This tool helps you calculate the interest on your savings after accounting for taxes.
Interest Calculator with Tax
This calculator allows you to calculate the compounded interest on a principal amount over a certain period of time, factoring in an annual interest rate and a tax rate on the interest earned. You can also specify the number of times the interest is compounded per year.
How to Use
- Enter the Principal Amount in dollars.
- Enter the Annual Interest Rate as a percentage.
- Enter the Time in years for which you want to keep the principal invested.
- Enter the Tax Rate as a percentage on the interest earned.
- Specify how many times the interest is compounded per year (default is 1).
- Click the Calculate button to see the results in the table below the form.
How It Calculates
The calculator first computes the compounded interest using the formula:
A = P (1 + r/n) ^ (nt)
where:
- P is the Principal Amount
- r is the Annual Interest Rate (in decimal form)
- n is the number of times the interest is compounded per year
- t is the Time in years
The total interest earned is then found by subtracting the principal from the compounded amount. The tax amount is calculated by applying the tax rate to the interest earned. The net amount earned after tax is found by subtracting the tax amount from the total interest earned.
Limitations
This calculator does not account for any other fees or penalties that may be applied to the interest earned. The calculations assume a constant interest rate and tax rate throughout the specified time period.
