How to calculate interest on deposits in a bank?

Today the question of how to calculate interest on deposits is not difficult for those who have the Internet and plans to place their money in a technically advanced bank. Such a credit institution, as a rule, places a calculator on the page of each type of deposits, which indicates how much money will be received, based on the amount invested, the interest rate and the terms of the deposit.

Before calculating interest on deposits, it makes sense to study in detail the terms of the contract. For example, there are deposits, where a relatively high percentage is charged only if the amount "dolzhela" strictly to the end of the term. For example, if you put 100 rubles at 5 percent for 1 year, then by the results of the year you will receive 100 x 0.05 = 5 rubles. In the event that the money is withdrawn prematurely from the deposit, the amount can be 2 rubles, because For this situation, interest is provided at a reduced rate (fixed or expressed in fractions of the figure specified in the conditions).

It's another matter, if the terms of the contract provide for the accrual of interest for a period of less than a year. How to calculate interest on deposits in this case? To do this, use the following formula: B * (1 + P * K \ D \ 100) n - K, where K is the sum of the contribution, P is the interest rate, K is the number of days in each accrual period (month, quarter) - the number of days in a year (365, 366), n - the number of accruals in a year (for a monthly charge - 12, for a quarterly - 4).

If interest is included in the amount that has already been calculated for the previous period, then the interest is calculated according to the formula: B multiplied by (1 + П \ 100 \ н), where the expression in parenthesis is raised to the power of n. For example, you put 100 rubles at 10% per annum with interest on a monthly basis, which you do not withdraw. Interest in this case will be received as 100 * (1 + 10 \ 100 \ 12), the figure in parenthesis is raised to 12 degree.

Some credit institutions offer different interest rates on deposits for different categories of the population within the same program. Sberbank, for example, in some cases, determines higher rates for people of retirement age (women from 55, men from 60 years). The general rule is this: the larger the deposit amount and the longer it is in the bank, the higher the interest. However, in the long term, other factors can influence the proposed rates, including:

1. The general economic situation. The better the economy develops, the more demand for loans, the higher the rate that banks can offer their depositors.
2. Stability of the national currency. The less stable the ruble, the greater the inflation, the higher the interest on deposits.
3. Financial condition of a particular financial organization and the system as a whole. If the credit institution has issued too many loans, then it may have a cash deficit, which entails such a phenomenon as high interest rates on deposits. Large financial structures, as a rule, do not offer improved conditions. They do not have to "pay extra" to their customers for the risk.
4. Features of the tax policy of the state, the activities of the regulatory body, etc.

Recently, the emergence of "virtual" banks, which exist only as a page of the Internet. They can offer extremely high interest on deposits and other preferences. In this case, it is better to check the presence of such an organization on the Central Bank website, verify the TIN data, license numbers, the correctness of the name, availability of office premises, personnel, Otherwise you can give money to the swindlers, and then the question "how to calculate interest on deposits" can be postponed for an indefinite period.
