Saving $1 Million: The Math, the Timeline, the Strategy

A million dollars used to be the default 'rich' number. Adjusted for inflation it's not what it once was — but it's still enough to retire comfortably in most US zip codes, and it's still the most-searched savings target on the internet. Here's exactly what it takes.

The four-variable equation

Time, monthly contribution, expected return, and starting balance. Change any one and the others move. The Savings Goal Calculator solves for whichever variable you leave blank.

Time to $1M at different contribution rates

Assuming 7% average return (a conservative invested portfolio):

• $500/month: ~36 years
• $1,000/month: ~26 years
• $1,500/month: ~21 years
• $2,000/month: ~18 years
• $3,000/month: ~14 years
• $5,000/month: ~10 years

The 'just start' principle

Someone who saves $500/month from age 25 to 65 ends with roughly $1.2M at 7%. Someone who saves $1,000/month from age 40 to 65 ends with roughly $810,000 — saving twice as much for nearly as long and falling short. Time is the most powerful variable in the equation. Start with whatever you can, today.

Pure cash vs. invested

Hitting $1M in pure cash (4.4% APY) requires roughly $1,650/month for 30 years or $4,000/month for 15 years. Hitting it through invested savings (7% return) requires roughly $1,200/month for 30 years or $3,200/month for 15. The market risk is the price of the shorter timeline.

Account stacking the right way

Order of operations: 401(k) up to employer match, HSA if eligible, Roth IRA up to limit, 401(k) up to limit, taxable brokerage. Roughly 70% of millionaires built their net worth through tax-advantaged accounts before touching taxable savings. The order matters more than the products.

What income level makes it realistic

$1M in 20 years at 7% requires $1,920/month — about 23% of gross income on a $100,000 salary. At household income above $150,000, the math gets dramatically easier. Below $80,000, plan for a longer timeline or aggressive side income — not impossible, just slower.

What $1M actually pays

Using the 4% rule, $1M produces about $40,000/year of inflation-adjusted income — roughly $3,330/month. Combined with Social Security (~$2,000/month for a median earner), that's a comfortable retirement in low-to-medium cost-of-living areas, modest in high cost-of-living metros.

Build the plan today

Run $1,000,000 with your real timeline and assumed return in the Savings Goal Calculator. The number that comes back is the monthly contribution that turns a wish into a date on the calendar.
