Withdrawals
4% Rule Calculator
Translate annual spending into a target portfolio using the classic 4% rule framework.
Projection outlook
Follow the portfolio path over the withdrawal horizon to see whether the balance continues to support the plan.
The model ends near $1,000,000 after 2 years, which helps show how durable the withdrawal path looks under the current assumptions.
Scenario comparison
Use the spread between scenarios to see how sensitive this outcome is to the assumptions you change first.
Conservative currently leads optimistic by about $250,980, which shows the approximate range across the modeled cases.

How to use this output
Start with the main result at the top. Then review the key numbers, look at how the chart changes over time, and compare the Base, Optimistic, and Conservative scenarios before making a decision.
Saved scenarios
Save multiple scenarios to compare optimistic, conservative, and custom planning paths later.
What this tool does
- Models your current plan in plain English.
- Highlights the most decision-useful outputs instead of overwhelming you with raw math.
- Shows base, optimistic, and conservative views to make tradeoffs clearer.
Example scenario
The 4% rule is a useful first-pass estimate for converting spending into a portfolio target, especially when paired with scenario ranges.
Key assumptions
- Returns are smoothed estimates and do not reflect real-world market volatility.
- All figures are in today's dollars unless the calculator is explicitly modeling inflation adjustments.
- This tool is intended for planning, education, and comparison rather than certainty.

- 1.WealthyNest uses reusable finance formulas for compounding, withdrawal targets, and cash-flow projections.
- 2.Each tool pairs those formulas with calculator-specific assumptions and a concise summary.
Common mistakes
- Using unrealistic return assumptions.
- Ignoring taxes or healthcare when setting a spending target.
- Treating the output as fixed instead of revisiting it regularly.

FAQ
Are these outputs guarantees?
No. They are planning estimates based on your assumptions and should be updated as markets, taxes, and spending change.
Do these calculators replace professional advice?
No. They are a strong planning starting point, but tax, legal, and investment decisions should be reviewed with a qualified professional when appropriate.
How often should I revisit my inputs?
A good rule is to revisit assumptions after major income, spending, family, tax, or market changes and at least a few times per year.
Why do the optimistic and conservative scenarios matter?
They help you see how sensitive the result is to assumptions instead of anchoring on one exact output.
Should I include inflation separately?
Yes when the calculator allows it. Separating inflation from returns usually makes the planning logic easier to understand.
What if my real life differs from the model?
That is normal. Use the output as a planning range and update the scenario as new information arrives.
Which metric should I pay attention to first?
Start with the headline summary and the first two or three result cards. Those usually hold the most decision-useful information.
Can I share these results with someone else?
Yes. Major calculators support shareable URL state so you can copy the scenario link and send it directly.
