What are Shariah financial ratios?

An explanation of the common financial ratios used to screen shares for Shariah compliance.

The short answer

Shariah financial ratios are numeric tests applied to a company’s accounts to limit exposure to interest-based financing or non-permissible income. Typical ratios look at debt levels, interest-bearing assets and the proportion of non-permissible revenue.

Typical ratios explained

Commonly used thresholds include limits on interest-bearing debt relative to market value, and limits on non-permissible income as a share of total revenue. Each provider may calculate these slightly differently.

Shariah-compliance considerations

Our platform uses AAOIFI Shari'ah Standard No. 21 as a practical default benchmark for shares. Practically that means: non-permissible income under 5% of total income; interest-bearing debt ≤30% of market value; interest-bearing cash/securities ≤30% of market value. Provider data source and calculation conventions can change results.

What this means in practice

  1. 1Read a fund or vendor’s explanation of how they calculate each ratio.
  2. 2Check the date of the financials used and whether adjustments are applied.
  3. 3If ratios are close to a threshold, expect that updates could change compliance status.
