Worked Examples

Here are two examples of how the tax deduction calculator works:

Example 1: Medical Expenses

If you have $5,000 in eligible medical expenses and your total income is $60,000, the calculator would estimate your deduction as follows:

Calculation

Deduction Amount = ($5,000 / $60,000) × 100 = 8.33%

This means your medical expenses represent approximately 8.33% of your total income, which may qualify for a tax deduction.

Example 2: Charitable Donations

If you donated $2,000 to a registered charity and your total income is $70,000, the calculator would estimate your deduction as follows:

Calculation

Deduction Amount = ($2,000 / $70,000) × 100 = 2.86%

This means your charitable donations represent approximately 2.86% of your total income, which may qualify for a tax deduction.
