@Joshua Dorkin @Brandon Turner I've searched the site to see if anyone has mentioned the following yet and it doesn't appear so. The Mortgage Payment Calculator appears to have a bug or interesting "feature". It's common for interest rates to be expressed in 1/8 increments, but the calculator rounds the entered value to the hundredths place for display purposes. More interesting is that the calculator only considers the integer portion before the decimal in the P&I calculation.
For example, if the entered amounts are Loan Amount (100,000), Loan Period (30), and Interest Rate (5.125), then the monthly P&I payment returned is $536.82. Based on my own calculator it should be $544.49.
If I change the Interest Rate in the calculator to 5.99, the monthly P&I returned is still $536.82 when it should be $598.91.
Not a big deal for anyone just browsing and using whole number interest rates, but thought you might want to know about this "feature".
*Also, as this is my first post as a new member, hello and THANK YOU for all you have contributed to BP. I guess my next stop is a more formal intro on the new member forum.
