Advanced Compound Interest Calculator

Project long-term portfolio growth with compounding, recurring contributions, inflation impact, and tax-adjusted returns.

Formulas Used

- Periodic Growth = Balance x (1 + r/n) with tax adjustment.
- Final Balance includes principal, contributions, and compounded net interest.
- Real Balance = Nominal Balance / (1 + inflation)^years.
- Effective Return is annualized after-tax growth rate.

Planning Notes

- Consistent contributions typically drive the largest long-term impact.
- Evaluate both nominal and inflation-adjusted balances.
- Tax drag can materially reduce effective annual return over longer horizons.
