How a GIC ladder works in Canada, with a five-rung example
Anyone who has held cash in Canada has faced the same irritating choice. A high-interest savings account (HISA) is flexible, but its rate can drop whenever the bank likes. A guaranteed investment certificate (GIC) locks in a rate, but you give up access for the term. Lock everything up for five years and you may regret it when rates rise or when you need the money. Keep everything in savings and you may regret it when rates fall.
A GIC ladder is the old, unglamorous compromise. Instead of one big decision, you make several small ones, staggered so that some of your money always matures soon. This guide builds a ladder step by step with real arithmetic, shows what it costs compared with the alternatives, and spells out when it is not worth the trouble.
The rates below are the benchmark rates used in the GIC & Cash Ladder Yield Optimizer, dated September 2026. They are illustrations, not offers — check current rates before you buy anything.
What a GIC actually is
A GIC is a deposit with a bank, credit union or trust company that pays a fixed rate if you leave the money in for a set term, commonly from 30 days to five years. Most are non-redeemable: you cannot get your money out early. Some are cashable or redeemable, but they typically pay a lower rate. Interest may be paid out periodically or compounded annually and paid at maturity; the examples here use annual compounding, matching the calculator.
Eligible deposits at CDIC member institutions are insured up to $100,000 per depositor, per insured category, per institution. Registered accounts such as a TFSA or RRSP count as separate categories, which matters when a ladder gets large.
The ladder: five rungs, $30,000
Suppose you have $30,000 you will not need for several years. Instead of one GIC, you split it into five equal rungs of $6,000, one each for terms of one to five years, at these benchmark rates:
| Rung | Rate | Value at maturity |
|---|---|---|
| 1-year | 3.40% | $6,204.00 |
| 2-year | 3.65% | $6,445.99 |
| 3-year | 3.80% | $6,710.32 |
| 4-year | 3.90% | $6,992.19 |
| 5-year | 4.00% | $7,299.92 |
In the first year the five rungs together earn about $1,125, a blended rate of 3.75%. A savings account paying a steady 2.75% would earn $825 on the same $30,000. That is $300 more, in exchange for locking up most of the money.
The key step: what happens when a rung matures
At the end of year one the 1-year GIC matures, turning $6,000 into $6,204. This is the whole point of a ladder: you now have a decision, and some cash, every year. You have three sensible options:
- Reinvest at the long end. Buy a new 5-year GIC with the $6,204. After a few years, every rung is a 5-year GIC maturing a year apart — the classic steady-state ladder, which earns the higher long-term rate but still frees up cash every year.
- Spend it. If you need money, a rung has just matured and you pay no penalty.
- Park it in savings. If rates look unusually good or you want flexibility for a quarter or two, move it to a HISA.
If that first rung is rolled into a 5-year GIC at 4.00%, it grows to about $7,548 five years later. Meanwhile, the other rungs keep running on their own clocks.
What flexibility costs
A single 5-year GIC at 4.00% beats the ladder’s blended 3.75% in year one: the difference is 0.25 percentage points, or about $75 a year on $30,000. That is the price of having a rung come due every twelve months. If you are certain you will not touch the money for five years and rates feel attractive, one long GIC earns more; the ladder is insurance against being wrong about rates and about your own needs.
There is a second, quieter benefit. A ladder averages your reinvestment rate over time. If rates fall, most of your money is still locked in at the old, higher rates. If rates rise, a rung matures soon and gets reinvested at the new rate. You never have to guess which way rates will go.
Tax: where you hold the ladder matters
Inside a TFSA or RRSP, GIC interest is not taxed as it accrues. In a non-registered account, it is added to your income. At a 30% marginal rate, the ladder’s first-year $1,125 shrinks to about $788 after tax, and the savings account’s $825 to about $578. The ladder’s advantage survives tax, but both numbers are smaller. For money you plan to keep for years, using a registered account first is usually the biggest single improvement, larger than the difference between ladder designs.
The CDIC limit and a big ladder
Protection is $100,000 per depositor, per category, per member institution. A $30,000 ladder is comfortably inside it, but a $250,000 pile is not. You can split rungs across institutions, or across categories such as TFSA, RRSP and a non-registered account. Credit unions are protected by provincial deposit insurers with their own limits, and different rules. Verify membership with the institution before depositing.
When a ladder is not worth it
- You need the money soon. If a down payment is due in nine months, a savings account or a short GIC is the tool; a five-year ladder is not.
- Your balance is small. Some GICs require minimums, and splitting $3,000 into five pieces leaves each rung tiny.
- A promotional savings rate beats the GICs. Introductory rates sometimes top ladder rates for a few months. The calculator models this explicitly.
- Your real return is the problem. A GIC may pay 4% while inflation runs 3%; a ladder cannot fix a thin real return, though it does lock in a rate.
How to build your own
- Decide how much of your cash is truly surplus and how long you can leave it alone.
- Keep an emergency buffer, often three to six months of expenses, in a savings account.
- Split the rest into equal rungs across terms that fit your horizon.
- Note each maturity date in a calendar and decide in advance what you will do with it.
- Run the GIC & Cash Ladder Yield Optimizer with your own amount, horizon, account type and liquidity preference to compare against savings.
One last caution: all rates here are snapshots. By the time you read this, the numbers will have moved, and the arithmetic, not the rates, is what carries over.
