Definition
Loan-to-cost ratio compares a loan amount to the total cost of a project rather than to the property's appraised value. Total project cost typically includes the purchase price or land value, hard construction costs, soft costs such as architecture, engineering, and permitting fees, financing costs, and a contingency reserve. LTC is the primary sizing metric for ground-up development and heavy renovation projects, where a completed appraisal of the as-stabilized property may not yet exist or may be too speculative to rely on for loan sizing. Lenders typically cap LTC at 65% to 80% of total project cost, requiring the sponsor to fund the remainder through equity, mezzanine debt, or preferred equity. LTC and loan-to-value ratio are often used together: a lender might size a construction loan to the lower of 75% LTC or 65% loan-to-as-stabilized-value, whichever produces the smaller loan amount. This dual test protects the lender both against cost overruns during construction and against a shortfall between projected and actual stabilized value once the project is complete.
How It Works
Formula
LTC = Loan Amount / Total Project Cost
A developer submits a detailed project budget covering land or acquisition cost, hard costs, soft costs, and a contingency line. The lender reviews the budget for reasonableness, often with an independent cost consultant, then applies its maximum LTC threshold to determine the loan amount. As construction proceeds, the lender disburses loan proceeds in draws tied to completed work, verified through inspections, rather than funding the full amount at closing. If actual costs exceed the original budget, the borrower is typically required to fund the overage before the lender advances additional draws, since the loan amount was fixed against the original approved budget rather than adjusting automatically with cost increases. Because the loan amount is fixed against the original approved budget rather than the borrower's actual spending, sponsors have a strong incentive to build a realistic contingency line into the budget from the start.
Example
For example, a developer plans a ground-up multifamily project with total costs of $20,000,000, including $4,000,000 in land, $14,000,000 in hard costs, and $2,000,000 in soft costs and contingency. A construction lender offers 70% LTC. Loan Amount = $20,000,000 x 0.70 = $14,000,000. The developer must fund the remaining $6,000,000 (30%) through equity or subordinate capital before or alongside the construction loan, and the lender disburses the $14,000,000 in monthly draws as construction milestones are completed and verified. This example illustrates why sponsors typically line up committed equity before finalizing a construction budget with their lender.
Why It Matters
LTC determines how much equity a developer needs to raise before breaking ground, directly shaping project feasibility and sponsor returns. Because LTC is based on a fixed, itemized budget rather than a future appraisal, it forces discipline in cost estimating and protects both borrower and lender from underfunding a project midway through construction. Sponsors who understand LTC can better anticipate their equity requirement early in underwriting, rather than being surprised late in the process when a lender's cost review reduces the available loan proceeds below what was originally assumed.
In depth
LTC Versus LTV: When Each One Binds
LTC and LTV answer different questions and apply at different points in a project's life. LTC compares the loan to what the sponsor is actually spending to acquire and complete the project, making it the primary sizing tool for construction and heavy value-add deals where a stabilized appraisal does not yet exist or is largely speculative.
LTV compares the loan to appraised value, which becomes more reliable once a project nears stabilization and comparable sales data supports a defensible number. Many construction loans are sized to the lower of a maximum LTC and a maximum LTV based on projected stabilized value, so a project with unusually low costs relative to its expected value can still be capped by the LTV test.
Phased developments complicate this comparison further, since a sponsor building a project in multiple phases may seek LTC financing on an early phase using land value allocated across the entire site, requiring the lender to carefully define what portion of total site cost belongs to the phase actually being financed.
What Counts as Total Project Cost
Lenders scrutinize exactly what belongs in the cost basis used for the LTC calculation.
Because the LTC calculation depends entirely on this cost basis, disputes over what belongs in it are common during underwriting, particularly around whether a developer fee should be included.
Lenders also distinguish between costs the sponsor has already incurred, sometimes credited toward the required equity contribution if properly documented, and costs still to be spent, which is why a sponsor who purchased land years earlier at a much lower basis than current market value often needs to negotiate how that gain factors into the LTC calculation.
- Included: land or acquisition price, hard construction costs, soft costs such as architecture and permitting, interest reserve, and a contingency line
- Included: developer fee, if the lender's guidelines permit capitalizing it into cost basis
- Typically excluded: deferred developer profit not yet earned, and costs incurred before the lender's engagement that lack documentation
- Often capped: contingency lines above roughly 5% to 10% of hard costs may be excluded from the cost basis entirely
Worked Scenario: Cost Overruns After Closing
For example, a developer closes a construction loan sized at 65% LTC against a $15,000,000 total budget, producing a $9,750,000 loan commitment. Midway through construction, unforeseen site conditions add $1,200,000 to hard costs, bringing the revised total budget to $16,200,000.
Because the loan amount was fixed at closing rather than tied to a moving cost basis, the developer must fund the entire $1,200,000 overrun out of additional equity or a mezzanine loan to keep the project on track, since the LTC ratio used to size the original loan does not automatically adjust upward with the budget.
Lenders reviewing a request for additional proceeds tied to a cost overrun typically re-examine the entire project budget rather than simply approving the incremental amount, since a first overrun can be an early signal of further cost pressure elsewhere in the project, particularly on a fixed-price contract that has already required one change order.
Documentation Lenders Require to Verify Cost
To confirm the cost basis behind an LTC calculation, lenders typically request a fully itemized construction budget (the schedule of values), signed contracts with the general contractor and major subcontractors, a title report showing the acquisition price, and, on larger deals, an independent third-party cost consultant's review of the budget for reasonableness.
During construction, ongoing draws are verified against this same budget, with the lender or its inspector confirming completed work matches the amount requested in each draw before releasing funds, tying the LTC ratio to real, verified spending throughout the project.
Change orders during construction are tracked against the original schedule of values line by line, and a pattern of frequent or large change orders can prompt the lender to require a more detailed explanation, or in some cases an updated independent cost review, before continuing to fund draws at the originally approved pace.
Negotiating LTC in a Term Sheet
Sponsors can often negotiate which cost items the lender includes in the basis, since a broader definition of eligible costs produces a larger loan at the same LTC percentage. Including a market-rate developer fee, or capitalizing a larger interest reserve into the cost basis, are both common negotiation points worth raising before signing a term sheet.
It also helps to clarify upfront how the lender will treat cost overruns: whether the loan can be increased through additional future funding if overruns are modest and well documented, or whether any overrun must be funded entirely with new equity regardless of cause.
Sponsors should also clarify at term sheet stage whether the lender's maximum LTC applies to the entire project cost or only to costs incurred after the loan closes, since land or acquisition costs paid well before the loan application can sometimes be treated differently in the final calculation.

Frequently Asked Questions
What is a typical maximum LTC for construction loans?
Construction and heavy value-add loans typically cap LTC between 65% and 80%, depending on the lender, property type, sponsor experience, and market conditions. Ground-up development on unproven locations tends to sit at the lower end of that range. Riskier property types and unproven markets generally sit at the lower end of that range.
What is the difference between LTC and LTV?
LTC compares the loan to total project cost, which is fixed and known upfront. LTV compares the loan to appraised value, which depends on projected income and market cap rates once the project is complete. Lenders often size to whichever produces the smaller loan.
What costs are included in total project cost for LTC?
Total project cost usually includes land or acquisition price, hard construction costs, soft costs like design and permitting fees, financing costs such as interest reserve and loan fees, and a contingency reserve for unexpected overruns. Some lenders also include a portion of pre-development costs such as architectural drawings incurred before the loan closes.
