| From: | To: |
The interest earned calculation determines how much additional money has been gained from an investment beyond the original principal amount. It represents the return on investment for the period the money was invested.
The calculator uses the simple interest earned formula:
Where:
Explanation: This formula calculates the difference between the final amount and the original investment to determine the interest earned.
Details: Calculating interest earned is essential for evaluating investment performance, comparing different investment options, and making informed financial decisions about where to allocate funds.
Tips: Enter the total amount received and the original principal invested. Both values must be in the same currency units and must be valid positive numbers.
Q1: Does this calculation account for compound interest?
A: No, this is a simple interest calculation that shows the total interest earned regardless of how it was calculated. For compound interest analysis, more detailed calculations are needed.
Q2: What currency should I use?
A: You can use any currency as long as both amount and principal are in the same currency units. The result will be in those same units.
Q3: Can this be used for negative interest?
A: Yes, if the amount is less than the principal, the calculator will show a negative value, indicating a loss rather than earned interest.
Q4: How does this differ from interest rate calculation?
A: This calculates the absolute interest amount, not the percentage rate. To find the interest rate, you would need to divide the interest by the principal and multiply by 100.
Q5: Is this applicable to all types of investments?
A: This basic calculation works for any investment where you know the starting principal and final amount, including savings accounts, bonds, and simple investment returns.
