What is the analized rate?

Roční sazba je způsob, jak vyjádřit úrokovou sazbu z půjčky nebo investice. Zahrnuje to převzetí skutečné sazby, která bude zaplacena a obnovení, jako by doba půjčky byla přesně jeden rok. To se často provádí u půjček, které vydrží méně než rok. Cílem je usnadnit porovnání různých možností půjčky. Například věřitel může nabídnout půjčování 100 USD (USD) za měsíc, s celkovým splátem 105 $. Zdá se, že se jedná o úrokovou sazbu 5%, což zní pro půjčku dobrou hodnotu. Roční sazba by však byla 12krát vyšší než 60%. To je výrazně více než většina bankovních půjček nebo kreditních karet. These include the so -called "payday" loans, which are short -term loans that are usually provided to people with low incomes who try to live from paycheck after paycheck. Taková půjčka by mohla půjčit100 $ za týden se splátem 125 $. Na první pohled se náklady 25 $ nemusí zdát být přehnané. Vyjádřeno jako anualizovaná sazba, to by však bylo 25% krát 52, což je v celkové výši 1 300%.

In many countries, creditors are obliged to provide customers with the details of the analized rate they pay. This is to allow a fairer comparison of different sources of finance. Without this requirement, customers would only have to work from the "title" rates, which are the numbers that companies voluntarily use in advertising. For example, a loan for a paycheck can advertise a flat fee for an interest fee, a credit card company can advertise a monthly interest rate, and a bank loan may indicate an annual rate. Companies are usually still allowed to provide these data if the annual rate is also in detail.

There are several different ways to calculate the analized rate that differs depending on how interest is taken into account. The two main ones are the nominal annual percentage, known as APR, and the annual equivalent rate, AER. APR is calculated as in the examples of the above.

Aer BERE consideration of the effects of compound interest. This reflects the fact that the interest fee of each period is based on the full outstanding amount of the loan, which includes any interest that has already been used in previous periods and has not yet paid. This means that the debtor can pay interest on previous interest. The exact method for calculating AER may vary, but will usually be standardized where creditors are legally obliged to display it.
