Dividends purchase additional shares
This projection grows the share price and dividend at the entered annual rate, pays the dividend, then uses that cash immediately to buy additional shares at the new price. The share count compounds alongside the assumed price and dividend growth.
A ten-year fractional-share illustration
Starting with 300 shares at $40 is a $12,000 position. With a $1.60 dividend and 5% yearly growth, the model reaches about 444 shares worth $28,934 after ten years because each annual payment purchases fractional new shares.
Reinvestment rarely happens exactly once a year
It assumes reinvestment happens once per year with no delay, commission, tax withholding, or uninvested cash. Many plans pay quarterly or on another schedule, and their purchase price can differ from the displayed market price.
Price growth and payment growth can diverge
Price growth and dividend growth are deliberately tied together here. In reality a company can increase one while the other falls, and a dividend can be reduced entirely; model a cautious rate rather than reading the default as a prediction.
Accumulation is different from current income
The calculator describes accumulation through automatic reinvestment. For the current cash income from a fixed number of shares, use the dividend-yield page; for a whole portfolio with regular deposits, use a retirement savings projection.
Account rules can reduce the reinvested amount
Fractional-share rules, withholding, account fees, and tax accounts materially change the ending balance. Treat the output as a scenario to compare assumptions, then consult the plan terms and your records before relying on an income estimate.
The purchase method changes the outcome
A reinvestment plan can purchase shares at an average price, at a date chosen by the administrator, or through a broker order. Those mechanics determine how closely an actual account follows this annual illustration. If the holding is in a taxable account, cash withheld for tax may mean fewer shares are reinvested than the gross dividend suggests.
More shares do not prove more wealth
Reinvesting can increase the number of shares even while the market value falls, because the dividend buys more units at a lower price. That outcome is not a contradiction. Check both ending share count and ending value, and avoid assuming that a growing share count proves that wealth is growing.
The new shares come from cash divided by price
In the first year, 300 shares paying $1.60 create $480 of gross dividend cash. At the assumed post-growth price of $42, that cash buys about 11.43 additional shares, making roughly 311.43 shares before the next cycle. Repeating that purchase is the source of the share-count growth. It is not a separate return added to price appreciation; the dividend cash is converted back into ownership.
Payment frequency changes the compounding clock
An annual model deposits one reinvestment purchase. A quarterly plan would create four smaller cash flows, each with a different purchase price and time to compound. If a quarterly $0.40 payment is reinvested at $39, $41, $38, and $42, the acquired shares differ from dividing the annual $1.60 by one average price. Use the annual result as a transparent scenario, not as a statement-level reconstruction.
Taxable accounts may not reinvest the gross dividend
A plan can withhold tax before cash reaches the reinvestment instruction. If $480 is reduced by 15%, only $408 is available to buy shares, so the first-year share addition at $42 is 9.71 rather than 11.43. Tax rules and withholding differ by account and investor, which is why the tool does not silently choose a rate. Enter a lower effective dividend only when that reflects the cash actually reinvested.
Separate total return from the assumed growth pair
The model grows price and dividend at the same 5% rate to make the moving parts visible. A real issuer can increase a dividend while the price falls, or cut a dividend while the price rises. Fees, spreads, fractional-share policy, and purchase dates also matter. Read the ending value as the consequence of the selected pair of assumptions, then compare it with plan records rather than treating it as a forecast.
Fractional shares avoid idle cash in the model
The projection permits fractional shares, so every dividend dollar is reinvested. A broker that permits only whole shares might leave some cash uninvested until a later payment. On a small position, that residual can be meaningful. Check the plan's fractional-share rule before expecting a statement to match the smooth modeled share count.
A cut has two consequences
If the annual dividend falls from $1.60 to $1.00, fewer dollars buy new shares; the income stream also changes. A price decline may make each dollar buy more shares but does not restore the lost cash automatically. Test a lower dividend and a separate lower price rather than assuming a single growth rate captures both risks.
Review the share count after each statement
A reinvestment projection is easiest to audit by comparing shares, gross dividend, withheld amount, purchase price, and residual cash one payment at a time. If a statement differs, the gap usually comes from date, tax, fee, or fractional-share treatment. Do not repair it by changing a long-term growth rate without identifying the transaction difference. The next account statement, not the projection, records the actual purchase price and number of shares acquired. Separate gross distributions from reinvested cash whenever a broker statement shows withholding or an account charge.
