A GIC pays interest in one of two broad ways: out to you on a schedule (monthly, semi-annually, or annually), or left inside the certificate to compound until maturity. That choice changes when you see the money and, more than most savers expect, how much of it there is at the end.
If GICs themselves are new territory, start with what a GIC is; everything here assumes that groundwork. (The examples also assume a plain fixed-rate GIC; the other GIC varieties set interest differently.) The first fork is where the interest goes.
Two ways to get paid, and why the monthly version quotes lower
Every GIC earns interest steadily through the term. The payout option decides what happens to that interest once it’s credited.
With a payout GIC (often sold as an “income” option), interest is deposited to your linked savings or chequing account on a schedule. The principal stays locked in; the interest walks out the door as it’s earned. With a compound GIC, the interest stays inside the certificate, gets added to the principal, and starts earning interest itself. You collect everything in a single payment at maturity.
| Payout option | When interest lands | How the rate usually compares |
|---|---|---|
| Monthly pay | Your linked account, every month | Lowest quote for a given term |
| Semi-annual pay | Your linked account, twice a year | Slightly below annual pay |
| Annual pay | Once a year, on the anniversary date | The headline rate for the term |
| Compound to maturity | One payment when the term ends | Quoted like annual pay (interest also earns interest) |
Not every institution offers every option on every term. Short terms (under a year) usually just pay at maturity, since there isn’t much of a year to schedule payments across.
About that lowest-quote line in the table: it can look like a penalty, but it’s really just pricing. When interest is paid out monthly, two things happen: you get use of the money sooner, and the institution loses use of it sooner. Money in your hands today is worth more than the same money a year from now, so the institution offsets that by quoting the monthly-pay version of a GIC a fraction of a percentage point below the annual-pay version of the identical term.
There’s a second, quieter effect: interest that leaves the certificate every month never gets the chance to earn interest of its own. So a monthly-pay GIC gives up ground twice, once in the quoted rate and once in the lost compounding. That’s a fair trade if you actually need the monthly income (retirees living off deposit interest, for instance). It’s a poor trade if the payments just land in a chequing account and sit there.
The table below prices the payout menu as it stands on our boards: monthly pay against annual pay against compounded to maturity.
What compounding adds
None of the numbers below come from a board; they’re round on purpose, to keep the mechanics visible. Suppose you put $10,000 into a 5-year GIC at 4%.
With annual payout, you receive $400 each year. Over five years that’s $2,000 of interest, and you end where you started: $10,000 of principal plus $2,000 collected along the way.
With annual compounding, each year’s interest joins the principal before the next year’s interest is calculated. The same $10,000 grows to roughly $12,167 at maturity. That extra $167 is the interest your interest earned. It sounds modest, and in year one it is (nothing at all), but the effect snowballs with time and with larger deposits: the same arithmetic on $100,000 is an extra $1,670 or so. CIRO’s investor office has a plain explainer on compound interest if the mechanics are new to you.
Compounding frequency matters too, a little. A rate compounded monthly instead of annually squeezes out slightly more: 4% compounded monthly works out to an effective annual yield of about 4.07%. This is the difference between the quoted (nominal) rate and the effective yield. The quoted rate is the input; the effective yield is what your balance actually does over a year once compounding is counted. When two offers quote the same rate with different compounding, the more frequent compounding wins by a hair. When they quote different rates, the rate difference almost always matters more than the compounding difference. The longer story of what that snowball does over full terms is in our piece on compound interest and real rates.
What “annual pay” means inside a registered account
Inside a TFSA or RRSP, “paid out” doesn’t mean paid to you. Interest credited by a registered GIC lands in the cash balance of the plan, not in your chequing account, because moving it outside the plan would be a withdrawal, with all the room and tax consequences withdrawals carry.
In practice this makes the payout question less dramatic inside registered accounts. Whether interest is credited annually to the plan’s cash or compounded inside the certificate, it stays sheltered either way. The main difference is housekeeping: annually credited interest sits in plan cash (often earning very little) until you reinvest it, while a compounding GIC reinvests it for you automatically. For money you’re leaving alone anyway, compounding is the tidier default.
Pick the payout for the job, then compare like with like
The payout option is a cash-flow decision, not a returns hack: choose income payments if you’ll spend the interest, and compounding if you won’t. The returns decision is the rate itself, and there the one trap is comparing a monthly-pay quote at one institution against an annual-pay quote at another. Always compare the same payout option across institutions.
When you’re ready to compare, the current GIC boards show what each term pays right now, and a rate alert will tell you when the number you’re waiting for shows up.
Frequently asked questions
Is a monthly-pay GIC worth the lower rate?
Only if you’ll actually use the monthly income. If the payments would just accumulate in a chequing account, you’re accepting a lower rate and giving up compounding for no benefit. If the interest is part of your monthly budget, the convenience can be worth the modest rate haircut.
Do compound GICs pay a higher rate than annual-pay GICs?
Usually the quoted rate is the same, but the compound version ends up worth more at maturity because each year’s interest earns interest in the following years. The gap grows with the length of the term. On a 1-year GIC there’s no difference at all, since there’s only one interest payment either way.
How is compound GIC interest taxed before maturity?
In a non-registered account, interest on a compound GIC is taxable each year as it accrues, even though you don’t receive it until maturity, so a 5-year compound GIC generates tax slips along the way; how interest income is taxed walks through those slips. Inside a TFSA, RRSP, or FHSA, the interest is sheltered and this issue disappears.
What is the difference between the quoted rate and the effective yield?
The quoted rate is the nominal annual rate the institution advertises. The effective yield is what your balance actually grows by over a year once compounding frequency is factored in. With annual compounding the two match; with monthly compounding the effective yield runs slightly above the quoted rate.
