Frequently asked questions


What does the loan calculator show?
Monthly payment, total amount paid over the loan term, total interest paid, and an amortization breakdown showing how each payment is split between principal and interest.


Is this for mortgage calculations as well?
Yes. Mortgage calculations use the same formula. Enter the loan amount, interest rate, and term in months.


Does it account for compound interest?
Yes. Standard loan amortization uses compound interest calculated monthly, which is the standard for mortgages and personal loans.


Why is the total interest so high on a long loan?
Long-term loans with moderate interest rates can result in paying significantly more in interest than the original principal. This is the mathematical reality of compound interest over time.


Does it include insurance or fees?
No. The calculator shows principal and interest only. Add any fees or insurance costs separately.


Does it work offline?
Yes.
