Principal and Interest

Principal and Interest

"Principal" and "interest" are two key components of a mortgage loan.

The principal is the original amount of money borrowed or the outstanding balance of a loan. It represents the initial loan amount before interest is added.

Interest is the cost of borrowing money. It is the additional amount that the borrower pays on top of the principal as compensation to the lender. Interest is usually calculated as a percentage of the outstanding principal and is expressed as an annual percentage rate. The interest on a loan accrues over time and is a key factor in determining the total cost of the loan. In most loan payment structures, the interest portion of the payment is higher at the beginning of the loan term and decreases over time as the outstanding principal decreases.

When your interest-only period expires, you'll have to begin paying off the principal at the current interest rate. While interest-only payments are less expensive during the interest-only term, you'll pay more interest over the life of the loan.

The formula for calculating Principal amount would be P = I / (RT) where Interest is Interest Amount, R is Rate of Interest and T is Time Period.
