Interest calculation is a fundamental financial concept that determines the cost of borrowing money or the return on investment. The two main methods are reducing balance interest and flat interest, each with different applications in financial products.
The calculator uses the following formulas:
Reducing Interest: Balance × Rate
Flat Interest: Principal × Rate
Where:
Explanation: Reducing interest calculates interest on the remaining balance, while flat interest calculates interest on the original principal throughout the loan term.
Details: Understanding different interest calculation methods is crucial for making informed financial decisions, comparing loan products, and managing personal or business finances effectively.
Tips: Enter the balance amount in currency, principal amount in currency, and interest rate in percentage. All values must be positive numbers.
Q1: What is the difference between reducing and flat interest?
A: Reducing interest decreases as the principal is paid down, while flat interest remains constant throughout the loan term based on the original principal.
Q2: Which interest method is better for borrowers?

Q3: Where is flat interest commonly used?
A: Flat interest is often used in short-term loans, personal loans, and some types of vehicle loans in certain markets.
Q4: How does reducing interest affect monthly payments?
A: With reducing interest, the interest portion of monthly payments decreases over time while the principal portion increases.
Q5: Can I use this calculator for investment returns?
A: While primarily designed for loan interest, the formulas can be adapted for simple interest calculations on investments.
