Portfolio Growth Calculator: Plan Your Wealth Journey

Our Portfolio Growth Calculator forecasts multi-asset portfolio value with contributions, returns, and inflation.

Why Model Portfolio Growth?

Visualize compounding across stocks, bonds, cash. Adjust for inflation to see real purchasing power.

Key Inputs

  • Initial Value: Starting balance
  • Contributions: Annual additions
  • Returns & Risk: Per asset class
  • Inflation: Real vs nominal

Asset Allocation Matters

60/30/10 portfolio: 8.1% expected return, ~9.5% risk.

Example: $50K + $12K/yr, 20 yrs

  • Nominal: ~$720,000
  • Real (3% inflation): ~$400,000
  • CAGR: 8.1% nominal, 5% real

Formulas

FV = PV × (1+r)^t + PMT × [((1+r)^t - 1)/r]

Real Value = Nominal / (1+inflation)^t
