This calculator models a single holding under entered dividend, price, tax, contribution and purchase assumptions. It does not select investments, promise payouts or model actual eligibility and settlement dates.

The Dual Compounding Effect

Price changes before each period-end dividend. Dividends use opening shares and tax is withheld before allocation. Contributions buy afterward. Choose fractional or whole shares and an optional fee per executed purchase.

Growth rates and presets are editable illustrations, not quotes, forecasts or promised payouts. A dividend cut can reduce income to zero.

Tax Considerations for DRIP Investors

The entered taxable-account rate is withheld from each dividend before reinvestment or distribution; it is not charged again from external cash. Purchase fees are modeled separately. Sale and withdrawal taxes, foreign rules and taxable purchase-discount benefits are excluded. Other account labels mean no current dividend withholding in this model, not a complete tax forecast.

Economic value equals securities plus cumulative net cash distributions and both residual cash pools. Cash earns 0%. Reinvested dividends are already in shares. Gain uses all external capital as its denominator; it is not CAGR or IRR.

Purchase policy and residual cash

For each separate dividend or contribution pool, retain all cash when no purchase can execute. Otherwise deduct its fee and buy fractional shares or the largest whole number affordable. Carry the remainder forward. A dividend discount applies only to dividend purchases.

Read the comparison on a consistent basis

The growth chart compares selected reinvestment with a 0% counterfactual using the same market, tax, fee, share-policy and contribution assumptions. Economic view includes all cash; securities-only view excludes it. Scenario overrides are explicit. None of these illustrations measures diversification, risk or investment suitability.
