Work out your loan-to-value ratio using the property value and your deposit or equity. See your current LTV band, how much you are borrowing, and the extra cash you may need to reach a lower mortgage tier such as 90%, 85% or 75%.
LTV is usually mortgage required ÷ property value. Lower LTV bands often unlock sharper mortgage rates, but lenders also check income, credit profile and affordability. Fees are shown separately because they do not normally count towards LTV unless they are added to the mortgage.
This calculator compares your deposit or equity against the property value to work out the share being borrowed. It then checks how far you are from your chosen target LTV tier.
Loan to value is the percentage of a property's value that is funded by borrowing. If a home is worth £300,000 and you need a £255,000 mortgage, your LTV is 85%. In plain English: you are borrowing 85% and funding the other 15% with deposit or equity.
Many mortgage deals cluster around bands such as 95%, 90%, 85%, 80%, 75% and 60%. A small extra deposit can sometimes move you into a lower band and improve the rate available.
Always check the full mortgage cost, not just LTV: fees, product transfers, early repayment charges and affordability rules can matter just as much as the headline rate.
