Many customers of commercial banks believe thatIt is impossible to calculate the interest accrued on a loan or deposit independently at home. And they are mistaken. In fact, if you know exactly the size of the bet and the principle of its accrual, you can do it in just a few minutes, using only a calculator and a sheet of paper.
If a person does not understand how to calculate intereston the loan, of course, he can add to the payment and extra. However, in most cases it turns out that the borrower is not right in his suspicions, simply by giving away his blood every month, one can involuntarily become paranoid. Therefore, if there is a suspicion that money goes unclear where, it is better to take a printout in the bank and check. Before calculating interest, you should carefully study the loan agreement in order to understand exactly how they are accrued: on the actual balance of the debt, on the estimated balance on the schedule or on the original loan amount. In most banks, the first option is used, but there may be others.
In general, ideally the contract and the principle of chargingpercent should be studied before the transaction is formalized, and not after some time, but if this did not happen in time, it is better to do it later than not to do at all. In fact, the interest on the loan - this is the main income of the bank, obtained from this type of transactions. But the client must understand that he may not be the only one. There are many other ways (and quite legitimate) of taking money away from citizens. Therefore, before you blame on unreasonably accrued interest, you should make sure that it is they, and not some "commission for monitoring the transaction."
If the client has studied the contractbank statement and understood that there should not be any additional charges, you can start calculating. Of course, it takes a lot of time to check all the data for a year or more. But you can do with less radical measures, after considering several months selectively. It should also be noted that the principle of how to calculate interest on a transaction does not depend on the repayment schedule. That is, in the case of an annuity, and with the classical version of lending, the accruals are carried out identically. The only thing that can differ in different situations (this is necessarily spelled out in the contract), the number of days in a calendar year. As a rule, banks consider that there are 360 of them, but in some cases there may be 365.
To get the amount of interest due topayment in the current (or any other) month follows the balance on the loan body (you can see it in the statement) multiplied by the annual rate, divided by the number of banking days and multiplied by their number in the period under study. For example, with a balance of 30,000 monetary units, a rate of 10% per annum for October (31 days in it) should be credited with 258.33 units. This is subject to the condition that the year 360 days. And seeing in the statement a different value, you need to ask the specialist why.
If the client does not know how to calculate interest oncontribution, it can, in principle, do the same. The deposit agreement also describes the principle of accrual. The only thing you need to take into account is the availability of capitalization. If it is stipulated by the contract, the calculations will be a little more complicated, and outside help may be needed.
