Loan to Cost Ratio (LTC)

How to Calculate Loan to Cost Ratio (LTC)

From the perspective of lenders underwriting a loan, the loan to cost (LTC) measures the riskiness of a requested loan by comparing the total loan amount to the total cost of the project.

  • Total Loan → The total size of the loan provided by the lender to financing the real estate project.
  • Total Project Cost → The cost component depends on the context of the project. For instance, the cost in a development project is likely to be the construction costs, or the purchase price in acquisition projects.

The loan to cost (LTC) is often used in conjunction with the loan to value ratio (LTV) and the debt service coverage (DSCR) ratio to determine the risk profile of a potential borrower.

The real estate lender’s decision on the loan request, the sizing of the loan, and the financing terms, such as interest rate pricing, are predicated on the borrower’s credit risk.

Each ratio is a measure of risk to gauge the likelihood of the borrower defaulting on the loan.

But unique to the loan to cost ratio (LTC), the metric is perceived as more conservative, which appeals to real estate lenders that prioritize capital preservation over yield.

The LTC ratio is a tool for lenders to gauge the risk posed by a requested loan to fund a project, whereas real estate investors use the ratio to determine their required equity contribution to complete the project.

Loan to Cost Ratio Formula (LTC)

The loan to cost ratio (LTC) formula divides the total loan amount by the total development cost of the real estate project.

Loan to Cost Ratio (LTC) = Total Loan ÷ Total Development Cost

Since the LTC ratio is expressed as a percentage, the resulting figure must then be multiplied by 100.

The “Total Development Cost” includes the following cost categories:

  • Hard Costs → Construction Materials and Labor Costs, Site Work Activities, Utilities Set-Up (HVAC), Landscaping, Parking Lot and Paving Costs
  • Soft Costs → Architectural Design, Engineering Planning, Inspection and Permit Fees, Professional Services (Legal, Accounting Fees), Maintenance and Insurance Costs
  • Property Acquisition Costs → Land Acquisition, Property Purchase Price
  • Operating Expenses → General and Administrative (G&A), Security Fees, Property Management Fees, Payroll, Marketing, Advertising

In comparison, the loan to value ratio (LTV) divides the total loan amount by the property’s fair value. The property value is based on an appraisal of its current fair market value (FMV).

Loan to Value Ratio (LTV) = Total Loan ÷ Property Value

What is a Good Loan to Cost Ratio?

The maximum loan to cost ratio (LTC) requirement is specific to a given lender and can be affected by external factors, such as the current interest rate environment, the supply/demand conditions in the real estate market, and economic outlook.

Generally, the maximum loan to cost ratio (LTC) requirement set by lenders in the commercial real estate market (CRE) is between 80% to 90%.

Therefore, borrowers must fulfill a 10% to 20% down payment – i.e. equity contribution – as part of the financing agreement.

Most institutional real estate lenders also set a constraint on the maximum LTV ratio, which tends to be around 70% to 80%. The lower LTV ratio requirement range reaffirms the notion that lenders in pursuit of higher yields prefer to utilize the LTV ratio in their underwriting analysis more than risk-averse, conservative lenders.

A higher loan to cost ratio (LTC) implies greater risk because the borrower has contributed less equity in the total financing of the project (and vice versa for lower ratios).

The lower the borrower’s equity contribution (i.e. less “skin in the game”), the higher the likelihood that the lender will not approve the financing because of the disproportionate allocation of risk placed on the lender.

Loan to Cost (LTC) vs. Loan to Value Ratio (LTV): What is the Difference?

In the real estate underwriting process, the loan to cost (LTC) and loan to value (LTV) are complementary financial ratios that each provide practical insights around debt sizing.

With that said, real estate financing arrangements where the loan to cost ratio (LTC) is the main determinant of the loan size and terms are perceived to be more lenient (and favorable) to the borrower.

However, the LTC ratio is also viewed as riskier transactions to the lender because of the increased reliance on leverage.

The decision to use the loan to cost ratio (LTC) or loan to value ratio (LTV) in the underwriting process is not mutually exclusive. But rather, the two ratios can each be used to set parameters on the loan sizing based on the estimated risk tied to the project.

1. Commercial Real Estate Property Assumptions (CRE)

Suppose a commercial mortgage lender is performing diligence as part of the underwriting process on a real estate developer’s request for a loan to fund a long-term construction project.

The total property acquisition cost – inclusive of the land purchase price and transaction closing fees – is estimated to be $2 million.

The other components of the development cost are as follows.

The sum of the four costs amounts to $27 million, which represents the total development costs of the construction project.

Since we’ve determined the total capital required ($27 million), the next step is to make an assumption for our lender’s maximum loan to cost ratio (LTC), which we’ll set at 80%.

After multiplying the total development costs by the maximum LTC ratio, the maximum loan amount is implied to be $21.6 million.

Note: The total development costs neglect financing costs, such as the upfront loan origination fee, so our total development cost figure is on an unlevered basis.

2. Loan to Cost Ratio Calculation Example (LTC)

In the next section, we’ll start by confirming the loan to cost ratio (%) is in fact 80%.

Upon inputting our total loan and total development costs into the loan to cost ratio formula, we arrive at an LTC ratio of 80%.

The $21.6 million is the maximum loan size, at which the lender can maintain an LTC ratio below 80%.

From there, we’ll subtract our loan to cost ratio (LTC) of 80% from one to determine the required equity contribution in percentage form.

The 20% equity interest is then multiplied by the total development costs to quantify the equity contribution from the real estate developer in dollar terms, which comes out to $5.4 million.
