We have offered a downloadable Windows application for calculating mortgages for many years, but we have recently had a number of people request an Excel spreadsheet which shows loan amortization tables.
Our Simple Excel loan calculator spreadsheet offers the following features:
The calculator updates results automatically when you change any input.
loan amount - the amount borrowed, or the value of the home after your down payment.
interest rate - the loan's stated APR. For your convenience, we publish local Seattle mortgage rates below to help you see currently available rates.
loan term in years - most fixed-rate home loans across the United States are scheduled to amortize over 30 years. Other common domestic loan periods include 10, 15 & 20 years. Some foreign countries like Canada or the United Kingdom have loans which amortize over 25, 35 or even 40 years.
payments per year - defaults to 12 to calculate the monthly loan payment which amortizes over the specified period of years. If you would like to pay twice monthly enter 24, or if you would like to pay biweekly enter 26.
loan start date - the date which loan repayments began, typically a month to the day after the loan was originated.
optional extra payment - if you want to add an extra amount to each monthly payment then add that amount here & your loan will amortize quicker. If you add an extra payment the calculator will show how many payments you saved off the original loan term and how many years that saved.

US 10-year Treasury rates have recently fallen to all-time record lows due to the spread of coronavirus driving a risk off sentiment, with other financial rates falling in tandem. Homeowners who buy or refinance at today's low rates may benefit from recent rate volatility.
