An estimate of how much lenders may be willing to lend to you

Monthly repayment (incl. interest)
Based on the information provided, your mortgage will cost as follows:
Repayment (pm)
Interest only (pm)
Loan to value
Stamp duty payable
Repayment (pm) + interest rate increase
Interest only (pm) + interest rate increase
The monthly repayment is for a straightforward repayment mortgage. It includes both interest and repayment towards the capital loan amount. This reduces the amount owed on the capital, month by month.
The interest only shows the amount of interest due on the loan. If you opt for an interest-only mortgage such as one linked to an endowment, ISA or pension savings policy, you will need to factor in the cost of those policy premiums. On maturity, the savings policy is intended to pay off the capital loan.
These figures are only a guide. We'd be very happy to discuss them with you in further detail.
Mortgage option #1
Mortgage option #2
Based on the information provided, the options compare as follows:
Mortgage option #1

This calculator assumes that interest rates do not change during the term, and that you pay the fees upfront.

Interest rate curves
Our rate curves are updated weekly. They should give you an idea of how mortgage pricing is affected by the duration of the mortgage as well as the loan-to-value ratio (LTV).
How does your LTV affect your mortgage?
It affects the amount you can borrow, and the rate at which you can borrow. The lower your LTV rate, the wider and better your mortgage rate options will be. Your LTV rate is directly affected by the size of your deposit. The bigger your deposit, the lower your risk profile, the lower your LTV. Conversely, the smaller your deposit, the higher your LTV. The curves below have been generated based on a first-time buyer purchasing a £400,000 property.
| Loan To Value (LTV) | ||||||
| 60 | 70 | 75 | 80 | 85 | 90 | |
| Fixed | ||||||
| Variable | ||||||
A note on yield curves
These interest rate curves are driven primarily by interest expectations in the market. These expectations are best illustrated by yield curves.
Yield curves show the interest rates, or yields, of government bonds with different maturation dates. Government bonds are heavily traded, highly liquid instruments. They operate as the primary collateral for transactions between banks. They are also the mechanism for monetary policy in the economy and illustrate the "mind of the market" around the issue of interest rate expectations.
Yield curves drive the retail mortgage market pricing through the interest rate swap market. However, that transmission mechanism has a lag. Changes to yield curves can be a lead indicator for changes to mortgage market pricing. When we you on your mortgage, we are always comparing yield curves against mortgage pricing to get a feel for pricing opportunities.
