Is it a simple interest or a compound interest?

Sure. I will start with simple interest.

Depends on the type of loan. Most U.S. mortgages, for example, use an amortization schedule (simple interest). Not sure if there should be a set default but it could be possible to offer different types of interest via javascript buttons.
For now, though, simple interest might be a good start.

If looking at US mortgages, consider Zillow's Mortgage Calculator and mortgage API.
Loan expectations will vary wildly depending on type, credit score, and country.

Believe OP is asking for a widget on the page to calculate:
P*(1 + rY) (simple interest)
P*(1 + r)^Y (annually compounded interest)
Plus an area for annual payments/monthly payments.

I am not certain how all of this information could be supplied directly to a Goodie. A search engine user would be unlikely to type "$500 a month for a $20,000 loan with 10% annual interest" to get the desired output (total paid, total interest).

Options:
"Loan calculator" could supply a widget at the top of search results.
"US mortgage calculator" could return a widget from Zillow shown here, or similar UX.

Thanks,

Hi,
Few months ago, I have used Zillow's Mortgage Calculator for calculating monthly mortgage payments such as taxes, insurance and interest. This is really an amazing tool and is very easy to use. Simply enter the home price, down payment and interest detail and get result instantly about mortgage payments.
