Mortgage Calculator for Help to Buy Borrowing

Free Help to Buy mortgage calculator to support UK applicants understand their borrowing limits, available financing, and anticipated monthly mortgage repayments.

Get Started

Help-to-buy Loan Calculator

Help to Buy equity loans are available only for new-builds, and there are lots of calculators online. The problem is that nearly all calculators will return a different result because they can only be based on averages and estimates.

While a calculator is useful to get a rough idea about what you might be able to borrow, or what your monthly repayments might be, they are never entirely accurate.

Calculators can also cause confusion since they cannot consider whether you meet the lender's eligibility criteria. That can cause issues if you proceed with an application, only to find you do not meet them - and rack up credit checks on your credit file that diminish your chances of approval elsewhere.

Here we'll run through how calculators work, and what information they use. For more detailed quotes and help to find a Help to Buy lender, give the Revolution Brokers team a call on 0330 304 3040, or email us at [email protected].

Which Help to Buy Mortgage Calculators are Best?

You can find several mortgage calculators on the Revolution Brokers calculator pages - but again, these are only useful for a rough indication.

Enter the details about how much you need to borrow, how much deposit you have, and how much you earn, and you'll get an idea about the maximum mortgage you might be able to secure.

Most lenders will let you borrow 4.5 times your annual salary so, as long as you have a standard 10% deposit, you should be able to borrow this much.

£0

Depending on your personal circumstances, some lenders may let you borrow 5 times your salary.

Lenders usually cap the amount they lend at 5.5 times your salary, so it’s unlikely you’ll be able to borrow more than this.

How Can I Calculate my Maximum Help to Buy Mortgage Value?

Generally, UK lenders offer mortgages up to 4.5 times your annual salary.

The below table gives you an idea about how much mortgage you can borrow, assuming you have the minimum 5% deposit required. For this illustration, we have used a 3% interest rate.

Value of the property	5% deposit	20% Help to Buy loan	Mortgage required
£100,000	£5,000	£20,000	£75,000
£150,000	£7,500	£30,000	£112,500
£200,000	£10,000	£40,000	£150,000
£250,000	£12,500	£50,000	£187,500

How Does the Interest Calculation Work on a Help to Buy Loan?

Your Help to Buy equity loan is interest-free for the first five years. After that, interest is charged at 1.75%.

The interest rate increases each year, based on the Retail Price Index plus 1%.

As an example, the below table shows the interest payable on the loan each year, on a property purchase of £200,000 with a 20% equity loan of £40,000, based on an RPI of 5%:

Year	Interest rate RPI + 1%	Annual interest cost
Years 0-5	0%	£0
Year 6	1.75%	£700
Year 7	1.86%	£744
Year 8	1.97%	£788
Year 9	2.08%	£832
Year 10	2.21%	£840

Remember that this is the interest payable on only the equity loan - the capital remains outstanding, and this does not include your mortgage repayments.

As an example, if you take out a £200,000 mortgage, in year seven your equity loan will cost £744 per year in interest, in addition to your monthly mortgage costs of £711.

How Do the Calculations for Help to Buy Loan Repayments Work?

You can repay the Help to Buy loan at any time, or need to repay the full balance if you sell the home.

Part payments mean that you gradually buy back the equity shares until you own all of the property. This reduces your interest charges and is called staircasing.

If you are interested in paying back the equity loan in this way:

You need to keep up with the mortgage repayments.
Each payment towards the capital of the equity loan must be at least 10% of the property value.
Some lenders have other criteria around staircasing payments.
When you want to make a repayment, you will need to cover the valuation costs of an independent survey.

As your property value grows, so too does the value of the equity share owned by the government.

If you need support with budgeting for buying back equity shares, or to understand the long-term costs against a typical mortgage product, give us a call on 0330 304 3040.
