Tenant Default Exposure Calculator

Single-tenant default on large commercial leases creates binary property risk.

Annual rent

Remaining lease months

Re-tenanting downtime

Market rent at re-lease

LC + TI cost

Total default exposure

$2,950,000

Downtime lost rent

$1,500,000

Market rent delta loss

$600,000

How the math works

Downtime = monthly × downtime. Market delta = (old − new) × remaining months. Total = both + LC/TI.

$125k × 12 = $1.5M downtime + $12.5k × 48 = $600k delta + $850k LC/TI = $2.95M exposure.

How this calculator works

What this page estimates

This Tenant Default Exposure Calculator is built to give a quick, browser-based estimate for tenant default exposure. Single-tenant default on large commercial leases creates binary property risk. 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 tenant default exposure 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 tenant default exposure 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 tenant default exposure?

The total economic impact from a tenant ceasing rent payments, including: lost rent through remainder of lease (net of re-leasing capture), downtime to find replacement tenant, market rent delta if re-leased at different rate, LC (leasing commission), TI (tenant improvement allowance), legal costs to pursue guarantor if applicable. Commercial single-tenant: 20-40% of lease value. Multi-tenant 10%+ single tenant: 5-15% of total. Institutional underwriting requires default-exposure analysis.

Probability of tenant default?

Commercial tenant bankruptcy rate: 1-3% per year in healthy economy, 4-8% in recession. Sector dependencies: retail tenants (apparel, bookstores, movie theaters) historically 5-10%; medical office lowest 0.5-1.5%; industrial mid-range 2-4%. Credit ratings help: AA/A tenant bankruptcy rate <0.5%; unrated / private <$100M revenue: 3-8%. Always request tenant credit info before leasing; track ongoing via D&B.

How to mitigate?

Personal/parent guarantee from creditworthy guarantor. Security deposit (6-12 months rent for weak credit; 1-3 for investment grade). Letter of credit. Rent coverage ratio covenants (tenant maintains 1.25-1.5x EBITDA/rent). Early termination fees (tenant pays 6-12 months rent to walk). SNDA (subordination, non-disturbance) with lender. Different tenants call for different mitigation stacks; don't use one-size-fits-all.

What if tenant files bankruptcy?

Automatic stay halts collection. Tenant can assume, assume and assign (transfer to buyer of business), or reject the lease. If rejected, landlord gets unsecured claim for remaining rent. Recovery rates on unsecured claims: 3-15%. Institutional landlords typically write off 80-95% of remaining lease value. Strong lease terms (guaranty, security deposit) can help but often not enough. Workout vs litigation: workout preferred — contested cases drag 2-5 years.
