Whether you're aiming for $500 a month to cover a car payment or $2,000 to replace a significant chunk of your salary, the question is always the same: how much capital does it actually take? The answer depends almost entirely on one number most people get wrong — your net yield.
This guide gives you both the quick benchmarks and the realistic, after-tax numbers. We'll show you exactly how taxes and fees inflate your capital requirement, and how to use DCSimulator to build a plan that survives the real world.
"Inflation is taxation without legislation." — Milton Friedman
Capital required = (Monthly income target × 12) ÷ net yield
Net yield = gross yield × (1 − tax rate) − expense ratio
Example: For $1,000/month at 2.78% net yield → $12,000 ÷ 0.0278 = $431,655
Table 1: Capital Required at Gross Yield (Before Taxes & Fees)
This first table uses gross yield — a useful quick reference, but not what you should plan your financial life around. Think of it as the starting point of the conversation.
| Monthly Target | 2.5% Gross | 3.0% Gross | 3.5% Gross | 4.0% Gross |
|---|---|---|---|---|
| $500/mo ($6,000/yr) | $240,000 | $200,000 | $171,429 | $150,000 |
| $1,000/mo ($12,000/yr) | $480,000 | $400,000 | $342,857 | $300,000 |
| $1,500/mo ($18,000/yr) | $720,000 | $600,000 | $514,286 | $450,000 |
| $2,000/mo ($24,000/yr) | $960,000 | $800,000 | $685,714 | $600,000 |
Table 2: Capital Required at Net Yield (After 15% Tax + 0.20% Fund Fee)
This is the table that matters. Here we apply a 15% qualified dividend tax rate and a 0.20% expense ratio — typical for a portfolio of low-cost dividend ETFs in a taxable U.S. brokerage account. These are the numbers you should plan around.
| Monthly Target | 1.93% Net (2.5% gross) |
2.35% Net (3.0% gross) |
2.78% Net (3.5% gross) |
3.20% Net (4.0% gross) |
|---|---|---|---|---|
| $500/mo | $311,139 | $255,319 | $215,827 | $187,500 |
| $1,000/mo | $622,278 | $510,638 | $431,655 | $375,000 |
| $1,500/mo | $933,417 | $765,957 | $647,482 | $562,500 |
| $2,000/mo | $1,244,556 | $1,021,277 | $863,309 | $750,000 |
Compare the two tables closely. At a 3.5% gross yield, the gross table suggests $342,857 for $1,000/month. The net table reveals you actually need $431,655 — a gap of nearly $89,000 that most investors never account for.
How Much Capital Needed for $2,000 Monthly Dividend Income?
Using the net-yield table above, $2,000/month requires roughly $750,000 to $1,244,556 depending on your net yield. For example, at 2.35% net yield the target is $1,021,277, while at 2.78% net yield it's about $863,309.
How Much Can You Make in Dividends With $100,000?
If your starting portfolio is $100,000, your dividend income is simply capital × yield. Below are common yield assumptions, plus a realistic net-yield example using the same inputs as Table 2 (15% tax + 0.20% fund fee).
| Gross Yield | Monthly Dividends (Gross) | Net Yield Example (15% tax + 0.20% fee) |
Monthly Dividends (Net) |
|---|---|---|---|
| 2.5% | $208 | 1.93% | $161 |
| 3.0% | $250 | 2.35% | $196 |
| 3.5% | $292 | 2.78% | $232 |
| 4.0% | $333 | 3.20% | $267 |
Reminder: yields move with price and distributions. Use this as planning math, then verify the current yield for the specific ETF(s) you hold.
Why Net Yield Is the Only Number That Matters
A 4% gross yield looks incredible on a screener. But your net yield — what you keep after taxes and fees — is all that pays your bills. Here's how the formula works in practice:
Gross yield: 3.5% | Tax rate: 15% | Fund expense ratio: 0.20%
Net yield = 3.5% × (1 − 0.15) − 0.20% = 3.5% × 0.85 − 0.20% = 2.975% − 0.20% = 2.78%
At a higher tax bracket (25%): Net yield = 3.5% × 0.75 − 0.20% = 2.43%
That 10% tax difference adds $54,000 to the capital needed for $1,000/month.
How Long Will It Take? Monthly Savings Projections
Knowing your capital target is step one. Step two is figuring out how long it takes to get there. The table below assumes a conservative 7% annual total return (capital appreciation + reinvested dividends) — a reasonable long-term expectation for a diversified equity portfolio.
| Monthly Savings | $500/mo target ($216K needed) |
$1,000/mo target ($432K needed) |
$2,000/mo target ($863K needed) |
|---|---|---|---|
| $500/month | ~18 years | ~26 years | ~35+ years |
| $1,000/month | ~12 years | ~19 years | ~27 years |
| $1,500/month | ~9 years | ~15 years | ~22 years |
| $2,000/month | ~7 years | ~13 years | ~19 years |
DCSimulator shows you this exact projection — including the gap between where your current savings rate takes you and your P75 capital target. Adjusting your monthly contribution by even $200 can shave years off the timeline.
How to Model Your Own Path in DCSimulator
Benchmarks are a starting point, but your financial plan should be uniquely yours. Here's a step-by-step approach:
- Desired monthly income: Enter the after-tax amount you actually need to live on — not a vanity number
- Time horizon: Are you planning for 5 years or 25 years? This dramatically changes the math
- Yield & Growth estimates: Use the sliders to test optimistic, realistic, and pessimistic scenarios
- Taxes & Fees: Be brutally honest. These directly reduce your net yield and inflate your capital requirement
- Inflation: The simulator automatically adjusts your income target over time to preserve purchasing power

Choosing Your Safety Level: P50 vs P75 vs P90
When you run the simulation, you won't get a single number. You'll get a range of percentiles representing different confidence levels for the capital you might need:
- P50 (The Median): Half of simulated scenarios need more, half need less. Useful context, but too fragile for retirement planning.
- P75 (The Prudent Anchor): Our recommended planning baseline. You're protected against most adverse scenarios without over-saving.
- P90 (The Fortress): Your ultimate stress-test. If your plan holds here, you can weather a hostile decade of low growth and high inflation.
⚠️ Risks & Limitations
- Yield compression: Yields can decline across the market as valuations rise. A 3.5% yield today might become 2.5% in a bull market, forcing you to invest more capital.
- Dividend cuts: Individual companies — even long-term dividend payers — can and do cut dividends during recessions. Diversification is your primary defense.
- Tax law changes: The current 15% qualified dividend rate isn't permanent. Higher future tax rates would reduce your net yield and increase capital requirements.
- Inflation risk: If dividend growth trails inflation for an extended period, your purchasing power declines even as nominal dividends stay flat.
- Sequence risk: Poor early returns on a new portfolio can permanently impair your timeline. Start conservative and stress-test aggressively with DCSimulator.
Key Takeaways
- Gross yield tables understate required capital by 15–30%. Always plan with net yield.
- For $1,000/month at 2.78% net yield, you need ~$432,000 — not the $343K gross tables suggest
- Higher savings rates compress your timeline dramatically — $200/month extra can save 3+ years
- Plan around DCSimulator's P75 percentile; check P90 for worst-case resilience
- Run the simulator with your actual tax rate and fees for personalized results
