How Does Loan Interest Work Monthly?
Loan interest is usually calculated monthly, even if the rate is given annually.
Annual vs monthly interest
Lenders convert annual interest rates into monthly rates by dividing by 12.
How it is applied
Each month, interest is calculated on the remaining loan balance.
Example
A 6% annual interest rate becomes 0.5% per month. This rate is applied to your remaining balance.
