What it means
This works out what you would pay each month on a mortgage, and how much interest you would pay over the whole term.
Buying
Mortgage repayment calculator
What you would pay each month, and how much interest you pay over time.
Why it matters
The monthly figure is what has to fit your budget. The interest total shows how expensive the loan is beyond the house price.
When to use it
Use it when you have a price, deposit, rate and term in mind, or when you want to see how changing any of those moves the payment.
How to read the result
A lower monthly figure is easier to live with. A shorter term or lower rate usually cuts total interest. This is an estimate, not a lender quote.
Your figures
Defaults to price minus deposit.
