A: Most modern home loans use compound interest, but simple interest calculations are useful for understanding basic interest concepts and some specialized loan products.
Q3: Can time be entered in months instead of years?
A: For accurate results, convert months to years (divide by 12) before entering the value.
Q4: Does this calculator account for additional fees or payments?
A: No, this calculator only computes simple interest. It doesn't include additional fees, taxes, or extra payments that might affect the total cost.
