MONTHLY GROSS EQUIVALENT
$74

$887 annual gross · $222 quarterly equivalent · $74 monthly after tax.

At the end of year 20; actual gross dividends during that year: $865.

Reinvestment / DRIP impact 100% vs 0% · $12,167 portfolio difference

All other inputs are identical. Difference = selected DRIP minus alternate. Retained cash remains separate from the portfolio.

Portfolio = initial investment + recurring contributions + reinvested dividends + share-price change. Price change is accumulated monthly on shares held during each price movement. It is not inferred from a residual. Cash is excluded; gross dividends already include both reinvestment and cash before tax, so adding them again would double count.

Contributions buy fractional shares at period start. Price and raw annual dividend grow monthly at (1 + annual rate)^(1/12) − 1. The optional cap limits effective annual dividend to price × cap each month; raw dividend growth continues independently. Generic period-end payments equal shares × effective annual dividend / payments per year. Flat tax is deducted before DRIP; retained cash earns no interest and is excluded from portfolio value. Inflation discounts only ending portfolio value. Fees and capital-gains taxes are excluded.

At the end of year 20, $887 annual gross run-rate ÷ 12 = $74 monthly equivalent. This differs from the $865 actually simulated during that year. Yield on contributed capital divides the ending annual run-rate by external contributions; reinvestment is excluded from its denominator.

Contributions in each row exclude the initial investment. Income columns are the year-end gross run-rate; dividends are actual simulated payments within that year.

Educational estimates from manual inputs. Dividends, prices, and taxes can change. Not investment advice or guaranteed income.

The formula

New shares per payment = gross dividend × (1 − tax rate) × reinvestment rate ÷ payment-date share price.

A worked example

$10,000 at 4% yield, quarterly payments, full DRIP, and no growth, contributions, or tax ends one year at $10,406.04: $10,000 × 1.01⁴. With no DRIP, the portfolio stays at $10,000 and $400 is retained as cash.
