LTC calculator for CRE construction lending

An LTC calculator divides credit extended by the total cost of a property including construction costs at origination, and expresses the result as a percent. The OCC CRE handbook treats loan-to-cost as a companion equity test alongside loan-to-value, stating that prudent policies typically establish loan limits as a maximum percentage of cost as well as of market value so that the borrower contributes sufficient equity. Where the asset is still being built, cost is observable from the budget and land basis; market value remains prospective. The European Systemic Risk Board recommends that for income-producing CRE property under development, national macroprudential authorities may monitor LTC instead of LTV at origination.

LTC calculator formula

LTC = extension of credit / (total property cost + all construction costs) x 100

ESRB materials define LTC as the initial amount of all loans granted relative to the costs associated with construction of the property until completion. Desks decide whether the numerator is the subject facility only or all loans funding the project, and disclose that choice beside the result.

Inputs

• Facility commitment (and other loans included in the LTC numerator)
• Land basis included in the approved cost budget
• Hard costs: labour, materials and contractor amounts
• Soft costs: architecture, engineering, permits and other approved soft items
• Interest reserve and financed fees if counted inside total cost under the credit policy
• Sponsor equity already injected or required before draws
• Contingency line in the budget, if treated as part of total cost

The OCC CRE handbook lists acceptable forms of borrower equity in a construction loan as cash, unencumbered readily marketable assets, paid development expenses and contributed real property. Loan policies are expected to state the acceptable types and sources of equity and the timing of the contribution. Interest reserves are treated as a construction cost element that should be properly estimated and budgeted, not as a form of equity, and the handbook cautions that a capitalised interest reserve can mask a borrower's actual repayment capacity.

Worked numerical example

Illustrative construction loan budget:

• Land (cash basis): 20.0 million
• Hard costs: 55.0 million
• Soft costs: 8.0 million
• Interest reserve and financed fees in budget: 5.0 million
• Contingency: 4.0 million
• Total cost = 92.0 million

• Senior construction facility: 64.4 million
• Other project loans in numerator: none

LTC = 64.4 / 92.0 x 100 = 70.0%

Implied equity in the cost stack = 92.0 - 64.4 = 27.6 million, or 30.0% of total cost. If a second facility of 9.2 million is added to the numerator, total loans = 73.6 million and LTC = 80.0%. The calculator result changes solely because the debt stack in the numerator changed; the budget did not.

ESRB Occasional Paper No 29 records a Danish supervisory example, under which the Danish Financial Supervisory Authority guidelines set a maximum LTC of 65 percent for CRE development projects, assessed jointly with LTV, DSCR, interest coverage and leverage measures, so that a weaker reading on one measure can be offset by a stronger reading on another. That national figure is an example of supervisory hardening in one jurisdiction, not a universal ceiling applied by every desk.

Interpretation limits

LTC measures what was spent against credit extended. LTV measures collateral value against credit extended. A project can pass an LTC test and still fail an as-stabilised LTV, debt yield or DSCR test if costs approach or exceed the value that projected income supports. OCC guidance frames expected costs and the value supported by projected net operating income as measures considered together rather than in isolation.

The ratio is sensitive to how the cost base is built. A total cost figure inflated with unsupported soft items produces a lower reported LTC without any corresponding increase in real equity. A cost base that omits interest reserves the facility itself capitalises understates total cost. A sponsor guarantee recorded as cash equity overstates the equity cushion actually funded into the project. Each of these is a variation on the same underlying issue: the LTC ratio only reflects the inputs entered into it.

LTC binds most tightly while a project generates little or no operating cash flow, since there is no income stream yet to test independently. Take-out capacity after completion still depends on projected coverage and leverage once the asset is stabilised, which is why LTC functions as an origination-stage construction measure rather than a substitute for post-completion cash-flow tests.
