Repayment versus interest-only
Most UK residential mortgages are repayment (also called capital and interest): each payment chips away at the balance, and by the end of the term you own the home outright. Interest-only mortgages keep the balance fixed and only cover the interest, so the monthly payment is lower but you must repay the full capital at the end, usually from savings or a sale. This calculator models a repayment mortgage, the standard choice for buyers.
Fixed deals and the SVR
UK borrowers usually take a fixed-rate deal for two, five, or ten years, then roll onto the lender's higher standard variable rate unless they remortgage. Fixed deals track the Bank of England base rate at the time you fix. Because the rate can change when your deal ends, it is worth modelling both your current rate and a higher one to see how the payment might move.
