Basel III Calculator

The ABA has developed a calculator  to help bankers assess the impact of upcoming Basel III regulations. The calculator allows bankers to input information about their bank and see the changes to their risk-weighted assets under the new rule, as well as assess the impact on their capital ratios and the additional capital required to reach their target capital ratios.

The tool requires you to enter a number of inputs for their various asset categories. Due to the definitional changes associated with the new rule it is impossible to automate the calculator with currently reported data.

The purpose of this tool is to provide bankers a manageable way to evaluate the impact of upcoming capital rules. The calculator is not a substitute for reading and understanding the Basel III rule. This calculator is designed to provide accurate and authoritative information in regard to the subject matter covered. It is provided with the understanding that the publisher is not engaged in rendering legal, accounting, or other professional service. If legal advice or other expert assistance is required, the services of a competent professional should be sought.

We welcome feedback as we work to improve the calculator and better serve our member banks.
