This tool will help you calculate the interest earned on your investment after accounting for taxes.
How to Use the Interest Calculator with Tax

- Principal Amount: The initial amount of money that you have or plan to invest.
- Annual Interest Rate (%): The percentage rate at which your principal will earn interest each year.

Calculation Methodology and Limitations
The calculator uses simple interest calculation annually. It considers interest compounding at the end of each year. The tax is computed on the interest earned each year before adding to the principal for the next year’s calculation. While this provides a detailed and realistic scenario, it has some limitations:
Limitations:
- The interest rate and tax rate are assumed to remain constant throughout the entire period.
- Interest is compounded annually only, which may not represent more frequent compounding intervals.
- The calculator does not handle irregular payments or withdrawals from the principal amount.
