The direct answer
Loan-to-cost (LTC) compares a loan with total project cost, while loan-to-value (LTV) compares a loan with a property value. In commercial real estate they answer different leverage questions, so the same deal can show materially different LTC and LTV ratios.
Use the correct denominator
LTC commonly uses eligible acquisition, construction and other project costs in the denominator. LTV uses the value recognized for the financing analysis. A higher completed value can therefore produce a lower LTV even when LTC remains high.

Match the ratio to the project stage
LTC is especially useful for development, renovation and value-add projects because cost is observable during the business plan. LTV is more directly tied to collateral value, which can be current, as-is, stabilized or another lender-defined value depending on the transaction.
Do not treat either ratio as an approval rule
Lenders also consider debt service, debt yield, sponsor strength, reserves, market conditions and property-specific risk. Verify the lender’s definitions of eligible cost and value before comparing thresholds.
Worked example
A project with $8 million of total cost, a $6 million loan and an expected stabilized value of $10 million has 75% LTC and 60% LTV. The same loan produces different ratios because the denominators answer different questions.

Common mistakes and limitations
Do not substitute projected value for project cost when calculating LTC, or assume a lender will accept the borrower’s value estimate for LTV.
Does not calculate commercial loan terms, taxes or future sale value unless supplied in an optional scenario mode.
Frequently asked questions
Can LTC be higher than LTV?
Yes. If stabilized value exceeds total project cost, the same loan can produce a higher LTC than LTV.
Which ratio matters more to a commercial lender?
It depends on the loan type and stage; lenders often review both along with coverage, debt yield and other underwriting factors.
