#mortgage amortization calculators
A mortgage amortization calculator shows how much of your monthly mortgage payment will go toward principal and interest over the life of your loan. The loan calculator also lets you see how much you can save by prepaying some of the principal.
How to use the loan amortization calculator
With HSH.com’s home loan calculator, you enter the features of your mortgage: amount of the principal loan balance, the interest rate, the home loan term, and the month and year the loan begins.
Your initial display will show you the monthly mortgage payment, total interest paid, breakout of principal and interest, and your mortgage payoff date.
Most of your mortgage loan payment will go toward interest in the early years of the loan, with a growing amount going toward the loan principal as the years go by – until finally almost all of your payment goes toward principal at the end. For instance, in the first year of a 30-year, $250,000 mortgage with a fixed 5% interest rate, $12,416.24 of your payments goes toward interest, and only $3,688.41 goes towards your principal. To see this, click on “Payment chart” and mouse over any year.
Clicking on “Amortization schedule” reveals a display table of the total principal and interest paid in each year of the mortgage and your remaining principal balance at the end of each calendar year. Clicking the “+” sign next to a year reveals a month-by-month breakdown of your costs.
Click “calculate” to get your monthly payment amount and an amortization schedule.
The effect of prepayments
Now use the mortgage loan calculator to see how prepaying some of the principal saves money over time. The calculator allows you to enter a monthly, annual, bi-weekly or one-time amount for additional principal prepayment.To do so, click “+ Prepayment options.”
Let’s say, for example, you want to pay an extra $50 a month. Using the $250,000 example above, enter “50” in the monthly principal prepayment field, then either hit “tab” or scroll down to click “calculate.” Initial results will be displayed under “Payment details,” and you can see further details in either the “Payment chart” or “Amortization schedule” tabs.
You may also target a certain loan term or monthly payment by using our mortgage prepayment calculator. Of course you’ll want to consult with your financial advisor about whether it’s best to prepay your mortgage or put that money toward something else, such as retirement.
HSH.com has developed a host of other free mortgage calculators to help answer your other questions, such as, “Can I qualify for a mortgage,” “Will prepaying my mortgage help me save money,” “How large of a down payment do I really need,” “What s the best way to pay for my refinance,” and “When will my home no longer be underwater?” See all of HSH.com’s mortgage calculators .
This is the dollar amount of the mortgage you are borrowing. (Hitting “tab” after entering information in any field will automatically update the calculations.)
The loan’s interest rate. Along with the term, this is the key factor used by the mortgage payment calculator to determine what your monthly payment will be. To see where rates are right now, click on the “See today’s average rates” link to the right of the field, where you can also find offers from our advertising partners.
Mortgage loans come in a range of terms. Fixed rate mortgages are most often found in 30, 20, 15 and 10-year terms; Adjustable Rate Mortgages usually have total terms of 30 years, but the fixed interest rate period is much shorter than that, lasting from 1 to 10 years.
To get the most accurate calculations, use the month and year in which your very first mortgage payment was due (or will be due). If you don’t yet have a mortgage, the current month and year will work just fine.
This display shows the monthly mortgage payment, total interest paid, breakout of principal and interest, and your mortgage payoff date.
This display shows you the total principal and interest paid in each year of the mortgage and your remaining principal balance at the end of each calendar year.
While this display table also shows you the total principal and interest paid in each year of the mortgage and your remaining principal balance at the end of each calendar year, clicking the “+” sign next to a year reveals a month-by-month breakdown of your costs.
In this optional section, you can add in a regular monthly prepayment amount, re-set the calculator to show bi-weekly payments and savings, or even do a one-time prepayment to see how it affects the cost of your home loan.
