The interest rate is the remuneration for a loan of money made by one economic agent to another.

The sum borrowed is called the capital. The sum to be repaid is therefore the capital plus interest.

The interest rate is a rate used to calculate the interest on a loan.

Yes, there are 2 types of rate:

Fixed-rate loan: This is a loan where the interest rate does not vary throughout the term of the loan. The quid pro quo for this security is usually a slightly higher rate than the variable rate.

Variable-rate loan: this is a loan interest rate that can vary during the term of the loan, either upwards or downwards, depending on changes in the index used in the loan contract.

This is a rate that is fixed for a certain period and at the end of that period must be reviewed by the customer and the bank. The decision is taken by the customer and the bank whether to continue with a fixed rate for a given period or a variable rate for the same period. In general, if the customer does not come forward, the fixed rate is tacitly renewed for the same period as at the start.

This is the sum that the future owner is prepared to inject on his own or that the bank may require, in which case it will be a criterion for validating the loan.

The amount remaining to be paid once the monthly instalments already paid have been deducted. This is the amount to be paid first to repay the capital.
