What this means

The mortgage payment would take about 30% of your income before tax.

This is the most lenders’ rules allow, not what’s comfortable. Buying below it leaves room for saving, repairs and higher rates when your deal ends.

Assumptions in this estimate

Most lenders lend up to 4.5 times your income (combined if you buy with someone), and some go higher. Lenders also check your spending and debts, so you may be offered less.
You need a deposit of at least 5%. Your savings pay the Stamp Duty (or LBTT or LTT) first, and the rest goes towards the deposit. Legal fees and moving costs are extra.

How the calculator works

It finds the highest price where:

Your income: the mortgage is no more than your lender’s income multiple (4.5 times, unless you choose another) times your yearly income.
Your savings: they pay the Stamp Duty first (LBTT in Scotland, LTT in Wales), and what’s left covers at least a 5% deposit.

Whichever limit you hit first sets your price. Change the multiple, rate and term under More options.

Other costs

The calculator counts Stamp Duty for where you’re buying, but not solicitor and survey fees or moving costs, so keep some savings back for them. Our stamp duty calculator shows how the Stamp Duty is worked out.

Frequently asked questions

How much can I borrow on a £50,000 salary?

Most lenders lend up to 4.5 times your income, so about £225,000. With a 10% deposit of £25,000, that buys a home up to £250,000, with repayments of about £1,263 a month at 4.6% over 25 years. As a first-time buyer in England, you'd pay no Stamp Duty at that price.

How many times my salary can I borrow?

Usually up to 4.5 times your income, or your combined income if you buy with someone. Some lenders go higher, up to 5 or 5.5 times for some buyers, but only a limited share of loans can be at 4.5 times income or more.

How much deposit do I need?

At least 5% of the price. The government's Mortgage Guarantee Scheme backs 91–95% mortgages for first-time buyers and home movers. A bigger deposit usually gets you a lower rate.

Will a lender really offer this much?

Not always. Lenders also look at your spending, debts and credit history, and check you could cope if rates rose. Use this as a guide, then get an agreement in principle.
