Frequently Asked Questions

Canada's CPI peaked at 8.1% in June 2022 — the highest since 1983. Causes: pandemic supply-chain disruptions, Russia-Ukraine war (energy/food), and aggressive monetary stimulus. The Bank of Canada raised rates from 0.25% to 5.0% between March 2022 and July 2023. By early 2025, inflation had returned near the 2% target and the policy rate had been cut to approximately 3.25%.
$70,000/year in expenses today becomes $127,000 in 30 years at 2% inflation. Your portfolio must outpace inflation or you lose real purchasing power. Equities have historically outpaced inflation by ~4–5% real return. Cash and low-yield fixed income often fail to keep up — which is why holding too much cash in early retirement is risky.
Nominal return is the stated return (e.g., 7%). Real return adjusts for inflation: Real ≈ Nominal − Inflation. At 7% nominal with 3% inflation, real return is ~4%. The Fisher equation is more precise: Real = (1 + Nominal) / (1 + Inflation) − 1. Always compare investment returns in real terms to know if you're actually getting ahead.
