Passive Income Portfolio Calculator

The spendable cash a portfolio pays without selling assets. Live passive income calculator with worked steps, charts.

Calculator

Portfolio Value Help
$

The invested portfolio the income or withdrawals come from.

Passive Yield(%) Help
%

Yearly cash yield — dividends, interest or rental yield on the portfolio.

Expected Annual Return(%) Help
%

Nominal yearly investment return before inflation. 7% is the long-run US stock average.

This net worth & wealth calculator runs on the standard FIRE model: yearly spending divided by a safe withdrawal rate sets the target, and savings compound monthly at the return you enter.

Formula

Multiplies the portfolio by its cash yield for spendable income today, then projects the portfolio forward to show how growth lifts future income.

Annual income = portfolio × yield

Alternative Form

Portfolio needed = desired income ÷ yield

Variables

Explanation

Yearly and monthly cash the assets produce at the entered yield, plus how growth lifts it over a decade.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Multiply the portfolio by its cash yield for the yearly passive income.

Income = portfolio × yield
Portfolio:$1,000,000
Yield:4.50%
Result: $45,000 per year
Step 2

Divide into a monthly figure you can compare with bills.

Monthly = annual ÷ 12
Annual:$45,000
Result: $3,750 per month
Step 3

Project the portfolio a decade forward to show how growth lifts future income.

FV = portfolio × (1+r)^n
Portfolio:$1,000,000
Growth:7.00%
Years:10
Result: $2,009,661 portfolio → $90,435/yr income
Final Answer
$45,000

Scenario

The passive income portfolio calculator run on the values above, showing the full calculation path rather than only the answer.

Inputs

Portfolio Value:$1000000
Passive Yield:4.5%
Expected Annual Return:7%

Calculation

1. Multiply the portfolio by its cash yield for the yearly passive income. → $45,000 per year 2. Divide into a monthly figure you can compare with bills. → $3,750 per month 3. Project the portfolio a decade forward to show how growth lifts future income. → $2,009,661 portfolio → $90,435/yr income

Result

Annual Passive Income: $45,000

Interpretation

Yearly and monthly cash the assets produce at the entered yield, plus how growth lifts it over a decade.

Understanding Your Result

Your Result: Annual Passive Income: $45,000

Typical range: Dividend portfolios yield 2–4%, rental property 4–8% after costs — compare yields only after subtracting fees and vacancies.

What This Means

Yearly and monthly cash the assets produce at the entered yield, plus how growth lifts it over a decade.

Why It Matters

$45,000/yr ($3,750/mo) at 4.50% on $1,000,000; ~$90,435/yr in a decade at 7.00% growth.

Professional Interpretation

$45,000/yr ($3,750/mo) at 4.50% on $1,000,000; ~$90,435/yr in a decade at 7.00% growth.

How this is calculated

Multiplies the portfolio by its cash yield for spendable income today, then projects the portfolio forward to show how growth lifts future income.

What drives the result

Yield is rent charged on capital: a 4% yield means every $100,000 of assets pays $4,000 a year. Higher yields usually mean higher risk, so sustainable passive income comes from a large base at a modest yield rather than a small base stretched for yield. Growth and income are two sides of the same coin — total return is what ultimately funds spending.

Recommendations

  • •Do not chase yield above ~6% without checking risk — high yields usually mean high danger.
  • •Reinvest income until the monthly figure covers a full spending category, then celebrate and repeat.

Educational Content

Introduction

Passive income is cash your assets pay you — dividends, interest, rent — without selling the assets themselves. This page turns a portfolio and a yield into the monthly income they produce, and shows how reinvested growth lifts that income over time.

Concept Explanation

Yield is rent charged on capital: a 4% yield means every $100,000 of assets pays $4,000 a year. Higher yields usually mean higher risk, so sustainable passive income comes from a large base at a modest yield rather than a small base stretched for yield. Growth and income are two sides of the same coin — total return is what ultimately funds spending.

Applications

▸Converting a portfolio into the monthly income it can pay
▸Sizing the portfolio needed to cover specific bills
▸Comparing dividend, interest and rental yields on equal footing
▸Projecting how reinvested growth raises future income

Benefits

  • •Expresses wealth as spendable monthly income, not an abstract lump
  • •Shows the yield-versus-risk trade-off numerically
  • •Links the income goal back to the portfolio goal that funds it
  • •Makes income milestones (cover groceries, cover rent) concrete

Limitations

  • •Yields move — dividends get cut and rental vacancies happen
  • •Chasing yields above ~6% usually means accepting serious risk of loss
  • •Tax treatment differs by income type and is not modelled here
  • •Inflation erodes fixed income unless the underlying assets grow

Best Practices

  • •Treat yields above 6% as guilty until proven innocent
  • •Reinvest income until it covers a whole spending category
  • •Hold 1–2 years of spending in cash so you never sell assets in a crash
  • •Diversify income sources the way you diversify assets

Common Misconceptions

Myth: Passive income means no work at all
Truth: Rentals need management, dividends need monitoring — "passive" means decoupled from hours, not free of attention.
Myth: A higher yield is always better
Truth: Falling prices push yields up, so the highest yields often signal the highest risk.

Practical Tips

  • •Treat yields above 6% as guilty until proven innocent
  • •Reinvest until income covers a full bill category
  • •Diversify income sources like asset classes
  • •Prefer growing payouts over high static ones

Common Mistakes

Chasing headline yield
Falling prices inflate yields — the highest payers are often the riskiest.
Ignoring total return
A 2% yield with 8% growth beats a 6% yield going nowhere.
Forgetting taxes
Income types are taxed very differently; compare after-tax figures.

Assumptions

This calculator makes the following assumptions to provide estimates:

Stable yield: The payout rate holds across the projection.
Yield on market value: Income scales with the portfolio figure entered.
Before-tax figures: Taxes on dividends, interest or rent are not deducted.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Yields move — dividends get cut and rental vacancies happen
Limitation: Chasing yields above ~6% usually means accepting serious risk of loss
Limitation: Tax treatment differs by income type and is not modelled here
Limitation: Inflation erodes fixed income unless the underlying assets grow

Frequently Asked Questions

Answers to common questions about this calculator.

Dividends, interest or rent — which is best?
Compare after costs, taxes and effort: a 4% dividend yield with no work often beats an 8% rental yield with weekends attached.
What yield is realistic?
Dividend portfolios 2–4%, bonds 3–5%, rentals 4–8% after costs. Above ~6% anywhere, check what risk you are being paid to take.
Should I reinvest or spend the income?
Reinvest until the income covers a whole spending category — then each milestone funds real freedom.
Who uses the passive income portfolio calculator?
It is used by savers planning independence, by advisers checking a client's number before big decisions, and by anyone tracking progress toward work-optional living. It sits in the Net Worth & Wealth group of the FIRE & Financial Independence section of Atlascalcs.
How accurate is the passive income portfolio calculator?
Every figure follows directly from the inputs using standard compounding and withdrawal mathematics, so it is accurate to the quality of the values you enter. Markets are volatile and inflation varies, so treat the output as a living plan and re-run it yearly with fresh figures.

Should I use nominal or inflation-adjusted returns?
This calculator uses the nominal return you enter. For spending power, either enter a real return (nominal minus ~2–3% inflation) or read long-horizon totals as nominal dollars that will buy less than today.
Does this account for taxes and fees?
Not automatically — lower the expected return by roughly your fee drag plus the tax bite (often 0.5–1.5 points combined) to approximate after-tax, after-fee results.
How often should I revisit my passive income plan?
Yearly, and whenever income, spending or the timeline changes materially. The inputs move slowly but compounding means small updates compound too.
