What Is Coast FIRE? A Complete Guide for Canadians
Most retirement advice follows the same script: save as much as possible for as long as possible, then retire. Coast FIRE flips that script — and for many Canadians it is a far more realistic path to financial freedom than traditional early retirement.
So what is Coast FIRE? Coast FIRE is a retirement strategy where you invest enough money early that — even if you never contribute another dollar — your portfolio grows on its own to fully fund retirement by your target age. Once you hit your Coast FIRE number, you only need to earn enough to cover current living expenses. Compounding does the rest. For Canadians, RRSP and TFSA sheltering plus CPP and OAS make the number materially smaller than the US versions of this idea suggest.
| Coast FIRE in Canada | The essentials |
|---|---|
| What it means | Enough invested today that growth alone funds retirement |
| What you keep doing | Working — but only to cover current expenses, not to save |
| Step 1: retirement number | Annual spending ÷ safe withdrawal rate (usually 4%) |
| Step 2: Coast FIRE number | Retirement number ÷ (1 + real return)years to retirement |
| Canadian levers | TFSA and RRSP tax sheltering; CPP and OAS reduce what your portfolio must cover |
| Average CPP + OAS at 65 (2026) | About $1,629/month, or $19,548/year |
| Typical age reached | 30s to early 40s with disciplined early investing |
| Nearest cousins | Traditional FIRE (retire fully), Barista FIRE (part-time now) |

How Coast FIRE works
Ask what is Coast FIRE in practice and the answer is a single mechanism: compound growth. When you invest in a diversified portfolio, the growth itself generates more growth, and the longer money is left untouched the more powerful that effect becomes. A dollar invested at 30 does far more work than a dollar invested at 50, because it has twenty more years to compound.
Coast FIRE takes advantage of this by front-loading your investing. Instead of saving steadily across a whole career, you save aggressively early to hit a target number. Once you reach it, you can “coast”: scale back contributions, take a lower-stress job, go part-time, or simply stop thinking about retirement savings at all.
The key insight is that time in the market is doing the heavy lifting, not your ongoing contributions. That is why a 30-year-old’s Coast FIRE number can be a small fraction of the amount they will eventually need at 65 — the gap is filled by three decades of growth.
Coast FIRE vs traditional FIRE vs Barista FIRE
Coast FIRE is part of the broader FIRE movement (Financial Independence, Retire Early), but it has a more accessible goal than the version most people have heard of. It also gets confused with Barista FIRE, which is a different strategy:
| Strategy | Goal | What happens after | Typical timeline |
|---|---|---|---|
| Traditional FIRE | Accumulate ~25× annual expenses and retire completely | Stop working; live off portfolio withdrawals | 10–20 years of extreme saving |
| Coast FIRE | Invest enough that compound growth funds retirement on its own | Keep working to cover current expenses only; no more saving required; portfolio untouched | Often reachable in your 30s |
| Barista FIRE | Portfolio covers part of expenses now; part-time work covers the rest | Semi-retire immediately and start drawing on the portfolio | Between the two |
The distinction that matters: in Coast FIRE your portfolio is untouched until retirement, so a bad market year during the coasting period costs you nothing. Barista FIRE is already drawing down, which is why it carries sequence-of-returns risk that pure Coast FIRE structurally does not. Our Barista FIRE calculator works through that trade-off, and the 4% rule underpins the “25×” figure in the first row.
Coast FIRE does not mean you stop working — it means you stop needing to save. Many people who reach it stay in their careers but negotiate better hours, move to more meaningful but lower-paid work, or simply feel a profound shift in how they relate to their job.
How to calculate your Coast FIRE number
Your Coast FIRE number is the amount you need invested today so that it grows to cover your full retirement needs by your target age, with no further contributions. The calculation has two steps.
Step 1 — your retirement number. Divide your expected annual retirement spending (in today’s dollars, after subtracting CPP, OAS and any pension) by your safe withdrawal rate. At the common 4% rate:
Step 2 — your Coast FIRE number. Discount that retirement number back to today using your expected real rate of return (investment return minus inflation) over the years until retirement:
The earlier you are, the smaller the number, because more years of compounding sit between you and retirement. Rather than work the exponent by hand, the Coast FIRE calculator handles both steps instantly, defaults to Canadian accounts and CPP/OAS, and includes a couple mode. For the arithmetic spelled out line by line, see how to calculate your Coast FIRE number; for help reading the results screen, see the Coast FIRE retirement calculator guide.

How Canadian accounts and benefits change the number
Canadians pursuing Coast FIRE have two structural advantages that most generic (US-written) guides ignore, and they pull in opposite directions from the two steps above.
Registered accounts speed up Step 2. Inside a TFSA, growth and withdrawals are completely tax-free, so your portfolio compounds for decades with no tax drag — every dollar of growth stays yours, which is exactly what a strategy built on compounding needs. Inside an RRSP, contributions are deductible now and growth is tax-deferred until withdrawal; the refund can itself be invested. First-time buyers also have the FHSA, which combines both treatments. When you count your current invested assets, add up all of them: TFSA, RRSP, FHSA and non-registered together.
Government benefits shrink Step 1. CPP and OAS are indexed and paid for life, so once they start your portfolio does not have to cover your whole spending. As of 2026 the average CPP retirement pension at 65 is about $877 a month and the maximum OAS for ages 65–74 about $752 — roughly $19,548 a year combined. Someone planning to spend $55,000 only needs the portfolio to produce about $35,500, which cuts the retirement number by close to half a million dollars. Ignoring this is the single biggest reason Canadians overestimate their Coast FIRE number.
If you plan to retire before 65, add a bridge. OAS cannot start before 65 and CPP cannot start before 60, so the subtraction above only holds from the day your benefits begin. In the years between your retirement date and that day, your portfolio pays your full spending. Add the value of those missing payments to your retirement number: with $60,000 of spending, $19,548 of CPP and OAS from 65 and a 4.5% real return, retiring at 60 adds about $89,700 and retiring at 55 about $161,600, taking the retirement number from $1,011,300 to roughly $1,172,900 — 16% more. Our Coast FIRE Calculator does this for you once you set the age your benefits start.
Which account to prioritise is a separate question. The usual rule is TFSA first in a lower bracket, RRSP first in a higher bracket you expect to leave in retirement, and both once income allows — our TFSA or RRSP guide covers the decision.
A real Canadian example
Sarah, 32, British Columbia. She plans to retire at 65 and expects to spend $55,000 a year in today’s dollars. She has $60,000 invested across her TFSA and RRSP, assumes a 7% return and 2.5% inflation (a 4.5% real return), and uses the current average CPP plus maximum OAS of about $19,548 a year.
| Step | Calculation | Result |
|---|---|---|
| Portfolio must cover | $55,000 − $19,548 | $35,452 / year |
| Retirement number | $35,452 ÷ 0.04 | $886,300 |
| Coast FIRE number today | $886,300 ÷ 1.04533 | ~$207,000 |
| Gap from where she is | $207,000 − $60,000 | $147,000 |
Investing about $1,000 a month at that real return, Sarah closes the gap in roughly nine years — at 41. From then on she never has to save for retirement again; her $207,000 grows to the $886,300 she needs by 65 on its own, and she only has to earn what she spends. Change one input — a 60 retirement, a $45,000 lifestyle, a workplace pension — and the number moves a lot, which is why running your own figures matters more than any rule of thumb.
Five mistakes that inflate your Coast FIRE number
- Using a nominal return instead of a real one. Discounting at 7% instead of 4.5% understates the number badly, and using 12% because the market did that recently is worse — see real vs nominal returns and what return rate to use.
- Leaving CPP and OAS at zero. Most calculators are built for Americans and ignore them; in Canada they can remove a third of the spending your portfolio must fund.
- Forgetting a defined-benefit pension. A teacher’s or nurse’s pension changes the arithmetic completely — the target becomes (spending − pension) × 25, not spending × 25. Our guide to Coast FIRE with a pension shows the gap method.
- Calculating for one person when you are a household. Two incomes, two sets of registered room and two CPP entitlements need a joint number — the Coast FIRE calculator for couples handles it.
- Counting the house. Home equity is net worth, not a retirement-funding asset unless you plan to sell — see does home equity count toward FIRE.
What happens after you reach Coast FIRE?
Reaching your number does not mean retiring tomorrow — it means you have bought yourself options. Common paths people take:
- Staying in the same job but feeling dramatically less stressed about money
- Moving to part-time or contract work
- Switching to lower-paying but more meaningful work
- Taking extended time off or a sabbatical
- Continuing to save anyway, and arriving at retirement with more than needed
The defining characteristic of Coast FIRE is not what you do after — it is the psychological shift. When you know retirement is already funded, every career decision becomes a choice rather than a necessity. The wider FIRE movement that Coast FIRE grew out of is summarised well by Investopedia’s FIRE overview; Coast FIRE is the version that keeps the flexibility without demanding the extreme savings rate.

Frequently asked questions
Coast FIRE means you have invested enough that compound growth alone will fund your retirement by your target age, without any further contributions. You keep working, but only to pay for life now, not to save for later.
Two steps. First, divide the annual retirement spending your portfolio must cover (after CPP, OAS and any pension) by your safe withdrawal rate, usually 4%, to get your retirement number. Then divide that by (1 + real return) raised to the number of years until retirement. A 4.5% real return over 33 years divides the target by about 4.27.
It depends on your age, retirement age, spending and return assumption. For a 32-year-old retiring at 65 on $55,000 a year with average CPP and maximum OAS, the Coast FIRE number is roughly $207,000 at a 4.5% real return. A 45-year-old with the same plan would need about $370,000, because there is less time for growth.
Yes, and they matter a great deal. Subtract your expected CPP and OAS from your retirement spending before calculating your retirement number. In 2026 the average CPP at 65 is about $877 a month and the maximum OAS for ages 65 to 74 about $752, so together they can cover close to $20,000 a year of spending that your portfolio then does not have to fund. One exception: if you retire before your benefits start (OAS at 65, CPP from 60 at the earliest), your portfolio also has to cover the gap years, which adds to the retirement number; retiring at 55 instead of 65 raises it by about 16% in our example.
No. In Coast FIRE your portfolio stays untouched until retirement and work covers all current expenses. In Barista FIRE the portfolio already covers part of your expenses and part-time work covers the rest, so you are drawing down earlier and carry market-timing risk that Coast FIRE does not.
Of course. Coast FIRE is the point at which contributions become optional, not forbidden. Anything you keep adding either brings retirement forward, raises your retirement income, or builds a margin against lower-than-expected returns.
