What is a dividend calculator?
A dividend calculator projects how a portfolio of dividend-paying stocks or funds could grow when you keep investing and, optionally, reinvest the dividends. It combines three engines of growth: your own contributions, rising share prices and growing dividend payments.
This one works quarter by quarter, which matches how many U.S. companies and funds pay dividends. It is meant to show how the pieces interact, not to predict what any investment will do.
How dividends work
A dividend is a share of a company's profit paid to shareholders, usually in cash and often every quarter. The dividend yield is the yearly dividend divided by the share price. If a stock costs $100 and pays $3 per year, the yield is 3%.
Companies can raise, hold or cut dividends. Dividend growth is the rate at which the payment per share rises each year. A company that pays $3 now and grows 5% a year pays about $3.15 next year.
What DRIP means
DRIP stands for dividend reinvestment plan. Instead of receiving cash, each dividend buys more shares. Those new shares pay dividends of their own, so income and share count compound together. Choose No to see the cash-out version, where dividends are tallied separately and your share count stays the same apart from your monthly contributions.
How the calculation works step by step
- Convert the starting investment into shares at a share price of $100 (the price level does not change the percentages).
- Each quarter, add three months of contributions as new shares at that quarter's price.
- Pay a quarter of the year's dividend per share on every share held.
- With DRIP, buy more shares at the end-of-quarter price. Without it, add the cash to a running total.
- Raise the dividend per share and the share price at the start of each new year using your growth assumptions.
Yield on cost explained
Yield on cost compares your current yearly dividend income to the total amount you have invested. A stock bought at a 3% yield whose dividend doubles will pay roughly 6% of what you originally paid, even if the current market yield is still 3%. It is a useful measure of how much income your invested dollars generate, but it ignores share price changes, so treat it as one view among several.
Things that change real-world results
- Taxes: dividends are taxable in many accounts. Qualified dividends are generally taxed at lower rates than ordinary income, while IRAs and 401(k)s defer or avoid current taxes.
- Dividend cuts: a payment can be reduced or suspended.
- Share price volatility: real prices rise and fall instead of growing in a straight line.
- Fees: fund expense ratios and trading costs reduce returns.
- Inflation: a dollar of income in 20 years buys less than today.
Using the calculator wisely
Try several scenarios: lower growth, zero growth and a higher yield. Very high yields can signal risk, so check why a yield is high before relying on it. Compare DRIP and no-DRIP to see how much reinvesting contributes, and use conservative growth assumptions rather than the best past results.
