In short
Loan-to-value is the simplest number in a credit agreement and one of the most expensive to misread. It is the amount you are borrowing divided by the value the lender puts on the asset, written as a percentage: borrow R800 000 against a home the bank values at R1 000 000 and your LTV is 80 percent. What the figure measures is not whether you can afford the instalment. The National Credit Act obliges every registered credit provider to test affordability separately. LTV answers a colder question: if the agreement fails and the asset has to be sold, does the sale cover what is still owed?
In South Africa that single percentage decides three things at once. It shapes whether the application is approved, how much cash you have to put on the table, and what margin the bank adds to your interest rate. Most lenders are comfortable at 80 percent or below, lend routinely to 90 percent, and will still write a 100 percent bond for a first-time buyer with a clean credit record, but every step up the ladder is priced. Vehicle finance uses the same formula and behaves quite differently, because a car loses value faster than the balance falls. This guide covers the bands lenders work to, what pushes your ratio up without you noticing, eight practical ways to bring it down, and how LTV is reassessed when you refinance.
The bands
The four loan-to-value bands South African lenders price against.
Comfort zone
Under 80%
A deposit of a fifth or more. Approval is straightforward for a clean record, and this is the band where rate concessions are easiest to negotiate.
Standard band
80-90%
The everyday range for South African bonds and vehicle finance. Expect approval on a solid profile, with a slightly firmer margin than the band below.
Full finance
90-100%
No deposit, or close to it. Widely granted to first-time buyers, but the credit assessment is stricter and the rate carries a visible premium.
Underwater
Over 100%
You owe more than the asset is worth. Common on vehicles financed with extras and a balloon, and it blocks a sale until the gap is paid in cash.
These bands are conventions rather than published rules. No South African bank advertises an LTV cut-off, and two NCR-licensed lenders can treat the identical deposit differently on the same day, because each one weighs income stability, credit record and the type of property in its own way. What stays consistent is the direction of travel: the less of the purchase price you are borrowing, the less the lender stands to lose, and the more room there is to price the deal in your favour.
The money involved is not marginal. On a bond of R1 350 000 over 20 years, half a percentage point of margin is roughly R460 a month, which comes to something close to R110 000 across the full term. That is the arithmetic that turns a deposit from a hurdle into an investment. Ask any lender to tell you, in writing, which LTV band your quote has been priced on. If a slightly larger deposit would move you into the next band down, it is worth knowing before you sign rather than after.
The calculation
The formula is deliberately plain. Divide the amount you are borrowing by the value of the asset securing the loan, then multiply by 100. A bond of R1 350 000 on a R1 500 000 house is 90 percent. Vehicle finance of R270 000 on a R300 000 car is also 90 percent. The same sum applies whether the security is a sectional title flat, a smallholding or a bakkie, which is why the term travels across every part of secured lending in South Africa.
The detail that catches buyers out sits in the denominator. Lenders do not simply accept the figure on the offer to purchase. They instruct their own valuation and then lend against the lower of the two numbers. Agree to pay R1 600 000 for a property the bank values at R1 500 000 and the bond is calculated on R1 500 000, leaving a R100 000 shortfall you have to find in cash. A valuation that comes in under the price is one of the most common reasons an approved buyer suddenly cannot close, and it is worth asking the bank what its valuer arrived at rather than assuming the offer price stands.
Three things routinely push a ratio higher than the buyer expected. The first is a low valuation, as above. The second is the extras that get rolled into a vehicle finance agreement, such as a service plan, an extended warranty, a tracking unit or dealer delivery fees, which lift the amount financed above the price of the car itself and can put you over 100 percent before you have driven anywhere. The third is a balloon payment, which cuts the monthly instalment by deferring a lump sum to the end of the term and, in doing so, keeps the outstanding balance high for years.
It is also worth separating LTV from affordability in your own head, because lenders certainly do. Affordability is the National Credit Act test: income in, tax, debt instalments and living costs out, and enough left over to carry the new repayment. LTV is a security test. A high earner with no deposit and a first-time buyer with 20 percent saved can walk out of the same branch with very different offers, and the difference will show up in the margin rather than the headline approval.
Practical steps
LTV is one of the few numbers in a credit application you can still influence after choosing the property or the car. Some of these steps take months and some take a single phone call, but each one moves the ratio in the direction that lenders reward. Work through them before you submit an application rather than after the first offer arrives.
The most direct lever there is, and the bank statements behind it work in your favour too.
Every rand you contribute upfront cuts the amount financed rand for rand. Regular monthly transfers into a savings account also demonstrate saving discipline that no credit score can show, which reads far better to an assessor than a single large deposit that appears from nowhere in the month you apply.
You cannot manage a ratio when you only know half of the sum it is built on.
The bond is calculated on the lower of the valuation and the purchase price, so the valuation figure is half of your LTV. Ask for it in writing as soon as it is available. If it lands under your offer, you have a decision to make while you still have room to make it.
A shortfall between price and valuation is a negotiating point, not automatically your problem.
A seller who has already had one buyer stall on a low valuation knows the next bank is likely to arrive at a similar number. Take the valuation back to the estate agent and ask for the price to be adjusted. Walking away is cheaper than covering a six-figure gap in cash.
Service plans, warranties and tracking units financed with the car inflate the ratio from day one.
Anything rolled into the finance agreement is borrowed money that the car itself does not secure. Pay for the service plan and the tracker separately where you can afford to, or negotiate them out of the deal entirely. It keeps the amount financed close to the actual value of the vehicle.
A lower instalment now is paid for with a high outstanding balance for the whole term.
A balloon defers a large lump sum to the end of the agreement, so the capital falls slowly while the car keeps depreciating. That combination is the most reliable way into negative equity. If the instalment only works with a balloon, the honest conclusion is usually that the vehicle is too expensive.
Stretching the term lowers the instalment but leaves your ratio almost exactly where it was.
A 72-month vehicle agreement instead of 54 months makes the monthly figure look manageable while the balance stays high for years longer. Buying a car or a home priced R100 000 lower reduces what you borrow immediately, improves the ratio and shortens the period in which selling would cost you money.
Additional capital paid early is when it does the most work on both interest and ratio.
Interest is charged on the outstanding balance, so an extra payment in year two removes far more total interest than the same amount in year fifteen. It also pulls the balance down ahead of schedule, which is what builds the equity you will need for a further advance or a refinance later.
Refinancing resets the ratio using today's value and today's balance, not the original ones.
When you switch or refinance, the new lender values the asset again and measures it against what you still owe. Years of capital repayments and any appreciation in the property both work for you here. Come in at a lower band than you started on and the rate conversation begins from a much stronger position.
Cars are not houses
A home and a car use the same formula and then move in opposite directions. Property in most South African areas holds its value or grows slowly, so a bond that starts at 90 percent drifts downwards year after year as capital is repaid. A vehicle starts losing value the moment it leaves the dealership, often around a fifth in the first year and a further chunk in the second, while the finance balance falls slowly because the early instalments are weighted towards interest.
The result is familiar to anyone who has tried to sell a financed car early. Take R300 000 of vehicle finance with no deposit over 72 months. After two years the balance is still somewhere near R225 000, while the car may be worth closer to R205 000 on a trade-in. That gap has to be settled in cash before the vehicle can change hands, and it is the reason a settlement quote so often comes as an unwelcome surprise. Add a balloon payment and the gap opens wider and stays open for longer.
None of this makes vehicle finance a bad instrument. It makes the deposit and the term the two decisions worth agonising over. A deposit of 10 to 20 percent, a term you can genuinely afford rather than the longest one offered, and no balloon will usually keep you on the right side of the line within the first eighteen months. Comprehensive insurance is compulsory on financed vehicles, and it is worth understanding whether your cover pays out market value or retail value, because that difference is exactly what a write-off exposes.

Questions and answers
The practical points borrowers most often want settled before they commit to a deposit, a price or a term.
Anything at 80 percent or below puts you in the band lenders are most comfortable with, and it is where rate concessions are easiest to ask for. Between 80 and 90 percent is entirely normal and approved every day. Above 90 percent the assessment tightens and the margin widens. There is no official cut-off, though, because each NCR-licensed lender sets its own appetite.
Yes. South African banks compete hard for first-time buyers and full-price bonds are a standard part of that competition, provided your credit record is clean and your income is stable. The trade is a firmer interest rate for the full term. Remember that the bond covers the purchase price only, so transfer duty, bond registration and conveyancing still have to be paid in cash.
The bond is calculated on the lower figure, so the difference becomes a shortfall you must cover yourself on top of any deposit. You have three realistic options: renegotiate the price with the seller, find the extra cash, or walk away. Ask for the valuation figure as soon as it exists rather than waiting for the final grant letter.
It usually does, and the effect compounds. On a bond of R1 350 000 over 20 years, half a percentage point is roughly R460 a month and close to R110 000 over the full term. That is why a deposit can repay most of itself in interest saved. Ask each lender which band it has priced your quote on so you are comparing like with like.
It means your LTV has gone above 100 percent: the settlement balance is higher than what the vehicle would fetch. It happens most often when there was no deposit, extras were financed with the car, or a balloon payment is holding the balance up. You can still drive the car normally, but you cannot sell or trade it without paying the difference in cash.
The new lender values the asset at today's price and measures it against your current outstanding balance, so the ratio is calculated fresh. Capital you have repaid and any growth in the property's value both push it down. Falling into a lower band is often the single biggest reason a refinance produces a better rate than the original agreement did.
No, and lenders run them as two separate tests. Affordability is required by the National Credit Act and asks whether your income can carry the instalment once tax, existing debt and living costs are deducted. LTV asks what the lender recovers if the agreement fails. You can pass one and struggle with the other, which is why a strong salary with no deposit still attracts a higher margin.
