Earn up to 3.5% interest, 24/7.

How much interest $100,000 earns in a year in Canada depends on the interest rate.

At 3.5% annual interest, $100,000 would earn approximately $3,500 over one year, assuming the rate and balance remain unchanged. At 5%, the same $100,000 would earn about $5,000.

How Much Interest Does $100,000 Earn at Different Rates?

Here's approximately how much $100,000 could earn over one year:

  • 2% interest: $2,000

  • 3% interest: $3,000

  • 3.5% interest: $3,500

  • 4% interest: $4,000

  • 5% interest: $5,000

Your actual earnings can differ depending on whether the rate changes, how frequently interest is calculated and whether you deposit or withdraw money during the year.

How Much Does $100,000 Earn Per Month?

At a 3.5% annual rate, $100,000 works out to an average of about $292 in interest per month.

The actual amount credited each month may vary because some savings accounts calculate interest daily and pay it monthly.

Do You Pay Tax on Savings Interest in Canada?

Usually, yes. Interest earned in a regular, non-registered savings account generally needs to be reported as income on your Canadian tax return.

For example, if your $100,000 earned $3,500 in interest, that $3,500 would generally be considered taxable interest income if it were held in a regular savings account.

If the money is held in a TFSA and you have enough available contribution room, interest earned inside the account is generally tax-free.

Is $100,000 Worth Keeping in a High Interest Savings Account?

It can be if you want to keep the money accessible and avoid investment market risk. The interest rate makes a significant difference: the difference between earning 2% and 5% on $100,000 is $3,000 per year.

When comparing savings accounts, look beyond the advertised rate and check whether it is a regular or promotional rate, along with any fees, balance requirements or other conditions.
