📊 Withdrawal Rate Guide

Safe Withdrawal Rates for Canadians

What percentage of your portfolio can you safely withdraw each year without running out of money? The answer depends on your retirement length, flexibility, and government benefits.

What is a withdrawal rate?

Your withdrawal rate is the percentage of your portfolio you spend in the first year of retirement, adjusted for inflation each year after. It's the key variable that determines how large a portfolio you need to retire.

Withdrawal rate and FI Number are directly linked:

FI Number = Annual Expenses ÷ Withdrawal Rate

At 4%: need 25× annual expenses
At 3.5%: need 28.6× annual expenses
At 3%: need 33.3× annual expenses

Dropping from 4% to 3% increases the required portfolio by 33%.

Which rate for which retirement horizon?

These are general guidelines. Historical success rates are based on globally diversified portfolios and do not include CPP/OAS income offsets — which would push actual success rates higher for Canadians.

Why Canadians can often use slightly higher rates

CPP and OAS are inflation-indexed, lifelong income streams that act as a floor under your retirement income. They reduce how much of your portfolio you actually need to draw each year — especially in the later phases of retirement when they're fully active.

Effective withdrawal rate vs nominal rate:

If you spend $70,000/year and receive $20,000 from CPP+OAS, you only withdraw $50,000 from your portfolio.

On a $1,250,000 portfolio, that's an effective withdrawal rate of 4.0% — but your nominal rate (spending/portfolio) is 5.6%. The government benefits are doing meaningful work.

Fixed vs flexible withdrawal strategies

📌

Fixed withdrawal

Withdraw a set dollar amount each year (inflation-adjusted). Simple, predictable, but doesn't respond to market conditions. Higher failure risk in bad sequences.

📈

Percentage of portfolio

Withdraw a fixed % of current portfolio value each year. Never fully depletes the portfolio, but income fluctuates. Works well with flexibility.

🛡️

Guardrails method

Set an upper and lower spending limit. If portfolio drops 20%, cut spending 10%. If portfolio rises 20%, increase spending 10%. Very robust.

🏦

Bucket strategy

Keep 1–2 years expenses in cash, 3–7 years in bonds, rest in equities. Never sell stocks in a downturn — replenish from bonds and cash instead.

Research consistently shows that flexible withdrawal strategies survive longer and with larger final portfolios than fixed withdrawal rates — at the cost of income uncertainty.

Why the first 10 years matter most

The biggest threat to a retirement plan isn't average returns — it's the sequence of returns. Getting bad returns early in retirement, while withdrawing, permanently impairs the portfolio in a way that later good returns can't fully fix.

Example: Two retirees start with $1M and average 7% returns over 30 years. Retiree A gets good early returns, bad late. Retiree B gets bad early returns, good late. Same average. Retiree A ends with $2.5M. Retiree B runs out of money at year 22 — despite identical average returns.

This is why FireCA's Monte Carlo simulation and historical crash testing matter — they model this risk explicitly, not just average outcomes.
