CAM Reconciliation Lag Calculator
Slow CAM recon costs NOI carry.
Carry cost from lag
$30,000
Dispute exposure
$216,000
Total NOI drag
$73,200
How the math works
Avg receivable = annual CAM / 2. Carry = receivable × rate × months/12. Dispute = annual × %.
$900k × 8% × 5/12 = $30k carry. $216k dispute × 20% loss = $43k NOI drag. Total $73k.

How this calculator works
What this page estimates
This CAM Reconciliation Lag Calculator is built to give a quick, browser-based estimate for cam reconciliation lag. Slow CAM recon costs NOI carry. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the cam reconciliation lag result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this cam reconciliation lag estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
What's the lag?
CAM year ends Dec 31. Actual expenses compiled. Reconciliation calculated vs pro forma. Billing/credit sent to tenants. Industry standard: 90-180 days. Fast operators: 60 days. Slow: 365+ days. Each month of lag = tenant receivable continues to accrue.
Cost of lag?
$1M annual CAM, 6-month lag: $500k float burden. At 8% cost of capital: $40k/yr carry cost. On large portfolios with many properties: millions annually. Tight reconciliation discipline recovers NOI.
Disputes?
10-15% of CAM charges disputed by tenants typically. Resolved via lease audit, negotiation, settlement. Budget 3-5% of CAM for writeoffs. Audit-friendly tenants (large chains) challenge more often; small tenants pay without review.
