How Long Does It Take to Reach $1 Million?
Reaching $1 million sounds far away — until you see the math. The exact timeline depends on three numbers: how much you save monthly, your average return, and your starting balance. This guide breaks down realistic paths to seven figures.
Quick answer
At a 7% return, saving $500/month reaches $1M in about 36 years. $1,000/month gets there in about 28 years. $2,000/month does it in about 21 years.
Years to reach $1 million by monthly contribution
Starting from $0, assuming a 7% average annual return:
- $200/month → about 46 years
- $500/month → about 36 years
- $1,000/month → about 28 years
- $1,500/month → about 24 years
- $2,000/month → about 21 years
- $3,000/month → about 17 years
- $5,000/month → about 12 years
Bump the return to 10% (long-term stock market average) and every line above shrinks by 5–8 years.
The three levers that change everything
1. Time
The most powerful lever, and the only one you can't get back. Starting at 25 vs 35 with the same monthly contribution roughly doubles your final balance.
2. Monthly amount
Doubling your monthly savings cuts the timeline by roughly 8–10 years. Increases here are the single fastest way to pull the goal closer.
3. Return rate
Going from a 4% savings account to a 7% diversified portfolio cuts the timeline by 30–40%. This is why long-horizon money usually goes into stocks rather than cash.
Realistic paths to $1M
The early starter
$500/month from age 22 in an index fund (assume 8%) → about $1.2M by 60. Total contributions: $228,000. The other ~$1M is compounding.
The late starter
Starting at 40 with $0 saved, you'd need about $1,500/month for 25 years at 8% to hit $1M by 65. Tougher but very doable.
The high earner
$3,000/month from age 30 in a balanced portfolio (7%) hits $1M in about 17 years — by age 47. Above-average income compresses the timeline dramatically.

Is $1 million still enough to retire on?
It depends on lifestyle and location, but $1M invested can generate roughly $40,000/year in retirement income (using the 4% rule), plus Social Security. For many people that's adequate; for others, especially in HCOL areas, $1.5–2M is a better target.
What rate of return is realistic?
For a long-term diversified stock portfolio, 7% real (after inflation) or 9–10% nominal is the historical average. Use 6–7% for conservative planning and don't assume more than 10%.
Does $1M include inflation?
If you use the 7% real return assumption above, yes — that's $1M in today's purchasing power. If you used 10% nominal, the $1M is in future dollars and worth less.
Should I aim for $1M in pre-tax or after-tax accounts?
Most people end up with both. A traditional 401(k) is pre-tax (you pay tax on withdrawals); a Roth IRA is after-tax (tax-free withdrawals). A blend gives you flexibility.
