Think carefully before securing debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage.

If you’re ready to buy a home, you might wonder how to budget for your target home cost. Here’s a breakdown of what you might face monthly in interest and over the life of an £800,000 mortgage.

Monthly payments on an £800,000 mortgage

At a 4% fixed interest rate, your monthly mortgage payment on a 30-year mortgage might total £3,819.32 a month, while a 15-year mortgage might cost £5,917.50 a month.

Note that your monthly mortgage payments will vary depending on your interest rate, taxes and PMI as well as on related fees.

Your total interest on an £800,000 mortgage

On a 30-year mortgage with a 4% fixed interest rate, you’ll pay £574,956.63 in interest over the life of your loan. That’s about two-thirds of what you borrowed in interest.

If you instead opt for a 15-year mortgage, you’ll pay £265,150.84 in interest over the life of your loan – or about half of the interest you’d pay on a 30-year mortgage.

What is the total amount repayable?

When you take out a mortgage, you agree to pay the principal and interest over the life of the loan. Your interest rate is applied to your balance, and as you pay down your balance, the amount you pay in interest charges.

This means that at the beginning of your loan, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your balance.
