$1,000,000 Goal at $2,000 a Month — Time to Goal, Worked Out
Saving $2,000.00 a month at a 7% annual rate (compounded monthly), you reach $1,000,000.00 in 235 months — about 19.6 years. Along the way you contribute $470,000.00 out of pocket and compounding adds $532,163.20. The calculator below is pre-filled with these numbers.
How the timeline is computed
each month: balance = balance × (1 + 7% ÷ 12) + $2,000.00
repeat until the balance reaches $1,000,000.00
Deposits land every month and interest compounds on the running balance, so progress is slow at the start and speeds up as the interest layer grows. That is $470,000.00 of contributions plus $532,163.20 of interest — compounding covered 53% of the goal.

Ways to arrive sooner
- Raise the monthly amount. The timeline responds faster to bigger deposits than to a higher rate.
- Start with a lump sum. Every dollar saved today is a dollar that compounds for the whole journey.
- Automate the transfer. Same-day-every-month deposits are the ones that actually happen.
- Keep the rate honest. Compare against the Compound Interest Calculator with different rates to see what a better account is worth.
1,000,000 美元目标、每月存 2,000 —— 达成时间全程演算
