What Is FIRE?

Financial independence means your portfolio can support your spending without depending entirely on employment income.

FIRE stands for Financial Independence, Retire Early. In practice, many people use it less as a promise to stop working forever and more as a way to gain flexibility, optional work, or earlier freedom.

Annual spending matters because your future portfolio needs to support what you actually spend. A common shortcut is the 4% rule, which is often expressed as needing about 25 times your annual spending.

This is a simplified planning estimate, not personalized financial advice. Markets, taxes, inflation, and your withdrawal pattern all matter.

Educational insights

Short takeaways to help you understand what the numbers mean in plain English.

Canadian context

FIRE planning in Canada often works best when you combine portfolio math with account structure and future benefits.

TFSA and RRSP both matter

Tax-free growth in a TFSA and tax deferral in an RRSP can both support a FIRE plan. Which one helps most depends on your tax rate now versus later.

CPP and OAS can reduce later self-funding needs

Many FIRE plans bridge the years before government benefits start, then rely less heavily on the portfolio later.

Withdrawals are tax-sensitive

Registered withdrawals, capital gains, and account sequencing affect net income. This calculator is intentionally not a full tax engine.

Use this with your broader plan

For a stronger plan, pair this estimate with account-level contribution strategy, government benefit timing, and retirement income planning.

FIRE calculator guide

Helpful context for common questions about financial independence, retire early planning, and the 4% rule in Canada.

What is FIRE?

FIRE stands for Financial Independence, Retire Early. The core idea is simple: build enough invested assets that work becomes optional because your portfolio can help cover your annual spending.

How do you calculate your FIRE number?

Your FIRE number starts with annual spending, adjusted for any reliable passive income you expect in retirement. A common shortcut is dividing net spending by your withdrawal rate, or multiplying annual spending by a withdrawal multiple such as 25x.

What is a good savings rate for FIRE?

There is no perfect number, but higher savings rates usually shorten the timeline because they increase contributions and often reflect lower spending. Even moderate increases can materially change your projection.

How much do I need to retire early?

It depends more on what you spend than on a headline target. Someone spending $50,000 per year needs a very different portfolio than someone spending $100,000 per year.

Does the 4% rule work in Canada?

The 4% rule is a rough planning guideline, not a guarantee. Canadian taxes, asset mix, sequence risk, inflation, and account structure all affect how safe a withdrawal plan may be.

Can TFSA and RRSP be used for FIRE?

Yes. Both can be part of a FIRE plan. TFSAs provide tax-free withdrawals, while RRSPs can reduce taxes during high-earning years and still be useful later with thoughtful withdrawal planning.
