Q1: How is flat rate interest different from reducing balance interest?
A: Flat rate interest is calculated on the original principal throughout the loan term, while reducing balance interest is calculated on the outstanding principal, which decreases as payments are made.
Q2: Is flat rate interest better for borrowers or lenders?

A: Divide the percentage rate by 100. For example, 5% becomes 0.05, 7.25% becomes 0.0725.
Q4: Can flat rate interest be used for partial years?
A: Yes, the tenure can be entered as fractional years (e.g., 0.5 for 6 months, 1.5 for 18 months).
Q5: Does this calculation account for compound interest?
A: No, flat rate interest calculation is based on simple interest and does not incorporate compounding.
