How Much Should I Save Each Month? (By Income and Age)
The Quick Answer
Save 20% of gross income. That figure comes from decades of retirement math and roughly matches the "20" in the 50/30/20 rule. It splits like this:
- 10–15% to long-term retirement (401(k), IRA, HSA).
- 5–10% to shorter-term savings (emergency fund, down payment, sinking funds).
If 20% feels impossible today, start at any positive number and raise 1% every pay raise. Most people hit 20% within 5 years without noticing.
By Income
Rough monthly targets (savings + investing combined):
| Gross monthly income | 10% (starter) | 20% (target) | 25% (aggressive) | |---|---|---|---| | $3,000 | $300 | $600 | $750 | | $5,000 | $500 | $1,000 | $1,250 | | $7,500 | $750 | $1,500 | $1,875 | | $10,000 | $1,000 | $2,000 | $2,500 | | $15,000 | $1,500 | $3,000 | $3,750 |
Higher incomes should push toward 25–30% because fixed costs scale slower than income. If you earn $250k and only save 15%, lifestyle inflation is quietly eating the rest — see lifestyle creep explained.
By Age (If You're Starting Late)
Age matters because compounding needs runway. Rough savings rates required to hit a normal retirement, assuming 7% real returns and 45% income replacement:
| Age you start | Required savings rate | |---|---| | 25 | ~12% | | 30 | ~15% | | 35 | ~20% | | 40 | ~28% | | 45 | ~40% | | 50 | ~55% |
Every 5 years you wait, the required rate goes up roughly 5–7 percentage points. That's the math that makes people mad at their 22-year-old selves.
By Life Stage
Right after college: Build a $1,000 starter emergency fund → capture 401(k) match → attack high-interest debt. Actual savings might be 5–10% while you catch up. Fine.
20s (no debt): 15–20% total, weighted toward Roth accounts. Time in the market is your unfair advantage — see how to build wealth in your 20s.
30s (mortgage + kids): 15–20% still, plus separate sinking funds for the annual expenses that show up as "emergencies" if you don't plan them.
40s–50s (peak earning): 25–35%. This is when 401(k) catch-up contributions kick in at 50 — use them.
Late 50s+: Shift priorities from accumulation to sequence-of-returns risk. Read the bucket strategy.
Where the Savings Should Go (Order of Operations)
- $1,000 starter emergency fund in a high-yield savings account.
- Full 401(k) match — see contribution limits.
- High-interest debt payoff.
- 3–6 month emergency fund.
- Roth IRA to $7,000.
- HSA to max.
- 401(k) to $24,000.
- Taxable brokerage for anything left.
That order maximizes the return on each dollar. Don't invest before killing 22% APR credit card debt.
The Only Number That Matters
Your savings rate — not your salary, not your net worth, not your investment returns — is the single strongest predictor of retirement age. Two people earning the same, one saving 10% and one saving 25%, retire 17 years apart. That's the leverage.
