He meaning of TIN is that of nominal interest. The Nominal Interest Rate gives you the information cost of money borrowed in an operation. In other words, it represents the effective percentage that you have to pay beyond the capital amortization. This is the basic information you need to know how much you have to pay. You have to consider two factors, which are the type of interest and the return period.

This is a basic magnitude that must be used to rule out very expensive operations. Of course, to make a more approximate calculation, you can use other variables.

The differences between TIN and APR

Unlike the TIN, it takes into account the linked products, amortization costs, Bank fees and other amounts. This compound interest calculation formula lets you know what annual percentage you have to pay.
