Calculate your monthly repayments or find out how much you can borrow. Free, instant results, then speak to an adviser for a personalised mortgage recommendation.
These figures are illustrative only and do not constitute financial advice. Actual rates, fees, and payments will vary based on your individual circumstances, credit profile, and the lender's current criteria. Always speak to a qualified mortgage adviser before making a decision.
Affordability estimates are illustrative only. Actual borrowing limits depend on your credit profile, outgoings, lender stress-testing at higher rates, and individual lender criteria. Debts and commitments can significantly reduce your borrowing capacity. Speak to a qualified adviser for a precise assessment.
Enter the total loan amount you want to borrow, this is the purchase price minus your deposit. Then set your expected interest rate and the length of your mortgage term. The calculator will show your monthly payment, the total amount repaid over the full term, and the total interest cost.
Tip: Use the interest rate slider to see how sensitive your payments are to rate changes. Even a 0.5% increase in rate has a material impact on your total interest bill over a 25-year term.
The interest-only option shows what you'd pay if you were servicing the debt only, useful for buy-to-let investors who typically hold investment mortgages on an interest-only basis.
Enter your gross annual salary (before tax). If you're applying jointly, add your partner's income too. The calculator shows estimated borrowing at three common income multiples: 4x (typical high-street), 4.5x (most mainstream lenders), and 5x (available to higher earners and professionals).
Adding any monthly debt commitments, car finance, personal loans, credit card minimums, helps reflect how these reduce your available borrowing. Lenders count these commitments against your affordability.
Adding your deposit lets the calculator show your maximum property value, your deposit as a percentage, and the resulting loan-to-value. A lower LTV means access to better rates.
LTV is your mortgage as a percentage of the property value. A £160,000 mortgage on a £200,000 property is 80% LTV. It's the single most important factor in determining your mortgage rate.
| LTV | Rate Tier | Notes |
|---|---|---|
| 95% | Highest | Limited lenders; Mortgage Guarantee Scheme |
| 90% | Higher | Wider choice; rates improving |
| 85% | Competitive | Mid-tier pricing |
| 75% | Best available | Full market access |
| 60% | Lowest | Premium lender pricing |
Your LTV is fixed at the point of application but will fall as you repay capital or as your property rises in value, making remortgage reviews valuable over time.
On a repayment mortgage, each monthly payment covers both capital (reducing your debt) and interest. At the end of the term, your mortgage is fully paid off and you own the property outright.
On an interest-only mortgage, you pay only the interest each month. The original loan amount remains unchanged throughout the term. You'll need a credible repayment vehicle, typically the sale of the property or an investment, to clear the balance at the end.
Interest-only is common for buy-to-let investors where the monthly rental income needs to cover the mortgage comfortably. For most residential buyers, repayment is the right choice.
