Right-to-Buy mortgage calculator
Use our Right-to-Buy mortgage calculator to estimate your discounted purchase price, possible mortgage amount and whether your Right-to-Buy discount could help cover the deposit requirement.
The result is only an estimate. A lender will still need to assess your income, credit history, property, affordability and Right-to-Buy details before offering a mortgage.
Right-to-Buy details
Use the estimated market value of the property before the Right-to-Buy discount.
Enter the discount you expect to receive from your council or landlord.
Enter any separate cash deposit you have saved. Many Right-to-Buy buyers may enter £0 here.
Mortgage details
Use your total annual household income before tax.
Include regular commitments such as loans, credit cards, car finance or other debts.
Lender deposit assumption
Some Right-to-Buy lenders may accept the discount as deposit, but requirements vary. This setting lets you test different assumptions.

Your discount may cover the deposit requirement
Based on the figures entered, your Right-to-Buy discount and cash deposit may satisfy the selected deposit assumption. Some lenders may accept the discount as deposit, depending on their criteria.
This is only an estimate
The figures are not a mortgage offer or decision in principle. Lenders will still assess your income, credit history, property, affordability and Right-to-Buy details.
Discount treatment varies by lender
Some lenders may accept your Right-to-Buy discount as the deposit. Others may still ask for a separate cash deposit depending on your circumstances.
A mortgage adviser can help you understand whether your discount, income and wider circumstances are likely to fit suitable lender criteria.
How the Right-to-Buy mortgage calculator works
The calculator uses your estimated property value, Right-to-Buy discount and cash deposit to estimate the purchase price and mortgage amount.
It then uses your income, credit commitments, interest rate and mortgage term to show a rough borrowing range and estimated monthly repayment.
The figures are designed to help you understand the basic numbers before speaking to a mortgage adviser.
Can your Right-to-Buy discount be used as a deposit?
In some cases, yes. Some lenders may treat your Right-to-Buy discount as your deposit, which can mean you may not need a separate cash deposit.
This depends on the lender and the wider application. Your income, credit history, property value, discount amount and affordability can all affect your options.
Why the calculator shows two LTV figures
Right-to-Buy mortgages can be slightly different from standard purchases because there may be a gap between the market value and the discounted purchase price.
The calculator shows:
- LTV against the discounted purchase price
- LTV against the estimated market value
This helps show how the discount affects the overall mortgage position.
Why affordability still matters
Even if your discount helps with the deposit, lenders still need to check whether the mortgage is affordable.
They may look at your income, spending, debts, dependants, credit history, mortgage term and the property itself.
This is why two people with similar Right-to-Buy discounts may get different mortgage outcomes.
