This chart visualizes the power of dividend reinvestment over time. The green line shows portfolio growth with DRIP, the blue line shows growth without DRIP, and the gray dashed line represents your total contributions.
Year-by-Year Results
Yield on cost = dividends reinvested in that year ÷ total contributions so far. It shows how much income your original money is producing, and it rises over time even when the dividend yield you entered stays the same.

Monthly vs Quarterly vs Annual Reinvestment
Same inputs, different reinvestment frequency — recomputed live from your settings above.
| Reinvestment frequency | Final value (with DRIP) | Total dividends reinvested |
|---|---|---|
| Monthly (12x/year) | $207,823.45 | $57,810.77 |
| Quarterly (4x/year) | $205,530.94 | $56,757.46 |
| Annual (1x/year) | $195,887.82 | $52,326.84 |
Default assumptions (editable): 4% dividend yield, 8% annual return, 15% tax rate. These are scenario inputs, not market data or a forecast. Realty Income (O) pays monthly — $0.2715 per share as of November 2026, about a 5.6% yield; JEPI also pays monthly with a variable yield around 7–8%. Your actual yield will differ.
How Monthly DRIP Works
What Is Monthly DRIP?
Most dividend stocks pay quarterly, but a growing set of funds and REITs pay monthly — Realty Income (O), JEPI, and many others. With monthly DRIP, every dividend is reinvested within weeks of being paid, so each payment starts earning its own dividends sooner. The mechanics are identical to quarterly DRIP; only the timing changes.
Monthly vs Quarterly: How Big Is the Difference?
Small — but real. Under the default assumptions ($10,000 start, $300 a month, 8% return, 4% yield, 20 years, 15% tax), monthly reinvestment ends at $207,823 versus $205,531 quarterly — about $2,293 more, or 1.12%. The gap grows with higher yields and longer horizons, and shrinks when yields are low. The table below recomputes the comparison live from your inputs, using this site's own DRIP engine.
Why This Page's Numbers Differ from the Homepage Calculator
The homepage calculator reinvests once a year, so the same inputs give a lower result ($195,888 under the default assumptions) — contributions and dividends wait up to a full year before compounding. This page reinvests 12 times a year, so money starts compounding sooner. Neither is wrong; they are different timing assumptions. Use this page when your holdings actually pay monthly, and the homepage when they pay annually or you want the simpler annual model.
