Project your dividend income over any time horizon — combining current portfolio value, dividend yield, monthly contributions, and expected dividend growth into a year-by-year income forecast.
A $75,000 dividend portfolio at 4% yield pays $3,000 this year. At 6% annual dividend growth with $400/month reinvested, that same position could pay $9,800 in year ten — without any change in the yield percentage. The compounding is happening inside the dividend growth, not just the stock price. This calculator takes your current portfolio holdings — entered as individual positions with current price, shares, and annual dividend per share — adds monthly investment additions, applies an expected dividend growth rate, and projects annual dividend income year by year.
The yield-based inputs give you the present-day income snapshot. The dividend growth rate and monthly additional investment are what transform today's $4,200 in annual dividends into tomorrow's $8,700. Both the pace of your contributions and the quality of your dividend growth assumptions determine how quickly you reach an income target. The tool makes that trajectory visible on your actual numbers.
How dividend growth compounds income over time
Dividend income compounds in two distinct ways. First, dividend reinvestment — using dividend payouts to buy more shares — grows your share count and therefore your future dividend income without any new cash from your own pocket. Second, dividend growth — when companies increase their per-share dividend payment year over year — grows income on every share you already own, including the reinvested ones.
The Expected Dividend Growth Rate input captures the second mechanism. A portfolio holding companies with a historical 6–8% annual dividend growth rate is not just paying a fixed yield — it is generating income that doubles roughly every 9–12 years through growth alone. A portfolio holding slower-growing or fixed-rate securities may yield more today but generates less income growth over a decade. The calculator applies the growth rate annually to show how income evolves.
Monthly additional investment: the contribution lever that changes the trajectory
Monthly Additional Investment represents new cash you are adding to the portfolio each month. These contributions buy more shares at current prices, immediately increasing dividend income by the yield on the new purchase. A $500/month contribution into a 4% yielding portfolio adds roughly $20 per month in annual dividend income per month of contributions — $240 per year in new income for each year of consistent $500 contributions.
The interaction between contributions and growth is where projections become surprising. A $300/month addition on a $40,000 portfolio with 5% dividend growth does not just grow linearly — the growing income is being reinvested into a growing dividend base, and each contribution compounds from the day it is invested. By year 10, the portfolio may be generating 40–50% more income than the original portfolio alone, with contributions accounting for roughly half the difference.
Portfolio holdings input: yield as the starting point
Entering individual portfolio holdings — ticker or name, current price, shares held, and annual dividend per share — gives the calculator an accurate starting yield based on what you actually own. The tool calculates the current annual dividend for each position and sums them to produce your current total portfolio income. From there, it applies your growth rate and contribution assumptions to the forward projection.
If your portfolio is diversified across many positions, you can simplify by entering your total portfolio value as a single holding with a blended average dividend per share or yield. A $80,000 portfolio with a 3.8% weighted yield can be entered as a single position: $80,000 value, $3,040 total annual dividend. The year-by-year projection will be equally accurate using either the detailed or simplified entry approach.
Setting a realistic dividend growth rate assumption
Expected Dividend Growth Rate is the annualized rate at which your portfolio's per-share dividends will increase over time. Dividend growth aristocrats — companies with 25+ consecutive years of dividend increases — have historically grown dividends at 6–10% per year. REITs and utility stocks often grow at 3–5% per year. A blended portfolio might average 5–7% growth depending on sector composition.
For planning purposes, entering a conservative rate (4–5%) produces a credible worst-case projection; entering a historical average (6–8%) gives you a middle-of-the-road scenario. The gap between those two projections over 15 years can be substantial — a 4% growth rate versus a 7% growth rate on the same starting income doubles the 15-year income differential. Run both scenarios to understand your planning range.
Dividend income as a financial independence metric
Many dividend investors track annual portfolio income as a progress metric toward a specific monthly income target. If your current living expenses are $4,000/month and your portfolio currently generates $700/month in dividends, you are 17.5% of the way to dividend coverage of your expenses. The calculator projects when — at your current contribution and growth rate — portfolio income might reach a target threshold.
That timeline varies dramatically based on starting portfolio size, contribution level, and dividend growth rate. A $60,000 portfolio with $600/month additions at 6% dividend growth might project to cover $4,000/month in dividends in 18–22 years. A $200,000 portfolio with the same contributions reaches the same milestone much faster. Knowing the year your dividends are projected to cover the rent — a real month on a real calendar, not a vague 'someday' — is the kind of clarity that keeps the monthly contribution going when the market is ugly. Plug in your actual holdings, save the scenario, and check it against the projection each year as your income climbs.
How to use it

- Set Expected Dividend Growth Rate as an annualized percentage based on your holdings' dividend growth history.
- Read the current total annual dividend income and the year-by-year income projection.
- Adjust the growth rate and monthly contribution to model optimistic and conservative scenarios for your planning range.
Who it's for
- Investor projecting when dividends will cover monthly expenses — Enters a $75,000 portfolio at 3.9% yield with $400/month additions and 6% dividend growth — sees projected $2,800/month in dividend income in year 14, compared to their $2,400/month target.
- Dividend growth investor evaluating a yield versus growth trade-off — Compares a 5.5% yield portfolio with 3% growth against a 3.2% yield portfolio with 8% growth — finds the high-yield option produces more income for the first 9 years, then the high-growth portfolio overtakes it permanently.
- Near-retiree modeling income from an existing dividend portfolio — Enters their $320,000 portfolio holdings at a 4.1% blended yield with zero new contributions and 5% growth — sees $13,100 in year-1 income growing to $21,300 by year 10 without any additional investment.
- Investor setting a monthly contribution target to reach a specific income goal — Iterates on Monthly Additional Investment until the year-8 projected income reaches their $1,500/month target — finds $550/month contributions achieve the goal, versus $350/month taking 4 additional years.
Key terms
- Dividend yield
- Annual dividend per share divided by the current share price, expressed as a percentage. The starting income rate for a dividend investment at any given price.
- Dividend growth rate
- The annualized percentage by which a company or portfolio's per-share dividend payment increases. Companies that consistently grow dividends provide income growth that compounds over time.
- Dividend reinvestment (DRIP)
- The practice of using dividend payouts to purchase additional shares rather than taking the cash. Accelerates portfolio income growth by increasing share count without new capital contributions.
- Dividend coverage ratio
- A company's earnings per share divided by its dividend per share. A ratio above 1.5 indicates the dividend is well-covered by earnings and is unlikely to be cut; below 1.0 means the company is paying out more than it earns.
Frequently asked questions
Does the calculator assume dividend reinvestment?
The dividend growth projections assume dividends contribute to portfolio growth through reinvestment. If you plan to take dividends as cash rather than reinvesting, the income projection will be lower because the compounding mechanism is reduced. The most conservative planning approach treats dividend reinvestment as the base case and cash withdrawal as a separate scenario.
How do I enter a fund or ETF holding?
Enter the ETF's current share price, your share count, and the trailing 12-month annual dividend per share from the fund's distribution history. For blended funds, the effective dividend per share is the sum of the trailing year's per-share distributions. Most fund data sites publish this figure directly.
What dividend growth rate should I use for REITs?
REITs are required to distribute at least 90% of taxable income as dividends, which provides high yields but often limits growth. REIT dividend growth rates typically run 2–5% annually, with some specialized REITs growing faster. Use 3–4% as a conservative assumption unless you have specific growth data for your holdings.
Does this account for taxes on dividend income?
The projections show pre-tax dividend income. Qualified dividends in a taxable account are taxed at 0%, 15%, or 20% depending on income. Dividends in a Roth IRA are tax-free; in a traditional IRA they are taxed on withdrawal. To see after-tax income, reduce the projected figures by your expected dividend tax rate.
