Monthly deposit to reach $100,000
Starting from zero, here's roughly how much you'd need to invest each month to hit $100,000, depending on your timeframe and average annual return:
| Timeframe | 5% return | 7% return | 9% return |
|---|---|---|---|
| 5 years | $1,470/mo | $1,397/mo | $1,326/mo |
| 10 years | $644/mo | $578/mo | $517/mo |
| 15 years | $374/mo | $315/mo | $264/mo |
| 20 years | $243/mo | $192/mo | $150/mo |
| 25 years | $168/mo | $123/mo | $89/mo |
| 30 years | $120/mo | $82/mo | $55/mo |
For example, to reach $100,000 in 20 years at a 7% return, you'd invest about $192/month. That's about $144/month more than reaching $25,000 on the same timeline.
Halfway there first: reaching $50,000 on the same 20-year, 7% plan takes about $96/month - exactly half the deposit, since this math scales linearly with the target.
Have a lump sum instead of a monthly budget? Investing $25,842 today, left untouched for 20 years at a 7% return, would also grow to about $100,000.
Reach your goal faster
- Time is your biggest ally — starting earlier slashes the monthly amount needed.
- Automate deposits so you never miss a month.
- Higher (but realistic) returns dramatically reduce what you must contribute.
Calculations use steady return assumptions and exclude taxes.
