Financial independence calculator
Know your FI number and the path to reach it
Set the income you want in retirement and a withdrawal rate to find your target. Your FI-eligible wealth and contributions then give an estimated date for reaching it.

The target
Income ÷ withdrawal rate = FI target
£42,000 a year at a 4% withdrawal rate needs £1,050,000. The withdrawal rate is an assumption you choose, not advice, and small changes move the target a long way.
The date
From today's position to an estimated date
Your FI-eligible wealth grows with contributions and your planning return, month by month, until it reaches the target. The first month it does is your estimated FI date.
- Uses FI-eligible wealth, not total net worth.
- Contributions can change over time in dated phases (Plus and Pro).
- Values are shown in future (nominal) money.

Assumptions
Every input stays in view
The result is only as useful as its assumptions, so each one is shown beside it and can be changed. Adjust one and the target and date recalculate.
- Retirement spending
- A set amount, or based on your recorded expenses
- £42,000/yr
- Withdrawal rate
- Typically between 3% and 5%
- 4%
- Contributions
- One amount on Free; dated phases on Plus
- £2,800/mo
- Planning return
- Derived from your holdings, or set by you
- 6.2%
- Inflation
- Applied to income entered in today's money
- 2.5%
- Retirement timing
- When you reach the target, or a date you choose
- At target
Estimates, not promises
Methodology- Returns vary
- The date assumes a steady planning return. Real markets won't deliver one. Monte Carlo on Plus shows the range.
- Before tax
- Tax isn't calculated, so targets and dates are shown before tax.
- Planning, not advice
- The result is information to plan with, not a recommendation.
Questions
The FI calculator, answered
Is the estimated FI date a prediction?
No. It's the first month your FI-eligible wealth reaches the target if your contributions, planning return and inflation turn out exactly as entered. Change any assumption and the date moves; real returns won't be steady, which is why the range of outcomes is shown separately on Plus and Pro.
Which withdrawal rate should I use?
That's your decision. Yield Clarity doesn't recommend one. A lower rate means a larger target and a later date. Try several and compare the results before settling on an assumption.
Does the calculator include pensions and tax?
Pension pot balances count toward FI-eligible wealth. Defined benefit and state pension income are recorded separately and don't reduce the target. Tax is not calculated, so results are before tax.
Why doesn't it use my whole net worth?
Some of what you own (a home, a car, money set aside) won't fund your retirement. The calculation uses FI-eligible wealth: the assets you've chosen to live on.
Which assets count toward FIFind your FI number
Enter your retirement income and withdrawal rate, add your FI-eligible assets, and see an estimated date.
