What it means
Loan to value, usually written as LTV, sits at the heart of almost every secured lending decision. It compares the size of the loan with the appraised or market value of the asset pledged as security, whether that asset is a house, a warehouse, a fleet of vehicles or a piece of manufacturing equipment.
The ratio matters because it determines the lender's margin of safety. If a borrower stops paying and the asset is sold for less than expected, a low LTV means the sale proceeds still cover the debt, while a high LTV means the lender takes a loss.
For borrowers, LTV drives both access to credit and its price. Loans at 60% LTV typically attract the best interest rates, loans above 80% often require mortgage insurance or personal guarantees, and loans above 90% may simply be declined by mainstream lenders.
The ratio moves after the loan is made, which is the part people forget. Repayments push the loan balance down and rising asset values push the denominator up, so LTV usually improves over time, but a falling market can push it the other way and leave a borrower owing more than the asset is worth.
Commercial lenders often combine LTV with a debt service test, because a low LTV on an asset that generates no income is still a poor credit. Business borrowers should also note that lenders value assets conservatively, so the LTV in a loan offer is rarely calculated on the price the borrower thinks the asset would fetch.
In practice
Real-world examples.
Example
A dental practice buys a $600,000 surgery building with a $150,000 deposit and a $450,000 loan, giving a 75% LTV. The lender offers a lower margin than it would at 85%, saving the practice several thousand dollars of interest a year.
Example
A haulage firm finances three trucks worth $240,000 in total with a $216,000 asset finance facility, an LTV of 90%. Because trucks lose value quickly, the lender insists on a five-year term so that the loan balance falls faster than the resale value.
Example
A property investor watches local values slip by 15% and finds that a portfolio bought at 80% LTV is now closer to 94%. The lender declines further drawdowns until the investor injects cash or sells one unit to bring the ratio back down.
Think of it
“LTV shows how much of the property is borrowed versus owned-your leverage.
Formula
Calculation
Loan to Value Ratio = (Loan Amount / Appraised Value of Asset) x 100
A logistics company buys a distribution unit valued by the lender's surveyor at $450,000 and puts down $90,000 of its own cash, borrowing the remaining $360,000. Dividing $360,000 by $450,000 gives 0.80, which is 80% when multiplied by 100.
Five years later the company has repaid $60,000 of principal, leaving a balance of $300,000, and the unit has been revalued at $500,000. The new calculation is $300,000 divided by $500,000, which equals 0.60, so the LTV has fallen to 60% and the borrower is likely to qualify for a cheaper refinancing deal.Case study
Seen in the real world.
Meadowgate Bakery is an invented company used here as an illustrative example. It bought a production unit for $800,000 with a $640,000 loan, an LTV of 80%, at a point when the local industrial market was busy and valuations were generous.
Two years later the bakery wanted to borrow another $120,000 for a second oven line. The unit had been revalued at $760,000 and the outstanding loan was $610,000, so the existing LTV stood at just over 80% and the requested top-up would have taken it to roughly 96%.
In this illustrative case the lender declined the top-up secured on the building and instead offered equipment finance secured on the oven itself at 70% of its cost. The owners contributed the balance from retained profits, which kept the property loan untouched and gave the business a second, separately secured facility.
Watch out
Common mistakes.
- Using the purchase price rather than the lender's own valuation, which is often lower and is the figure that actually drives the offer.
- Treating LTV as fixed at completion, when both the loan balance and the asset value change every year.
- Ignoring the fees, stamp duties and legal costs that are not covered by the loan and must come from the borrower's own cash.
Questions
People also ask.
What counts as a good loan to value ratio?
Anything at or below 70% is generally seen as conservative, while 80% is a common mainstream limit and above 90% is treated as high risk.
Does a high LTV always mean a higher interest rate?
Usually yes, because the lender is taking more risk, and the extra cost may come as a higher margin, an insurance premium or a stricter set of covenants.
What happens if the asset value falls below the loan balance?
The borrower is in negative equity, and while payments can continue as normal, refinancing or selling becomes difficult until the gap closes.
