Stock Leakage Risk Calculator

This tool does not promise magic. It helps the owner name the control problem: where stock may be leaking, where transfers are unclear, where known losses should be separated, and where the business still depends on manual explanations instead of evidence.

Use your own count and transfer figures to estimate observed exposure. The calculator does not invent a leakage percentage and does not claim the result is theft or an audited financial loss.

Your inputs

Calculated exposure

Observed stock variance

Transfer discrepancy exposure

₦0

Unexplained exposure estimate

₦0

Formula

Observed variance = stock value × variance rate.

Transfer exposure = monthly transfer value × unresolved discrepancy rate.

Unexplained exposure = max(0, observed variance + transfer exposure − known approved losses).

Interpretation limits

The result is an exposure estimate from your inputs. It may include timing differences, data errors, unit mistakes, approved adjustments, damage, expiry, process failures, or theft. Investigate the movement trail before attributing cause.
