Mortgage rate change monthly payment estimate

Use your remaining balance

The estimate is only useful if the balance and remaining term are close to your real mortgage statement.

Enter rises and cuts differently

Use a positive number for a rate rise, such as 1.25, and a negative number for a cut, such as -0.75.

Treat it as a planning estimate

Real lender figures can include fees, daily interest, overpayments and product-specific rounding. Use the result to understand scale, not as a final quote.
