Monthly Contribution Growth
What if you add $500/month on top of your starting amount?
Starting with $0, investing $500/month:
| Rate | 10 Years | 20 Years | 30 Years |
|---|---|---|---|
| 5% | $77,641 | $205,517 | $416,129 |
| 7% | $86,541 | $260,464 | $610,729 |
| 10% | $102,422 | $379,684 | $1,130,244 |
At 7% for 30 years, you contribute $180,000 but end up with $610,729 — compound interest adds $430,729 on top of your deposits.
Key Observations
- The rate matters less for short periods — 5% vs 10% over 5 years is only a $4,000 difference on $10K
- The rate matters enormously over long periods — the same comparison over 30 years is a $154,000 difference
- Regular contributions dominate — $500/month at 7% for 30 years beats a one-time $50,000 at 7% for 30 years ($610K vs $405K)
