Loan-to-Value Ratio (LTV)

Loan-to-value ratio (LTV) is the ratio of a loan amount to the appraised value of the collateral securing it, expressed as a percentage. If a commercial property appraises at $1,000,000 and the lender offers a $750,000 loan, the LTV is 75%. It is one of the most fundamental metrics in commercial lending, used by lenders to quantify their exposure relative to the recoverable value of the underlying asset.

In commercial financing, LTV applies broadly across asset classes: real estate, equipment, inventory, and business acquisitions. The calculation is straightforward (loan amount divided by appraised value times 100), but the inputs can be nuanced. Lenders may use different valuation methods depending on the asset type, including fair market value, orderly liquidation value, or forced liquidation value, each of which produces a different LTV for the same loan amount.

LTV is distinct from loan-to-cost (LTC), which compares the loan amount to the total project cost rather than the appraised value. In construction and renovation financing, both ratios are evaluated, but LTV anchors to what the asset is worth upon completion, while LTC anchors to what the borrower is spending to build or improve it.

LTV directly determines how much financing a business can access against a given asset. A lower LTV means the borrower must contribute more equity (the gap between the loan and the asset value), while a higher LTV means less cash out of pocket but more lender risk. Most commercial lenders cap LTV based on asset type and loan program, so understanding where those ceilings sit is essential for structuring a capital request.

For business owners, LTV affects more than just the loan amount. Higher LTV loans typically carry higher interest rates, stricter covenants, and may require additional credit enhancements such as personal guarantees, additional collateral, or SBA backing. Conversely, borrowers who can demonstrate lower LTV through larger equity contributions often negotiate better terms, lower rates, and fewer restrictions.

Typical commercial LTV maximums vary by asset and program: conventional Commercial Real Estate loans generally cap at LTV, SBA 504 loans allow up to LTV on eligible real estate, equipment financing ranges from LTV depending on asset type and useful life, and business acquisition loans typically require LTV with goodwill often excluded from the collateral base. These thresholds shift with market conditions, asset quality, and borrower strength.

Confusing appraised value with purchase price. Lenders calculate LTV using their own appraisal, not the agreed transaction price. If a borrower pays $1.2 million for a property that appraises at $1 million, the lender uses $1 million as the denominator. The borrower must cover the $200,000 gap plus their equity contribution, which catches many first-time commercial borrowers off guard.

Ignoring which valuation method the lender uses. Fair market value, orderly liquidation value, and forced liquidation value can differ by on the same asset. Equipment lenders frequently use orderly liquidation value rather than replacement cost, which means the effective LTV ceiling is much lower than borrowers expect when they calculate based on what they paid for the equipment.

Assuming LTV is the only constraint. Even if a property supports 75% LTV, the loan may be sized lower based on debt service coverage ratio (DSCR) or debt yield requirements. Lenders use the most conservative constraint, so a property with strong equity but weak cash flow will still receive a smaller loan than the LTV alone would suggest.

Overlooking LTV changes over time. LTV is not static. As the borrower pays down principal, LTV decreases. But if asset values decline (market downturn, depreciation, deferred maintenance), LTV can increase, potentially triggering covenant violations or margin calls on certain loan structures. Balloon payment loans are particularly exposed to this risk at maturity.
