The biological payment for repayment of a capital amount invested in a property for a specific period is called amortisation. It involves gradual reduction of the loan value through regular and equal payments.
Step-by-step explanation:
The biological payment for repayment of a capital amount invested in a property for a specific period is called amortisation. Amortisation is a method of gradually reducing the value of a loan or an asset, such as a property, over time through regular and equal payments.
For example, if a family takes out a 30-year mortgage loan to purchase a house, they will make monthly payments over the course of 30 years to repay the loan. Each payment includes both the principal amount borrowed (capital amount invested) and the interest charged by the bank. The payments are spread out evenly over the 30-year period, allowing the borrower to gradually repay the loan while also covering the interest charges.
Amortisation is commonly used in real estate and loan agreements to help borrowers manage their repayment obligations and banks to track the value of their assets.
