Tax Free Savings Account Interest Rate Calculator

A Tax-Free Savings Account (TFSA) is a tax-advantaged investment account available in Canada. This calculator helps you determine how much interest you'll earn on your TFSA balance over time.

How the Calculator Works

The Tax-Free Savings Account Interest Rate Calculator estimates the future value of your TFSA based on the current balance, annual interest rate, and investment period. The calculation assumes the interest is compounded annually, which is typical for TFSA interest.

Note: This calculator provides estimates only. Actual results may vary based on market conditions and other factors.

The Formula

The calculation uses the compound interest formula:

Future Value = Initial Balance × (1 + Annual Interest Rate)^Number of Years

Interest Earned = Future Value - Initial Balance

Where:

Initial Balance = Your current TFSA balance
Annual Interest Rate = The expected annual return (expressed as a decimal)
Number of Years = The investment period

Worked Example

Suppose you have $10,000 in your TFSA, expect a 3% annual return, and plan to keep the money for 5 years.

Future Value = $10,000 × (1 + 0.03)^5 = $11,592.74

Interest Earned = $11,592.74 - $10,000 = $1,592.74

After 5 years, your TFSA would grow to approximately $11,592.74, earning $1,592.74 in interest.
