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.
Think carefully before securing your debts against your home.
Your home may be repossessed if you do not keep up repayments on your mortgage.

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.

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.

How the LTV Calculator Works
The loan to value ratio is the loan amount divided by the property's purchase price or current market value, expressed as a percentage. Buying a £400,000 home with a £40,000 deposit means borrowing £360,000, which gives an LTV of 90%. Buying the same property with an £80,000 deposit means borrowing £320,000, giving 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 mortgage lenders price products in bands based on LTV. The main thresholds are typically 60%, 75%, 80%, 85%, 90% and 95%. Each band acts as a rate breakpoint. Moving from 91% to 89% LTV can shift you into a different rate tier, even though the change in borrowing is small.
The most competitive rates sit at 60% LTV or below, where lender risk is lowest. Rates step up at each band. At 95% LTV, the borrower pool is narrower, criteria are tighter and pricing is typically higher.
For first-time buyers, 90% and 95% LTV products are the standard route. For movers and remortgagers, equity built up in the existing property usually shifts the LTV downward at the next application. For buy-to-let mortgage rules, maximum LTVs are lower at typically 75% to 80%, and rental cover ratios apply on top.

Why LTV Matters to Lenders
LTV is one of the first numbers a lender looks at. It tells them how much equity is sitting behind the loan. Higher equity means lower lender risk in a falling-market scenario. That is why pricing tightens at lower LTVs and loosens at higher ones.
LTV also interacts with affordability, credit profile and property type. Two applicants with identical income but different deposits will see different rates. 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
There are four practical ways to move your LTV into a more favourable band.
First, increase the deposit. Even a 1% to 2% deposit increase can cross a band threshold and 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.

Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.
This calculator provides indicative figures only and is for information purposes. It does not constitute mortgage advice or a guarantee of borrowing. Buy-to-let affordability is assessed by each lender using their own criteria, which may include (but is not limited to) stressed interest rates, ICR, maximum LTV, fees, property type, portfolio status, and borrower tax position. If you are unsure what stressed rate or ICR applies to your circumstances, please seek professional advice. For tax treatment, speak to a qualified accountant.

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.
