Frequently Asked Questions
How accurate is this CAM overcharge estimate?
This calculator uses industry-average error rates to produce a probability-weighted estimate. It is not a substitute for a full audit that reviews your actual reconciliation statement and lease.
What error rates does the calculator use?
The calculator applies common CAM error probabilities across capital expense misclassification, gross-up errors, admin fee overcharges, non-CAM expenses, cap violations, and pro-rata share errors.
Why do I need to enter my email to see results?
We use your email to send the estimate resource and unlock the full calculator results for future visits.
What should I do if the calculator shows a large potential overcharge?
A large estimate means there is meaningful financial risk in your current CAM charges. The next step is a full CAM audit that reviews your actual reconciliation statement and lease terms.
Does this calculator work for NNN leases?
Yes. CAM overcharges can occur in triple net, modified gross, and full-service gross leases with expense stops.
