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.
