Loan value over time explained

Illustration of loan value over time for monthly mortgage repayment calculator comparing interest-only and capital repayment mortgage.

The ‘loan value over time’ illustration explains how your loan value changes over the mortgage term.

In this example, the loan value over time is illustrated for a £500,000 mortgage with a 30 year mortgage term at an interest rate of 5.5%. If opting for a capital repayment mortgage, the individual would have repaid the full balance of the mortgage at the end of the 30 year mortgage term. However, if they had opted for a full interest-only mortgage, the full balance of £500,000 is due to be repaid at the end of the 30 year term.

In each year of the mortgage term, the principal payment is subtracted from the starting balance. This calculates the end balance for that year of the mortgage term. For a full repayment mortgage, the balance is fully paid by the term’s end.

With an interest-only mortgage, or if part of the mortgage is interest-only, known as a part and part mortgage, the interest portion remains due at the end of the mortgage term. The interest payments are not subtracted from the mortgage balance.

Mortgage Repayment Types Explained

Repayment Mortgage

A repayment mortgage, also known as a capital and interest mortgage, is the most popular option amongst borrowers for residential property. The mortgage repayments are made up of a capital payment used to repay the initial capital borrowed and some interest.

Interest-Only Mortgage Calculation

The monthly repayments only pay off the interest of the loan and not the initial capital borrowed. At the end of the mortgage term, the full mortgage amount will have to be repaid.

Part and Part Mortgage

A part and part mortgage offers a combination of both a repayment mortgage and an interest-only mortgage.

What interest rate can I get?

There are myriad variables which impact what interest rate you can get on your mortgage. To get a better idea of what mortgage rate you will be able to achieve, it is best to speak with an expert mortgage adviser who can guide you in the context of your financial and personal circumstances.

How will interest rates affect my mortgage?

A higher interest rate would increase your mortgage repayments, provided all other factors remain consistent. At the same time, a lower interest rate would result in lower monthly mortgage repayments.

In addition, the figures shown in respect of both repayment and interest only mortgages do not include the cost of additional life cover.
