An investor with a long-term dividend portfolio wants to replace part of salary income with passive cash flow.

1. The investor enters portfolio value, dividend yield, contribution rate and tax assumptions.
2. The calculator estimates gross and net yearly dividends.
3. A DRIP scenario shows how reinvestment changes future portfolio value.
4. A FIRE calculator checks whether the projected income covers target expenses.
