Work out if a mortgage fee is worth paying

Many remortgage deals charge an arrangement fee, also called a product fee, in exchange for a lower rate. This tool weighs that fee against the interest you'd save over your remaining term, using the numbers you enter. It is not a quote, and the result is only as good as the figures you put in.

How-To Guide

How the fee analyser works out what leaving your fix early could cost

The fee analyser estimates the early repayment charge, the fee your lender may apply if you leave your fixed-rate deal before it ends, using the numbers you enter. This guide is for anyone weighing up whether to remortgage now rather than wait for their fix to finish. It walks through what the tool needs from you and how to read the figure it gives back.

Level: Beginner
Best for: Homeowners with a fixed-rate mortgage who are considering switching before it ends
Fee analyser tool showing an estimated early repayment charge
  1. Enter your mortgage details

    You add your outstanding balance, the date your fixed rate ends and the rate you are on, so the analyser has what it needs to work with.

  2. See your estimated charge

    The analyser shows what leaving your current deal early could cost, based on the figures you have given it.

  3. Weigh the fee against a new deal

    You compare the estimated charge with what a new deal might save, so you can see whether switching before your fix ends is worth it.

True Cost Fee Analyser

Mortgage deals with low headline rates often carry large arrangement fees. This tool reveals the true cost of borrowing over your introductory deal period so you can compare products fairly — not just by the advertised rate.

True cost of borrowing (over the deal) £0.00 Interest actually paid during the deal period plus all fees. This excludes the principal you repay, because that money stays yours as equity in the property.
Total paid out during the deal £0.00 The actual cash leaving your pocket — every monthly payment made during the deal period plus all fees. This includes principal repayment.
Effective annual cost 0.00% The true cost of borrowing expressed as an annual percentage of the loan — a fair way to compare deals with different fees.
Monthly payment during the deal: £0.00

How this works

We amortise your mortgage at the deal rate over the full term, then look only at the payments falling inside your introductory deal period.

  • True cost of borrowing = the interest portion of those deal-period payments + arrangement fee + other fees. Repaid capital is excluded because it remains your equity.
  • Total paid out = monthly payment × number of deal-period months + arrangement fee + other fees. This is your actual cash outflow.
  • Effective annual cost expresses the true cost as an annual percentage of the loan, letting you compare a low-rate/high-fee product against a higher-rate/no-fee one.

Figures assume a repayment (capital & interest) mortgage and that the rate is fixed for the whole deal period. They are indicative estimates, not a formal illustration.

Weigh the fees against the savings before you switch

A new deal usually comes with its own costs: an arrangement fee, sometimes a valuation or legal fee, occasionally a broker fee. This tool sets those costs against what a lower rate would save you each month, so you can see whether switching actually leaves you better off. It works from the figures you enter, so the result is only as accurate as the numbers you put in.
