Customer concentration calculator

Measure how much of your receivables depends on your largest customers and see where concentration risk is building.

The assessment helps commercial-credit teams examine customer concentration across accounts receivable, including the share represented by top customers and an approximate concentration index.

Concentration should be reviewed alongside payment behavior, aging, disputes, expected sales, customer groups, available insurance, security, and the institution's documented risk appetite.

The result is directional and should not replace verified receivables data, independent credit analysis, approved limits, or portfolio governance.

Teams should document source dates, currencies, disputed balances, customer-group treatment, exclusions, and ownership for any resulting limit or collection review.
