Background

Financial Independence Calculator

Financial Independence (FI): To no longer have to set an alarm for a job you don't enjoy, ask permission for time off, or stay somewhere just because you need the pay cheque. Your money already covers your life, so from here work is something you choose to do, not something you're forced to.

See how your savings could grow into full financial independence anywhere in the world accounting for the taxes and other income that actually apply to your plan.

Life expectancy + 5yr buffer

 

United Kingdom: Income tax from 20% to 45% after the personal allowance (~£12,570). ISA withdrawals are tax-free; pension withdrawals taxed as income. 20% approximates a blended effective rate on a moderate withdrawal. This rate takes into account existing rates of income tax in United Kingdom and gives an average . you’re welcome to change it above if your own situation is different.

Your plan below is projected to age 86 — average life expectancy in United Kingdom is 81, with a 5-year planning buffer added. You're welcome to change that above.

04  Other income in FI

Rental income, Defined Benefit/Final Salary Pension income, State Pension income, part-time or spousal income — anything that will cover part of your spending once you're financially independent.

05  Leaving a legacy

Enter in today's money — we'll inflate it at 2% p.a. to future value (£0 by age 86). Investable assets only, excludes property and doesn't factor in any Inheritance Tax (IHT) that may be due.
