Formula Used

The tax calculator on savings account interest uses the following formula to determine the taxable portion of interest income:

Taxable Interest = Interest Earned × (1 - (Taxable Income / (Taxable Income + Interest Earned)))

Where:

Interest Earned = Total interest earned on savings account
Taxable Income = Your total taxable income for the year

This formula accounts for the progressive nature of income tax, where higher income brackets pay higher tax rates on interest income.

Worked Examples

Let's look at two examples to illustrate how the tax calculator on savings account interest works.

Example 1: Low Taxable Income

If you have $30,000 in taxable income and earn $500 in interest, the taxable portion would be:

Taxable Interest = $500 × (1 - ($30,000 / ($30,000 + $500))) = $500 × (1 - 0.983) = $15.50

In this case, only $15.50 of your interest income is taxable.

Example 2: High Taxable Income

If you have $150,000 in taxable income and earn $1,000 in interest, the taxable portion would be:

Taxable Interest = $1,000 × (1 - ($150,000 / ($150,000 + $1,000))) = $1,000 × (1 - 0.993) = $69.40

Here, $69.40 of your interest income is taxable.
