What is an amortized loan? - definition of depreciation
Loan amortization is the gradual reduction of the borrower's debt due to regular payments of principal and interest. The payment schedule is fixed in the loan agreement between the lender and the borrower.
For example, if you took out a loan for 100 thousand dolars and have already repaid 10 thousand dolars from the main debt, then the amortization of your loan was 10%. Traditionally, two systems of loan payments (loan amortization) are used - annuity and differentiated.
Loan amortization formula
The following formulas are used for financial calculations related to loan amortization:
Monthly repayment formula:MP = \dfrac{A*i*(1+i)^n}{(1+i)^n-1}
- MP - monthly payment amount
- A - loan repayment amount
- i - periodic interest rate
- n - number of periods
Formula for unpaid balance:B = \dfrac{A*(1+i)^n-MP}{i((1+i)^n-1)}
- B - unpaid balance
- A - loan repayment amount
- i - periodic interest rate
- MP - monthly payment amount
- n - number of periods
- Mortgage, Loan, Debt management
