Dark Store Co Tenancy Cost Calculator
Dark stores trigger cotenancy even while paying. This calculator sizes.
Net NOI loss over dark period
$975,000
Small tenant abatement loss
$975,000
Anchor rent offset
$1,050,000
How the math works
Abatement loss = tenants × rent × % × months/12. Anchor continues paying = offset on paper. Net NOI loss = abatement (anchor rent continues and is needed baseline).
20 shops × $65k × 50% × 1.5 yr = $975k abatement. Anchor keeps paying $1.05M. Net NOI decline from base = ~$975k. Large hit despite anchor rent continuing.

How this calculator works
What this page estimates
This Dark Store Co Tenancy Cost Calculator is built to give a quick, browser-based estimate for dark store co tenancy cost. Dark stores trigger cotenancy even while paying. This calculator sizes. 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 dark store co tenancy cost 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 dark store co tenancy cost 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
Go-dark clauses?
Anchor tenant may keep paying rent but stop operating (dark). Small shops' cotenancy clauses often trigger on dark as well as vacancy, meaning landlord loses small-shop NOI even while anchor rent continues. Specifically lethal for box stores closing stores.
Why go dark?
Chain decision to close underperforming store while lease term remains. Easier to pay rent than negotiate termination. Often signals coming bankruptcy or corporate restructuring. Co-tenancy exposure often large enough that landlord initiates negotiation.
Landlord remedies?
Negotiate continuous operations covenant upfront. Build go-dark penalty or recapture right into lease. Broker subtenants. Swap anchor for replacement (rent gap vs cotenancy cost tradeoff). Fight through estoppel or assignment denial on transfers to intent-to-dark occupiers.
