LTV Calculator: Mortgage Bands, Rate Tiers and Deposit Steps
Our LTV calculator works out your loan to value ratio for any UK mortgage in seconds. Enter the property value and the loan amount, and the tool returns your LTV as a percentage. That number drives which lender bands you can borrow within, which interest rate tiers you qualify for, and how much deposit you need to move to the next band. Use it to plan a purchase, sense-check a remortgage or compare options before applying.

Loan to Value (LTV) Calculator
This tool calculates your loan-to-value (LTV) ratio using the loan amount divided by the property’s purchase price or value. The figure is indicative only. Individual lenders may use their own criteria, including treatment of fees, deposits, and valuations. Always speak with a qualified mortgage adviser before relying on LTV figures.

How the LTV Calculator Works
Loan to value is your mortgage amount divided by the property’s price or value, shown as a percentage. Buy a £400,000 home with a £40,000 deposit and you borrow £360,000, an LTV of 90%. A larger £80,000 deposit cuts the loan to £320,000, an LTV of 80%.
Lenders work to maximum LTV thresholds. Most UK residential lenders cap at 95% LTV for standard purchases, while buy-to-let mortgages typically cap at 75% to 80%. The lower your LTV, the more lender options open up and the more competitively rates are typically priced. Pair this calculation with the how much you can borrow tool to size up the affordability picture before applying.
LTV Bands for UK Mortgages
UK lenders price mortgages in LTV bands, with the main breakpoints at 60%, 75%, 80%, 85%, 90% and 95%. Each band is a rate tier. The most competitive pricing sits at 60% and below, where lender risk is lowest, and steps up at every band to 95%, where criteria tighten and the borrower pool narrows.
• 60% LTV and below: the lowest pricing tier and the widest lender choice, suited to remortgagers and movers with substantial equity.
• 75% LTV: competitive residential pricing and the usual upper ceiling for buy-to-let products.
• 80% LTV: a solid mainstream rate tier for buyers with a 20% deposit.
• 85% LTV: rates step up for a 15% deposit, though lender choice stays wide.
• 90% LTV: the standard high-LTV tier for first-time buyers and movers with a 10% deposit.
• 95% LTV: the narrowest borrower pool, tightest criteria and highest pricing of the standard bands, for a 5% deposit.
For first-time buyers, 90% and 95% products are the standard route. Movers and remortgagers usually see their LTV fall as equity builds in the existing property. For buy-to-let mortgage rules, maximum LTVs are lower at typically 75% to 80%, with rental cover ratios applying on top.
A single percentage point can move you into a cheaper band and change your rate for the whole fixed period. A whole-of-market broker can tell you which band you land in and which lenders price it best. To talk through the LTV band you need for your circumstances, call 01202 155992 or contact Mortgage One
Why LTV Matters to Lenders
LTV is one of the first figures a lender checks, because it shows how much equity sits behind the loan. Higher equity means lower risk if prices fall, so pricing tightens at lower LTVs and loosens at higher ones. Two applicants on identical income but different deposits will be offered different rates.
LTV also interacts with affordability, credit profile and property type. A flat above commercial premises or a non-standard construction property may see LTV capped lower than a standard freehold house, regardless of deposit. For broader residential mortgage options, specialist lenders may extend higher LTVs in cases that high-street lenders decline, often with adjusted pricing to reflect the risk.
How to Reduce Your LTV Before Applying
Four practical levers move your LTV into a better band: increase the deposit, choose a lower purchase price, time a remortgage to property-value growth, or repay capital through overpayments. Even a one to two percentage point rise in deposit can cross a band threshold and unlock a different rate tier.
First, increase the deposit. Crossing a band threshold, sometimes by as little as a percentage point or two, can unlock a different rate tier.
Second, choose a lower purchase price. The same deposit on a cheaper property gives a lower LTV. This is often more achievable than waiting longer to save more.
Third, time a remortgage to coincide with property value growth. Lenders use either purchase price (for the first two years) or the higher of purchase price and surveyed value. Tracking the UK rate forecast alongside local property data can help time your next application.
Fourth, repay capital through overpayments during your current deal. Most fixed and tracker products allow 10% capital overpayment per year without early repayment charges. Five years of disciplined overpayments can move a 90% LTV mortgage closer to 75% by the next remortgage. Estimate the effect with the mortgage repayment calculator before committing.
If you are weighing a bigger deposit against keeping cash back, that is a numbers conversation worth having before you apply. We run both scenarios against live lender pricing. For specialist advice on positioning your LTV before you apply, call 01202 155992 or contact Mortgage One.

FAQs
1. How accurate is this LTV calculator?
The LTV calculator gives an indicative figure based on the loan amount divided by the property value or purchase price. Individual lenders may treat fees, incentives, valuation differences and additional borrowing differently when calculating LTV for underwriting. Always check the lender’s specific LTV definition before relying on a final figure.
2. What is a good LTV ratio for a UK mortgage?
Lower is generally better. LTVs at 60% or below typically attract the most competitive pricing tiers. For first-time buyers, 90% to 95% LTV is the standard starting point, with rates stepping up at higher bands. The right LTV depends on your deposit, the property type and your wider plans.
3. Can I use the LTV calculator for a buy-to-let mortgage?
Yes, the calculator works for any property type. Buy-to-let lenders typically cap LTV at 75% to 80% and apply additional affordability tests, including interest cover ratio (ICR) and stress-rate assumptions. The LTV figure is the starting point, not the full criteria check.
4. Does the LTV calculator include fees and stamp duty?
No. The calculator uses the loan amount and the property value or purchase price only. Fees, stamp duty, valuation costs and other purchase expenses sit outside the calculation. Some lenders allow you to add product fees to the loan, which can push the LTV up by a small amount.
5. What LTV bands do UK lenders typically offer?
The main LTV breakpoints for UK residential mortgages are 60%, 75%, 80%, 85%, 90% and 95%. Buy-to-let lenders generally stop at 75% or 80%. Specialist lenders may extend beyond standard bands in specific circumstances. Each band carries its own pricing tier.
6. How does LTV affect my mortgage interest rate?
Lower LTVs typically attract lower interest rates because lender risk is reduced. Crossing a band threshold (for example moving from 91% to 89% LTV) can step you into a different rate tier. Bringing the LTV down by a small amount before applying can change the rates available, depending on the lender.
