网站新功能: 房屋按揭计算器 Mortgage Calculator

[Riven]

The PHP Mortgage Calculator tries to figure out a home
owners morgage payments, and the breakdown of each monthly
payment.

The calculator accepts:
Price (cost of home in US Dollars)
Percentage of Down Payment
Length of Morgage
Annual Interest Rate

Based on the four items that the user enters, we can figure
out the down payment ,the ammount that the
buyer needs to finance, and the monthly finance payment.
The calculator can also break down the monthly payments
so we know how much goes towards the mortgage's interest,
the mortgage's principal, the loan's Private Mortgage Insurance
(if less that 20% was used as a down payment), and an rough
estimate of the property's residential tax

Canadian mortage is similar to but actually different from the US mortgage. Our interest is compounded semi-annually instead of monthly. Compound interest basically means that it is interest on interest.

Here is the Canadian formula:

Canadian Formula

Canadian mortgages are compounded semi-annually instead of monthly like US mortgages.

Monthly Pmt =
(P*(((1+i/200)^(1/6)-1))/(1-(((1+i/200)^(1/6)))^-(n*12)))

Where:

P = principal outstanding
i = annual interest rate percentage
n = number of years


Here is a easier to read representation:

i 1/6
( 1 + --- ) - 1
200
Pmt = Principal x ------------------------
i 1/6 -12 x n
1 - [ (1 + --- ) ]
200

I'd like to use the morgage calculate on canada.com:

http://finance.canada.com/calc_amortization.htm

It will give you a nice graph to show how the principle and interest are paid, which is scary.
