FAQ
Q: What is the difference between compound and simple interest?
A: Simple interest is calculated only on the principal, while compound interest adds interest to the principal for subsequent calculations, leading to significant differences over time.
Q: How to adjust repayment frequency?
A: In the "Term" option, select "Months" and enter the total number of months; the tool will automatically compute the monthly repayment plan.
Q: Does the result include fees?
A: No. The tool only calculates interest and principal; other fees must be added manually.
