Why must I enter the ongoing rate after a promotion?

A temporary promotional rate applies only during its stated period. The ongoing rate determines the rest of the first-year comparison, so omitting it can materially overstate the value.

Is savings-account interest taxable in Canada?

Interest in a regular non-registered savings account is generally taxable. Interest earned inside a TFSA is generally tax-free, subject to account rules and available contribution room.

Common questions

What the result does—and does not—mean.

Why is the ongoing rate required?

A promotion covers only part of the year. The remaining months can reverse the apparent advantage.

Why subtract monthly fees?

A higher rate can still lose when its annual fee exceeds the extra interest on your balance.

Is savings interest taxable?

FCAC says interest in a regular savings account is generally taxable. A TFSA estimate avoids the tax haircut but still depends on your eligibility and contribution room.

Does Bremo verify the rates I type?

No. Typed rates are your estimates. Verify current provider terms before making a decision.
