Amortization Schedule Example in Excel (Mortgage)

Let us assume that there is a company that has $1,000,000 of loan outstanding, which has to be repaid over the next 30 years. The equated annual repayment will be made annually at an interest rate of 12%.

Therefore, as per the question,

• Outstanding loan = $1,000,000
• Rate of interest = 12%
• No. of period = 30 (since payments are annual)

Using the above information, we have calculated the Periodic Mortgage Payment for the Amortization Schedule excel table.

So the Periodic Payment will be–

Then we have calculated the interest paid using the formula mentioned above.

So the Interest Paid will be –

So the table below is the mortgage amortization schedule in excel based on the above information,

Therefore, from the above table, it can be seen that the total interest paid is $2,724,309.73 on a loan of $1,000,000, i.e., the interest paid is approximately 2.7 times the actual loan.
