Bank Capital Adequacy Ratio: Calculate regulatory capital relative to risk-weighted assets.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Bank Capital Adequacy Ratio to answer this question: calculate regulatory capital relative to risk-weighted assets? Enter Eligible regulatory capital, Risk-weighted assets, Required minimum including buffers; the calculator shows Capital adequacy ratio. Try changing one number and watch what happens to Capital adequacy ratio. The answer tells you Capital adequacy ratio.
Age 15Explain it to a 15-year-oldConnect it to the formula
Regulatory definitions, deductions and required buffers vary, so published capital ratios should follow the applicable framework. The rule is Capital adequacy ratio = eligible regulatory capital ÷ risk-weighted assets. Its input values are Eligible regulatory capital, Risk-weighted assets, Required minimum including buffers (%), and the main result is Capital adequacy ratio. Try changing one number and watch what happens to Capital adequacy ratio.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a macroeconomics relationship while holding unmodelled conditions constant. The implemented relation is Capital adequacy ratio = eligible regulatory capital ÷ risk-weighted assets, evaluated from Eligible regulatory capital, Risk-weighted assets, Required minimum including buffers (%) to produce Capital adequacy ratio. Regulatory definitions, deductions and required buffers vary, so published capital ratios should follow the applicable framework. The result depends on comparable definitions, units, populations and time periods. It estimates a relationship; it does not establish causation or replace current primary data.
The economic question
Calculate regulatory capital relative to risk-weighted assets.
Why this relationship is useful
Regulatory definitions, deductions and required buffers vary, so published capital ratios should follow the applicable framework.
Inputs that must be comparable
- Eligible regulatory capital.
- Risk-weighted assets.
- Required minimum including buffers measured in %.
Use one market, firm, population and time period throughout; mixing definitions can make a correctly calculated number economically meaningless.
The model
Capital adequacy ratio = eligible regulatory capital ÷ risk-weighted assets
From inputs to output
The calculator combines Eligible regulatory capital, Risk-weighted assets, Required minimum including buffers and reportsCapital adequacy ratio together with Buffer above entered minimum, Capital required at minimum. Change one assumption at a time to identify what actually drives the estimate.
How to read Capital adequacy ratio
Read the sign, magnitude, unit and period together. The result quantifies the relationship in “calculate regulatory capital relative to risk-weighted assets”; it does not by itself prove that one input caused another.
Where interpretation can fail
Do not use the result when the input definitions, units or formula assumptions do not match the real situation. This is an educational model, not financial, investment, tax or policy advice; verify material decisions against primary data and professional guidance.
