Assume a constant share price and dividend. Compare the shares bought with dividends and the cash left over.
Quantity, dividend, tax rate and currency were copied from your previous calculation. Confirm that the dividend is for one payment and choose its frequency. Enter a new assumed share price. This does not imply that any reported dividend will recur.
1. Calculation inputs
Enter the share price and dividend in the selected currency. Changing currency does not convert amounts.
Enter the dividend for one payment, not the annual total. If you only know the annual total, first check the actual payment frequency and amounts.
Enter your own tax assumption. A 0% rate means no tax is deducted in this model; it does not determine tax-exempt status.
Shared URLs include your inputs.
2. Same assumptions, two outcomes
Enter shares, price, dividend and payment assumptions to compare both outcomes.
Total assets with reinvestment
Total assets with cash held
Difference in total assets
Total assets = share value + remaining cash. Cumulative dividends are not added again.
Assumed dividend payments:
Cash earns no interest and reinvestment has no fees in this model. Losses from changing share prices or dividends are not modeled.
Breakdown of shares and cash
Both scenarios use the same initial shares, share price, dividend, tax rate and period.
Item
Hold cash
Dividend reinvestment
Cumulative net dividends include money already spent on shares. They are different from remaining cash.

Displayed amounts are rounded to whole won or two decimal places for dollars. Cash and tax are not rounded during calculation, so actual payments and withholding may differ. Rounded components may not add up to the displayed total.
How each dividend payment is calculated
Net dividend = shares before this payment × dividend per share per payment × (1 − tax rate ÷ 100).
Add the dividend to cash carried forward, then buy as many whole shares as possible at the assumed share price.
Cash insufficient to buy one share is carried forward. Newly bought shares start receiving dividends from the next payment.
The first dividend arrives after one selected period, and the last payment is also reinvested. Share price and dividend per share remain constant. Ex-dividend price adjustments, additional contributions, trading fees, taxes on sale and exchange-rate changes are excluded.
This is an arithmetic comparison of your assumptions, not a return forecast or investment recommendation. Investing cash dividends elsewhere is also outside this comparison.
The compound interest calculator grows an amount at a constant return. This tool instead tracks whole shares affordable at each dividend payment and remaining cash. It does not model share-price appreciation or dividend growth.
