Mortgage Amortization Calculator
A mortgage Amortization calculator is a cutting-edge financial tool that enables the borrower to arrive
at an annual/monthly mortgage schedule. The calculator can help the borrower to differentiate between
the amount being paid towards the outstanding principal and interest.

What Does Mortgage Amortisation Mean?
Mortgage Amortization refers to the process of paying off debts by repaying the regular
interest
and principal amounts before the mortgage tenure reaches maturity. An amortisation mortgage
has
a fixed interest rate for its entire tenure.
The primary characteristic of amortisation is that initially, a major chunk of your
EMIs
goes towards paying the interest amounts. But over time, as the interest amount decreases,
most
of your mortgage instalments go towards fulfilling your principal mortgage amount. An
amortisation is easier to manage than other debts as in it you know exactly when and how
much to
pay.
How to Calculate the Amortisation of a Mortgage?
An amortisation schedule lists the following items:
The principal and interest payable
The principal and interest that have been paid
The amount of principal owed on the maturity date
You can calculate the monthly amortisation amount by considering the mortgage amount and
interest rate.
Monthly payment= A [ I (1+i) ^ n / ((1+i) ^ n) - 1)]
What Do the Mortgage Amortisation Calculator Results
Mean?
The mortgage amortisation calculator offers results of multiple
variables with respect to a
mortgage.
Monthly Payment: The monthly payments include
how
much of the principal and interest amount you
are going to pay each month.
Total Principal Amount: The total principal
amount
is the total mortgage amount that you have
borrowed from the bank. It, therefore, equals the property price and closing costs (if any)
with
only the down payment amount subtracted.
Total Interest Amount: Covering a major chunk of
your mortgage cost, especially if you opt for a
full term of 15 to 30 years, is your total interest amount. To comprehend the true long-term
cost of borrowing, you can add your mortgage insurance premiums and closing costs to it.
Estimated Final Date of Payment: This is the
date
on which your mortgage tenure will mature.
Technically, it is the same date on which your mortgage amortisation starts. So, if your
mortgage amortisation of 30 years starts on May 1, 2022, its maturity date will be on May 1,
2052.
Running Total of Interest: It is the column in
the
amortisation schedule that shows you the total
interest amount you have paid in a year during your ongoing amortisation period. For
instance,
you have paid $5,000 in 2020, $7000 in 2021, etc.
Total Balance Remaining: This simply demonstrates the annual remaining
mortgage
amount that you
still have left to pay. It helps you understand how close you are to completing your
mortgage
repayment.
How to Speed Up Mortgage Amortisation?
Amortisation Periods: With shorter amortisation
periods, principal payments become higher, but the interest payable decreases drastically.
The
mortgage will be repaid earlier. This strategy should be used only if you can pay higher
instalments of the principal amount.
Extra Principal Payments: Longer amortisation
periods accelerate the payment. By using this method, you save more on interest. It adds
extra
payments to the monthly repayment. This strategy helps you become debt-free faster. For
example,
if a borrower has a $100,000 mortgage amortised over a tenure of 20 years with an rate of
interest of 6.45%, and they have repaid by paying extra principal, then they can save nearly
$30,000 over the mortgage term.
Lump Sum Payments: They are made in addition to regular payments to shorten
the
mortgage payment period. Such lump sum payments usually affect the earning potential of
banks;
therefore, the latter usually charge penalties or place limits on the maximum amount for
lump
sum repayments.
What is the Mortgage Amortisation Schedule?
A mortgage amortisation schedule is a table that shows the amount
of
principal and interest components payable monthly. As you keep paying off the mortgage, the
portion of the interest component gradually decreases, leaving only the principal component.
It
is displayed in a table format at the beginning of the mortgage.
Each row represents payment details for a single month. The rows are organised in
chronological
order, wherein the first row shows the first month's details, and the last row lists the
last
month's details. The mortgage amortisation schedule can be generated by using an
amortisation
calculator. It acts as a tracker for the borrower to monitor the amounts owed and repaid.
In straight-line
amortisation,
the interest payable is divided equally over the term of the mortgage. It is a simple method
as
the principal and the interest component payable are constant throughout the tenure.
Declining Amortisation
As the tenure of the mortgage
progresses, the interest amount payable decreases while the principal amount payable
increases.
In this case, the periodic payment is greater than the interest payment. Lower interest
rates
result in faster repayment.
Annuity Method
The annuity method in mortgage
amortisation includes numerous equal payments. Annuities can be classified as ordinary
annuities
and annuity dues. An ordinary annuity is paid at the end of each period as opposed to when
payments are made at the beginning of each period. The longer the mortgage tenure and the
higher
the rate of interest.
Balloon
In a balloon mortgage, the borrower repays
the
mortgage at maturity. The mortgage is repaid in small instalments, with a majority of the
repayment being made at maturity. As the tenure progresses, the outstanding balance
decreases
until it reaches zero at maturity.
Bullet mortgage
In a bullet mortgage, only the
interest
component is covered. At maturity, the entire principal is repaid. There is no change in the
outstanding mortgage balance during the term, and it is zeroed out at maturity.
Negative Amortisation
In this method, the total
payment
of the tenure is less than the interest payable during the tenure. Here, the interest
payable
gets accumulated and becomes outstanding.
How to Prepare an Amortisation Schedule?
An amortisation schedule contains the instalment amount,
principal
and interest payable over the mortgage tenure. The schedule is prepared in an Excel sheet.
Monthly Periodic Payments- The periodic payments are calculated via the Ordinary Annuity
method.
Monthly payment paid= I*PV/ 1- (1+i)^n
PV = present value of mortgage amount
I = interest rate
n = number of payments
The borrower has to pay interest on the mortgage amount during repayment of the mortgage.
I= P*I
P = principal
I = Rate of interest (in decimal)
Principal Amount Calculation: Interest and principal are the
components of the monthly payments. Hence, the principal amount is between periodic payments
and
interest.
For example:
mortgage: $200,00
Period: 36
Interest Rate: 6%

Monthly Payment= I*PV/ 1- (1+i)^-n
MP = 0.005* 200,000/ 1- (1+0.005)^-36
= 1000/0.16
= $6084.39
(Interest per annum is 6%. Hence, monthly interest is 0.06/12=0.005)
Interest Payable= P*I
I= 200,000* 0.06/12
= $1000
Principal payable= Monthly Periodic Payment - Interest payable
Principal payable= $6084.39 - $1000

= $ 194,915.61
FAQ's
Ans: Amortisation is the time taken by the borrower to repay the mortgage. The amortisation primarily depends upon the current year's rate of interest. The longest amortisation period a borrower is allowed is 20 years if the down payment is less than 20% of the mortgage value.
Ans: The mortgage term and mortgage amortisation can be different. Such a setup is called split amortisation.
Ans: Mortgage amortisation is easier to handle than other types of mortgages. The amortisation schedule helps you monitor payments already made and upcoming payments.
