Answer:
Principal
Explanation:
The principal of a loan is the capital that the debtor receives from the creditor. On that amount, interest payable is calculated.
The principal is one of the central axes of a loan, along with the interest rate, which is the cost of money, and the number of installments. All these elements allow to determine the payment schedule.
Each monthly installment has two components: Financial amortization (return of a portion of the capital received) and accrued interest. The latter are calculated by multiplying the interest rate of the credit by the balance of the principal that remains to be paid.
