What is a high-interest savings account?

With the cost of pretty much everything trending up over the last few years, most of us are looking for smarter ways to maximize our hard-earned cash. But building a solid financial foundation isn’t just about pooling funds—it’s about stretching every dollar further.

Enter the high-interest savings account (HISA). You’ve probably heard the phrase “make your money work for you.” That's exactly what a HISA does best. Here is everything you need to know about how high-interest savings accounts work and how they differ from other accounts.

What is a high-interest savings account?

As the name suggests, a high-interest savings account offers significantly higher earnings than a traditional savings account. While a standard big-bank savings account might offer a rate of up to 1% (or worse, 0.05%), a good HISA gives you meaningful return. 

High-interest savings accounts work through compound interest. This means you earn not only on the cash you deposit, but also on the interest you’ve already earned from previous months. Depending on the financial institution, interest can compound daily, monthly, or annually.

For example, with the Neo Savings account, earnings are calculated daily on the total closing balance. Earnings are then paid out monthly¹, giving you a steady, compounding boost every single month.

As those monthly payouts start to accumulate, it is important to understand how they impact your annual return. Is interest in a savings account taxable? In short, yes. Any earnings you make from a high-yield account is considered taxable income by the CRA, which is why many savers also look into tax-sheltered alternatives.

High-interest savings account vs. other account types

Looking to park your money safely? You have options. Here is how a HISA compares to the other financial tools in your kit:

High-interest savings account vs. regular savings accounts

Standard savings accounts and HISAs look similar on paper, but the interest gap is massive. Some big traditional banks offer flash-in-the-pan promotional interest rates to get you through the door, only to drop your rate down to next-to-nothing a few months later.

High-interest savings account vs. chequing accounts

Chequing accounts are built for your day-to-day transactions—think paying bills, depositing paycheques, and buying groceries. Chequing accounts are essential, but they typically earn zero interest. Think of your chequing account as your financial transit hub, and your HISA as the destination where your savings go to grow.

High-interest savings account vs. guaranteed investment certificate

A guaranteed investment certificate (GIC) is a safe way to lock in a guaranteed return over a fixed period—anywhere from a few months to several years. The major difference between a HISA and a GIC comes down to flexibility.

With a HISA, your money is completely fluid. You can access it whenever you need it. With a traditional GIC, your money is locked away until it matures, and taking it out early usually means facing a penalty.

High-interest savings account vs. tax-free savings account

The tax-free savings account (TFSA) is often misunderstood. Despite its name, it's not actually a type of savings account—it's a tax-sheltered wrapper that can hold different types of investments like stocks, ETFs, mutual funds, or even a high-interest savings account. Any growth inside it is completely tax-free—no tax on interest, dividends, or capital gains.

A standalone HISA, in comparison, is unregistered. This means that the interest you earn counts as taxable income. What it lacks in tax perks, however, it makes up for in flexibility. HISAs have no annual contribution limits, no penalties for withdrawing and re-contributing, and no eligibility restrictions beyond basic age requirements.

High-interest savings account vs.registered retirement savings plan

The registered retirement savings plan (RRSP) is designed to help Canadians save for retirement. Contributions to your RRSP reduce your taxable income, and any interest or investment income you earn on funds in your RRSP is also exempt from taxation—as long as the funds remain in the RRSP account. You must pay taxes when you withdraw money from your RRSP account.

Like a TFSA, you can purchase various financial products in your RRSP—think stocks, bonds, mutual funds, and more. Since you have a longer timeline, you can worry less about investment fluctuations.

What are the downsides of a HISA?

While a high-interest savings account is a powerful tool to accelerate your financial growth, it’s also important to consider its downsides. Understanding both the pros and cons helps you make a more informed decision about whether it’s the right type of account for you. Here are some cons of a high-interest savings accounts worth considering:

Potential transaction fees

Some financial institutions charge fees for making transactions directly from a high-interest savings account, which may not make it ideal for paying off bills or making daily transactions. Instead, consider an account like Neo Chequing, which gives you cashback on essential spends and charges no fees.

Lower risk

Ready for more risk? You may want to look beyond a HISA. While savings accounts are great for saving for short-term goals, exploring products or stocks or ETFs might be worth considering if your timeline is longer than five years. Just remember that higher returns come with market volatility—and unlike a HISA, your principal can fluctuate.

Fluctuating interest rates

The interest rate of a HISA can fluctuate over time. Several factors come into play, like competition and the Bank of Canada’s policy interest rate. Learn more about high-interest savings account rates and the factors that affect them. 

What to look for when choosing a high-interest savings account

Not all HISAs are created equal. When shopping around, keep these in mind:

• Stable rates: Introductory or promotional rates may expire, while ongoing rates don’t. Check out our comparison of the best high-interest accounts in Canada to see which offer the most competitive ongoing rates. 
• Compounding frequency: This refers to how many times you receive the accumulated interest in your savings account. The higher the interest compounding frequency, the more interest earnings you get each year.
• Safety first: Your deposits should be backed by the Canada Deposit Insurance Corporation (CDIC²) up to $100,000. Don't skip this check.
• Fine print on fees: Some institutions promise a high rate in exchange for monthly fees or transaction costs. Look for an account with $0 monthly fees so every cent stays in your pocket.
• Accessibility: Look for a HISA that allows you to move money instantly, seamlessly, and for free.

Who should open a high-interest savings account

There are several situations in which a HISA may be ideal for your funds and financial situation. Some of these scenarios include:

• Starting an emergency fund
• Saving for short-term goals like paying off a car loan or building up a vacation fund
• Large but predictable expenses
