How this estimate works

This calculator models a capital-and-interest repayment mortgage with monthly payments. It assumes the same interest rate applies for the entire term. In reality, rates can change when a deal ends. It excludes product fees, legal costs, insurance and taxes. Figures are rounded to the nearest pound and do not tell you what a lender will offer or what you can afford.

If the interest rate is zero, the loan is divided equally across the number of monthly payments. A longer term normally lowers the monthly repayment but increases the total interest.

Mortgage terms
explained.

Loan to value

The mortgage as a percentage of the property value. A £340,000 mortgage on a £400,000 property has an 85% loan to value. The rest would be your deposit or equity.

Fixed rate

The interest rate stays the same for an agreed period. Your deal may include early repayment charges, and the rate will usually change when that period ends.

Variable rate

The interest rate can change. With a tracker, it follows a reference rate under the terms of the deal. With a lender’s standard variable rate, the lender sets the rate.

Mortgage term

The overall time allowed to repay the mortgage. This is different from the deal period, such as a two-year or five-year fixed rate.
