Assumptions and limits⌄
Reaching an LTV band does not guarantee a particular mortgage rate, product availability or lender approval. This is not financial advice and does not assess affordability, credit history, valuation or lender criteria. Buying costs are separate from the deposit and mortgage. Deposit sources determine target shortfalls and the maximum property price illustration.
Common LTV bands
Deposit needed by band
| Target LTV | Total deposit needed | More needed |
|---|---|---|
| 95% | £15,000 | Reached |
| 90% | £30,000 | Reached |
| 85% | £45,000 | £15,000 |
| 80% | £60,000 | £30,000 |
| 75% | £75,000 | £45,000 |
| 60% | £120,000 | £90,000 |
How it works
Connect the property price, deposit and mortgage
Loan-to-value, usually shortened to LTV, is the mortgage amount divided by the property value and expressed as a percentage. On a £300,000 property with a £30,000 deposit, the mortgage is £270,000 and the LTV is 90%.
The calculator can solve the same relationship from any two valid inputs: property price and deposit, property price and mortgage, property price and LTV, deposit and mortgage, deposit and LTV, or mortgage and LTV. It assumes one mortgage and that the deposit plus mortgage equals the property price.
Cash, existing equity and a gift can be listed separately and are added to form the available deposit. A lender and conveyancer will still need evidence of the source, availability and acceptability of the funds.
Understanding your result
Use target bands as planning illustrations
The result shows the calculated property price, total deposit, mortgage and LTV. The band table then calculates the deposit that would be needed at 95%, 90%, 85%, 80%, 75% and 60% LTV using the same property price.
A lower LTV means funding more of the property with the deposit and borrowing a smaller proportion. It can increase the range of mortgages available and may affect pricing, but reaching a particular percentage does not guarantee a product, rate or approval. Lender bands and criteria vary.
The target-LTV result shows either the extra deposit needed for the current property price or the maximum illustrative property price supported by the available deposit at that target. It does not test whether the resulting mortgage is affordable.
Worked example
Moving from 90% to an 85% target
With the default £300,000 property price and £30,000 deposit, the required mortgage is £270,000 and the calculated LTV is 90%. The deposit represents the remaining 10% of the price.
An 85% LTV mortgage on the same property would be £255,000, requiring a £45,000 deposit. The calculator therefore shows a £15,000 shortfall against the selected target. Alternatively, £30,000 supports a maximum property price of £200,000 at 85% LTV, before affordability is considered.
The default £2,500 buying-cost estimate is shown separately. Keeping that amount available does not increase the deposit or reduce the mortgage in the calculation.
Deposit sources and buying costs
Confirm when and how each source can be used
Existing equity is the property value left after mortgages and other secured borrowing are repaid. An estate-agent estimate is not guaranteed sale proceeds, and the timing of a related sale can affect when the money becomes available.
A gifted deposit may need a declaration confirming whether it is repayable and whether the donor expects an interest in the property. Lenders, conveyancers and anti-money-laundering checks can require identification, bank statements and evidence tracing the source of funds.
Buying costs are not part of the deposit in this calculator. Keep enough separate for applicable property tax, legal work, searches, surveys, valuation or mortgage fees, removals and other purchase costs.
Assumptions and limitations
The lender’s valuation can change the calculation
The calculator uses the property value you enter. A mortgage lender will obtain or review a valuation and can use a lower figure than the agreed price. A down-valuation can increase the effective LTV or require a larger deposit to retain the intended mortgage.
The calculation does not assess income, expenditure, credit history, mortgage affordability, property eligibility or whether a lender accepts a particular deposit source. It also excludes second charges, shared-equity loans and other secured borrowing unless their effect has already been reflected in the figures entered.
Purchase price is not a prediction of future value. With a high LTV, a fall in property value can reduce equity or create negative equity, which may affect selling or remortgaging.
