Mortgage calculators

When you take out a mortgage to purchase a property, your deposit is the amount of money you provide up front towards the total purchase price of the property.

The minimum deposit you need for a mortgage with NatWest International is 10% of the purchase price of the property. This means, if you were buying a property for £300,000, you would need a mortgage deposit of £30,000.

You can use our mortgage calculator to get a quick indication of how much a mortgage could cost with different deposit amounts.

It makes sense to use the calculator if you're considering buying a property or remortgaging when your current mortgage deal is about to end. You can use it to get an initial understanding of what you may be able to afford, monthly repayments and potential interest rates.

No, using our mortgage calculators won't have any impact on your credit score. We only conduct a credit check if you apply for a mortgage with us.
