Mortgage Early Repayment Charge Calculator
Mortgage Early Repayment Charge Calculator
Results:
When you take out a mortgage, you usually agree to repay it over a long-term period such as 15, 20, or 30 years. But many homeowners want to repay their mortgage earlier than scheduled—either through lump sum payments, refinancing, or selling their property. While this can save thousands in interest, some lenders impose an Early Repayment Charge (ERC) as a penalty.
To make sure you understand the financial impact, the Mortgage Early Repayment Charge Calculator helps you estimate the cost of paying off your mortgage early, compare your potential interest savings, and decide whether it’s the right move.
What is an Early Repayment Charge (ERC)?
An Early Repayment Charge is a fee that some lenders apply if you repay part or all of your mortgage before the agreed term. The charge is usually:
- A percentage of the outstanding balance (commonly 1%–5%)
- Applied only during a fixed or special rate period
- Designed to compensate the lender for lost interest income
For example, if you owe $200,000 and your lender charges a 3% ERC, you would pay $6,000 in fees for early repayment.
How the Mortgage Early Repayment Charge Calculator Works
This calculator requires just a few simple inputs:
- Outstanding Loan Balance – The amount you still owe on your mortgage.
- ERC Percentage Rate – The early repayment fee rate from your loan agreement.
- Extra Repayment Amount – The lump sum or full balance you want to repay early.
With these details, the calculator instantly computes:
- The Early Repayment Charge (ERC) you’ll owe.
- The potential interest savings if you repay early.
- The overall financial impact so you can decide if it’s worth it.

Practical Example
Imagine you have:
- Outstanding Loan Balance: $180,000
- Interest Rate: 4%
- Remaining Term: 20 years
- ERC Rate: 3%
- Lump Sum Repayment: $100,000
Without Early Repayment
- Monthly payment: $1,091
- Total interest: $82,000 over 20 years
With $100,000 Early Repayment
- ERC Fee: $3,000 (3% of $100,000)
- New balance: $80,000
- New payoff term: 9 years
- Total interest saved: $41,000
✅ Even after paying a $3,000 ERC, you save $41,000 in interest and cut 11 years off your loan term.
