷ gross income = savings rate
If this is 15% or above, you are saving enough by the rate metric.
Test 2: Balance Milestone Test
Check your current retirement balance against the age-based milestones:
| Age | Balance Target |
|---|---|
| 30 | 1× annual salary |
| 35 | 2× annual salary |
| 40 | 3× annual salary |
| 45 | 4× annual salary |
| 50 | 6× annual salary |
| 55 | 7× annual salary |
| 60 | 8× annual salary |
| 67 | 10× annual salary |
If you are meeting both tests, you are on track. If you are behind on the balance milestone but saving at 15%, you will likely catch up through compounding. If you are below both, that is the higher-urgency situation.
What Insufficient Saving Actually Costs
The gap between a 10% savings rate and a 15% savings rate, compounded over 30 years, is substantial.
$70,000 income, 30-year time horizon at 7% return:
| Savings Rate | Annual Amount | 30-Year Balance |
|---|---|---|
| 6% | $4,200 | ~$424,000 |
| 10% | $7,000 | ~$707,000 |
| 15% | $10,500 | ~$1,061,000 |
| 20% | $14,000 | ~$1,413,000 |
The difference between saving 6% and 15% over 30 years is approximately $637,000 in additional retirement wealth.
Common Reasons People Save Less Than They Should
- No employer match awareness: some employees contribute only enough to get the match, not realizing the match is part of the 15% target
- Student loans competing for the same money: legitimate constraint; at minimum, capture the full match while paying down high-rate debt
- Delayed start: starting a first job at 27 instead of 22 compresses the runway; more aggressive saving is needed to compensate
- CashAccount confusion: some people count their savings account balance when evaluating retirement readiness — only long-term invested assets count
If You Are Behind: The Escalation Strategy
The most behaviorally effective approach to increasing savings is automatic annual escalation:
- Set your current rate (say, 8%)
- Set it to increase by 1% per year automatically
- In 7 years you are at 15%
Many 401(k) plans support this through auto-escalation features. If yours does not, set a calendar reminder each January to manually increase your contribution by 1 percentage point.
