How this calculator works
We work out the payment for your deal, then the payment once the deal ends and you move to the lender’s follow-on rate. The figures assume the rate stays the same for each part and you make every payment on time.

How Mortgage Payments Work
Interest First
In the early years, most of each payment goes on interest. As the balance falls, more of each payment pays off the loan itself.
When Your Deal Ends
Fixed and tracker deals last a set time. After that, you move to the lender’s standard rate unless you pick a new deal. Plan ahead to avoid a jump in payments.
Paying It Off Sooner
Most lenders let you overpay up to 10% of the balance each year during a deal. This cuts the interest you pay and can shorten your term. Try our overpayment calculator.
Monthly Cost per £100,000
| Rate | 25 years | 35 years |
|---|---|---|
| 4% | £528 | £443 |
| 5% | £585 | £505 |
| 6% | £644 | £570 |
| 7% | £707 | £639 |
Repayment mortgage. Interest-only costs £333 to £583 a month per £100,000 at the same rates.
Fixed or Tracker?
| Type | How it works |
|---|---|
| Fixed rate | Your rate and payment stay the same for the deal, often 2, 5 or 10 years. |
| Tracker | Your rate moves with the Bank of England base rate, so payments can rise or fall. |
| Standard variable | The lender’s own rate. It can change at any time and is usually higher. |

Lenders use the loan amount, the interest rate and the term. Each monthly payment covers that month’s interest, and on a repayment mortgage the rest pays off the loan.
You usually move to the lender’s standard variable rate, which is often higher. You can pick a new deal with your lender or remortgage to another lender, often up to six months before your deal ends.
A longer term lowers your monthly payment, but you pay interest for longer, so the total cost is higher. You can often overpay to clear it sooner.
Most people choose repayment, so the mortgage is cleared at the end. Interest only has lower payments, but you must have a plan to repay the full loan. Lenders check this plan carefully.
Lenders want to know you could still pay if rates went up. They check your budget against a higher rate before they make an offer.
Yes. Most deals let you overpay up to 10% of the balance each year without a charge. Our overpayment calculator shows how much you could save.
