# Calculate the ratio of capital to risk-weighted assets for a bank in Excel

There are many financial metrics that help determine a company’s financial health. One of the key financial metrics that regulators carefully scrutinize is a bank’s capital to risk-weighted assets ratio, or capital ratio.

This ratio measures a bank’s financial health by measuring its available capital as a percentage of its risk-weighted credit exposure. Its purpose is to protect depositors and promote financial stability. You can calculate a bank’s capital to risk-weighted assets ratio in Microsoft Excel after you have determined its Tier 1 and Tier 2 capital and risk-weighted assets.

## Definitions of variable terms

Contents

First we define our variables. A bank’s Tier 1 capital is its basic capital, which is used when it needs to absorb losses without going out of business. It includes equity and declared reserves. A bank’s Tier 2 capital is its Tier 2 capital, e.g. B. unreported reserves and subordinated liabilities. Tier 2 capital is less secure than Tier 1 capital. A bank’s risk-weighted assets are its risk-weighted assets used to determine the minimum capital required to reduce the risk of insolvency.

## The formula for the ratio of capital to risk-weighted assets

The formula for calculating the ratio of capital to risk-weighted assets is as follows

Risk-weighted assets = (Tier 1 capital + Tier 2 capital) / Risk-weighted assets)

## Calculate Risk Capital Ratio of Risk Weighted Assets in Excel

To calculate a bank’s capital to risk-weighted assets ratio in Excel, first enter “Tier 1 Capital” and “Tier 2 Capital” in cells A2 and A3. Then enter “Risk-weighted assets” in cell A4 and “Ratio of capital to risk-weighted assets” in cell A5.

Suppose you want to compare the ratios between two banks, Bank A and Bank B. Enter “Bank A” and “Bank B” in cells B1 and C1. Next, enter the appropriate values ​​for Bank A’s Tier 1 capital, Tier 2 capital, and risk-weighted assets in cells B2 through B4. Next, enter the appropriate values ​​for Bank B Tier 1 Capital, Bank B Tier 1 Capital, and Risk-weighted Assets in cells C2 through C4.

The resulting ratio of capital to risk-weighted assets for bank A is calculated by entering the formula “=(B2+B3)/B4)” in cell B5. Bank B’s capital to risk-weighted assets ratio is calculated by entering the formula “=(C2+C3)/C4)” in cell C5.

## The essential

Once a person calculates a bank’s ratio of capital to risk-weighted assets, they can use it to assess whether the bank has enough capital to absorb potential losses before it defaults and loses depositor funds. It is essential for a bank to monitor this ratio in order to know its capital position and meet its financial obligations. If all banks comply with this ratio and take the appropriate measures, a public finance collapse can be avoided in the event of an economic downturn. Banks with a high ratio of capital to risk-weighted assets are considered safe and financially stable.
