In short
Loan-to-value, usually shortened to LTV, is the share of an asset's value that you are borrowing. Divide the loan amount by the price the lender accepts, multiply by 100, and you have it. Buy a R1 500 000 home with a R150 000 deposit and you need a bond of R1 350 000, which is an LTV of 90 percent. Put down nothing and your LTV is 100 percent.
The number matters because it measures the lender's exposure rather than your budget. South African banks routinely approve 100 percent bonds for buyers with a clean credit record and stable income, but they price that extra risk into the interest rate. On a R1 350 000 bond over 20 years, half a percentage point is roughly R456 a month and about R109 000 in extra interest over the full term.
LTV runs through vehicle finance, further advances and refinancing too, and it behaves differently in each. A car loses value while the balance is still high, which is how borrowers end up owing more than the vehicle is worth. This guide explains how the ratio is calculated, what the key terms mean, how lenders actually use the number, what a deposit buys you, and the practical steps that improve your ratio before you submit an application.
Key figure
Loan-to-value is the loan amount expressed as a percentage of what the lender says the asset is worth. Borrow R900 000 against a R1 000 000 property and your LTV is 90 percent.
The arithmetic is deliberately simple. Take the amount you are borrowing, divide it by the value of the asset securing the loan, and express the answer as a percentage. A R1 350 000 bond on a R1 500 000 house is 90 percent. A R270 000 vehicle finance agreement on a R300 000 car is also 90 percent. The same formula applies whether the security is residential property, a commercial building or a bakkie.
The detail that catches buyers out is which value goes into the denominator. Lenders do not simply accept the price on the offer to purchase. They instruct their own valuation and then lend against the lower of the two figures. If you agree to pay R1 600 000 for a property the bank values at R1 500 000, the bond is calculated on R1 500 000 and the R100 000 difference has to come out of your pocket. That gap is the single most common reason an approved buyer suddenly cannot close.
Vehicle finance adds its own twist. Extras that get rolled into the agreement, such as a service plan, an extended warranty or a tracking unit, push the amount financed above the price of the car itself. The LTV can start above 100 percent on day one, before depreciation has taken a single rand off the value.
The vocabulary
LTV sits at the centre of a small cluster of terms that every bond consultant and vehicle finance manager uses as though everyone already knows them. These are the eight that change what you pay, what you can borrow and what happens if you need to sell earlier than planned.
All rand figures are illustrative and rounded. LTV thresholds, valuation policies and rate concessions are set by each credit provider individually, so two NCR-registered lenders can treat the identical deposit very differently. Ask for the specific LTV band your quote is priced on, in writing, before you accept an offer.
Risk, priced
Your LTV does not tell a lender whether you can afford the loan. It tells them what happens if you stop paying it.
Affordability is a separate test, and under the National Credit Act every registered credit provider has to run it before granting credit: income in, living expenses and existing debt out, and enough left over to carry the new instalment. LTV answers a different question entirely. If the agreement fails and the asset has to be sold, will the proceeds cover what is still owed? At 60 percent the answer is almost always yes. At 100 percent, a flat property market plus the costs of a forced sale can leave the lender short.
That is why the same applicant, with the same salary and the same credit score, can be quoted different rates on a 90 percent bond and a 100 percent bond. The difference is often a fraction of a percentage point, which sounds trivial and is not. On a R1 350 000 bond over 20 years, half a percentage point is roughly R456 a month and around R109 000 across the full term. A deposit of R150 000 can therefore repay most of itself in interest saved.
LTV also shapes the parts of a deal that never appear in the advertisement. A lower ratio strengthens your hand when you ask one bank to beat another's offer, it improves your chances of an access bond or a further advance later, and it shortens the period during which selling the property would mean writing a cheque rather than banking one.
Deposit or no deposit
A no-deposit bond is not a trap and it is not a free lunch. It is a trade between getting into the market now and paying more for the privilege. Weigh both columns against your own timeline before you decide.
What a 100 percent bond gives you
Saving a 10 percent deposit on a R1 500 000 home means putting away R150 000 in cash, which takes most households several years while rent and property prices keep moving. A 100 percent bond converts that waiting time into ownership and starts building equity immediately.
Money sunk into a deposit is difficult to get back quickly. Keeping it for transfer costs, the move itself, immediate repairs and an emergency buffer can leave you in a far stronger position than a marginally lower instalment would.
South African banks compete hard for first-time buyers with clean credit records and stable income, and a full-price bond is a standard part of that competition. Some lenders will also consider financing part of the transfer and registration costs on top.
What a 100 percent bond costs you
Lenders price the extra risk into the interest rate, and the premium runs for the entire term unless you refinance. Over 20 years the difference between a 90 percent and a 100 percent bond can comfortably exceed a hundred thousand rand.
Selling within the first few years becomes expensive. Estate agent commission alone typically runs at around 5 to 7 percent plus VAT, and with no deposit behind you there is no cushion of equity to absorb it.
The bond covers the purchase price, not transfer duty, bond registration, conveyancing fees, rates clearance or moving costs. Those are payable before the keys change hands and routinely run into tens of thousands of rand.

Remember
LTV is one of the few numbers in a credit agreement that you can still influence after you have chosen the property or the car. These six points are where that influence lives.
Divide the amount you need by the price the lender will accept, and know the figure before a consultant quotes it back to you.
Moving from 100 to 90 percent usually earns a better rate, and on a bond that saving compounds over two decades into six figures.
If the valuation lands under your offer price, you cover the gap in cash or the transaction quietly falls apart.
Vehicles lose value faster than the balance falls, so a no-deposit agreement with a balloon payment can leave you in negative equity for years.
A falling LTV is what makes a further advance, an access facility or a better refinancing deal possible three or four years from now.
Lenders price LTV risk differently, so the same deposit can buy a materially better rate at one provider than at the one across the road.
