The PMT function in Excel determines the total payment owed each period—inclusive of the interest and principal payment. The total payment, unlike the other two components, will remain constant over the entire borrowing term.
Fortunately, Excel can be used to create an amortization schedule. The amortization schedule template below can be used for a variable number of periods, as well as extra payments and variable interest rates.
Annual amortization expense is calculated as the ROU asset divided by the lease life. So, if the ROU asset at inception date was $60,000 and the lease life is 5 years, that results in amortization expense of $12,000 per year.
