Verifying your pro-rata share requires two numbers: your leased square footage and the denominator your lease defines. The formula looks simple but the denominator definition is where errors hide. Anchor exclusions, management office exclusions, and variable versus fixed denominator definitions all affect the result. CAMAudit extracts the correct denominator from your lease and does the math.
TL;DR
A pro-rata error affects every line item in your reconciliation simultaneously; verifying it once catches overcharges across the entire CAM pool rather than one line at a time.
Who this is for
Tenants who want to understand the mechanics of their pro-rata share calculation or who have noticed that the percentage on their reconciliation differs from what their lease appears to require.
Who this is not for
Tenants with a negotiated fixed CAM amount that is not tied to a pro-rata formula, or tenants who have already confirmed their percentage with their landlord in writing.

CAMAudit extracts your lease-defined pro-rata formula, applies it to the figures in your reconciliation, and flags any discrepancy between your calculated share and the share used to bill you.
