FIRE Calculator (Canada)
This free Canadian FIRE calculator finds your FIRE number — the portfolio you need to retire early — from your annual spending and a safe withdrawal rate, then factors in CPP and OAS to show the age you can realistically stop working. Model Coast, Lean and Fat FIRE for your own numbers.

How your FIRE number is calculated
The classic rule uses a 4% safe withdrawal rate: your FIRE number is annual spending × 25. Spending $50,000/year implies roughly $1.25M — but Canadian CPP and OAS reduce what your portfolio must cover, often substantially. Retirely folds those benefits in so your target is realistic, not inflated.
Coast, Lean and Fat FIRE
- Coast FIRE: you have enough invested that growth alone reaches your number by retirement, without new contributions.
- Lean FIRE: a smaller number supporting modest spending.
- Fat FIRE: a larger number supporting a comfortable, higher-spending retirement.
Frequently asked questions
What is my FIRE number?
Your FIRE number is the invested amount that lets you live off withdrawals indefinitely — typically annual spending divided by your safe withdrawal rate (4% → ×25). In Canada, CPP and OAS lower the amount your own portfolio must provide.
Does CPP and OAS change my FIRE number?
Yes, significantly. Because CPP and OAS provide guaranteed, inflation-indexed income from your 60s, your portfolio only has to cover the gap. Retirely subtracts expected benefits so your FIRE target reflects Canadian reality.
