Calculate the cost of early repayment charges (ERCs) on a UK mortgage. See if paying the penalty to leave your deal early could save you money in the long run.

Net Saving: £12,000.00
An Early Repayment Charge (ERC) is a penalty fee you may have to pay if you want to leave your mortgage deal before it officially ends. Lenders in the UK commonly include these charges on fixed, discounted, or tracker rate mortgages to protect their expected profit from the interest they would have otherwise received.
This Calculator Site tool helps you weigh up the costs. It calculates the ERC based on your outstanding balance and the lender's percentage. Then, it estimates the amount of interest you would save by switching to a new deal for the remainder of the penalty period. By comparing these two figures, you can get a clear indication of whether breaking your current deal is a sound financial decision.
The ERC Trap: Why Leaving Early Can Be Costly
The ERC is designed to be a significant deterrent. For example, a 3% charge on a £200,000 outstanding balance is a £6,000 fee. This is often the biggest hurdle when considering a remortgage. While our Remortgaging Savings Calculator can show potential benefits, you must first account for the ERC cost.
The decision comes down to a simple cost-benefit analysis. If the total interest you would save by moving to a new, lower-rate mortgage is greater than the ERC penalty, it can be a financially advantageous move. This calculator provides the verdict by showing you the net financial outcome.
