Operating Expense Reconciliation Calculator

At the end of each year, landlords compare actual operating expenses to the estimated payments tenants made throughout the year. If actuals exceed estimates, tenants owe a true-up payment. If estimates exceeded actuals, tenants receive a credit or refund.

Most leases give tenants 30 to 90 days to dispute a reconciliation statement. The clock typically starts from the date you receive the statement, not the statement date. After the deadline, your right to dispute may be waived, so always act quickly.

Most leases require reconciliation within 90 to 180 days after year end. If your landlord sends reconciliation statements late, check whether your lease provides a time limit; some leases void landlord claims submitted after a set deadline.

A refund calculation based on your own inputs is a starting point, not a verified claim. You will need to reconcile the number against the landlord's actual expense schedule, confirm your pro-rata share was applied correctly, and document any excluded expense categories. CAMAudit processes your actual reconciliation statement and lease, runs all 13 detection rules, and generates a dispute letter draft citing the specific overcharge line items your landlord needs to credit.
