Financial Independence Calculator
Estimate how long it may take to reach financial independence based on your expenses, savings, investment returns and withdrawal rate.
Overview
A financial independence calculator helps you estimate the portfolio size you may need to support your spending and how far away you are from that goal. Enter your current portfolio, annual expenses, annual contributions, expected return and withdrawal rate to see a simple FI estimate.
How it works
The calculator estimates your financial independence target by dividing your annual expenses by your chosen withdrawal rate. For example, a 4% withdrawal rate means multiplying annual expenses by 25. It also compares that target with your current portfolio to show your remaining gap. The timeline shown is a simple estimate based on filling that gap with annual contributions, and it does not fully model the year-by-year compounding path, taxes or changing expenses.

- 5Review your FI target, remaining gap and estimated years to FI.
Example Calculation
Current portfolio value
$100,000
Annual living expenses
$40,000
Annual contribution
$25,000
Expected annual return
7%
Safe withdrawal rate
4%
Annual after-tax income
$80,000
FI target
$1,000,000
With annual expenses of $40,000 and a 4% withdrawal rate, the FI target is about $1,000,000. If the current portfolio is $100,000, the remaining gap is about $900,000. Contributing $25,000 per year gives a simple no-growth timeline of about 36 years, while real-world compounding could shorten that.
Frequently asked questions
What does this financial independence calculator estimate?
It estimates the portfolio value needed to support your annual expenses and shows how far away you are from that target.
How is the FI number calculated?
The FI number is calculated by dividing annual expenses by your chosen withdrawal rate. At a 4% withdrawal rate, that is roughly 25 times annual expenses.
Why does the timeline say it is a simple estimate?
The years-to-FI result shown here uses a basic gap-and-contribution approach and does not fully model year-by-year compounding, taxes, inflation or changing contributions.
What withdrawal rate should I use?
Many people start with 4% as a rough benchmark, but a suitable rate depends on spending flexibility, time horizon, market conditions and personal risk tolerance.
Should I use pre-tax or after-tax expenses?
It is usually more practical to use the annual spending you expect your portfolio to support, including the effect of taxes if relevant to your situation.
Does this calculator include inflation?
Not directly. You can adjust your expected return or expenses to reflect your own inflation assumptions.
