How to Use the Basel Index Calculator

Choose the currency, then enter total capital and risk-weighted assets. Both amounts should use the same currency and reporting basis.

The result is capital as a percentage of risk-weighted assets. The calculator also displays both inputs with the selected currency symbol for easier checking.

Formula and Method - Basel Index Calculator

Basel index = (capital ÷ risk-weighted assets) × 100%

Risk-weighted assets convert assets into a risk-adjusted denominator. Dividing capital by that denominator gives a rough view of the bank’s loss-absorbing buffer. The 8% and 10.5% cues are reference points, not a full regulatory test.

Use Cases for the Basel Index Calculator

  • Calculating a capital-ratio style metric from disclosure data.
  • Testing how capital changes or RWA changes affect the ratio.
  • Teaching the relationship between capital and risk-weighted assets.

Frequently asked questions about Basel Index Calculator

Does currency affect the percentage?

No. If both inputs use the same currency, the ratio is unchanged; the currency is for display.

Are risk-weighted assets the same as total assets?

No. RWA adjusts assets by risk weight and usually differs from balance-sheet total assets.

Is this a formal regulatory capital ratio?

Not necessarily. Formal ratios depend on capital tiers, deductions, and local rules.
