Dividend Calculator

What this calculator does

This calculator projects dividend income from a stock position over multiple years. You enter your share count, the current annual dividend per share, an expected annual dividend growth rate, and a projection horizon. Optionally toggle DRIP (Dividend Reinvestment Plan) on or off and the tool shows the difference: cash dividends taken as income vs reinvested into more shares.

Output includes a year-by-year table of share count, annual dividend, cumulative dividend income, and ending portfolio value, plus a side-by- side comparison if DRIP is enabled.

How dividend projection works

The math is two iterative loops — one for each year — with the DRIP toggle swapping the rule:

Without DRIP, each year:

1. Annual dividend = shares × dividend-per-share
2. Add this year’s dividend to cumulative income
3. Next year’s dividend-per-share grows by the growth rate
4. Share count stays constant

With DRIP, each year:

1. Annual dividend = shares × dividend-per-share
2. New shares purchased = dividend ÷ current share price
3. Next year’s shares = old shares + new shares
4. Next year’s dividend-per-share grows by the growth rate
5. Share price also grows (the calculator assumes the same growth rate for share price — a simplification, see “How accurate is this?” below)

For a 1,000-share position paying $2/share with 6% annual growth over 20 years, the difference is striking: ~$73,500 cumulative dividends without DRIP vs ~$93,000 with DRIP, ending the period with ~1,820 shares instead of 1,000.

Dividend yield, total return, and the growth trap

Three pitfalls users typically run into:

High yield is not the same as high return. A stock paying 8% yield with -3% annual capital depreciation actually loses you money in total return. The 8% feels good in cash flow but the underlying capital is melting. Healthy high-yielders are rare — they exist (some REITs, some toll-road companies, some pipelines), but the average 8%+ yielder is a fading business propping up its dividend with debt.

Growth rate matters more than starting yield. Two stocks: A pays 4% and grows dividends at 3%/year. B pays 2% and grows at 10%/year. After 10 years, A pays effectively 5.4% on cost and B pays 5.2% on cost — roughly equal. After 20 years, A pays 7.2% but B pays 13.5%. The growth compounds. This calculator’s growth-rate input is the most sensitive parameter.

Cuts happen. The calculator assumes the growth rate continues indefinitely. In real life, even reliable dividend payers cut distributions during recessions (Wells Fargo cut 80% in 2020, ExxonMobil froze growth from 2015-2019, GE cut effectively to zero 2017-2018). The “Dividend Aristocrats” list (companies that have raised dividends 25+ years straight) is exactly that — a list of exceptions, not the average company.

Qualified vs ordinary dividends — US tax

US tax treatment is the other big surprise. Qualified dividends get long-term capital gains rates (0% / 15% / 20% depending on income). Ordinary dividends — including most REIT distributions, mortgage-REIT income, money-market dividends, and short-held positions — get ordinary income rates (10% through 37% under 2024 brackets).

For a top-bracket investor with $40,000 in annual dividend income, qualified vs ordinary can mean an $8,800 difference in annual tax. This calculator projects pre-tax dividends. For after-tax, take the projection and multiply by (1 - your effective dividend tax rate). The companion Tax Bracket Calculator in our suite can help size the marginal rate.
