Because most UK homeowners base their remortgage decisions on a £200,000 loan, a 25‑year term, and a 3.5 % interest rate, the calculator illustrates how even modest rate shifts can alter monthly payments by several hundred pounds.
When you plug those figures into the tool, you’ll see the payment drops from £1,001 to £938 if the rate falls to 3.0 %, saving you £750 annually.
Conversely, a rise to 4.0 % pushes the monthly charge to £1,067, costing an extra £1,560 each year, which quickly erodes any budgeting cushion.

Double‑check every figure; precision now prevents costly surprises later.
