How It Works
A = P(1 + r/n)^(n·t)
P = principal · r = annual rate · n = compounding per year · t = years
P = $10,000 · 5% · monthly (n=12) · 10 years
- 1A = 10,000(1 + 0.05/12)^(12×10)
- 2(1.004167)¹²⁰ ≈ 1.647
- 3A ≈ 10,000 × 1.647 = 16,470
Result: ≈ $16,470 — $6,470 of pure growth
Pro Tip
Start 5 years earlier and you could end up with ~30% more.
