How compound growth works
Compound growth means returns are earned on both the original principal and prior accumulated returns. Recurring deposits can accelerate growth, while withdrawals, taxes and inflation reduce the economic value of the final balance.
This calculator separates nominal future balance from inflation-adjusted value and shows the effective annual rate implied by the selected compounding frequency.
