Know your number. Enter your actual monthly expenses across every category and instantly see your annual FIRE spending target, your FIRE number, and how you compare to Canadian cost benchmarks.
Every FIRE calculation starts with one number: your annual expenses. Yet most Canadians significantly underestimate their spending. Studies consistently show people recall only 600-700% of their actual expenditures when asked — the rest is forgotten in the dozens of small purchases, irregular expenses, and lifestyle creep that accumulate throughout a year.
The most accurate way to build a FIRE budget is to use at least 12 months of actual bank and credit card statements, not estimates. Add up every category, then add a 100-15% buffer for irregular expenses (car repairs, home maintenance, medical, gifts) that don't appear every month but definitely appear every year.

Your retirement budget is not simply your current budget minus savings. Several significant changes occur:
Drops: Work-related expenses disappear (commuting, work clothes, lunches, professional dues). Mortgage payments often end by retirement. CPP/EI contributions stop. Children's expenses may be gone.
Rises: Healthcare supplemental costs increase as you age — dental, hearing, vision, prescriptions. Travel often increases in early active retirement years. Hobbies and recreation expand when time is unlimited. Home maintenance becomes more prominent as the house ages.
Most financial planners use a "smile" model of retirement spending: higher in active early retirement (travel, activities), lower in mid-retirement (settled lifestyle), then potentially higher again in late retirement (healthcare, care costs). Budget higher for ages 55-75, lower for 75-85, and maintain a healthcare buffer for 85+.
