WITHDRAWAL-RATE SENSITIVITY
See how the assumption changes the target
A lower rate mechanically creates a larger first-pass FI number. These rates are comparisons, not recommendations.
| Planning withdrawal rate | Spending multiple | FI number today | FI number in future money |

The rate is an assumption about how much of the starting portfolio is represented by first-year spending. Real-world sustainability depends on market returns, inflation, taxes, fees, spending flexibility and time horizon. Explore sequence risk with the 4% Rule Stress Test →

At a fixed rate, spending and the FI target move together

WHAT THE NUMBER MEANS
A transparent spending-based target
Your first-pass FI number is the annual spending the portfolio needs to fund divided by the planning withdrawal rate you select.
FI number todayAnnual portfolio-funded spending ÷ Planning withdrawal rate
If dependable pension, rental or other recurring income will cover part of your lifestyle, subtract that income from spending before using this quick reference.

FAQ
Questions about the FI number
What is a financial independence number?
It is a planning estimate of the invested portfolio that corresponds to the annual spending a portfolio needs to fund under a chosen withdrawal-rate assumption.
Is 25× annual spending always enough?
No. Twenty-five times annual spending is simply the reciprocal of a 4% starting withdrawal-rate assumption. Real-world sustainability depends on market returns, inflation, taxes, fees, spending flexibility and time horizon.
Why does a lower withdrawal rate create a larger FI number?
The formula divides annual portfolio-funded spending by the rate. A smaller denominator therefore creates a larger first-pass target.
Should I include income such as pension or rent?
Enter only the spending the portfolio needs to fund. If dependable income will cover part of your spending, subtract that amount first.
Should I use monthly or annual spending?
Use whichever is easier. Monthly inputs are multiplied by 12 internally, so equivalent monthly and annual amounts produce the same target.
Why is there a future-money FI number?
It helps separate a target in today's purchasing-power terms from the larger nominal number that could result if the same spending rises with inflation for several years.
Does this tool model investment returns?
No. It estimates the target implied by spending. Use the full FI Planner for current assets, recurring investments, returns and target age.
Does changing currency convert my spending?
No. Currency selection changes the unit and number format only. The numeric amount you enter is not converted using an exchange rate.
SOURCES & PREPARATION
Same FI convention, simpler question
This quick reference uses the same spending-based sustainable-FI convention documented in the Carrowmont Financial Independence Planner. It isolates the target question without recreating the full portfolio-growth engine.
