Calculation of the annual percentage rate of charge

Updated last 26.03.2021

What is the annual percentage rate of charge?

In order to find out exactly how much a business loan from one bank or another cost, you have to calculate the annual percentage rate of charge (APRC). In accordance with art. 19, para 1 of the Consumer Credit Act this is an indicator that calculates the total costs under the loan, present or future (interest, other direct or indirect costs, commissions, remunerations of any kind, including those due to intermediaries arranging the signing of the agreement), expressed as annual percentage rate of charge of its amount. The bank provides the APRC in the general terms and conditions on the loan.

How is the annual percentage rate of charge calculated?

This is an objective indicator of the cost of your loan. It is calculated by adding up all costs you will incur in the form of outflows on the loan and which you will pay to the servicing bank, divided by the weighted average base of its amount over the entire term of the loan.

The Consumer Credit Act, Appendix No 1 to art. 19, para 2 provides a formula and additional information as to how to calculate mathematically the annual percentage rate of charge. It should be taken into account that the stated provision is applicable only in relation to the consumer credits. As for the other credits there is no legally set formula.
