Loan-to-value (LTV) is the single biggest driver of the mortgage rate you're offered. UK lenders price in bands — 60%, 75%, 80%, 85%, 90%, 95% — and the difference between the top and bottom band is typically 0.4-0.8 percentage points, worth hundreds of pounds a month over the life of a fix. This calculator shows your current LTV, the band it puts you in, the typical UK 2026 rate range for that band, and how much extra deposit gets you into a cheaper band.

UK 2026 LTV bands — typical 5-year fix rate ranges

LTV band	Deposit	Typical 5yr fix rate	Who typically qualifies
≤ 60%	40%+	4.15% - 4.45%	Downsizers, higher-earner second-time buyers, cash-heavy first-timers
60.01% - 75%	25% - 40%	4.30% - 4.60%	Second-time buyers with meaningful equity
75.01% - 80%	20% - 25%	4.45% - 4.75%	Second-time buyers, higher-earner first-timers
80.01% - 85%	15% - 20%	4.65% - 4.95%	Mainstream first-time buyers
85.01% - 90%	10% - 15%	4.85% - 5.20%	Standard first-time buyers
90.01% - 95%	5% - 10%	5.20% - 5.65%	First-time buyers stretching to buy sooner

Rate ranges are typical mainstream-lender 5-year fixed rates for standard residential purchases in August 2026. Individual quotes vary by credit history, income multiples, property type, and lender-specific criteria. Buy-to-let and specialist lending rates run 0.5-1.5 percentage points higher.

Why the band matters more than the deposit amount

Lenders don't price mortgages linearly. A borrower at 85.1% LTV is quoted the 90% LTV band rate — that 0.1 percentage-point difference in LTV can cost 0.20-0.35 percentage points on rate, which compounds to thousands over a 5-year fix. Getting under the band cut-off is one of the highest-return moves in mortgage preparation.

This calculator shows the exact gap. If your current LTV is 86% and the next band cut-off is 85%, the calculator tells you the extra deposit needed to reach 85% and the typical rate saving. Often the answer is £2,000-£5,000 of extra deposit unlocking £30-£70/month of lower payment — an obvious win.

Down-valuation risk at higher LTVs

Property surveys during the mortgage application sometimes down-value the property below your agreed offer. This is especially common at 90-95% LTV where lenders' surveyors are more conservative. A £5,000 down-valuation on a £280,000 property at 90% LTV means you need £4,500 more deposit to keep the same LTV — or you renegotiate the price, add cash, switch lender, or walk away.

Building a small deposit buffer above the band cut-off protects against this. If you're aiming at 85% LTV, target 83-84% actual LTV to absorb a plausible down-valuation. Read the why was my mortgage declined guide for more on how lenders assess valuation risk.

LTV interaction with stamp duty and other costs

LTV doesn't affect SDLT directly — the tax is calculated only on the purchase price. But a lower LTV (bigger deposit) leaves more cash headroom to absorb the SDLT bill without borrowing extra. Model the whole cost stack with the SDLT calculator, the home buying cost calculator, and the moving costs calculator. A £30,000 SDLT bill on top of a 90% LTV mortgage often forces buyers to reduce their deposit — pushing LTV up into the more expensive band. Plan the SDLT number early.

How LTV drops over time

Your LTV falls over the life of the mortgage two ways:

1. Capital repayment — every monthly payment on a repayment mortgage reduces the outstanding balance, lowering the numerator. In year 1 of a 25-year term at 5%, roughly 27% of each payment is capital; by year 20 it's roughly 84%.
2. Property appreciation — if your property rises in value, the denominator grows and LTV falls. Historic UK long-run average is 3-5%/year but individual years vary massively.

By the time your first fix ends (typically 2-5 years), a combination of capital repayment and any price movement often puts you into a cheaper LTV band for the remortgage. Use the mortgage repayment calculator to see your amortisation schedule and estimated balance at year 2, 5, and 10.

LTV thresholds for specific mortgage types

Mortgage type	Typical max LTV	Notes
Standard residential (buy)	95%	Standard mainstream-lender ceiling
Standard residential (remortgage)	90-95%	Some lenders cap remortgages tighter than new-purchase LTV
Buy-to-let	75-80%	Rental stress test applies; 25% deposit minimum
Limited company BTL	75%	Rates typically 0.3-0.5pp above personal BTL
First-time buyer (100%)	100%	Specialist products (Skipton Track Record, Barclays Springboard) with rental history or guarantor
Shared ownership	95% of share value	Not of full property value; effective loan much lower
New-build house	85-90%	Lenders often cap new-build LTV lower than second-hand stock
New-build flat	85%	Tightest LTV cap in the mainstream market

Frequently asked questions

What is loan-to-value (LTV)?

Loan-to-value is the size of your mortgage expressed as a percentage of the property price. A £270,000 mortgage on a £300,000 home is 90% LTV.

What LTV do I need for the best mortgage rates?

Sub-60% LTV unlocks the cheapest UK mortgage rates. 75-80% LTV is where rate cliffs meaningfully improve. Most FTBs sit at 85-95% LTV.

What's the maximum LTV in the UK?

Standard mortgages cap at 95% LTV. Specialist 100% LTV products exist (Skipton Track Record, Barclays Springboard) with guarantor or rental-history requirements. BTL caps at 75-80%.

How is LTV calculated?

LTV = mortgage amount ÷ property value × 100. Lenders use the lower of offer price and their surveyor's valuation.

What happens if my property is down-valued?

Your LTV rises. Options: renegotiate price, add deposit, switch lender, or walk away. Build a small buffer above band cut-offs to absorb this risk.

Does the LTV band matter more than the deposit size?

Yes for mortgage pricing. Getting under a band cut-off (60%, 75%, 80%, 85%, 90%) is worth more than extra deposit that leaves you in the same band.

How does LTV affect stamp duty?

LTV doesn't affect SDLT — SDLT is calculated only on the property price. But LTV affects overall affordability and cash headroom.

Can I reduce my LTV during my mortgage term?

Yes — via capital repayments and property appreciation. Both matter at remortgage: lower LTV unlocks cheaper rates.
