Estimate the portfolio size, savings rate, and retirement-age tradeoffs behind a Canadian Financial Independence, Retire Early plan. This calculator includes CPP, OAS, inflation, and part-time income assumptions, but it does not promise that a retirement plan is safe.
Your FIRE number
$1.25M
4% withdrawal rate x $50,000/yr
Portfolio at retirement
$1.05M
16% below target
Portfolio lasts until
Age 95+
Modeled through age 95
Savings rate

Calculation details
Red dashed line = your FIRE number. Chart values are modeled in real, inflation-adjusted terms.
Result insight
This scenario is most useful when it shows which assumption is doing the most work. If the target only works with a high return, high withdrawal rate, or optimistic CPP/OAS estimate, the plan needs a second pass before the retirement age becomes meaningful.
Original FIRE checks
The years before CPP and OAS can carry more withdrawal pressure.
Works better when: TFSA, taxable savings, or part-time income cover the early years cleanly.
Watch out when: RRSP withdrawals create taxable income earlier than expected.
Rent, mortgage renewal, repairs, and moving costs can matter more than the portfolio return.
Works better when: core expenses are modeled with a realistic margin.
Watch out when: the annual expense input excludes irregular housing costs.
A 0.5% change in withdrawal rate can move the target by years.
Works better when: you compare 3.25%, 3.5%, and 4% instead of one tidy number.
Watch out when: a long retirement is modeled with a short-retirement rule of thumb.
Withdrawals, benefits, and part-time income can stack into the same tax year.
Works better when: RRSP, TFSA, taxable, CPP, and OAS income are planned together.
Watch out when: pre-tax and after-tax dollars are mixed in one simple projection.

What this calculator does
The calculator estimates a FIRE number from annual expenses and withdrawal rate, then projects how current savings and annual savings may grow before retirement. It also models portfolio withdrawals, CPP, OAS, and optional part-time income during drawdown.
How to use it
Enter current age, target retirement age, current investments, annual income, annual expenses, return, inflation, withdrawal rate, and government-benefit estimates. Then test Lean, Regular, Fat, and Barista FIRE scenarios to see which assumptions drive the result.
Real Canadian scenario
A Canadian household wants to leave full-time work before age 55, but most public retirement benefits are modeled from age 65. The key question is whether the portfolio can survive the bridge years without assuming every market year is average.
The selected scenario does not reach the modeled target by the chosen age.
The useful part is not the pass/fail label. It is the gap between the FIRE number and the projected portfolio, plus whether the chart runs out before age 95 under the selected assumptions.
Limitation: This does not model exact account withdrawal order, tax brackets, health spending, insurance needs, future CPP/OAS rules, or sequence-of-returns volatility.
Inputs explained
The spending target used to estimate the portfolio required for retirement.
The percent of portfolio modeled as annual retirement income.
Used together to estimate real, inflation-adjusted growth.
Modeled as income that can reduce portfolio withdrawals after certain ages.
Example calculation
With annual expenses of $50,000, a 4% withdrawal rate, and the selected FIRE style, the estimated FIRE number is $1.25M. The model projects $1.05M by age 50 under the current savings and return assumptions.
How to read your result
FIRE planning is sensitive to expenses, inflation, returns, taxes, fees, and withdrawal rate. Compare this result with the compound interest calculator, RRSP calculator, and CPP/OAS estimator before drawing conclusions.
Common mistakes
Last updated: April 2, 2026
The calculator estimates a FIRE number from expenses and withdrawal rate, projects accumulation with real returns, then models drawdown to age 95 with CPP, OAS, and optional part-time income offsets.
