FIRE Calculator Canada

Financial Independence, Retire Early (FIRE) comes down to one number: the portfolio size at which your investments, rather than your job, cover your cost of living. This calculator finds that number and estimates how many years of saving it will take.

What your FIRE number represents

If your portfolio is large enough that a safe yearly withdrawal covers your spending, you no longer depend on employment income. The usual rule of thumb is the 4% rule, which gives a FIRE number of 25 times annual expenses: spend $40,000 a year and your number is $1,000,000. The calculator uses whatever withdrawal rate you choose.

The 4 per cent rule and the multiple

The 4% rule comes from research into how much a retiree could withdraw each year without running out over a long retirement: take 4% in the first year, adjust for inflation afterwards, and history suggests the portfolio has a strong chance of lasting decades. Because 4% is one twenty-fifth, it produces the 25x multiple:

• 4% gives 25 times expenses.
• 3.5%, more conservative, gives about 28.6 times expenses.
• 5%, more aggressive, gives 20 times expenses.

How the years to independence are projected

The calculator projects your savings one year at a time: it grows the balance by your expected return, adds that year’s saving, and checks whether the total has reached your FIRE number. Current savings, annual saving and expected return drive the timeline, and small changes to any of them, especially how much you save, can move your date by years.

A worked example

• Annual expenses of $40,000
• Current savings of $50,000
• Annual saving of $20,000
• Expected return of 5%
• Withdrawal rate of 4%

The FIRE number is $40,000 / 4% = $1,000,000. Starting from $50,000, which is 5% of the target, and adding $20,000 a year at 5%, the balance reaches $1,000,000 in about 24 years, with $480,000 of new contributions along the way.

At a 3.5% withdrawal rate, the same $40,000 of spending needs about $1,142,857, over $140,000 more, which shows that the withdrawal rate matters as much as the savings rate. At 5% the target drops to $800,000, with a higher risk of running short.

The biggest lever: your savings rate

A high savings rate works twice: the portfolio grows faster, and because you live on less, the FIRE number itself is lower. Someone who lives on $30,000 needs far less than someone who spends $60,000, and can save more along the way. Cutting expenses frees cash to invest and moves the finish line closer.

How CPP and OAS fit in

The classic FIRE calculation ignores government pensions to stay conservative. Canadian retirees can also count on the Canada Pension Plan and Old Age Security later in life, which reduce what your own savings must cover from your sixties. A strict FIRE number may therefore overstate what you need. The retirement income gap calculator on this site shows how those pensions change the target.

How your province shapes the number

Your FIRE number starts from your expenses, and housing, the largest cost for most households, varies widely: a number that supports a comfortable life in Halifax or Winnipeg may fall short in Vancouver or Toronto. Province also affects tax in retirement. RRSP and RRIF withdrawals are taxed as income at your combined federal and provincial rate, while TFSA withdrawals are tax-free everywhere and do not count toward income-tested benefits. Because this calculation is in before-tax dollars, someone in a high-tax or high-cost province should aim toward the upper end of their target range.

Common mistakes and planning tips

Focusing on the portfolio value while ignoring the spending it must support is the biggest mistake. Treating the 4% rule as a guarantee rather than a historical guideline is another. Ignoring CPP and OAS entirely can overstate the requirement. Prioritize your savings rate, fill TFSA and RRSP room deliberately, and rerun the projection each year as your balance and expenses change.

Limitations

The projection uses today’s before-tax dollars, one expected return and a fixed withdrawal rate. It does not model inflation year by year, the order of returns, account taxation, or CPP and OAS. Use it to set direction and to test how savings, return and withdrawal rate interact, then refine the plan for inflation and tax or with a qualified adviser.
