About Return on Interest Calculator (Formula)
The Return on Interest Calculator is a tool used to calculate the return on investment (ROI) or the rate of return on an interest-bearing investment. This calculator helps determine the profitability or effectiveness of an investment based on the interest earned.
The formula for calculating the return on interest depends on the initial investment amount, the interest rate, and the time period. The formula can be expressed as:
Return on Interest = (Interest Earned / Initial Investment) × 100
Where: Return on Interest = Return on investment as a percentage Interest Earned = Total interest earned from the investment Initial Investment = Initial amount invested or principal Note: The interest earned is calculated by subtracting the initial investment from the total amount received.
To use this formula, you need to know the interest earned and the initial investment amount. Divide the interest earned by the initial investment, multiply by 100, to obtain the return on interest as a percentage.
It’s important to note that the return on interest calculation provides a measure of profitability or return on an investment. It helps assess the effectiveness of an investment by comparing the interest earned to the initial investment.
