Free LVR Calculator for New Zealanders
Your loan-to-value ratio (LVR) is the size of your loan as a percentage of the property value. NZ banks use it to decide whether to lend and at what rate. Compare yours against the current Reserve Bank thresholds.
Your loan and property
Based on a $640,000 loan against a $800,000 property as an owner-occupier.
About our LVR Calculator
An NZ bank’s first lending question is "what proportion of this property are you actually buying?" The LVRLVRLoan-to-Value Ratio; loan as a percentage of property value. RBNZ caps it at 80% for owner-occupiers.View in glossary → answers it in one number. A $580,000 loan on a $720,000 home is 80.6% LVR. Anything at 80% or below is standard owner-occupier lending; anything above triggers either a low-equity margin on the rate or, at some banks, a one-off premium at drawdown.
The Reserve Bank’s LVR speed limits cap how much above-80% lending each bank can write. For owner-occupiers, no more than 20% of new monthly lending sits above 80% LVR. For investors, the line is 70% with only 5% headroom. New-build lending has its own exemption.
The calculator runs the basic LVR maths and tells you which RBNZ band you fall into. Move the property-value and loan sliders to see how repayments, an extra deposit chunk, or a price renegotiation each shifts the LVR.
How to use it
Enter the property value (purchase price or current valuation) and the loan amount you intend to take.
Toggle between owner-occupier and investor to see how each cap applies. The result panel shows your LVR, the size of your deposit or equity, and the RBNZ classification (standard, low-equity, very high, or above the cap).
For an existing home loan, the same maths runs in reverse. Enter the current property value and the remaining loan balance to see your LVR today, which determines whether you can drop a low-equity margin at refix or unlock equity for a top-up.
Why use it
LVR is the gate that decides whether a bank will even quote you. It also sets the rate add-on you pay if you sit above the threshold. A buyer at 79.5% LVR pays the standard rate on the standard schedule. A buyer at 80.5% LVR on the same loan size could pay 0.25% to 1.5% more for as long as the LVR stays above 80%, which on a $580,000 loan adds up fast.
For first-home buyers, the calculator surfaces the gap between where you are and where the rate breaks change. Adding $4,000 to a deposit to drop from 80.5% to 80.0% is sometimes worth a year of the low-equity margin, sometimes not, depending on how quickly normal repayments would have got you there anyway.
For existing borrowers, LVR is the unlock for top-up borrowing. Banks will typically lend you the difference between your current loan and 80% of the current property value, which is how renovations, second properties, and bridging finance get funded.
The maths behind it
LVR = Loan ÷ Property Value × 100 A $580,000 loan against a $720,000 property gives an LVR of 580 ÷ 720 = 80.6%. The deposit (or accumulated equity) is the other side of the same calculation: $720,000 − $580,000 = $140,000 of equity, which is 19.4% of property value. The Reserve Bank’s LVR speed limits act on the loan side: banks can only write a small share of new lending above the cap, which is why the standard owner-occupier line sits at 80% LVR.
Worked example
Sione and Mere, Christchurch first-home buyers, on a $720,000 three-bedroom unit.
Sione and Mere have saved a $140,000 deposit (a mix of personal savings and a KiwiSaver First Home Withdrawal). They are buying a $720,000 unit in Christchurch as owner-occupiers.
Loan size is $720,000 − $140,000 = $580,000. LVR is $580,000 ÷ $720,000 = 80.6%, just over the standard 80% threshold.
A loan above 80% LVR triggers the bank’s low-equity margin (typically 0.25% to 1.5% on top of the contract rate, depending on the bank). On a $580,000 loan that adds roughly $1,450 to $8,700 of extra interest a year.
If they topped the deposit up by another $4,000 to $144,000, the LVR drops to 80.0% and the low-equity margin disappears. That is the typical "next $4k saves you $1k a year" trade-off banks like to highlight when they push first-home buyers to nudge over the line.
Things to keep in mind
- LVR is calculated on bank value, not purchase price. When the bank’s registered valuer puts the property at less than the purchase price, the bank uses the lower figure. The deposit you need is calculated against that valuation, not the price you negotiated.
- KiwiSaver First Home Withdrawal counts as deposit. Funds released under a First Home WithdrawalFirst Home WithdrawalPermission to withdraw KiwiSaver balance (minus $1,000) toward buying your first home.View in glossary → sit on the deposit side of the LVR calculation, not the loan side. The minimum that has to remain in the KiwiSaver account is $1,000.
- Investor LVR is tighter. For owner-occupiers the standard line is 80% LVR. For investors it sits at 70% LVR, with banks holding only 5% of new lending above that cap rather than 20%. New-build lending has its own carve-out at 80% for investors.
- High-LVR carries a low-equity margin or premium. Banks price loans above 80% LVR with a low-equity margin (a permanent rate add-on while LVR stays high) or a low-equity premium (a one-off fee at drawdown). The two structures cost broadly similar amounts over the life of the loan, with different cash-flow profiles.
- Equity rises with repayments and house prices. LVR drops as you pay down the principal and as the property value rises. Banks usually let you re-test LVR every two or three years to remove a low-equity margin once you have crossed back under 80%.
NZ-specific notes
FAQs
What counts as the "value" in LVR?
The bank uses the lower of the registered valuation and the agreed purchase price. For an existing home, banks typically commission a registered valuer (around $700-$1,200) or accept an e-valuation if the property is recent and standard. For a new build, the contract price plus any signed variations stands until the property is complete.
How is high-LVR lending priced?
Banks add a low-equity margin or premium for loans above 80% LVR. Margins are usually expressed as a basis-point add-on to the contract rate (for example +0.50% for 80-85%, +1.00% for 85-90%, +1.50% for 90-95%). Some banks fold the cost into a single up-front low-equity premium fee instead. The total cost over the life of the loan is broadly similar between the two.
Does KiwiSaver count toward my deposit?
Yes. A KiwiSaver First Home Withdrawal lets you take most of your balance (leaving at least $1,000) toward a first-home deposit, in combination with personal savings and the Kāinga Ora First Home Grant if you qualify. The withdrawal sits on the deposit side of the LVR calculation.
Why is the investor LVR cap so much tighter?
The Reserve Bank set the 70% line for investors based on data showing investors default at higher rates than owner-occupiers when prices fall. The tighter cap forces investors to bring more equity into the deal, which reduces the systemic risk of forced sales in a downturn.
Can I get above 80% LVR as an owner-occupier?
Yes, banks reserve part of their lending capacity for above-80% loans. The 20% headroom is allocated bank-by-bank and tends to go to first-home buyers and applicants with strong income or stable employment. The pricing add-on still applies.
How quickly does LVR drop?
Repayments chip at the principal slowly in the early years (most of each fortnight goes to interest), but house-price growth and any extra payments speed up the drop. A $580,000 loan on a $720,000 house at 80.6% LVR can fall under 80% within a year if either of the underlying numbers moves a few percent in your favour.
