Explanation

This is the capital that funds the target income sustainably.

Step-by-Step Calculation

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

Step 1

Divide the income goal by the sustainable yield.

Corpus = income ÷ yield%
Result: $1,000,000

Scenario

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

Inputs

Target Annual Passive Income:40000
Portfolio Yield:4
Saved Already:200000

Calculation

1. Divide the income goal by the sustainable yield. → $1,000,000

Result

Corpus Needed: $1,000,000

Interpretation

$40,000/yr at 4.00% needs $1,000,000 invested.

Understanding Your Result

Your Result: Corpus Needed: $1,000,000

What This Means

This is the capital that funds the target income sustainably.

Why It Matters

$40,000/yr at 4.00% needs $1,000,000 invested.

Professional Interpretation

$40,000/yr at 4.00% needs $1,000,000 invested.

How this is calculated

Income divided by sustainable yield: the capital that throws off the target passively.

What drives the result

Debt freedom is amortisation solved for time. Passive income is the goal divided by sustainable yield. Independence is spending divided by the safe withdrawal rate. All three improve twice when spending falls: less needed, more saved.

Recommendations

  • •Yield is not return — chasing it into junk destroys corpus.
  • •Reinvest until the corpus covers 120% of needs; buffers survive cuts.

Educational Content

Introduction

Freedom has three prices: zero debt, income that arrives without labour, and a portfolio that outlives you. These calculators price each — the debt-free date, the passive corpus, and the FIRE number — so independence becomes a dated plan.

Concept Explanation

Debt freedom is amortisation solved for time. Passive income is the goal divided by sustainable yield. Independence is spending divided by the safe withdrawal rate. All three improve twice when spending falls: less needed, more saved.

Applications

▸Dating debt freedom at current payments
▸Sizing the corpus for target passive income
▸Tracking progress to the FIRE number
▸Testing withdrawal-rate sensitivity

Benefits

  • •Debt-free date with interest cost
  • •Corpus sized to yield honestly
  • •FI progress as a percentage
  • •Withdrawal-rate trade-offs explicit

Limitations

  • •Yields and withdrawals aren’t guaranteed
  • •Taxes on passive income ignored
  • •Healthcare and housing shocks excluded
  • •Sequence-of-returns risk unmodelled

Best Practices

  • •Kill >7% debt before taxable investing
  • •Demand yield plus growth, never yield alone
  • •Target 120% of needs before declaring FI
  • •Keep 6 months cash even after FI

Common Misconceptions

Myth: Passive income needs no capital
Truth: Every stream was bought with capital, time or risk.
Myth: 4% works for 60-year retirements
Truth: It was calibrated for 30 — longer needs lower or flexible draws.

Practical Tips

  • •Demand growth plus yield, never yield alone.
  • •Build 120% of needs for cut buffers.

Common Mistakes

Chasing double-digit yields
Yield without coverage is return OF capital.

Assumptions

This calculator makes the following assumptions to provide estimates:

Yield sustained: Cuts and inflation unmodelled.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Yields and withdrawals aren’t guaranteed
Limitation: Taxes on passive income ignored
Limitation: Healthcare and housing shocks excluded
Limitation: Sequence-of-returns risk unmodelled

Frequently Asked Questions

Answers to common questions about this calculator.

What yield is sustainable?
~4% blended long-run; higher yields usually spend principal in disguise.
Who uses the passive income goal calculator?
It is used by households turning income into dated goals and funded plans. It sits in the Freedom Goals group of the Financial Planning & Goals section of Atlascalcs.
How accurate is the passive income goal calculator?
Every figure follows directly from the inputs using standard mathematics for passive income calculations, so it is accurate to the quality of the values you enter. All calculations run at full precision and round only for display.
Should I invest or pay down debt first?
Compare after-tax returns: debts above ~7% usually beat expected market returns on a risk-adjusted basis. Below that, splitting is defensible.
How much of my income should I save?
20% all-in is the standard target (including employer retirement); 30%+ buys freedom decades early.
Does rounding change the results?
Every calculation runs at full precision and rounds only for display.
What return should I assume?
6%–7% nominal for equities long-run (~4%–5% real); use lower figures for short horizons and stress-test.
