A headline rate advertising “up to 4.6 percent” on an FHSA savings balance almost never means you’ll actually earn 4.6 percent for a full year. In 2026, that kind of number is typically a promotional rate lasting somewhere between 90 and 180 days, after which the account quietly resets to a much lower ongoing rate, sometimes dropping below 1 percent once the promotional window closes. The ongoing rate, not the promotional headline, is what actually determines how much your FHSA balance grows over any meaningful stretch of time.

Understanding exactly how these rates get calculated, what genuinely matters when comparing one provider against another, and how compounding actually affects your real return is worth working through before assuming the biggest number you see advertised is automatically the best deal.
Promotional Rates And Ongoing Rates Are Genuinely Different Products
A promotional rate is a temporary offer, usually reserved for new deposits and running for a fixed window, three to six months being common, specifically designed to attract new account holders. Once that window closes, the balance reverts to the institution’s ongoing rate, the figure that actually applies for as long as your money genuinely sits in the account afterward. A provider offering a strong ongoing rate with no promotional gimmick at all can genuinely outperform a competitor’s flashier promotional headline once you account for what happens after the introductory period ends.
Take an $8,000 FHSA balance sitting in an account offering a 4.6 percent promotional rate for the first 90 days, then dropping to a 2.75 percent ongoing rate for the rest of the year. That combination earns roughly $256 in interest across the full year. A separate account offering a flat 2.75 percent rate with no promotional period at all would earn about $220 over the same year on the identical balance, meaning the promotional account still comes out ahead here, but by a much smaller margin than the headline 4.6 percent figure alone would suggest. The gap narrows further, or reverses entirely, the longer you actually hold the balance beyond that first year.
How The Interest Actually Gets Calculated Day To Day
Most Canadian cash savings accounts, including FHSA cash balances, calculate interest daily based on your closing balance and compound it monthly, meaning each month’s earned interest gets added to your principal before the next month’s interest is calculated. This produces a small but genuinely compounding effect over time, distinct from how a GIC often works, where interest can be paid only at maturity or compounded specifically on the account’s anniversary date rather than every month.
The actual stated interest rate itself matters considerably more to your real return than the specific compounding frequency does, since the gap between two genuinely different rates almost always outweighs the difference between monthly and daily compounding at the same rate. A meaningfully higher rate compounded less frequently will still generally beat a lower rate compounded more often, which is exactly why comparing the actual percentage on offer matters more than getting distracted by which specific compounding schedule a provider advertises.
What To Actually Check Before Choosing Based On Rate
Confirm whether the number you’re looking at is genuinely the ongoing rate or a temporary promotional one, and specifically how long that promotional period actually lasts before it resets. Check whether the rate requires a minimum balance, a specific account tier, or a monthly fee to access, since a headline rate that only applies above a high minimum balance, or that comes attached to a paid account tier, isn’t a genuinely comparable offer against a provider offering the same rate with no such conditions.
The Rule of 72 offers a quick, useful way to make sense of any rate you’re actually comparing, dividing 72 by the annual interest rate gives you a rough estimate of how many years it takes your balance to double at that rate held consistently. At a 4 percent rate, that’s roughly 18 years, a useful gut check for understanding just how modest even a genuinely strong savings rate looks over the kind of shorter timeline most FHSA holders are actually working with before an eventual home purchase.
Your Cash Balance Is Genuinely Protected Regardless Of Rate
Whatever rate you end up choosing, cash and GICs held within an FHSA at an eligible financial institution are covered by the Canada Deposit Insurance Corporation up to a combined $100,000, protecting your actual principal regardless of which specific provider or rate you’ve chosen. This coverage is worth confirming directly for your specific institution before assuming it automatically applies, since not every platform holding an FHSA is structured the same way for CDIC eligibility purposes.
That insurance coverage means the rate comparison genuinely comes down to maximizing return rather than weighing safety tradeoffs between one CDIC-eligible provider and another, provided your total balance stays within that coverage limit. For most FHSA holders working within the $40,000 lifetime contribution limit, that $100,000 threshold leaves comfortable room regardless of which specific rate ends up winning out.
Comparing Rates The Right Way For Your Own Situation
Confirm the actual ongoing rate, not just the advertised promotional headline, before assuming a specific provider’s cash FHSA is genuinely the best option for your balance. If you’re weighing a cash based FHSA against holding GICs instead, our breakdown of FHSA GICs and investment options covers how GIC rates and terms work differently from a straightforward cash savings rate, worth reading alongside this piece before deciding where your contribution room should actually sit.
And if you haven’t yet settled on which institution to open your account with at all, our comparison of the best FHSA accounts in Canada covers how rate structures differ across the providers most commonly compared against each other.
What People Get Wrong About FHSA Interest Rates Most Often
Is a higher promotional rate always worth choosing over a lower flat ongoing rate? Not automatically, since the actual value depends on the promotional period’s length and how it compares against the ongoing rate that follows, and a genuinely strong flat rate with no promotional gimmick can outperform a flashier promotional offer once the full picture is calculated.
Does interest earned inside an FHSA get taxed the way interest in a regular savings account does? No, interest earned inside an FHSA grows tax sheltered the same way it does inside an RRSP or TFSA, with tax treatment only becoming relevant based on how the money is eventually withdrawn, not on the interest itself as it accumulates.
Do all FHSA providers offer interest on cash balances? No, some platforms specifically built around self-directed investing don’t pay interest on uninvested cash sitting in the account at all, which is exactly why confirming whether interest is even offered, before comparing the specific rate, matters as the first step.
