Compound Growth Formula

A = P(1 + r/n)^(nt)
Where:
A = Final amount
P = Principal
r = Annual growth rate
n = Compounding frequency
t = Time in years

Growth Examples

Investment Growth
$10k at 8% for 20 years
Business Revenue
$100k at 15% for 10 years
Savings with Contributions
$5k + $500/month at 6%

Real Estate: 3-6%
Small Business: 10-25%
Tech Startups: 20-50%
Population: 1-3%

Understanding Compound Growth

Compound growth occurs when growth builds upon previous growth, creating an exponential effect over time.

  • Exponential Nature: Growth accelerates over time
  • Compounding Effect: Earnings generate their own earnings
  • Time Advantage: Longer periods amplify results
  • Rate Sensitivity: Small rate differences have big impacts
