GIC Calculator

The three numbers that matter

The advertised rate is the nominal return. What you actually experience is the after-tax return (GIC interest is fully taxable as income outside registered accounts) and the real return after inflation. This calculator shows all three because the gap between them is where disappointment lives — a 4.25% taxable GIC at a 40% marginal rate with 2.5% inflation yields about 0.05% of real growth.

Registered accounts change everything

The exact same GIC inside a TFSA, RRSP, or FHSA skips the tax line entirely. For fixed income — which gets zero preferential tax treatment, unlike dividends or capital gains — sheltering is worth more than rate shopping. Check the growth math on the TFSA calculator.

GIC vs high-interest savings

The trade is simple: GICs pay a premium for your illiquidity, HISAs pay less but stay accessible. If you might need the money — or believe rates are rising — the HISA option or a cashable GIC keeps your options open. If the money is earmarked for a date certain (a down payment in three years), a non-redeemable GIC matched to that date is the cleanest risk-free parking in Canada. Full comparison: GIC vs HISA.

Laddering removes the rate bet

Nobody knows where rates go. Splitting across 1–5 year terms and rolling each maturity into a new 5-year GIC means one-fifth of your money re-prices annually — you never lock everything at the bottom, never chase the top, and always have cash coming due. For amounts under the $100,000 CDIC limit per institution, this is as close to a solved problem as saving gets.
