# Excel Mortgage Repayment Calculator with Offset Account and Extra Payments

### What Is Mortgage Repayment Calculator with Offset Account?

According to the AMP website, an offset account can be linked to a loan account. The credit balance of this offset account will be deducted from the loan balance to calculate the interest rate, resulting in less interest paid by the lender.

For example, a borrower took a \$200,000 loan from the bank. He linked an offset account with a \$20,000 balance with the loan account. So he has to pay interest for \$(200,000-20,000) = \$180,000, which would definitely result in less interest than the actual loan interest.

This calculator deals with this type of loan repayment, calculating all necessary outputs, along with time savings and estimated interest savings.

### What Is Mortgage Repayment Calculator with Extra Payments?

Making extra payments when repaying a loan is a smart approach to repay the loan quicker than the initial deadline and save some interest to be paid. If somebody takes a loan with a fixed due payment for 30 years and after a while, if he makes some extra payments (regular or irregular), he can repay his loan before 30 years. It would save him some time and interest to be paid.

This calculator deals with this approach and calculates all necessary outputs, along with the time savings and estimated interest savings.
