FIRE (Financial Independence, Retire Early) starts with one number: the portfolio size that can fund your life forever. This calculator shows you that number, how long it takes, and when you can coast the rest of the way.
If you want to spend $60,000/year and use a 4% withdrawal rate, your FIRE number is $1,500,000. That portfolio, invested at historical returns, should sustain indefinite withdrawals. Canadians with CPP and OAS need less — those income streams reduce what the portfolio must cover.
Coast FIRE is the portfolio value at which, if you stopped contributing today, compound growth alone would carry you to your full FIRE number by retirement age. Once you hit it, new contributions become optional — you just need to cover expenses without drawing down investments.
In Canada, RRSP and RRIF withdrawals are fully taxable income. This tool grosses up your spending target to account for the tax owing on withdrawals, then derives a larger FIRE number accordingly. TFSA withdrawals are tax-free and don't affect OAS clawback or GIS eligibility.
A major market crash in your first few retirement years — combined with ongoing withdrawals — can permanently damage a portfolio even if long-run returns are fine. This is sequence-of-returns risk. It's why many Canadian FIRE planners use a 3–3.5% withdrawal rate for retirements exceeding 30 years, and keep a cash buffer of 1–2 years of expenses in a HISA.
